COMMITTEE ON AGRICULTURE, HOUSE or REPRESENTATIVES, Wednesday, December 9, 1908. The committee met at 10.30 o'clock a. m., Hon. Charles F. Scott (chairman) presiding. The CHAIRMAN. Gentlemen of the committee, I wish to say that about two weeks before the session of Congress opened I was re- quested to grant a hearing to some gentlemen who wished to appear here in the interest of the White Mountain and Appalachian forest project. It was too late, then, to communicate with members of the committee individually and hear from them, and I therefore took the liberty 'of calling this meeting, taking their assent for granted, and I am glad to note the presence of a very large portion of the committee. I understand that at a meeting held last evening of those who are interested in this matter it was decided to ask Governor Guild, of Massachusetts, to conduct the hearing. Before introducing him, however, I wish to make a few statements touching the attitude 01 the committee toward this measure, which may, perhaps, have some- thing of suggestion in them to those who are to speak. In the first place, I wish to say that the committee is fairly well educated on the general proposition. It has been discussed before us at considerable length and by very able gentlemen. In the second place the opinion of the Judiciary Committee of the House seems to leave this committee with no alternative but to ex- clude from consideration any question of the purchase of forest lands for the mere purpose of preserving the forests. Under that opinion we can only consider the propriety of such purchase in the event that a direct and substantial connection can be shown between the preser- vation of the forests and the continued maintenance of the navigabil- ity of navigable streams. Therefore, what I think the comniittee desires particularly to have this morning is facts bearing directly on this latter proposition. We want to know, if any of the gentle- men who are to appear before us are prepared to state it, just how much difference in the stream flow of some individual navigable river can be directly attributed to the deforestation of the watershed con- tributing to that stream. I think we would like to know if there is any data showing the record of streams for as long a period as possi- ble, covering a period when the forests were in existence and since they have been removed. I think we would like to know whether 200045 4 FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. the erosion, of which complaint is made as resulting in silting up the streams, is due to the removal of forests from the upper slopes or from the lower slopes of the mountains; whether it is due to the operations of farming or to the operations of lumbering. And I think also we would like to have some information, if it is possible, as to the probable price at which land can be bought in the sections under consideration, and about the number of acres that would prob- ably be required. In making these suggestions you will understand, of course, Gov- ernor Guild, that I am not seeking to dictate what the gentlemen who are to appear before us shall say. I am merely trying to indi- cate points that must be given very careful consideration by the com- mittee before it acts upon this matter. And with these introductory remarks I take pleasure in presenting to this committee Governor Guild, the distinguished executive of Massachusetts, by whose pres- ence here this morning I am sure we all feel honored. STATEMENT OF CUETIS GUILD, JR., GOVERNOR OF MASSACHU- SETTS. Governor GUILD. Mr. Chairman and gentlemen of the committee, I am sure that the petitioners in behalf of this measure for the preser- vation of the Appalachian forests will take due consideration of the kindly suggestions made by the chairman of this committee, and will, to the best of their ability, address themselves to them. I note the remarks of the chairman, that the committee has already given a number of hearings in regard to this matter and has posted itself carefully and quite thoroughly, and therefore I shall ask, to use the legal parlance, if I may put in evidence at this hearing, without read- ing, the previous proceedings before this committee with the testi- mony which you already have? The CHAIRMAN. Certainly, that will be entirely satisfactory. Governor GUILD. That is understood. I would also like to put in evidence the report of the Secretary of Agriculture on the South- ern Appalachian and White Mountain watersheds, which does give the commercial importance, area, condition, feasibility of purchase for national forests, and the probable cost, to which you referred. Furthermore, the report of the Conservation Commission, now in session, which is giving particular attention to the very practical points that the honorable chairman has suggested, in regard to the areas and to the specific effect of the destruction of the forests. Finally, I take it that you do not, of course, desire, as 1 understand, to exclude any evidence which any person now present may feel de- sirous of offering as to any deleterious effect that may come to the people of the United States from the destruction of our forests. For if we have to consider, sir, the constitutionality of this measure on the ground as to whether the waters of the river are thereby ren- dered unnavigable or remain navigable, another clause of the Con- stitution, of course, provides that Congress is to legislate for the general welfare of the people, and certainly nothing is more for the general welfare of the people than the preservation of a good water supply and a watershed for rivers that furnish water for the use of the people, whether they are navigable or not. FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 5 This movement, sir, I need scarcely say, is not of a sectional or local character. The President of the United States, in his address yesterday, declared that the one specific thing that must be done, and done now, for the conservation of our national resources, was the passage of this act for the preservation of the Appalachian forests. He even publicly advocated, if necessary, the issue of bonds by the United States for that purpose, and in that declaration *he was sec- onded by the gentleman who, if not the President-elect, is at least the President elected, Hon. William H. Taft. I suppose it may not be out of place for me to call the attention of the committee, and not in any spirit of controversy and not in any sectional spirit, to another fact. The city of Boston, the capital of the Commonwealth which I have the honor to represent, is the second port of import in the United States, furnishing, with the exception of New York, the largest rev- enue from customs to the United States Government. New England, Massachusetts, is delighted to have the National Government take up national development. The Commonwealth of Massachusetts, though we have not one square yard of arid soil which needs irrigation in our Commonwealth and have made no petition to the National Govern- ment for irrigation, yet sent its delegates to the National Irrigation Congress in New Mexico, to show that the New England States and the Atlantic seaboard are quite as much interested in providing water for the arid lands in the West as we are in providing water for the mills and streams in the East. We do not border on the Mississippi Valley or on the Ohio River, but we are heartily in accord with the movement for deeper waterways for the Central West, and our dele- gates have taken their part in the deliberations for that great purpose. We shall hope to show you here to-day that the interest which is taken in this movement and the support for it do not come alone from the sections which are to be benefited. The support for it comes from all over the United States, from the West as well as from the East, from the South as well as from the North, and I take particular pleasure ir calling the attention of this committee to the fact that I believe that this is the first occasion where the governor of South Carolina and the governor of Massachusetts, have appeared hand in hand together before the National Congress to ask for something for the common welfare of the United States. [Applause.] The effect of the shortage of water supply caused by the cutting of the trees at the head waters of the streams we shall try to show you has been wide-reaching. The diminution of water power in- creases the cost of production to our manufacturers, it increases the prices of our products, not only of cotton cloths, but particularly of paper, of which New England, as you know, is the center. It has added to the cost of the production of garden truck and the products of the farm. Finally, I shall endeavor to show you that lack of attention to these forests and the consequent low water in the streams has materially contributed to the spread of disease. The water sinking in the streams causes a deposit of sewage along the banks, and from that springs the dread plagues of typhoid fever and diphthe- ria, and certainly it is for the general welfare to prevent the death of citizens of the United States by pestilence in time of peace, as well as preserving the equipment of soldiers in time of war. Something has been said in regard to the extent to which the various Commonwealths might be expected to cooperate with the 6 FOEEST LANDS FOR THE PROTECTION OF WATERSHEDS. National Government if this new movement is crystalized by you gentlemen and jour associates into law. Some of the States have already acted. We have recently, in New England, had a New Eng- land conference of all six of the New England States, called by the six governors of New England, not merely in regard to forestry, but in regard to other legislation, that state legislation throughout New England may, as far as possible, be made uniform for all the States, and that a confusion of law may not exist. One of the topics there considered was forestry. The papers read and the discussion were submitted to the six state foresters of the New England States, and measures have already been recommended by them for adoption by all the state legislatures. In our own Commonwealth, the Common- wealth of Massachusetts, active work has already been done for the preservation of our forests. Here, for example, are some of the laws of Massachusetts which I will present to the committee, and as you will see from the cover of this little pamphlet, forest fires, especially as caused by railroads, have been made the subject of particular legislation. We have a forest warden for every city and town in the Commonwealth of Massachusetts, charged with the execution of these various laws and with the prevention of forest fires. We distribute free to the people instructions how to collect white-pine seeds and how to plant them. We furnish those to schools. We have had applications from outside of our own Commonwealth for books for children with instructions how to distinguish one tree from another, and how they can be preserved. The CHAIRMAN. As a matter of fact, the State of Massachusetts is taking care of its own forest problem with its own resources, and is not asking any consideration from the Federal Government? Governor GUILD. Because, sir, we have no great tract at the head of our great rivers which demands our particular attention. Our great rivers, the Connecticut and the Merrimac, arise outside of Massachusetts, and the amount of land which would there have to be acquired to the extent of the timber land which would have to be protected is, as seems to us properly stated yesterday by the different speakers at the Belasco Theater at the Conservation Com- mission, beyond the means of any one State to take care of. We are doing this as supplementary work to what we hope the National Government will do, and I am simply quoting this to show that we make this application in good faith, and that we are not relying wholly on the National Government. We have, for example, 23,000 acres of state forest reserves in Massachusetts. Massachusetts is not asking for any national forest reserve in Massachusetts, but she does appear here for her sister State of New Hampshire, and asks that the White Mountains shall be protected by national legislation, be- cause, as I understand, in that region some 600,000 acres will be required, and that is beyond the limits of the treasury of the State of New Hampshire to attend to. Furthermore, New England asks for 600,000 acres for her forest reserve, and she is equally anxious that her southern sisters, to the south of us, should have not 600,000 acres, but if necessary, 5,000,000 acres for the preservation of the entire Atlantic watershed and for the benefit of all the States of the * Union. [Applause.] Mr. WEEKS. It is a fact that 23,000 acres was purchased by a direct appropriation for that purpose, is it not? FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 7 Governor GUILD. Yes; the reserves, as you know. In addition to the state forest reserves, I should say we have great systems of parks in Massachusetts which also include forests. The various municipali- ties in Massachusetts are planting trees. Our highway commission in Massachusetts plant trees along every one of our Massachusetts state highways. This I am quoting merely to show the good faith in the demand for national action, that we are prepared to supplement your efforts, gentlemen, and that we do feel that the various States in which these forest reserves are located ought not to be asked to pay for them from the limited means of their own state treasuries. I appear as representing one of the Commonwealths which is to have no national forest reserve within its borders, but which will gladly contribute its share of the national revenue to establish forest re- serves, not according to political lines, where forest reserves are needed. [Applause.] I have quoted already the national character of this movement and the support that has arisen behind it all over the nation. I might close with, perhaps, a bit of sentiment, a coincidence if you please, which, nevertheless, is rather interesting. When the United States first gathered together for its war for independence, the first flag of any army from the united colonies, the flag under which Washington took command of the Continental troops under the old elm tree at Cambridge, was a white flag with a pine tree; it was the first flag of the United States Army. When the first American fleet was char- tered by George Washington at the siege of Boston, with Commo- dore John Hardy and a little fleet of fishing schooners, they flew a white flag with a pine tree, and the same motto, "An appeal to heaven." The first flag of the United States Army, the first flag of the United States Navy, under which they began the battle for na- tional existence, was the flag of the liberty tree, the flag of the pine tree. We come before vou in peace, as they went forward in war, under the same sign, for the preservation of national health and national wealth, and we ask for the preservation of forests, not in the interest of any one State, not in the interest of any section, but in the interest of the entire American people. [Great applause.] Mr. POLLARD. Governor, I do not know whether you have ever had occasion to look over House bill 22238, which is a bill I introduced on this subject. I just wanted to ask you this question. I think the committee are all agreed that the object for which you gentlemen are contending is a good one. I do not believe this committee needs any evidence to convince it that something ought to be done. What we want to know is the method, the means to the end, not the feasibility of the end itself. It occurred to me, and I have embodied the idea in this bill, that the Federal Government might, without the necessity of purchasing these tracts of land, supervise the forests and accom- plish the same end through the cooperation of the States, as you have suggested, and evade the necessity of the purchase of the lands out- right. What little investigation I have given to the subject, and I think the same holds true with some of the other members of the committee, has convinced me that if we enter into this matter, it is not a question of the purchase of 5,000,000 acres of land in the south- ern Appalachians or perhaps 600,000 acres in the White Mountains, but ultimately it means the purchase of from 65,000,000 to 75,000,000 acres of land in the southern Appalachians and perhaps 3,000,000 in 8 FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. the White Mountains, so it is a pretty big task. Now, then, if we can accomplish the same purpose without purchasing, why should we not do that? Have you given that subject any consideration? Governor GUILD. I most certainly have, but I think it will be answered later by some of the various experts on whom I shall call. But I might call your attention, sir, and no doubt it has already occurred to you, that the National Government is already protecting reserve tracts of public land, as, for example, in the Yellowstone Park. Mr. POLLARD. That is different, Governor ; that is part of the pub- lic domain. We are speaking of private land now. Governor GUILD. I understand that, sir, entirely; but it has also found constitutional means to appropriate money for the irrigation of the dry lands of the West, the furnishing of a water supply for those dry lands, and as the President and the President elected and the United States Senate have seemed to find no constitutional diffi- culty with that, and as the President and President elected seem to think it desirable even to issue bonds, if necessary, I can only say that I cordially agree with their opinions, and we will have it demon- strated in detail later. I shall now ask Mr. Finney to present various resolutions favoring this project. (The following resolutions were presented by Mr. John H. Finney, secretary of the Appalachian National Forest Association:) At the eighty-fifth meeting of this association, held at Saratoga Springs, N. Y., September 30, 1908, the following resolution was unanimously adopted : " Resolved, That the National Association of Cotton Manufacturers again recognizes the vital importance of conserving the national resources to diminish the growing evils of drought and flood and recommends the passing of laws by States and nation that will apply in correction of loss through fire, waste, and unscientific lumbering, and encourage the planting of new trees necessary to accomplish an increase in our wooded area. It has been fully established by experiences in other countries that competent forest cultivation results in an appreciable increase of timber products. " We heartily indorse the effective work of the National Commission for the Conservation of National Resources, and recommend that our association cooper- ate with this commission in furthering our mutual interests."

Whereas the preservation of forests is indispensable to the national welfare in order that a permanent timber supply may be had and that the water supply of rivers may be maintained and regulated; and Whereas the effect of denuding mountain ranges of timber is to subject them to forrential action whereby the soil is washed away, the surface rendered bar- ren, the future growth of forest trees prevented, and disastrous floods caused at certain seasons in the lower courses of the streams, with great destruction of property in cities and towns and damage to farming lands in the river bot- toms, while at other seasons stream flow is almost suspended and great damage inflicted upon manufacturing industries dependent upon water power and navigation; and Whereas the unrestricted cutting of the forests upon the White and Appa- lachian mountain ranges threatens those forests with complete destruction, whereby one of the most important sources of timber supply will likewise be destroyed, irreparable damage be inflicted upon vast manufacturing interests, particularly in the New England States, and the towns and cities in the FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. 9 drainage area of the Appalachian range be subjected to great harm from annually recurring floods of increasing volume ; Now therefore be it Rcsolrcd by the board of directors of the Merchants' Association of New York, That the welfare of the nation requires that the National Government provide, as speedily as possible, for the preservation of forests, especially in mountain regions, the regulation of timber cutting therefrom, and for the con- servation of the water supply arising in such forests with a view to lessening floods and maintaining an equitable stream flow for the promotion of agricul- ture and manufactures. Resolved, That speedy action by the Congress of the United States is neces- sary to prevent the destruction of the forests of the White and Appalachian mountain ranges and the evils incident to such destruction, and, therefore, that the Congress is earnestly requested to enact into law the measures now pending for creating forest reserves in the regions named with a view to pre- serving the forests thereof by restricting and regulating the cutting of timber and promoting new growths. NEW YORK PRODUCE EXCHANGE, New York, December 4, 1908. Mr. W. M. CROMBIE, SI New Street, New York City. DEAR SIR : At a meeting of our board of managers, held yesterday, I brought up the matter of forestry conservation and replanting, and after discussion the inclosed preamble and resolutions were unanimously adopted. I am sure these resolutions embody the sentiment of practically our entire membership, as we are all fully in accord with the desire to preserve our for- ests for the general benefit of the country. I send you these resolutions, and you have permission to use them in any way that you may deem most advantageous. Yours, very truly, WELDING RING, President. Whereas the constant cutting off of our forests, which is rapidly increasing every year, and only very limited efforts being made to restore this timber by replanting; and Whereas this destruction of our forests and woodlands is very greatly affecting our climate by the quick drying up of our streams and reducing the water supply of our lakes and rivers, thereby seriously interfering with naviga- tion; and Whereas these conditions can be materially changed for the better within a reasonable period by systematic and constant replanting and by proper reser- vation of lands for forest reserves : Resolved, That the New York Produce Exchange earnestly requests and urges the passage of one or more of the bills now under consideration by the National Congress, providing for the reservation of forests and replanting of woodlands.

It is my pleasure and privilege and honor, as vice-presi- dent of the Southern Commercial Congress, to present to you a reso- lution adopted yesterday, which reads as follows : The Southern Commercial Congress in convention assembled, with accredited representatives of 64 commercial organizations from the 15 States participating therein, does resolve as follows : Deeming the establishment of the proposed Appalachian White Mountain National Forest of paramount importance to the nation, and realizing the ur- gent necessity of immediate congressional action thereon, we commend the Senate in passing the bill ; we deplore the delay of the House of Representatives and its Agricultural Committee in withholding favorable action upon it; and we unite, as earnest and patriotic believers in the utmost conservation of our national resources, of which the forest is certainly one of the most important, in this expression of dissatisfaction in any further delay. And we further instruct the chairman of this congress to appoint a committee of this body to attend the hearing before the Agricultural Committee on Wednes- day, December 9, and to express in no uncertain terms our attitude in this matter. Governor GUILD. I have asked pur representatives here to-day to confine their remarks to the five-minute limit, and with your consent, sir, shall notify them when their time has expired. The CHAIRMAN. That will be satisfactory to the committee, with the understanding that, in fairness to the gentlemen appearing, if the committee protracts their time with questions of its own the limit will not be enforced. Governor GUILD. We appreciate your kindly courtesy, sir, and merely desire to reciprocate. As the first speaker, especially as he is obliged to attend duties in the Senate chamber shortly, I shall call upon the Chaplain of the Senate, the Rev. Edward Everett Hale. STATEMENT OF DR. EDWARD EVERETT HALE, CHAPLAIN OF THE UNITED STATES SENATE. Doctor HALE. The reason why Governor Guild calls upon me is that I am the oldest person hereabouts who has really worked in the New Hampshire forests. I had the good fortune, when I was 19 years old, as a boy, to serve on the Geological Survey in the State of New Hampshire. I have slept under these very pine trees which have long ago been cast down, and within two years I went over the absolute ground, where there was not a stick as big as that stick I have to lean on now. It makes a man cry, when he has slept under a pine tree 10 feet in diameter. I have talked with men who saw George the Third's " broad arrow " on trees, which the King would never per- mit to be cut down and now to see the places where they grew grow- ing up in blackberry bushes. I respect entirely what the chairman has said as to the nature of the testimony desired by the committee, and I will try to confine myself within that limit. When I was here a year ago the question had not been raised, even as an academic question, as to the right of this committee to do any- thing about it. The chairman informs us that it has been raised since. I went from this room then and addressed a note to the Navy 12 FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. Department and to the Land Office, and asked them to send us the particulars about the purchase, more than one hundred years ago, by the Navy Department, of lands at the South, because they had live oak upon them/from which the department wanted to build our frigates and vessels. The Land Office and "the Navy Department together were kind enough to furnish those documents, and they are the evidence that more than one hundred years ago the nation was in the habit of buying land, owning land in fee simple, from different States and from different individuals all through the South be- cause it had live oak upon it, and that covers completely every state- ment which gentlemen have wished to make here with regard to that. Those papers can be obtained by the chairman and by yourselves. Speaking about denudation, I do not think there is any lesson that the committee can learn outside of the hills of New Hampshire them- selves as to what we mean by denudation. In the old days, of which the governor has spoken just now, these pine trees were employed in the American Navy. Mr. Chairman, in the great battles of 1780 and 1781, when the British navy was engaged, when the American Navy was engaged, when the French navy was engaged, when the Spanish navy was engaged, every spar used by every frigate, prob- ably, and every man-of-war was from the New Hampshire and Maine forests. Up until 1775 the export of these spars had been necessary, and every navy-yard in western Europe and every fleet in all the great naval encounters flew their flags from flagstaffs supplied from the New Hampshire forests. In the last ten years, I was going to say, there has not been a spar as big as that cane sold from a New England forest, and why is it? It is because in the present business of lumbering the very paper you are writing upon is made from spruce timber cut down up there. A lumber baron will send his men in, and he says, " Oh, do not pick out the good trees ; cut down everything." It is so much easier to clear the whole thing, make a clean sweep of it, that the denudation goes forward as it did not go forward in the days when I was a surveyor there. In those days the man who sold lumber sold timber which was of use to cut up. Now, if he can sell a stick as big as my arm he can make as good paper out of that stick as he can make out of a big log, and therefore the in- structions to the workmen are to cut down everything and to leave nothing. * Then comes a God-appointed shower, and the shower washes off everything, because you have nothing to hold back the water. It washes off everything. It washes off all the soil, everything that will go. It washes off everything but large stones. So, when Governor Guild and I go up there with our nice pine seed and plant them there they will not grow. You have swept away the soil, and you have nothing left but gravel and rock. The plea, therefore, for the preservation of the forests, that has now become a national plea, is a plea made necessary on account of the uses made of the timber when it has been cut down, and I beg that you put in as a part of the statement we make that the cutting down of the forests now leaves the thing as bare as that table, you might almost say, and it sweeps down the soil, and the governor has told you what becomes of it. It lies on the shores of the rivers and creates malaria and all those evils. FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. 13 The precise position of the State of New Hampshire has been alluded to. I am a resident of that State every summer; in fact, I officially represent here a body of the people of one of the valleys there, who were kind enough to make me the chairman. That State, the chairman must remember, includes not only the waters of the Connecticut Kiver, but the waters of the Androscoggin River, which rise in the State of Maine. I do not think, Mr. Chairman^ that anybody had dreamed, when I was here a year ago, that this com- mittee had not full power to act in that purpose. I think it was an academic question which came up afterwards, when our friends say the Judiciary Committee sent down to you and said you could not do certain things which you wished to do. But it seems to me that the question of the live-oak lands is an interesting one, and it shows that the people one hundred years ago thought they had that power, and if that does arise, it shows that the conditions of timber cutting are wholly different from what they were one hundred years ago. I see the chairman looking at his watch, and I only allude to the question of the bonds, and if you will fix it so that the Government will take care of the forests as Bavaria and other European countries have, fifty years hence you will have a larger revenue from your forests and you will pay "f or your bonds with them. STATEMENT OF HON. JOHN H. STEPHENS, A REPRESENTATIVE IN CONGRESS FROM THE STATE OF TEXAS. Mr. STEPHENS. Mr. Chairman, I desire to state that I have a bill on all fours with the Appalachian and White Mountain bill, for protect- ing a natural forest growing on the headwaters of the Red River in the plains of Texas, extending almost to the eastern side of New Mexico. We have organized, in the southwest four States, into a congress known as " The Red River Improvement Association." We passed resolutions requesting that 100,000 acres of land be purchased on the headwaters of the Red River for the purpose of protecting the forests there, and the conditions will not exist as described by the last speaker if Congress would purchase this land and protect the timber there now, which will not require being replanted. Neither will the conditions exist that exist at present in the Southern Appalachians, but the land has passed from the State of Texas ; it no longer belongs to us. One-half of it was given for the purpose of building interstate railroads running across the continent, the Texas Pacific and the Southern Pacific, and that is the reason we have not any public do- main left there, mainly because we gave away one-half of it for the purpose of building our railroads. So we now ask that the Govern- ment appropriate $500,000 for the purpose of purchasing 100,000 acres of land as a forest reserve and a park on the headwaters of that river. This is joined in by all of those States and by various cities and towns and various associations, and I will now ask leave to file these, together with the numerous maps and documents obtained from the Forestry Bureau and other documents of interest in this matter, with your com- mittee for your investigation. The CHAIRMAN. Without objection, the papers will be filed. 14 FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. Be it remembered that at the second meeting of the Red River Improvement Association, held in Denison, Tex., on November 6, 1908, the following resolu- tion was unanimously adopted : " Resolved, That we favor the passage of the bill now pending in Congress to create a national park and timber reserve in the canyons forming the head of Red River, believing the preservation of the forests to be essential to the improvement of Red River." Respectfully submitted. JNO. H. STEPHENS, Author of bill referred to, etc. To the chairman Red River Improvement Convention: We, your committee on forest reserve, beg leave to submit the following report : Whereas this convention, recognizing the great natural resources of the Red River Valley and of the paramount importance of restoring navigation on the Red River, not alone to the people along said river, but to the nation as well, and of the importance of preserving and fostering of the native timber at the head of and along said river and its tributaries ; and whereas the Hon. John H. Stephens, Representative in Congress from the Thirteenth District of Texas, has introduced in Congress a bill seeking to have a national park established in the Palo Duro Canyon, in Randall and Armstrong counties, Tex., on the head- waters of Red River. Therefore we indorse said bill and recommend that the same be passed by Congress at its next session, and further recommend that this association take steps to encourage the people along the Red River and its tributaries in systematically preserving the natural forests along said stream and its tribu- taries and engaging in fostering the growth of timber as well. We further recommend that the secretary of this organization be requested to furnish a copy of this document to the Senators and Representatives in Con- gress of the States of Texas, Oklahoma, Louisiana, and Arkansas and request their united efforts in support of the above measures. Respectfully submitted. J. W. CBUDGINGTON, Chairman, Amarillo, Tex. HENRY Cox, Fulton, Ark. H. P. MAYEB, Paris, Tex. S. R. CBAWFORD, Graham, Tex. J. B. LEEPEE, Denison- Sherman, Tex. H. G. EVANS, Bonham, Tex. HUGH COREY, Alexandria, La. R. D. BOWEN, Pan's, Tex. Mr. STEPHENS. If the governor of Massachusetts will permit me, I will inform him that the governor of Texas will take pleasure in joining with vou and with the governor of South Carolina, and with greater zeal, because she is much larger than all the Southern States and all New England combined. [Laughter.] Governor GUILD. And you might add one more thing, that the other States joined together to make a nation, but Texas as an inde- pendent nation joined the United States. Mr. STEPHENS. The gentlemen must remember that Texas annexed the United -States. Texas was an independent government itself, and I always contend that Texas annexed the United States, and not the United States Texas. [Laughter.] Governor GUILD. There is no compliment which you can pay to the Lone Star State which we of New England will not take pleasure in joining with you. I take pleasure in presenting as the next speaker a gentleman who is obliged to leave very shortly, and I therefore will introduce him out of order, one of the governors of the West. I take pleasure in presenting Governor George E. Chamberlain, of Oregon. FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. 15 STATEMENT OF GOVERNOR GEORGE E. CHAMBERLAIN, OF OREGON. Governor CHAMBERLAIN. Mr. Chairman and gentlemen, I am here at the request of some of the distinguished gentlemen from the Northeast to join with them on the part of the Northwest in further- ing this movement. I desire to say that Oregon has at least one-fifth, probably a little more than one-fifth, of her area in the federal reserves, and that area embraces the most magnificent forest reserves of the whole western country. Until the Government established these reserves and took control of them there was very little done toward forestry protection, but since the Government has taken charge these forests have been better preserved, trespassers are in greater fear of the Government than they ever would be of any of the state authorities, and the results there are splendid. I want to say that I believe that some policy ought to be taken by Congress to acquire, not in the name of the State, but in the name of the United States, those deforested areas, not only in the Northeast, but along in the Appalachian Range as well. The suggestion has been made that possibly the same end might be subserved if the title remains as it is, or possibly in the State with federal supervision, but it seems to me that in order to accomplish results these lands ought to be purchased by the Federal Government, either by agreement with the parties who own them or by the exercise of eminent domain, if that can be done, and I think it can be. Not only will it be necessary for refor- estation of the deforested areas, but it seems to me it will eventually become necessary to expropriate, if I may use that term, the ownership in the water powers as well as in the deforested areas. So I want to say that the Northwest heartily joins in this movement, and I think that the Government, if it does not do it now, will be compelled in the very near future, for its own protection, to buy these areas. Governor GUILD. I need scarcely remind you gentlemen that Gov- ernor Chamberlain spoke for the governors of all of the United States in response to the address of the President. I present as the next speaker the president of the University of Wisconsin, Dr. C. R. Van Hise. STATEMENT OF DR. C. R. VAN HISE, PRESIDENT OF THE UNI- VERSITY OF WISCONSIN. Doctor VAN HISE. On yesterday afternoon I had no expectation of saying anything in reference to this matter to the Committee on Agri- culture, but the men who are especially interested in this measure in the southeastern part of the United States asked me to say a few words in reference to the condition of that part of the country. As a member of the Geological Survey for a number of years I had charge of the work in that region, and therefore traveled extensively over it all the way from Virginia to Georgia. I am therefore some- what familiar indeed very familiar with the actual situation in that region. I am not going to undertake to present the details upon which the conclusion is reached that this upland region should be reserved as a forest, since I understood one of the members of the committee to say that that point was already conceded; that it was admitted that it was extremely desirable indeed, almost necessary that this great upland region be reserved as a forest. 16 FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. However, there is just one point in connection with that to which I wish to call your attention. It is this, that this region is one in which the conditions are especially critical. In the northeastern part of the United States and I am not talking against the White Moun- tain reserve, for I believe in it in the northeastern part of the United States, or in the northern part of the United States, below the sur- face there is a sand and gravel which makes a porous stratum which carries water. In this southeastern part of the United States the rocks have not disintegrated and are nonporous; there is clay. The water does not readily find its way into them, and the result is that it gathers upon the surface very readily and very easily into streams of considerable power, and is therefore' especially potent in this matter of erosion. Every one of you who is at all familiar with the region in the southeastern part of the United States must have appreciated how much more extensive the erosion is in that region, even on slopes of moderate steepness, than it is in these other regions in which the conditions are less crucial, and therefore I wish to urge that in this particular the southern Appalachian forest region has an exceptional demand for attention. I unhesitatingly assert that somehow, for the good of the States and the nation as a whole, it is absolutely necessary to preserve the protective covering of vegetation on this upland area of the southeastern part of the United States. But that I understand to be conceded, and therefore I shall not dwell upon it. So that the question comes back, How can this great task be accomplished ? Why should the Government undertake a portion of its accomplishment ? In the first place, it is a tremendous task ; a task of such magnitude that to properly accomplish it will require, it seems to me, the joint efforts of the nation, of the States, and of the citizens. But if it is merely a local interest, why should the nation participate? And that, of course, is the crucial question, from your point of view. It seems to me there are two very good reasons, one of which has been sug- gested to me since I came into this room, why the nation ought to par- ticipate, why they will find it economical to participate in this mat- ter. In the first place, the nation is taking up the question of improving its waterways, to maintain a uniform and equable flow. There is talk of spending not five millions, or ten millions, but scores of millions of dollars in the improvement of inland water- ways. This vast expenditure which is necessary can be reduced, in my judgment, and I think if time were sufficient it could be proved that it could be reduced if the problem is studied at the head in- stead of the foot ; that is, if the forests are preserved, if the covering vegetation is preserved, a uniform and equable flow of the streams is produced. The question may be asked, Is it a fact that in consequence of the removal of the forests floods have increased ? Does the water go down more rapidly at one time and less rapidly at another in consequence of the removal of the forests ? In reference to the Tennessee River, one of the long streams which heads in this region, that is unquestion- ably true. The most careful investigation which has ever been made in this country upon the relation of forest covering to stream flow has been made by Mr. Leighton of the United States Geological Sur- vey during this past summer. This investigation has taken into ac- count not only the number of floods during the past twelve years and the previous twelve years, but the number of flood-producing FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. 17 rains, for an investigation which does not take into account the num- ber of flood-producing rains is very imperfect. I can not, of course, in the five minutes time present these results in detail. I will sum it up in a sentence and leave the question to be proved by Mr. Leigh- ton in case you desire it, but the result of his investigation shows that as a consequence of the change of conditions due to deforestation during the past twelve years the floods are 18.75 per cent more fre- quent than they were during the previous twelve years, taking into account the precipitation, the number of flood-producing rains, as well as all the other factors. This is the first investigation which has been made, and this investigation concerns directly this southern Appalachian forest reserve. . Now, the second point is this : The Government spends millions of dollars in dredging out harbors, and yet no effort is made by the Gov- ernment to prevent the silt from going down into harbors and filling them up, and so that process goes on year after year and year after year and must continue to go on, because it will never be possible to altogether prevent the silt from going down into the harbors. The CHAIRMAN. Has it not always gone down? Doctor VAN HISE. It has always gone down. The CHAIRMAN. Does not the location of the great bar at the mouth of the Columbia, which has existed ever since navigation discovered that access, indicate that there has been very severe, erosion through that watershed from time immemorial, and extending through a time when the watershed was just as perfectly protected as it ever could be by forests? Doctor VAN HISE. That is entirely true. There never will be a time in which the silt will not be carried down into the harbors and rolled over and over and carried along by the waves meeting the cur- rent. There never will be a time when that is not the fact, and there never will be a time in which the harbors will not fill up. But the amount of silt that is carried down from the mountains has been vastly increased as a result of this deforestation. The CHAIRMAN. Is that merely a deductive opinion, or is it a demonstrated fact? Doctor VAN HISE. It is a demonstrated fact, as it seems to me, from the results of these very investigations that have been made with reference to the Tennessee. There is no question on the part of any- body that the erosion in the South and in the headwaters of these streams, as the result of the removal of the forests, has gone on at a speed which never occurred before. That is to say, before the forests were removed the forces of nature were making the soil faster than it was being washed away, so that the soil was ever getting thicker and thicker and thicker. Wherever the forests have been removed, and especially on the steeper slopes, erosion has gone on faster than the making of the soil, so that the bare rocks are protruding, conclusive proof that there has been carried down with the streams, and ulti- mately to the mouths of the streams, much more material than was carried down under conditions of forest cover. The CHAIRMAN. Has any investigation been made to determine what proportion of the soil, eroded from the slopes at the headwaters of a stream like the Tennessee, reaches the navigable portions of that stream ? 72538 AGR--09 2 18 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. Doctor VAN HISE. There will be a direct relation, unquestionably. It will not reach it at once. Of course the silt picked up high in the mountain is carried part of the way down with this flood and it is dropped on the way; then another flood comes along and it is carried a little farther down and dropped again, and ultimately it either reaches the outlet and fills the harbor or else flows over its banks and destroys the farming lands, as in California, where sand and gravel have been distributed over the lowlands as a result of hydraulic min- ing operations. I do not hesitate to assert that the silt and loosened material that goes down in the Appalachian and White Mountain regions, if those regions were denuded, would be fully one hundred times as much as has been washed down in the rivers of California as a result of hydraulic mining operations. The CHAIRMAN. You are very familiar with the Southern Appa- lachians ? Doctor VAN HISE. Yes, sir. The CHAIRMAN. In your opinion has the erosion which has thus far taken place come from the operations of lumbering or from farming? Doctor VAN HISE. Mainly from farming as yet, but of course it is' a twofold thing. It naturally happens that when the timber is re- moved it is removed from the more accessible areas. When once it is removed from an accessible area that accessible area will be made into a farm. Combination of the two results in the erosion. Undoubtedly there have been mistakes in this particular. Some areas from which the timber has been removed, or removed in part, should never have been made into farms. They are too high up, the slopes are too steep, so that the erosion goes on with excessive rapidity, and therefore it can not be asserted to be one or the other ; it is the result of both. The CHAIRMAN. Very large sections of the Appalachians have been lumbered. All the valuable merchantable timber has been taken out. In such sections have the lumbering operations gone to the extent of contributing very greatly to the erosion? Doctor VAN HISE. I think they have. I want to be perfectly fair and express the things in absolute proportion. I do not believe that the lumbering operations alone, m case the lands had not been farmed afterwards, would have resulted in as great erosion as has resulted from the farming operations after it on lands not' adapted to farming. The great difficulty has come as a result of lumbering operations followed by farming operations on lands that never should have been taken for farming. The CHAIRMAN. You know, of course, that the clearing of the slopes for farming in the southern Appalachians has been under the compulsion of necessity. Men have been obliged to find some place upon which to earn a living, and they have cleared certain of the most accessible slopes. They have not deliberately and with malice aforethought gone and taken the steep and almost inaccessible slopes when other land was available. We are obliged, therefore, to take into consideration the conditions that exist and which have resulted as a mere incident of civilization. Remembering that, and remem- bering, as I think we also must, that the people of North Carolina, for example, must continue to live in North Carolina we can not depopulate the State and send it back to the wilderness I would like to ask you, if you were commissioned by the Government to buy land in North Carolina for the conservation of the stream flow, would FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 19 you purchase the lower slopes or the upper slopes of the mountain ? And I want your scientific opinion. Doctor VAN HISE. I shall give you my best judgment of the mat- ter. My principle of action would be this : Upon the whole, from the point of view of the nation, is this land more valuable to the nation for agricultural purposes or for the purposes of forestry and the regulating of the sCTlams? If, upon the whole, that land, using the best data and judgment, if the slopes were such, the soils were such, the conditions were such that the land could be used for a reason- able length of time, with care practically perpetually, for agricul- tural purposes, certainly it should be used for agricultural purposes. But if the slopes are so steep that that is not practicable; if the slopes are so steep that it is not economical to do that; if the slopes are so steep, as in the Balsams, for instance, where the land will be gone in five years, that never should have been allowed to become an agricultural tract, and if under those circumstances that land has become an agricultural tract, it should be reconverted into a forest tract. The CHAIRMAN. Governor Guild, let me say aside, you will pardon me for taking this time with Mr. Van Hise, but it is because we know he is an expert on this question, and I think we can get some informa- tion, and I am sure the committee will extend the time. Governor GUILD. Certainly, Mr. Chairman. The CHAIRMAN. Now, Doctor, leaving out of account the question of the rights or the necessity of the people to live in North Carolina, as a scientific proposition, if you were commissioned to buy the land and had to take your choice between the lower third and the upper two-thirds of the* ranges, and your only purpose in buying it was to conserve the stream flow, which would you buy? Doctor VAN HISE. I would buy the headwaters of the streams. The CHAIRMAN. You do not understand my meaning. I say. Would you buy the lower slopes of the mountains or the upper slopes, assuming that you could not get both, but that you would take the one which would most conserve the stream flow? Doctor VAN HISE. I can not make quite a satisfactory answer to that, because the erosion depends on two things on the steepness of the slope and the volume of the water; and, of course, the lower down the slope you are. the heavier the volume of water is. There- fore those uplands which should be selected first should be those up- lands in which the slopes are so steep that if converted into agricul- tural lands they would be p'ractically destroyed, but low enough down so that they would be where the erosion would be likely to be the greatest. I would not select the tops of the mountains, the flat tops, because the lands on the top there would not be so easily washed off because they are flat, in the first place, and because, in the second place, the stream currents are not strong. But after you get over the top and down these slopes here and the streams have gotten the volume so that the erosion would be great and the slopes are steep there; joining those two factors together and picking out the area in which the damage would be the greatest by the removing of the for- ests; those would be the areas which I should select if it were left to me. The CHAIRMAN. Suppose I had a cone here approximately the shape of a mountain, sitting in a panfull of water: suppose I tie a sponge 20 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. tightly about the upper two-thirds of that cone and sprinkle lamp- black over the lower third, and then have an artificial rain falling on the whole cone. The water in the pan would be discolored immedi- ately, would it not, by the washing of the lampblack? Doctor VAN HISE. Undoubtedly. The CHAIRMAN. Supposing now we reverse the situation, sprinkle the lampblack over the upper two-thirds and bind the sponge tightly on the lower third of the cone, then have your artificial rain; is it not likely that the sponge would serve as a sort of filter and hold a lareg proportion of the lampblack, and the water would not be so discolored ? Doctor VAN HISE. That is so, but I would question, if you may permit me, the applicability to the case. This lower land is not a sponge, but it is, as I have explained, impervious, relatively, and is soft enough so that it can be removed. The CHAIRMAN. All the advocates who have come before us have compared a forest to a sponge. That is the reason I used the illus- tration, and my application of it was this : That with the forest sponge upon the lower slopes of the mountain, any erosion from the upper slopes was much more likely to be retained and held and not to get into the streams than if the upper slopes should be protected and the lower slopes left bare, because then when erosion begins there is not anything to filter the water, and it carries its load of soil into the stream. My observation through that country has been that erosion always takes place, if the lower slope is bare, no matter what the declivity may be, and no matter whether the upper slope is covered or not. It does not Always take place if the upper slope is bare, while the lower slope is left covered. Doctor VAN HISE. I would not dissent from that. I did misunder- stand. I feel I am taking too long a time, but I would like to put the actual conditions before the committee. The cone does not cover the case, because the mountains are not cones. The mountains are mainly flat-topped ridges and valleys. Supposing this to be a moun- tain [illustrating]. The condition is represented by that kind of a curve. You start with a flat top, in that way, and you go down the curve, getting steeper and steeper. The Hogarth line of beauty rep- resents the curve of the valley to the top of the mountain. I would quite agree with the chairman of the committee that this part away up here would not be the part that is most eroded, because the streams have not gathered sufficient volume, nor would the valley lands, which would be this belt in between, where the streams have gathered suffi- cient volume to become powerful and where the slope is steep. If you premise here a belt, the forest being down here, it will in a measure stop and check the work of erosion that is going on higher up. The CHAIRMAN. That being true, does it not follow that if you are going to protect the hills, and in that way protect the streams from silting up, you must keep the forest cover on the intermediate slopes that vou speak of, rather than on the upper slopes? Doctor VAN HISE. Yes, sir. The CHAIRMAN. If that is true, the suggestion which has always been made before this committee, and which is the whole burden of the report from the Secretary of Agriculture last year on this ques- tion, that we must preserve the upper slopes, has proceeded upon a mistaken hypothesis? FOEEST LANDS FOR THE PROTECTION OF WATERSHEDS. 21 Doctor VAN HISE. Of course, as I understand it, this bill does not des- ignate the particular lines to be selected. It is to be supposed that the Secretary of Agriculture, in case* the bill is passed, would have that selection made by men who best understand the forestry and erosion, and therefore, we think, would select the lands which, upon the whole, are best adapted to this end. I perhaps would not put it so strongly as the chairman and say the lower slopes, but I would say, on the general principle which you have in mind, that this interme- diate area, which combines volume of water and steepness of slope, is the most crucial and dangerous area, and it would be very greatly aggravated and might be worse farther down here were the forest removed. The CHAIRMAN. And that area which you speak of as the crucial area is crucial right now because it has been cleared and is used as farming land ? Doctor VAN HISE. A part of it is crucial on that account, but there is a lower part that has not been cleared. These steeper slopes have not been cleared. The CHAIRMAN. Oh, to be sure, there are places where the crucial slopes have not been cleared; but the ones we are speaking of now, those having the effect on streams are those which are being used or have been used for farming purposes? Doctor VAN HISE. Yes. The CHAIRMAN. So, if we are going to take possession of them, we must dispossess men who are using them for farming purposes? Doctor VAN HISE. I answer yes in every case in which land upon the whole is so badly located that it can not be maintained as a farm successfully, and is better adapted to forestry than to farming. That is the practice we have in Wisconsin. The commission goes to work there and we use our best judgment. We say, " Is this par- ticular tract better adapted to agriculture or forestry?" and studying that particular tract, if we consider its soil, slope, and everything are better adapted to agriculture than to forestry, we sell it for agri- cultural purposes and use the money to buy land suitable for forestry purposes. On the other hand, if the land, by its location, by its character, is better adapted, upon the whole, to serve the State as forest than as farm, we change it into forest, even if it be a poor farm, and we are doing that thing now. The CHAIRMAN. You can do that where the land does not belonff to anybody who is making a home on it, but do you not apprehend a little difficulty in securing the land that you would have to acquire from people who have lived on it, and perhaps their fathers before them, for several generations? Doctor VAX HISE. We do not pay any attention to that. The CHAIRMAN. We are obliged to pay attention to it. Doctor VAN HISE. It seems to me, of course, that the interests of the State and the nation are superior to those of the individual. The CHAIRMAN. Pardon me. We must bear in mind all the time our responsibilities as legislators; and would you recommend that this committee favorably report any measure which, for its successful carrying forward, must take with it the authority of some govern- ment official to determine whether a given tract of land is more valu- able for forest purposes than for farm purposes, and if he decides that it is more valuable for forest than for. farm, give him the 22 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. authority, under eminent domain or some power of condemnation, to compel the owner of it* to part with it ? Doctor VAN HISE. I answer yes to that, unqualifiedly. Mr. STANLEY. Excuse me, Doctor, do you proceed upon the theory that the Federal Government would have the same right and has the same jurisdiction to take the land by a process of eminent domain, belonging to private individuals, on account of its better adaptability to forestry than to farming, that a state government would have ? Doctor VAN HISE. If necessary to protect the equable flow in the waterways, and therefore to protect navigation effectively and cheaply, and if necessary in order that the harbors shall not be filled up, if necessary for watershed for that purpose, then I say yes. Mr. WEEKS. You speak of the State of Wisconsin purchasing land and setting it aside for forest purposes. Has the State expended any money for this purpose which has not been obtained from the sale of state lands ? Doctor VAN HISE. No large amount. We have a small appropria- tion which we can use for that purpose and can invest in tax lands, but we are going to ask a much larger amount for that purpose, and we have every reason to suppose we shall secure a larger amount, but our start was on the basis of the state lands going to the commission, with the power to sell and to buy, using the money which we obtained from selling to purchase. Mr. WEEKS. Has there been a criticism of that process of procedure ? Doctor VAN HISE. Substantially none, because we have been ex- tremely careful to dispose of the lands, which really are agricultural. We have tried to interpret that feature of the act fairlv. If it was a very reasonably clear case that the land was really agricultural land, and a man said, " I want that land for agricultural purposes," and our experts showed it was really adapted to agriculture, we would adver- tise and sell it to him, even if it involved a special advertisement and sale. (Thereupon, at 11.50 o'clock a. m., the committee took a recess until 1.30 o'clock p. m.) COMMITTEE ON AGRICULTURE, HOUSE OF REPRESENTATIVES, Wednesday, December 9, 1908. The committee met at 1.30 o'clock p. m., Hon. Charles F. Scott (chairman) presiding. The CHAIRMAN. All the members of the committee are not here, but, as the record is printed, they will have access to it, and I do not wish to delay the hearing any longer. May we ask to have Doctor Van Hise take the stand again for a few moments only? Governor GUILD. Possibly, to save a little time and answer some of the questions that have been put forward, it may be frankly admitted at once that the acquisition of forest reserves would dispossess some mountain farmers of their farms, but thereby not only is the infi- nitely greater number of farms lower down on the river, which would otherwise be sterile, rendered fertile by water, but thousands of times the number of people can be supported in cotton mills run by the water power thereby obtained than could be supported on the few farms which it might be necessary to have taken. FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. 23 Then, in regard to the question of the form of mountains. I believe that matter is thoroughly discussed in the proceedings of the con- servation commission, which will be available to you, and, as I under- stand this bill, it is a flexible bill, by which whatever portion of land that would be necessary might be taken, and in some instances it might be the extreme tops of the mountains and in others the inter- mediate slopes. The CHAIRMAN. Governor, it is true, as you say, that the bill which was passed by the Senate is a flexible bill, and yet the reports which have come from the Forestry Bureau, and practically all of the argu- ments which have been made before this committee, have urged that it is the upper slopes of the mountains that need to be protected, leaving the inference, of course, that the lower slopes, which are now cleared off for farming, are not necessary to the success of this project. It rather seems to me, therefore, that if the fact should be developed that it is the 'lower slopes and not the upper slopes that are important to the project, our confidence in the judgment of those to whom we have looked for guidance in this matter must be severely shaken; and furthermore, if it should be developed that it is the lower slopes and not the upper slopes that must be safeguarded, it will be at once conceded that the cost of the project will be enormously increased. We have been urged to pass this measure upon the theory that be- cause it is the inaccessible upper slopes that are needed we can get them cheaply, but we know that if it should prove to be the acces- sible lower slopes that are necessary, those can not be gotten cheaply, and, you see, it makes a vast difference. Governor GUILD. I quite understand. The CHAIRMAN. That was the point of my inquiry. Governor GUILD. I quite understand it, sir, and it was a fair in- quiry, unquestionably; but the point I wished to establish was, that it is practically impossible, as I understand it, to establish an absolutely hard and fast rule that in no cases must lower slopes be taken. Furthermore, one other point I wished to put in was in regard to the constitutionality which was put here, that eight Southern States and two Northern States, Maine and New Hampshire, have already passed enabling acts in regard to the right of eminent domain, by which the State practically invites the National Government to come into those States and exercise that right for the purpose of forest reserve. Mr. POLLARD. Now, Governor, if that is the case, and there is a general disposition among the States that are covered by these moun- tain regions in question, why is it not just as feasible for the Govern- ment to come in and cooperate with those States and exercise the right of supervision instead of purchasing the land? Governor GUILD. I would state that the governor of California, who has had some practical experience on just that point, will answer that question later. Mr. POLLARD. It seems to me if we would have a cooperative ar- rangement between the Government and the States, or desire to co- operate, we might find a solution in that way and not purchase the land. Governor GUILD. The first part of your proposition I think I have already answered, or at least I have tried to, by saying that the States are perfectly willing to cooperate, and are cooperating, and in our Commonwealth of Massachusetts, for example, where we are asking 24 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. for no reserve land, we are cooperating on the lower reaches of the rivers and spending our money to a certain extent; but, as I stated before, the State can not possibly out of its limited treasury be ex- pected to provide for the large tract of land that would be required at the headwaters of the rivers. Mr. POLLARD. I fully agree with you in that, but through a coopera- tive arrangement, the States being willing, could not the Government exercise the right of supervision in those States and obviate the necessity of purchase? Governor GUILD. I do not think it would be possible, sir, to obviate the necessity of expenditure from the National Treasury. Mr. POLLARD. You do not understand my question. Governor GUILD. Possibly not. Mr. POLLARD. I did not mean that the expense should all be shoul- dered upon the States. I meant that the Government should share its proportion ; but to obviate the necessity of purchase, permit the forest lands to remain in the hands of the present owners and permit the Government to go in there and cooperate with the States, with their permission, which I understand would be necessary, and then we would exercise the right of supervision, the Government bearing a portion of the expense, or, so far as I am concerned, I would not object to its bearing all of it, and accomplish the same end, but obviate the necessity of purchase. Governor GUILD. I do not think that could be obviated, sir. We have had practical experience in my own Commonwealth, and we have actually bought out of the state treasury tracts of forest lands and established them as reserves in the Commonwealth, and mere supervision of the land has not seemed to be possible. But if you will pardon me for a moment, sir, we were in the midst of some expert testimony, and I am afraid we are getting off the track. Mr. POLLARD. The reason I asked the question was because it bore directly on your statement. Governor GUILD. I thank you very much. STATEMENT OF DR. C. R. VAN HISE Continued. The CHAIRMAN. Doctor, if you will permit me, I would be glad to ask you two or three more questions developing facts along the line we were discussing before the adjournment. When a slope has been cleared and farmed until it is so eroded as to become useless for farming, what becomes of it under present conditions? Doctor VAN HISE. Under present conditions it does and would, in most humid areas, reclothe itself in time with vegetation, and finally with timber, but that frequently will not happen until the disinte- grated material is practically all gone down into the streams and there has been very extensive wash. But in general it is true I do not wish to in any way avoid, the difficulties that in these humid areas, if there is any soil left, they" trill reclothe themselves with vegetation. Governor GUILD. After how many years? How long does it take? Doctor VAN HISE. Of course it depends on whether you mean just the shrubbery or mean trees. Governor GUILD. I mean trees. FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 25 Doctor VAN HISE. Of course many years for trees, and they have very much less favorable conditions than the first time because of the fact that they would have bare rock and a very scanty soil instead of abundant soil. The CHAIRMAN. How long does it take to bring back the cover that will prevent erosion and retard a run-off. Doctor VAN HISE. Usually, if there are no fires and if the streams are not too powerful, it will have begun to get a tangle of under- brush within five years. The CHAIRMAN. I would like to say right there that I have seen a great many slopes where the erosion has been very bad that were com- pletely reforested, so far as the creation of a cover to prevent further erosion was concerned, in much less than five .years. Then there is an inevitable cycle, is there not, beginning with the forest and end- ing with the forest, with a little period of farming in between ? Doctor VAN HISE. There is where I should not accept the state- ment. There Is- an inevitable cycle if we take lands for agricultural purposes that never should have been taken for such purposes. The CHAIRMAN. But we are assuming conditions to be as they are. Doctor VAN HISE. But if lands are not taken for agricultural pur- purposes which should not have been, there is not an inevitable cycle ; there can be continual preservation of the disintegrated surface and continual forest cover. The CHAIRMAN. Of course the point I have in mind is simply this: It has been brought out that the trouble we are now suffering, has come from the clearing of the land for farming purposes and not from the lumbering operations. Doctor VAN HISE. Partly from each, but more largely from farm- ing. The CHAIRMAN. More largely from farming. Doctor VAN HISE. That is entirely true. The CHAIRMAN. More largely from farming than from lumbering. That being true, it has occurred to some of us that the situation was one which carried its own remedy; that even if the lower slopes were cleared off, as they have been, when they become useless for farming purposes there is nothing the owner can do but abandon them, and when they are abandoned they are again covered, and we can not see what else the Government could do if it owned the land than to let nature take its course, just as it does now; for to go and artificially replant such areas would, of course, be prohibitive as to cost. Doctor VAN HISE. If I might interrupt you right there The CHAIRMAN. It is no interruption. Doctor VAN HISE. So far as these lands have been deforested, and so far as they have been applied to agricultural purposes when they should not have been, there is nothing to do but to get them back to forests as rapidly as we can by the best means we can, but there are very extensive areas in the southern mountains in which that process is now going on, and which will continue, and it will continue to go on and continue to dump this great quantity of material in the streams and in the harbors if you do not stop the deforestation, which should not be permitted. We can stop that present damage if we will. Great damage, has been done. These areas have been defor- ested. There has been serious wash. These areas which never 26 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. should have been denuded of their forests ought to be restored to forests, and no more area similar to that should have the forest re- moved from it. The CHAIRMAN. In a summary of data submitted for the use of the forest section in the National Conservation Commission, as you will remember, there occurs this statement: The eastern mountain region lies east of the Prairie States, in which the planting of trees for the production of timber is of much more importance than for the production of stream flow or crops. Do you concur in that? Doctor VAN HISE. I would not concur in that for this southeast- ern part. It might be true, if that means the entire eastern part of the United States, east of the Rocky Mountains ; that might possibly be true. But as applied to this southeastern area, which is under discussion, I would dissent from it altogether. The CHAIRMAN. This statement also occurs in this same summary : The Southern States contain about 12,000,000 acres upon which natural repro- duction is insufficient or lacking, but ui>on which adequate fire protection will, In the main, restore good forest conditions And talking with citizens of North Carolina and Tennessee and, I may say, very enthusiastic advocates of this project they stated to me personally that they found it was altogether a question of fire; that if fire could be kept out of the Appalachian Mountains the slopes would never become sufficiently denuded to be a menace to the prosperity of the country. Do you agree with that statement? Doctor VAN HISE. No; not that it would altogether. If you say that the factor of fire is an extremely important one on keeping this clothing, I say yes, but that it would be alone sufficient to keep the fire out, I would not agree to it, because the removal of these areas on these slopes which have never been made into forests is another factor, and out of that factor has come this great erosion, or if not the greatest erosion a very large part of it. Therefore this can be ac- complished by a number of things. It can be accomplished by returning to forest these areas which should never have been cleared. It can be accomplished by retaining in forest those areas which are better adapted to the forest than for agricultural purposes, and those two together, combined with the prevention of fire, will solve the question. You must have the three prevention of fire, retention as torests of those areas that are better adapted to forests than to agri- culture, and restoration to forests of those areas which never ought to have been denuded of their timber. The CHAIRMAN. One more question. Do you regard the statement which has been presented here showing the high and low water sta- tistics for such rivers as of any scientific value ? Doctor VAN HISE. That general statement made by the forestry commission, of course, was a very large average statement. The CHAIRMAN. The reason I questioned the value of the statement is because it covers so brief a period. Doctor VAN HISE. It is a very general statement, but it so happens that, as to this particular southeastern problem, we have a much closer study of the Tennessee. It so happens that Mr. Leighton has given all his time for four months in studying the Tennessee particu- larly, and I have here this summary of the results. Mr. Leighton, if FOKEST LANDS FOE THE PEOTECTION OF WATEESHEDS. 27 the committee desires, can bring before you the evidence which shows the results, and in the case of the Tennessee, which I have gone over somewhat carefully, it seems to me it is a strictly scientific paper. It seems to me that the information he furnishes shows conclusively that in the past twelve years, as compared with the previous twelve years, floods have been more frequent in proportion to the number of flood-producing storms, and that is the point involved, by 18 per cent or thereabouts. This is the one stream, it so happens, upon which there has been a strictly scientific detailed study and analysis of the facts. The CHAIRMAN. The theory, of course, is that the forest cover constitutes a sort of sponge that absorbs the water, and in that way prevents flood. Doctor VAN HISE. Yes. The CHAIRMAN. Is it not true that when this forest cover, this sponge, becomes thoroughly saturated any excess water immediately runs out? Doctor VAN HISE. No; even then the excess water will gather in the needles and the leaves, and they will hold quite a lot of it. The CHAIRMAN. For instance, if I had a slate here instead of this blotting paper, any water I dropped upon it would run off imme- diately? Doctor VAN HISE. Yes. The CHAIRMAN. I take this blotting paper and drop water upon it slowly, and no water runs off. I could continue that for quite a while. But suppose, first, that I immerse the blotting paper and saturate it thoroughly, then if I drop water on it would it not run off? Doctor VAN HISE. It would run off slowly, and that is the great point. The average run-off is the same. There is no claim by us that there would not be the same average run-off if all the forest was watered, but what I say is that instead of that being made homo- geneous, so that this is a stream free from sediment, it will be a vast torrent carrying down gravel and silt at flood time, and there will be practically no stream at the other times of the year. So that this flat surface is to equalize the flow, and so make it valuable for water power more valuable for water power than for navigation, and so forth. The CHAIRMAN. I realize that an ordinary rainfall would be ab- sorbed by the humus and would be given out slowly later on, but very flood comes from an excessive rainfall ? Doctor VAN HISE. Yes. The CHAIRMAN. Otherwise there would not be any flood. When that condition occurs, when your humus is absolutely saturated, is it not true that if the rain keeps on falling there will be a flood? And is it not true that we have had floods in the rivers from time im- memorial? Is it not true in Oregon and in Washington that some of the severest floods that have ever occurred have come while the forest cover was perfect? Doctor VAN HISE. It is entirely true that if the rain is so excessive, if there is a flood-producing rain away beyond the capacity of the forest to absorb it, that even with a virghT forest we still may have a disastrous flood, although it will not be usually so ?ilt laden a flood 28 FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. as under these circumstances ; but the point I hold, and it seems to- me Mr. Leighton in his report clearly shows, is that the same number of flood-producing rains under conditions of the removal of the forests produce more floods than what would occur were the forests- kept there, and the rapidly increasing percentage, 18 per cent in the last twelve years, as compared with the previous twelve years,, due to the difference in denudation. The CHAIRMAN. Are you familiar with a paper written by Col. H. M. Chittenden and read before the American Society of Civil Engineers ? Doctor VAN HISE. No; I am not. I have heard of it, but I have never seen it. The CHAIRMAN. Colonel Chittenden has been studying this ques- tion for twenty or thirty years. Governor GUILD. If you will pardon me at this moment, Mr. Swain is very familiar with that, and if perhaps Doctor Van Hise is not familiar with it, we had better let the expert who is familiar with it answer your questions in regard to it. Mr. WEEKS. The floods are not all produced by excessive rains. In the snow regions the floods are produced by excessive melting of the snow ? Doctor VAN HISE. Yes; causing an excessive flow of water. In snow areas, where there are heavy snowfalls, that is a factor. I have not said very much about that, because it is not a very important factor in reference to these southern mountains. Mr. WEEKS. It would be a factor in the White Mountains? Doctor VAN HISE. Yes; it is a very important factor in the White- Mountains. The CHAIRMAN. Would you believe it to be true that a heavily forested watershed in a northern latitude, like New Hampshire, might give a result of more disastrous floods that an open watershed? Doctor VAN HISE. Do you mean the one that is not timbered? The CHAIRMAN. The one that is not heavily timbered. Doctor VAN HISE. I would say, as far as the facts are analyzed it bears the other way; that even where there are snow areas the number of floods is less. Although no one stream is accurately ana- lyzed in the same way that the Tennessee is analyzed, yet these tables show that the same thing has occurred, taking the evidence as a whole. The CHAIRMAN. As a matter of pure reasoning, we know that in a heavily timbered watershed the wind is broken and the snow falls practically on a level all the way through, and by the shade of the- trees it is held there a long time, until the air becomes warm. Then the warm rains come along and wash it all away at once. Doctor VAN HISE. That is comparatively rare. The CHAIRMAN. Does it not happen every winter and every spring? Doctor VAN HISE. The rain has to be a very long-continued and abundant rain. One of the greatest floods described by John Muir occurred under those conditions. That is a possibility; it is not only a possibility, but it actually occurs. But on the whole the precipita- tion in the form of snow serves to equalize* the flow. In the region of the Rocky Mountains, and also in the great valleys of California,, it is a maxim: " There is a good snowfall; we will have a good year for irrigation." FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. 29 The CHAIRMAN. That is, the unprotected slopes of mountains allow the snow to be piled in the canyons? Doctor VAN HISE. And the trees produce the same effect exactly as the canyons. Mr. WEEKS. As a matter of fact the White Mountain region is not entirely wooded ; there are open spaces and then wooded spaces. Doctor VAN HISE. Rocky spaces. Mr. WEEKS. If you are familiar with that section you know that very often the snow is entirely melted away in the open spaces when it may be a foot or two deep in the wooded spaces. Therefore if the timber or wood had been cut off in those wooded places it would have all gone off at the same time and produced much more water at one time than is produced under present conditions ? Doctor VAN HISE. Exactly. May I make one statement? I have tried to answer these questions specifically and concretely without giving their qualifications and modifications. So, in fairness to my- self, I think I ought to be permitted to make one qualifying statement. I was asked the question if I were allowed to select an area, and if I could only have one, which would I select? I said under those cir- cumstances the lower part of the steeper slopes would probably be the most important. However, I would not desire the committee to conclude therefore that I do not believe it is necessary to conserve these steep upslopes to the flat tops, because they are the' great sponge which holds this water and allows it to come down through springs and equalize the flow. That is to say, if you should remove this top area, supposing this is one of the regions, there would be destructive wash and floods here which would carry the material down. It seems to me that the only safe procedure, the only possible procedure in the Southern Appalachians, with reference to the good of the Nation, is for the Nation and the States and individuals by some system of co- operation to conserve practically all the slopes which are steeper than those which should be used for agricultural purposes. Mr. WEEKS. In the final analysis, in this last statement you have made, you would be governed by the specific conditions surrounding ach case? Doctor VAN HISE. I would be so governed precisely, if you ask me what I should do provided I had the money and could go down there and do it. In making a careful survey of all the States my idea would be to pick out the steep slopes in which there had been some .iorest removed, perhaps. I would get the headwaters of the streams, the author saw an example of this on the Scioto River near the outlet of the great Scioto swamp, which had recently been drained. A small mill was able to operate during the low-water season more regularly than formerly. Tile drain- age, now so widely used, has the same tendency. 7253S AGE 09 5 66 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. the former low-water flow of a spring or rivulet and what it is now is rela- tively an insignificant quantity. Most of such water sources yield but a small fraction of a cubic foot per second. Whether these small quantities are a trifle more or less cuts very little figure in the aggregate; and so it counts but little In the flow of a great river whether some of its extreme sources lose a portion of a volume that is already inappreciable. When the summer showers come, however, there is a marked difference. At such times the forests not only hold the water back they often swallow it completely. Small showers that make a perceptible run-off in the open are often practically all absorbed in the leaves of the trees. Heavier showers, that make freshets in the open, are largely absorbed in the leaves and forest bed and pass off in evaporation ; so that, contrary to the general view, the evaporation from the forest is greater at such times than in the open country and the run-off from summer precipitation is less. A single shower may produce a sufficiently greater run-off in a de- forested area to more than offset the diminished low-water flow for several weeks. Now, on most of the smaller streams quantity of flow is a more impor- tant matter than natural uniformity of flow, particularly in the summer time. The day of the small mill, which was so dependent upon such uniformity, is past. The modern water power invariably seeks uniformity by artificial regulation, and the ups and downs of its sources of supply are abolished in its storage. Therefore it does not matter nearly as much that the run-off of the small streams be uniform as that it yield a good flow of water ; and if forests dimin- ish the total low-water supply, this fact more than offsets the gain in uniform- ity. Likewise the great rivers swallow up and equalize the small irregularities of their headwaters and actually experience a somewhat larger low-water flow than if their watersheds were still thickly forested. Thus, while forests may decrease somewhat the extreme range between maximum and minimum run-off on very small watersheds, they do not do so on great ones, which are combi- nations of very small ones. At the same time it seems certain that forests decrease somewhat the total run-off from watersheds, small or great. 6 Influence of forests upon snow melting. The second proposition that for- ests have a beneficial effect upon the run-off from snow melting is quite as firmly fixed in the popular belief as that just considered, but has even less foundation in fact. It is a relation that can be definitely traced, and it can be demonstrated that the effect of forests upon the run-off from snow is invari- ably to increase its intensity. This results from two causes, one affecting the falling of the snow and the other its melting. In the first place, forests break the wind, prevent the formation of drifts, and distribute the snow in an even blanket over the ground. In the open coun- try, the snow is largely heaped into drifts, their size depending upon the con- figuration of the ground, the presence of wind-breaks, and the prevalence and force of the wind. These drifts form admirable reservoirs and in the high mountains are the most perfect known. Forests prevent their formation entirely. The period of snow melting begins in the open country much earlier than in the forests. At first the melting is due mainly to the direct action of the sun's rays before there is sufficient warmth in the general atmosphere to produce any effect. The thinly covered areas melt off first and the streams experience a diurnal rise and fall following the warmth of day and the frost of night. Nothing like a flood ever arises from such melting. Under forest cover this action is interfered with more or less, depending upon the density of the shade. Even after the ground in the open is entirely bare, except under the drifts, the forest areas may still be covered with an unbroken layer of snow. It is generally, though erroneously, considered that this delay Is beneficial, by carrying farther into the summer the release of the winter pre- So far as the author is aware, Col. T. P. Roberts, of Pittsburg, Pa., was the first to call attention to this characteristic of stream flow. 6 This subject was ably discussed by Mr. llaphael Zon, of the Forest Service, Department of Agriculture, in Transactions, Am. Soc. C. E. f Vol. LIX, pp. 494-495. He states, among other things, that " the quantity of water available for stream flow from forested watersheds, all other conditions being equal, Is less than from nonforested watersheds;" that "the forest soil receives least precipitation, next conies meadow land, and lastly tilled land:" that " in the forest, only the upper layer of the soil is moister than in the open, the lower layers being always drier." This discussion is well worth perusal. FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. 67 cipitation and giving it more time to soak into the ground; but in fact this benefit does not result. The water from the first melting of the snow blanket does not sink into the ground but into itself. Snow is like a sponge. A panful will shrink to one-fourth of its volume, or less, before any free water appears. The author has seen an 8-foot covering of snow dwindle to 2 feet, with the ground beneath is still comparatively dry. The forest shade thus holds the snow, which gradually becomes saturated from its own melting, until the heat and warm rains of late spring or early summer arrive, the soft air everywhere pervading the forest depths and finding a maximum exposure of surface to the melting influences. A cubic yard of snow, which in a great drift might stand 27 feet deep with a square foot of exposure, may here lie with a depth of 1 foot and 27 square feet of exposure. The result is that when the final melting begins the whole body of snow dis- appears very rapidly, rushing from every direction into the streams, swelling them to their limits and often causing disastrous freshets. The active melting lasts but a short time, and there is little opportunity for the water to soak into the ground. The delay in melting, caused by the forest shade, has simply operated to concentrate it into a shorter period and increase the intensity of the resulting freshet. It comes so fast that the greater portion of it can not be utilized at the time and is lost altogether unless intercepted by reservoirs. In the open country, on the other hand, the drifts last for weeks after the snow has entirely disappeared from the forest, and continue to yield a supply of water far into the summer. The period of active melting in the open may have lasted four mouths, that in the forest scarcely as many weeks. In the northwest corner of Wyoming and contiguous portions of the adjoining States lies an elevated region of probably 20,000 square miles, which is the source of nearly all the great river systems of the West. It is a very remarkable region in this respect. Its average altitude is about 7,500 feet, and it is in large part covered with a dense evergreen forest. At the very summit of this elevated region is that singular section now visited annually by thousands of tourists the Yellowstone Park. The opening of the tourist season in spring occurs just about the time of active snow melting, and the most onerous and difficult task of those in charge of the road system of the park is to get the roads into con- dition for the first travel. This frequently has to be done while the snow still lies deep on the ground. It was the repeated execution of this task that first drew the author's attention to the fact that, as a general rule, the floods of this region are forest floods, and that the same conditions of precipitation which force the forest streams out of their banks produce only moderate effects in the open. The traditional "June rise " comes mainly from the mountain forests. A photograph, taken about the middle of June in a year of heavy snowfall and only two days before the tourist season opened, shows an east and west road through a dense forest of lodgepole pine at an altitude of 8,200 feet. It shows very effectively the deep, even blanket of snow everywhere covering the ground, except along a narrow strip at the roots of the trees on the north side of the road, where the sun had access through the opening in the tree tops caused by the 30-foot clearing for the roadway. Another, taken practically at the same time, shows one of the great drifts in the open country, which it was impossible to avoid in locating the road. At this time a period of very warm weather had set in, with frequent rains. Severe floods followed, which did great injury to the roads and bridges, not only in the mountains, but for a considerable distance below. Within two weeks the snow had practically disappeared in the forests, but in the open country the drifts, like that in the photograph, continued until the middle of July, giving forth a continuous supply of water. A most illuminating article, and one which everyone interested in the subject should read, was published in Science for April 10, 1896. It gives the results of observations in the mountains of Nevada for over twenty-five years, during which " extensive tracts of timber " were cut off " to the very ground " and new growths had been well started. It was found that springs which were active after the land was cleared dried up when the new forest growth developed; " that the water supply from the mountains is greater and more permanent now than it was before the timber was cut off; " that freshets were no more " frequent or violent than before the trees were cut off," and that " spring floods were less frequent." The greatly increased loss due to evaporation in the forest was pointed out. This results partly from the vast extent of surface on the ground exposed to the air and partly from exposure on the leaves and branches of the trees. 68 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. " The foliage on this class of trees being as heavy in winter as in summer, the branches catch an immense amount of the falling snow and hold it up in mid-air for both sun and air to work upon; and only those who have had experience of the absorbing power of the dry mountain air can form any idea of the loss from that source." Moreover "the trees absorb from the soil quite as much water as would be evaporated by the action of the sun in the absence of the shade." The writer states that " the strongest force at work to save our rivers is the drifting winds which heap up the snow in great banks; and in this the trees are a constant obstacle." He declares that "close observers, after long yoars of study, have been led to believe that if there is any difference in the flow of streams and the size of springs before and after the trees are cut from above them, the balance is in the favor of the open country." a In the current literature upon this subject one invariably encounters the same fallacious assumption, that because the forests delay melting their action is therefore beneficial. The fact is entirely overlooked that delay means con- centration and greater intensity of run-off, while the open country prolongs the melting and gives a more even distribution. If the true action of forests in this respect, however, is rarely recognized by public writers, it is recognized, though perhaps unconsciously, by those who are benefited by it. The monthly reports of the Weather Bureau in the Rocky Mountain region are instructive reading in this connection. The following are a few extracts from those sent in to the central office of the western Montana district at. Helena : "Where there is no timber to break the force of the winds solid drifts of considerable depth have collected." * " * "The snowfall has been very light and the drifts are not large or solid enough to furnish an adequate flow of water in the streams." * * * " In some sections the winter's snowfall has been the lightest for many years, and as there is little likelihood that the later snows will form solid drifts, it is practically certain that the flow of water in most streams will be inadequate for irrigation and mining purposes." These extracts, which could be multiplied indefinitely, show how well the practical ranchman understands the value of snowdrifts. It has always been a mystery to the author that writers will persist in statements like the' follow- ing, which appears in one of the ablest addresses at the recent conservation conference in Washington: "The possibility of irrigation depends largely on the preservation of the forest cover of the mountains, which catches and holds the melting snows, and thus forms the great storage reservoirs of nature." The forests destroy the reservoirs and the flow would be more uniform, pro- longed, and plentiful if they were not there. It will doubtless be urged that while the foregoing conclusions may hold for an elevated and densely wooded region, they will not hold for a lower altitude, warmer climate, and different kind of forest. In reply it may be said that in proportion as the conditions described prevail, they apply everywhere. In deciduous forests where the foliage is absent during seasons of snowfall and melting, the winds have greater play in winter and the sunlight in spring, and there is, of course, less difference between the forests and the open country: but while the difference is less it is not obliterated altogether, and in hilly regions, like the Adirondacks and the White Mountains, it exists in full force.' The author Is very familiar with the region of western New York having been reared on a farm nearly on the divide between the waters of the Ohio and Lake Erie a beautifully wooded country, deciduous growths prevailing, and one of the snowiest regions in the United States. While there is less drifting in the open, and more in the woods than in high mountains, still it !s strictly true that the open-country drifts outlast the forest snows just as the latter outlast the thin snows in the open. The author recalls only a single other writer who has set forth this matter In accordance with the facts, and that was an anonymous correspondent in a recent issue of the Pacific Sportsman. His view of the case is summarized in rather terse language as follows: "Trees in the mountains make floods in the spring." "Snow in the timber melts too fast. The timber keeps it from drift- Ing." "The agency which maintains the river Is the snow in the huge drifts." "That (the drift) is your reservoir that feeds the living streams of summer time." " The timber has nothing to do with the water supply, but Is a result of the water supply." FOEEST LANDS FOB THE PROTECTION OF WATERSHEDS. 69 A striking example of the action of forests on snow melting may be seen in the mountains of the Pacific coast. Here are the densest forests in the world, the deepest beds of humus, and the most perfect reservoir effect so long as it is in action. Yet in this very region, particularly around Puget Sound, are to be found some of the most torrential streams in the country. This fact is largely due to the distribution of snowfall caused by the forests. Conditions like the following are constantly developing. Heavy snowstorms sweep over the forest-covered mountains. The snow can not drift, for the dense woods break the wind. A great deal of it does not reach the ground at all, but hangs on the branches and undergrowth all the way from the highest tree tops down. This covering is often so dense as to prevent cruising operations altogether, because the cruisers can not see the timber through the impenetrable screen of snow. Of an 18-inch fall, perhaps 12 inches is on the trees and the rest spread evenly on the ground. To show what now happens, let an illustration be drawn from the opposite process of drying clothes. When the housewife has finished her washing and wishes to dry the clothes, she does not set them out in a basket, where it would take weeks for them to dry, but spreads them upon the ground or hangs them on a line so that the sun and air can reach them on all sides. So these forests increase, by a thousandfold, the exposed area of the snow over what it would be if heaped in nature's clothes baskets (the great drifts), and give it the maximum possible exposure to the melting influences whenever these shall arrive. As a general rule these snowstorms are followed by warm southerly winds and rains the rains frequently heavy in themselves and rain and snow join hands, two storms in one, and rush down to the ocean in tremendous freshets and Hoods. The Skagit Iliver, the largest in Washington except the Columbia, and a very considerable stream, has been known to rise 1 foot per hour for sixteen hours, and this where the stream has a fall of 4 feet to the mile, and carries off its floods very rapidly. A photograph taken on another stream with only 480 square miles of watershed above it, shows the terrific power of these streams that come down from the most densely wooded and perfectly protected watershed in existence. The great flood of 1906 in this section was a perfect demonstration, not only of the vast intensifying effect of forests upon floods due to snow melting, but of the utter helplessness of the forest bed, when saturated with long rains, to restrain floods. The same effect was very manifest in the great flood of 1907 in the valley of the Sacrameuto River, California. The tributaries on the east side come down from the densely wooded slopes of the Sierras; those on the west side from the bare or sparsely wooded slopes of the Coast Range. If the forest theory be true, these smooth western slopes should send down a greater flow for the same pre- cipitation than the eastern slope. Exactly the reverse seems to have been the case. For the period, March 17-26, the precipitation on the Puta Creek water- shed, on the west side (805 square miles), averaged 22.7 inches. The maximum resulting run-off per second per square mile for one day was 39.1 cubic feet. Directly across the valley on the Sierra slope the precipitation, on the American River watershed (2,000 square miles), averaged 14.6 inches for the same period, and the maximum daily discharge was 48.7 cubic feet per second per square mile. Considering the fact that unit run-off for the same conditions is always less the greater the watershed, this result is quite remarkable. It is undoubt- edly due to the action of the Sierra forests on snow melting, and again illus- trates the inability of forests to exercise any restraining influence upon great floods. During the spring of 1908 occurred a record-breaking flood in western Mon- tana, nearly all the streams on both sides of the Continental Divide going far over their banks. As might have been predicted, this occurrence was promptly cited as another example of the effect that a forest-barren country has upon floods. Nevertheless it is as certain as anything of this kind can be, that if the country affected by this extraordinary downpour (in some places breaking all previous records) had been thickly forested, and the ground still covered, as it would have been, with a solid layer of saturated snow, the flood would have a In the paper, The Flood of March, 1907, in the Sacramento and San Joaquin River Basins, California, by Messrs. Clapp, Murphy, and Martin, published in x Proceedings American Society of Civil Engineers for February, 1908, the author' say : " In the Sierras the greater part of the precipitation is normally in the form of snow, and the magnitude of floods depends largely on the rate of melting. A heavy warm rain on deep, freshly fallen snow produces a maximum run-off." 70 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. far exceeded in magnitude and destructiveness that which actually took place. Wherever forests existed in the higher altitudes they did have this effect. Having now considered the influence of forests upon stream flow from a theoretical standpoint, let the records themselves be examined as far as they are available. These records in the United States, unfortunately, are not so useful as might be wished, because of their brevity. No continuous records on any of our streams run back for more than eighty years, and most of them less than half as far. This is far short of the two hundred years considered by certain European engineers who investigated Wex's theories as the minimum period " necessary in order to draw a reliable conclusion " upon this subject. It does indeed seem absurd to take present-day records, as is constantly done, and draw conclusions one way or the other as to comparisons with the past, of which records are entirely wanting ; but such as they are, a few of these records are given in Table J. They include in most cases both high and low water, although the low-water records can not, in the nature of the case, be of very much value. Works of channel improvement on most of the streams have prob- ably affected somewhat the low-water stages for the same dischai-ge, while, as is well known, a given stage, even in a natural stream, does not mean the same discharge at different times. 6 It is really the discharge of the streams rather than the stage that forms the correct basis for comparison : but data for dis- charge are almost wholly wanting. An examination of these records shows how utterly impossible it is to find anything in them to support the current theory of forest influence. They prove conclusively that there has been no marked change since the settlement of the country began, and that such change as there has been is on the side of higher high waters and lower low waters before the forests were cut off. What the record would be if we could go back two hundred years can not be said, but it may safely be conjectured that it would show both floods and low waters that would equal or surpass any modern record. It is the experience of every engi- neer who has the opportunity to observe the action and study the history of great rivers to find everywhere evidence of the occurrence of higher waters than any of which he has positive record. The upbuilding of bottom lands, the sur- vival of old water marks, and many other indications show that, great as are modern floods, those of the past were greater still. In the very nature of the case, it is not possible to find similar evidence of former low waters, because such evidence is wiped out by every succeeding high water; but whoever will take the trouble to study records of early expeditions on our rivers, when barges, keel boats, and similar craft were used, will conclude that extreme low water is not a modern development by any means. Measurements of the Monongahela River, at Brownsville, in 1838 and 1856, low-water years, gave discharges of 75 and 23 cubic feet per second, respectively. It is quite certain that the river has uot fallen so low in late years. At Pittsburg in 1S95 (the driest sesisou in recent years) it fell to 160 feet. In the Weather Bureau report, Montana section for June, 1908, it is stated that " the rainfall was phenomenally heavy over most of this district, and, com- bined with the water from the rapidly melting snow in the high mountains, caused unprecedented floods in nearly all streams." 6 During the past twenty years the low-water stage of the Mississippi at St. Paul has been materially modified by reservoir action.

It is not enough to cite a few isolated cases. In a period of, say, two hundred years, there must be a record year for high and one for low water. Is there any reason why it might not occur this year as well as earlier? There must be clear evidence of permanent change before any con- clusion can be legitimately drawn. In two instances such a tendency may possibly be claimed, the Ohio at Fittsburg and the Connecticut at Holyoke, which show, in the past few years, a greater frequency of high waters than for some years previously. To whatever extent this may be true, it is certainly not due to deforestation. The change in the forested areas on the water-sheds of either of these streams has been relatively very slight in the past twenty years. The great inroad into the timber of the upper Ohio took place many years ago. Since that time many cleared areas have grown up to timber while new areas have been cut. The change one way or the other, in recent years, compared with the total area, is altogether insignificant. The Connecticut watershed above Holyoke has a greater forested area than it had forty years ago. This is due to the abandonment of former farms which, in many instances, have grown up to timber. It is doubtful if the recent cutting in the White Mountains offsets this, and, so far as snow melting is concerned, what cutting there has been is certainly in favor of uniformity of flow. 6 In the. period of thirty-four years from 1874, the Ohio River at Pittsburg rose above 15 feet on the gauge 148 times. In the first half of this period, 68 of these freshets occurred and 80 in the second half. The mean for the first half was 19.3 feet and 20.2 feet for the second half. The mean of the lowest waters of the first half was 0.3 foot and 1.0 feet for the second half. In Transac- tions, American Society of Civil Engineers, Vol. LVIII, p. 31, is a twenty -year volumetric record of the Connecticut, which indicates somewhat higher high waters during the last half of the period. But in this case, as at Pittsburg, higher low waters are also indicated. In fact, in both cases, the greater run- off in the later period was clearly due to greater precipitation. 6 I have seen in the last few years abandoned farms (abandoned because of their unprofitableness) on the western slopes of the Allegheny Mountains, which are almost impenetrable forests of thrifty trees suitable for making mine posts and telegraph poles. There are, of course, large. areas subject to fires at intervals of a few years, but that they are subject to such recurrent fires Is FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. 75 The records of some American rivers have been given. It is, of course, in Europe that one would expect to find more definite data, because of the longer periods through which records have been kept. The histories of several of these streams have been examined without finding any confirmation whatever of the forestry theory. The floods on the river Seine, for example, show greater heights in the sixteenth century than in the nineteenth. The most exhaustive investigation of the records of European rivers, however, is that of the Danube, the great river of central Europe, recently made by Ernst Lauda, chief of the hydrographic bureau of the Austrian Government. The years 1897 and 1899 brought destructive floods to the valley of the Danube, that of 1899 being particularly severe. M. Lauda prepared an exhaustive report upon this flood, published in 1900, accompanied by elaborate maps and tables and a searching analysis of the climatic and other conditions. In his "concluding remarks," M. Lauda traces the history of the Danube floods for eight hundred years, including in all 125 floods. His conclusions are that floods were formerly just as frequent and as high as they are in recent times, and that the progressive deforestation of the country has had no effect in increasing them. In fact, the records of the flood of 1899, which was a summer flood, produced almost entirely by rain, showed that it was severest on those very parts of the water- shed that were most heavily forested. At the Tenth International Congress of Navigation, held at Milan in 1905, one of the four questions appointed for discussion was the very one here under consideration. Papers were presented by representatives from France, Ger- many, Italy, Austria, and Russia. While all the writers heartily favored forest culture, the opinion was practically unanimous that forests exert no appreciable influence upon the extremes of flow in rivers. It appears, therefore, that European experience does not support the currently accepted theory. So much for the evidence supplied by the records in this country and abroad. The constantly reiterated statement that floods are increasing in fre- quency and intensity, as compared with former times, has nothing to support it. There are, it is true, periods when floods are more frequent than at others, and hasty conclusions are always drawn at such times; but, taking the records year after year for considerable periods, no change worth considering is dis- coverable. The explanation of these periods of high water, like the one now prevailing, must, of course, be sought in precipitation. That is where floods come from, and it is very strange that those who are looking so eagerly for a cause of these floods .lump at an indirect cause and leave the direct one entirely untouched. In the records of precipitation, wherever they exist, will be found a full and complete explanation of every one of the floods that have seemed unusually frequent and severe in recent years. A few examples will be cited : The great Kaw River flood of 1903, which wrought such havoc in Kansas City, was caused by a wholly exceptional rainfall over nearly all the water- shed of that stream. In the first three weeks of May, 1903, more than the normal amount (4.5 inches) for the entire month fell. This was followed in the next five days by 3.4 inches, and upon this was piled 4.7 inches in the suc- ceeding five days, by which time the flood had crested. In the flood of 1906 in western Washington, which did enormous damage and stopped railway traffic'for upward of two weeks, the crest of the flood occurred about the 15th of the month. The month of October had been very wet, and the ground and forest storage was exhausted. In the first half of November, 25 per cent more rain fell than in the normal for the entire month, and of this about one-half came on the 13th, 14th, and 15th. In the flood season of 1905, on the watershed of the upper Mississippi, there fell in the month .of April above Pokegama Falls 2.55 inches; in M-uy, 4.95 inches ; in June, 8.03 inches, and in July, 6.88 inches ; a total of 22.41 inches. The normal for the entire year is 26.5 inches. proof of their rapid production of fuel which means twigs and leaves in great abundance. (Col. Thomas P. Roberts, Pittsburg, Pa.) The forest area in Vermont is probably 10 per cent greater than forty years ago. Of course the quality of the forest is inferior, but that has no effect on the watershed. (Arthur M. Vaughan, state forester.) Farms in the Connecticut Valley are among the richest in the State (New Hampshire) and have been less abandoned than elsewhere. There has been, however, a goodly acreage, very probably amounting to 25 per cent, which was cleared land in 1850, and which at the present time has reverted to forest, much of it excellent white-pine forest. (Philip W. Ayres, forester.) 76 FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. In the record-breaking flood of 1907 in the Sacramento Valley 88 per cent of the normal for the month of March (based on twenty-one years' observation) fell in three days (17-19), and on one day the precipitation ranged from 5 to 8 inches at the different stations. In the extraordinary flood of May and June, 1908, in western Montana, the precipitation for May," at four selected stations, was 6.5 inches and for June 4.2 inches. The greater portion of this fell late in May and early in June. The normal for May is 2.6 inches and for June 2.3 inches. Similar conditions prevail in every great flood, and the true explanation is found in them and not at all in the presence or absence of forests on the water- sheds. Whether the forests are in any way responsible for the precipitation itself and so, indirectly, for the floods, brings up the third of the foregoing general propositions, viz, that forests do increase precipitation. However strong may be the popular belief in this theory, there is nothing in the records of rainfall to give it substantial support. The author has had occasion, in connection with his official work, to compare the rainfall records in the north- ern half of the United States from the Atlantic to the Pacific, often with this particular point in mind, and he has never found anything to indicate a change. So far as he has examined European records the same result holds, and he believes it to be true the world over, except where climatic changes have re- sulted from causes entirely disconnected with the operations of man in chang- ing the face of nature. In fact, the claim that forests increase precipitation (about 10 per cent, according to Mr. Pinchot), leads to some contradictory results in the forestry argument. Coincident with our recent high waters, which are attributed so largely to deforestation, there has been an increase in precipitation, where there should, apparently, have been a decrease. It is evident that where one rule applies the other fails. So, likewise, it is held that forests are necessary to protect mountain slopes because of the greater precipitation prevailing there; yet the forests are said to increase this precipi- tation materially. There is really very little, theoretically, to support the claim that forests insure precipitation. It is said that the cooler status of forest arens condenses moisture and induces precipitation ; but if tliis were so in midsummer, when the least precpitation falls, how about the rest of the year when no such dif- ference exists, but the reverse, if anything? Take, for example, the great for- ests around the source of the Yellowstone. During the period when the bulk of the precipitation falls the temperature of the forests can not differ materially from the outside, and it is impossible to believe that the forest exercises much influence upon the snowfall. The fact that these high areas are generally wooded is frequently cited to prove that forests produce the higher rates of precipitation which also prevail there. Rut would it not be more reasonable to say that the forests flourish there because of the higher precipitation, and that the latter is due to the ele- vated situation and consequent lower temperature? Is not this, in fact, the rea- son why precipitation is nearly always greater upon the hills than upon the neighboring lowland? The mountains are nature's wine press by which she extracts from an unwilling atmosphere the elixir of life for the hillsides and the valleys below, and she does this whether the forests have been cut away or not. In one respect, and a very important one, forests diminish precipitation, and that is in the deposition of dew. Dew is essentially an open-country phenomenon, where the radiation of heat from the earth's surface is unobstructed. Clouds or high cover of any kind, and also wind, interfere with this process and prevent the dew from gathering. It collects in full strength on low -shrubbery, to a less degree on small trees, as in orchards, and penetrates for short distances under forest cover. In the heart of the native forest of full-grown timber, however, As a step in the crescendo of gloomy forebodings upon this subject, that have filled the periodicals during the past twelve months, the following from the September Scrap Book is the very latest : " When our forests are gone the streams will dry up, the rivers will cease to run, the rain will fall no more, and America will be a desert." Considering how large a percentage of our forests has already disappeared, the extraordinary rains in all parts of the United States during the past year are not exactly in line with this dismal prophecy. If one were to judge from the records of the past few years only, he must conclude that deforestation is increasing rainfall. FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. 77 dew is practically unknown. The quantity deposited in the open country in a single night is quite large under favorable conditions, leaving the effect on shrubbery and on the ground of a considerable shower. As it gathers in greater or smaller quantities on every clear, still night in the eastern sections of the country, except in the colder season of the year, the total quantity must be quite large. One authority holds that dew does not come entirely from the air, but in part from the ground. It is said that water which in the daytime passes from the ground and plants into the air is prevented from doing this at night, because the air can not receive it, and therefore it gathers in visible form on the ground and vegetation ; but if this were true, it really makes no difference in the benefit which comes from the dew. Whether the low temperature due to radiation causes a deposit of moisture from the air or prevents the air from absorbing moisture which it otherwise would, the result, so far as the ground and vegeta- tion are concerned, is practically the same. This may be as good a place as any to note one important characteristic of precipitation, and that is its tendency to move in cycles. It is well known that dry years often follow each other for long periods with great regularity, and that these are succeeded by wet periods. Take the region of the upper Missis- sippi reservoirs where the normal precipitation, based upon twenty-one years' ob- servation, is 27.1 inches; in the ten years 18SG-1895 this normal was exceeded only once; in the succeeding ten years the record fell appreciably below it only once. Omitting these two years, the mean for the two periods of nine years was 24.7 and 30 inches, respectively, an average yearly difference of nearly one- tifth of the normal. Following the well-known law that the percentage of run- off increases and diminishes with the precipitation, the disparity between the run-offs for the two periods was greater still. This phenomenon is also admirably illustrated in the rise and fall of the levels of the Great Lakes, for these immense storage reservoirs not only absorb and distribute annual variations of run-off, but equalize to a large degree the varia- tions from year to year. During the period of the eighties there wns a general rise in the lake levels, except Superior, and many people ascribed this fact to de- forestation, which allowed the water to find its way more quickly into the Lakes. During the nineties there was a period of general subsidence, occasioning con- siderable anxiety, and it was frequently asserted at that time that this was due to deforestation, which was drying up the sreams. For some years now the Lakes have been rising, Ontario being the highest in forty years; and with another wet year the levels will almost reach record heights. The long record of the Danube floods already referred to is another example. Almost invariably high floods would follow each other for several years in close succession, and then would come long intervals of ordinary high waters. These periodic changes are not, of course, due at all to the presence or absence of forests, for they occur just the same whether forest conditions remain un- changed or not. It is an order of .nature not at all understood, but nevertheless fully established as a fact. Just now we are in an era of high precipitation and consequently of high waters. There is a disposition to " view with alarm " these exaggerated conditions. Rarely does one stop to think how far better it is to the country to have these wet periods, even with all their floods, than the dry periods that will surely follow. A single dry year may cause more loss to the country through the shrinkage of crops than the floods of an entire cycle of wet years. Related to the subject of precipitation is that of evaporation as affecting the quantity of water that remains upon the ground. Generally speaking, the sur- face evaporation in summer should be greater in the open than in the forest because of the more direct action of the sun and wind : but in the height of sum- mer the forests arrest precipitation to such an extent in the leaves and humus that more of it escapes through evaporation than in the open. The effect of a The author has never seen any data as to the actual quantities of dew de- posited in different localities and conditions, and hopes that the discussion of this paper may bring some to light. He has, however, vivid recollections on the subject when, as a lad on a dairy farm, it was his unlucky lot to go bare- footed after the cows every morning without waiting to see whether the sun was going to shine or not. He knows from experience how near zero the dew point can get. and how wet dew is; and also that the warmest place in the world at such times is where a cow has lain all night, and next to that the dry precincts of the tall woods. 78 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. forests upon evaporation through the medium of their leaves finds its counter- part in the similar action of the growing crops that overspread deforested areas. As already pointed out, the forests of the mountains increase the evaporation from snow very materially. Where the balance lies among all these conflicting influences affecting precipi- tation and evaporation it is impossible to say, and when the records are ex- amined it must be admitted that they afford no answer. So far as the re- searches of science have yet determined, the presence or absence of forests cuts no figure in climatic conditions. These depend upon causes of far greater magni- tude and are influenced, if at all, only to an insignificant degree by the operations of those who occupy the planet. The fourth proposition of the forestry argument is that forests are necessary to prevent erosion on steep slopes and the consequent silting of reservoirs and watercourses below. Here again there is the same deficiency of evidence to support the theory that has characterized the three propositions already con- sidered. The author has been unable to find anything to confirm it. In his observations, embracing pretty nearly all varieties of timber laud in the northern two-thirds of the United States, he has still to see a single example where the mere cutting off of forest trees leads to an extensive erosion of the soil. Almost invariably, and it may be said always except in very unusual conditions, a soil that will sustain a heavy forest growth will immediately put forth, wjien the forest is cut down (or even burned down), a new growth, generally in part different from the first, but forming an equally effective cover to the soil. The only approach to an exception to this rule that he has observed is in some of the high mountain forests where the soil is extremely thin and weak and the action of nature in producing vegetable growth is slow. In the forest areas of the East, the growth that follows tree cutting consising not only of new trees, but of briars and small brush of every description accumulates very rapidly and forms a more effective mat against erosion than the original forest itself and equally effective in storing water. Such low growths have also a better effect upon snow melting, because they give both wind and sun freer play. Certainly the ground in a forest under culture, with the debris raked up, is more easily eroded than that of a slashing or second-growth area, or even good meadow or pasture. A forest soil unprotected by forest debris is almost as erosible as a field under culture. The increased erosion of the soil, of which so much is heard, does not result from forest cutting, but from cultivation, using that term in its broad sense to include all of man's operations for the occupancy and utilization of the ground from which the forests have been removed. It is the " breaking of the soil " that leads to its erosion by the elements. Roads and trails are one of the great sources of erosion in hilly countries, but plowing and tilling are the principal causes. The question is not one of forests in the first instance, but of how far the cultivation and occupancy of the soil can be dispensed with. Even on steep mountain slopes, where erosion and ruin have resulted, the effect is often due to the clumsy and injudicious work of the husbandman who uses no judgment of cause and effect in the way he exposes the soil to the force of the storms. The successful cultivation of hillsides in every quarter of the globe is an everlasting refutation of the argument that forests are necessary to protect the face of the earth wherever cultivation is practicable. Some classes of cultivated vegetation, like the well-knit turf of meadow or pasture, are a better protection against erosion thau any ordinary forest cover. That there are sections of the country where erosion of the soil is much more rapid than in others under similar conditions is perfectly true. This is especially the case with certain districts in the Southern States, and very likely forest protection is there better than any other; but it is still true that the problem of control of soil erosion on cleared lauds is essentially a problem in cultivation. It is not so much the absence of the forest as it is the cutting of roads and ditches, the upturning of the soil, and the various kindred operations of man that quicken the run-off and increase the surface soil wash. The oft-repeated assertion that, owing to the cutting off of forests, our rivers are shoaling up more than formerly may be challenged absolutely. There is nothing in our river history to support it except in a few instances, like the Yuba Kiver in California, where extensive hydraulic or similar operations have produced vast changes. It is exceedingly doubtful if it can be established by any evidence worthy of the name that the streams of the Mississippi basin are more obstructed by sand bars than formerly. The author's observation of FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. 79 upward of twenty years and inquiries from many sources fail to disclose any such evidence. It would not, indeed, be surprising if some such result were noticeable, for it would naturally seem that the cultivation of the soil has facilitated to some degree the wash into the streams. If this is the case, however, the rivers do not show it. They have a way of distributing their burdens so as to meet their necessities and, except in rare cases, they do not shoal appreciably more than formerly.^ The distinction between erosion actually resulting from cultivation and that assumed to result from timber cutting is important to keep in mind, for it fixes the burden of responsibility where it belongs. It shows that this erosion or soil wash can be reduced only by the elimination or control of cultivation, and the question at once becomes that of the extent to which such control or elimination is practicable. For example, it is insisted that the suggested reser- voir system of the Ohio, to be referred to later on, will be absolutely dependent for its integrity and permanence upon keeping the watersheds above them covered with forests. But it is understood not to be the policy to include in the proposed forest reserves any lands that are fitted for agriculture. 6 As elsewhere pointed out, that portion of these areas which is not reduced to cultivation will not be subject to erosion more than at present by the mere fact of cutting off the timber, for the natural growth on logged-off lands is just as good a protection as the forests themselves. If the agricultural tracts are still to be left open for occupancy, the source of sediment remains uncurbed and the whole argument for forest reserves, on the ground of protecting the reservoirs from sedimentation, falls to the ground. Some reference should be made to the real significance of- the alarming re- ports which have been put forth concerning the washing of our soils into the sea. Over and over during the past year has the statement appeared that 1,000,000,000 tons of our soil is annually carried by our rivers into the ocean. This figure itself is quite conservative, but the conclusions drawn from it are not at all so. Taking the results of silt observations on the Mississippi River and its tributaries for 1879 and applying the Missouri rate to all western streams outside the Mississippi basin and the Ohio rate to all eastern streams outside the same basin, a total of about 1,100,000,000 tons is indicated. But 1879 was a low-water year in the Mississippi basin and the quantity for average years may probably be 1,500,000,000 tons and for extreme years 2,000,000,000 tons. Let us look these prodigious quantities squarely in the face and see what they mean. Where does this enormous volume of soil come from? Is it, as one might infer from published references to the subject from our cultivated fields an annual toll laid upon the precious fertility of our agricultural lands? Not at all. Only a very small proportion comes from this source. Possibly half of the total quantity of sediment goes down by the Mississippi. All authorities agree that the greater portion of this comes from the Missouri. From computations which the author has nfade he believes that fully two- thirds of it conies from that source. The observations of 3879 indicate that five times as much sediment comes from that stream as from the Ohio. But where does the Missouri get it? Almost entirely from the most useless areas of land with which any country was ever afflicted. The barren Bad Lands are the principal source. Much comes from the mountains; much from the sand hills; very little, relatively, from cultivated areas. Of the balance of the soil wash of the United States, by far the greater portion comes from The absurd length to which this erosion argument has been carried is well illustrated by the remark made in a recent address by one of the officials of the Forestry Service: " This energy (of running water) is expended in rolling along stones and gravel to finally build up the mouths or beds of the great rivers. Next year there will be a bill introduced in Congress providing a forest reserve in the Appalachian Mountains, so that the rocks from these mountains will be kept from the Mississippi River!" 6 Among references to the intention not to absorb agricultural lands in the areas conserved by the reservoirs is the following from A. F. Horton, Assoc. M. Am. Soc. C. E., in Engineering News, June 11, 1908: "The reader should not lose sight of the fact that the conserved area is not rendered unfit for cultiva- tion or other use, but that only a small portion of the conserved area (that covered by the reservoir) is so utilized that its value for cultivation is de- stroyed." 80 FOEEST LANDS FOB THE PROTECTION OF WATERSHEDS. other similar sections of the West, where the streams carry enormous loads of sediment. The entire Colorado system is even more distinguished in this respect than is the Missouri. The same is true of the Kio Grande, the Pecos, and the upper courses of the Arkansas and lied. Even the streams of the Great Interior Basin are heavy silt hearers, and the same is true of many of the streams of the Pacific coast. The streams flowing into Puget Sound are heavily laden with silt at certain portions of the year, and the great Columbia bar is impressive evidence of the vast burden of sediment which that mighty river has carried to the sea. Nearly all of the annual load carried by these streams is entirely unaffected by anything which man has done. It is the regular natural carving down of the hills and building up of the valleys and estuaries below. The eastern streams are clear and sediment-free compared with those of the West; but even in these a large portion of their sediment is eroded from the gorges and canyons of the hills and mountains, which will continue to wash away as long as the rivers flow. This particular class of erosion, on both eastern and western rivers, is far less objectionable than one is led in these later days to believe. Has it not from the beginning been one of the most beneficent operations of nature? Are not the richest lands in the world the river bottoms and deltas built up in this wayV To a very great extent the irrigated lands of the West are composed entirely of the debris from the mountains and the bad lands. Even to-day this tribute from the highlands is of great value. The periodic enrichment of the Ohio bottom lands and similar tracts in hundreds of other places is of the highest economic impor- tance. The soil-laden waters of irrigation in -the spring, though sometimes injurious to the growing crop for the time being, are on the whole extremely beneficial. The damage from sediment is not in its injury to the lands ordina- rily, but to ditches, canals, reservoirs, and similar works. On the whole it is, and always has been, a benefit to the lowlands. Even that portion carried out to sea builds up deltas and surely, though slowly, extends the habitable area of the globe. IS'ot alone in the resources of water and timber, but, in the perpetual renewal of soil as well, has the valley said to the mountains throughout the world's history: "I will lift up mine eyes unto the hills from whence cometh my help." Sediment of this character, except when accompanied by alkaline salts or other similar ingredients, is not injurious to domestic supply. The water of the Missouri Itiver is one of the healthiest drinking waters in the world in spite of the fact that it rs one of the muddiest." The proportion of soil wash that comes from cultivated fields is really very small compared with the enormous total that the rivers carry away. Heavy rains undoubtedly wash farm soils a great deal, but this erosion is in large part a transfer from one spot to another and not an absolute loss. The history of the old Ohio Canal reservoirs indicates very little filling in the sixty-six years that they have been In existence. According to the chief engineer of the Ohio state board of public works. It is scarcely appreciable in some of the reservoirs, and in none does it amount to as much as inches, or one two-huudredths of an inch per year from the tributary watershed. Yet these reservoirs are sur- rounded by rich agricultural lands. The silt observations on the Ohio in 1S79 indicate only a little more than one six -hundred ths of au inch over the entire watershed; but this, it is true, was a year of light rains. It Is readily seen that the formidable danger of which so much has been written of late becomes quite harmless as to quantity when it comes down to the Individual farm. The harm is probably not so much in the quantity of soil actually lost as in the fact that the soil may be leeched of some of its more important ingredients. The evil is one which can be controlled only by better methods of farming, whereby the surface waters will be restrained from eroding the soil; but even these measures have their adverse side, for when heavy rains prevail for a long time it is more important to the farmer to get the water off bis land than it is to save a little soil. Most of the soil will stop on lower ground and not be wholly lost, but if the water is not gotten rid of the crop niav be ruined. The late J. B. Johnson, M. Am. Soc. C. E., used to say, in extolling the vir- tues of Missouri Kiver water, that it was the most perfectly filtered water in the world; with this difference, however, that in the ordinary case water is run through the filter, but here the filter is run through the water. FOBEST LANDS FOE THE PROTECTION OF WATERSHEDS. 81 The caving of the banks of our great rivers is constantly cited as an example of soil loss on an enormous scale, and it is asserted that this condition is worse now than formerly. The Mississippi and Missouri rivers, practically alike in this respect, are the two most prominent examples. The author will consider briefly the case of the Missouri because he has had a long and intimate acquaint- ance with that stream from its mouth to its source. It may be stated by way of refutation that the actual condition of this stream to-day is better thau before settlement began in its valley, except that possibly the low-water flow is slightly diminished to meet the demands for irrigation. The stream is not "constantly becoming more and more savage," as a recent writer asserts. On the other hand, its natural savagery is much restrained. Probably 100 miles of its banks are protected ; snags and drift heaps are largely removed; considerable bottom land has been reclaimed and turned to indus- trial use; floods are no greater than they used to be, and navigation is safer and easier. Navigation has ceased, not because the river has deteriorated, as is commonly asserted, but because the natural difficulties peculiar to this stream are so great and so hard to overcome that boats can not live and do business -at the same rates at which railroads transport freight. That the river is a most destructive one to the bottom lands along its course is only too true; but the character of its destructive work is generally misun- derstood. The writer just quoted states that the river carries away annually 8,000 acres of bottom land within the limits of the State of Missouri alone. The total acreage of these lands is about 640,000. If this statement were true, more than the entire area would have been carried away since the voyage of Lewis and Clark, and if the process had been continuous since Columbus dis- covered America the river to-day would be flowing in its original channel in the solid rock, 75 to 90 feet below the present surface. As a matter of fact, there is more soil in the valley to-day than there was at the date of either of these 'events. Taking an average for a considerable period, none of the bottom land is lost. It has always been slowly rising through accretion. The bank caving is only a transfer from one point of the shore to another. For every dissolving bank there is a nascent bar. Where steamboats ran last year wil- lows may be growing this, and next year the farmer may be planting his corn. The havoc wrought concerns the individual owner, but not the valley bottom itself. The cruel losses attract attention ; the unobtrusive gains do not ; but the account always balances itself. The' harm done is first to the individual whose possessions are swept away, and second to the community through paralysis of development, depreciation of values, and the holding back of this natural garden spot from becoming what it ought to be. The evil is a very real one, and the author has long endeavored, though without success, to secure provision in the river and harbor bill for its amelioration. Great as the evil is, however, it is not at all in the nature of an actual loss of land to the valley. It must be clear from the foregoing that the bottom lands of the Missouri add nothing whatever to the total quantity of sediment that passes out of the mouth of the stream, for these bottoms have been increasing rather than diminishing in quantity. Likewise, the Mississippi bottoms contribute nothing to the volume of sediment that is carried into the Gulf of Mexico. It all comes from the uplands, far and near, but principally from the more remote and hilly regions. This load is in the nature of through traffic. The local freight picked up from a caving bank is mostly discharged at the next station. It follows, therefore, that if the banks of these streams were revetted from the Gulf to Pittsburg, the Falls of St. Anthony, and the mouth of the Yellowstone, the quantity of sedi- ment passing into the Gulf would not be diminished a particle. Such revetment would nevertheless be of the very highest value, if it could be made to hold, for it would give permanence to the banks, security to riparian property, and would largely prevent bar building by training the river into a regular channel and relieving it of everything except its through load of sediment. The bank-caving problem of these valleys is unaffected in any appreciable degree by the influence of forests or culnvation on the watersheds, and can not be solved or materially assisted by any practicable changes in these conditions. The problem is strictly a local one, and the remedy must be a local one. Even if it were possible to bring the waters down from the uplands perfectly clear, it is not at all certain that the effect upon the bottom lands would not be injurious rather than beneficial ; for then the caving soil, instead of being quickly depos- Transactions American Society of Civil Engineers, Vol. LIV, p. 336. 72538 AGB 09 6 82 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. ited again, would in part be carried out to sea, and the bottom lands, unless protected, would be gradually eaten away. In addition to the four main propositions discussed above, a few subordinate features of the question will now be considered. A feature of the Forestry Service which is generally overlooked is the possible effect of culture upon the bed of humus, so much relied upon in these discussions to prove the restraining action of forests upon run-off. Mr. Piuchot, in his statement to the Judiciary Committee, said : " The effect of a forest on a steep slope is to cover that slope with leaves, rotten and half rotten sticks, and other mechanical obstructions, which prevent the water from running below as rapidly as it would otherwise." It is understood that the forest policy is to keep this litter cleared up as a measure of fire protection, and one frequently sees in articles on forestry photo- graphs of the typical forest culture in which the ground is thoroughly cleaned up. The result must be to diminish proportionately the retentive action of the forest bed and to increase its liability to erosion. In the light of the foregoing discussion fire protection is of much greater importance than the retentive effect of the forest bed on the run-off. The remarkable degree to which the forest bed will dry out in prolonged drought, making it one vast tinder box, supports this conclusion, and is another proof of the extreme desiccating effect of forest growth upon the soil. It often escapes attention, except with those who are in the woods a great deal, that the water establishes little channels through the debris where the latter is of long accumulation and somewhat permanent in character. Such debris does not in reality offer so great an obstruction to flow as one would suppose, and as would be the case if its condition underwent frequent change. The statement is constantly met that forests are very efficacious in the pro- tection of river banks from undermining and steep slopes from sliding. . The exact reverse is the case. As every river engineer knows nothing is more disas- trous to a river bank on an alluvial stream than heavy trees. This is due partly to the great weight, but in large part to the swaying effect- of the wind and the enormous leverage of the long trunks which pry up the ground and facilitate the tendency to undermining. One of the regular policies of river control is to cut down these trees for a distance back from the edge of the bank wherever complications with private ownership do not prevent. Snags and driftwood in the channels have always been among the most serious obstacles to navigation on streams flowing between forest-covered banks. Likewise where railroad or highway grading cuts the skin of unstable mountain slopes, the presence of large trees immediately above tends powerfully to loosen the ground and cause it to slide ; and in such cases it is necessary to cut down the timber. Far better than forest trees on river banks are thick growths of willow, alder, or any of the smn Her close-growing shrubs; and on side hill slopes either such shrubbery or a good turf. In the current discussion a great deal is made of the fact that mountain slopes are "quick spilling," the deduction being that they therefore are more productive of floods. This is quite contrary to the fact. It is perfectly true that more rain falls on the hills than on the lowlands, that a greater percentage of rainfall runs off from steep than from flat slopes, and that it runs off more rapidly; but it does not follow at all that these conditions produce greater floods. A mountain stream carries off the water within its banks a great deal faster and more safely than a similar stream in the lowlands. The banks are almost always stable and the bottoms rocky or composed of heavy gravel or lowlders; in fact, floods do less harm on such streams than on any others. In the lowland, where the streams have smaller slopes and unstable banks, much smaller run-off produces greater floods and more destruction. Moreover; nature to a large degree adapts streams to the work required of them. The channels The following testimony before the JJoard of Consulting Engineers, Panama Canal, is to the point (Report, p. 329) : Question by Mr. Welcker : Mr. Chairman, I would like to ask if Mr. Dauchy thinks that vegetation prevents the sliding? Mr. DAUCHY. My experience has been the reverse ; I have stopped sliding hills by cutting off the vegetation. The weight of the timber on a sliding slope aids materially to assist the sliding. Mr. WELCKER. Does not the vegetation diminish it? Mr. DAUCHY. If you could get a grass-covered slope it would help to diminish it. FOKEST LANDS FOB THE PROTECTION OF WATERSHEDS. 83 of the tributaries of the Ohio have been carved out through long ages to carry in safety the average flood flow. Area for area of watershed, their cross-sections are much larger than those of streams in climates of less rainfall. The normal section of the Ohio at Wheeling is over 2 square feet for every square mile of watershed, while that of the Kaw River at Kansas City is less than one-third square foot per square mile. It is therefore wholly erroneous to conclude that the streams of these mountains are more subject to over-bank freshets than those of the lowlands or that the freshets themselves are more destructive. Considering the conditions growing out of settlement the reverse is unquestion- ably the case. ' There is one other consideration of prime importance in this forestry argu- ment, and that is the fact that no possible development of forestry can increase the present percentage of forest-covered areas. At least as much ground as is now devoted to agricultural purposes must continue to be so used. The utmost admissible expansion of national forests will never require a greater area than is now occupied by forests and second growth or logged-off lauds, which, so far as run-off and erosion are concerned, are just as effective as the virgin forest itself, and more effective than will be the groomed forest of the. new regime. There may be a shifting of areas devoted to forests, but possible expansion, compared with the present area, is so small that its influence upon the great rivers, even admitting the full force of the forestry argument, would be wholly inappreciable. The fact just dwelt upon should make us thankful that the forestry theory as to the stream flow is not correct. Whatever the value of forests we can not have them everywhere, and by far the greater portions already cleared away must always remain deforested. If this fact of deforestation has brought with it in greater degree than of old the calamities of high and low waters, then, indeed, we are in an unfortunate case. But it has not done so. Nature has decreed no such penalty for the subjugation of the wilderness, and on the whole these natural visitations are less frequent and less extensive than they were before the white man cut away the forests. In summarizing below the foregoing argument, the author would be particu- larly careful to guard against sweeping assertions in any of his conclusions. He well understands how little the subject is capable of precise demonstration. Snow, for example, does not always fall, even in the open country, under the influence of the wind, or it may fall in a wet condition that keeps it from drifting. Altitude comes in with its lower temperature and modifies the general result. There is a vast difference between a northern and a southern exposure even with the same slope and topographical conditions. Precipitation scarcely ever occurs twice alike on the same watershed. The combination of flow from tributaries is never the same in any two floods, and there is an endless variety of conditions that must qualify our rules and make us cautious in making claims in a matter of this kind. The author objects solely to the contrary course pursued by many forestry advocates to the extreme claims that forests exert a regulating influence upon stream flow in times of great floods or extreme low water in our larger rivers. These claims stand to-day absolutely uuproven. The difference _between past and present conditions is not great. One influence offsets another with such nicety that the change, if there is any, is hard to find. The " delicate balance " maintained by nature where man has not cut away the forests is replaced by other balances equally delicate and efficacious in the drainage of lands, the growing of crops, and the deposition of dew. In the following seven propositions the author sums up the arguments pre- sented in the foregoing pages: (1) The bed of humus and debris that develops under forest cover retains precipitation during the summer season, or moderately dry periods at any time of the year, more effectively than do the soil and crops of deforested areas similarly situated. It acts as a reservoir moderating the run-off from showers and mitigating the severity of freshets, and promotes uniformity of flow at such periods. (2) The above action fails altogether in periods of prolonged and heavy precipitation, which alone produce great general floods. At such times the forest bed becomes thoroughly saturated, and water falling upon it flows off as readily as from the bare soil. Moreover, the forest storage, not being under control, flows out in swollen streams, and may, and often does, bring the ac- cumulated waters of a series of storms in one part of the watershed upon those of another which may occur several days later ; so that, not only does the forest 84 FOBEST LANDS FOB THE PEOTECTION OF WATEBSHEDS. at such times exert no restraining effect upon floods, but, by virtue of its un- controlled reservoir action, may actually intensify them. (3) In periods of extreme summer heat forests operate to dimmish the run-off, because they absorb almost completely and give off in evaporation ordinary showers which, in the open country, produce a considerable temporary increase in the streams; and therefore, while small springs and rivulets may dry up more than formerly, this is not true of the larger rivers. (4) The effect of forests upon the run-off resulting from snow melting is to concentrate it into brief periods and thereby increase the severity of freshets. This results (a) from the prevention of the formation of drifts, and (&) from the prevention of snow melting by sun action in the spring, and the retention of the snow blanket until the arrival of hot weather. (5) Soil erosion does not result from forest cutting in itself, but from cultiva- tion, using that term in a broad sense. The question of preventing such erosion or soil wash is altogether one of dispensing with cultivation or properly controlling it The natural growth which always follows the destruction of a forest is fully as effective in preventing erosion, and even in retaining run-off, as the natural forest. (6) As a general proposition climate, and particularly precipitation, have not been appreciably modified by the progress of settlement and the consequent clearing of land, and there is no sufficient reason, theoretically, why such a result should ensue. (7) The percentage of annual run-off to rainfall has been slightly increased by deforestation and cultivation. If the foregoing propositions are correct they enforce two very important conclusions one relating to the regulation of our rivers and the other to forestry. It follows that no aid is to be expected in the control or utilization of our rivers, either for flood prevention, navigation, or water power, by any prac- ticable application of forestry. Remember always that it is the extreme of flow, not the medium condition, that controls the cost of river regulation. It is the floods and low waters that measure the cost. Any scheme of control that is not based upon these Is worthless. This proposition need scarcely be urged upon the experienced engineer. For himself he would never place any real reliance upon forestry. Called in consultation, for example, in the problem of protecting the city of Pittsburg from floods, he would be bound to take as his measure of the problem the highest recorded flood on the river with a good factor of safety on that, and then figure out by what methods artificial reservoirs, levees, raising of grades, or clearing the river channel of artificial obstructions he would obtain the desired relief. He would not dare, as the physician in the case, to advise his patient that he could dispense with or lessen in any degree the application of the remedies proposed, nor save one dollar of the cost, by anything that might be done in reforesting the watershed' of the rivers themselves. In like manner no engineer could honestly advise lowering in height by a single inch the levees of the Mississippi, because of any possible application of forestry to the watershed of that stream. And again he could not advise that forestry development would lessen in any degree the cost of improving the rivers for low-water navigation. Engineers fully understand their responsibility in these matters. But great engineering projects can not be carried out without money, and the people will not give the money unless convinced of the necessity and wisdom of the plan proposed. So long as there is apparently some easier and simpler plan, some panacea, no matter how nebulous or unproven, that offers a way out without the expenditure of so much cold cash, they will be backward in voting money, and the counsel of the engineer will be of no avail, Possibly the author is too positive in this opinion. He finds that, in one case at least, the city of Williamsport, Pa., reputable engineers have advised refor- estation of mountain slopes as a protection against floods. The statement of " an eminent authority " was cited with approval to the effect that " four-fifths of the precipitation is detained by the surface of the ground" under forest Cftver. But here, as in all these assumptions, the rule applies only to the average condition. The point is overlooked that in periods of heavy precipita- tion the retentive capacity of the forest bed becomes exhausted. If the city of Williamsport is relying upon this advice it is certainly laying up for itself a season of repentance. FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 85 Hence the complete divorcement of forestry from any connection with river regulation so far, at least, as its effect upon the cost of such regulation is con- cerned will be a distinct and positive gain to the latter. In the second place, forestry will be left to work out its own salvation without any reference to the rivers. Will not its cause be promoted by this divorce- ment? At first thought it may seem that thereby one great argument for for- estry is lost ; but no argument can be of value in the long run that is not based upon truth, and the disappointment that is certain to result in the fulfill- ment of these hopes will do more harm than good. Forestry does not need any such support. It stands on a basis of its own, too broad and too sure to require any extraneous aid. What is this basis? The reply may be given in the beau- tifully appropriate phrase that occurs in the act of Congress creating the first of our national parks, " the benefit and enjoyment of the people." In the matter of benefits, forests are necessary, because they produce the most important material of construction known to man ; even iron can not be excepted. From the lead pencil to the mast of a ship, from the infant's top to spacious temples and palaces, it enters into nearly every requirement of human existence. A large portion of the structures for human habitation are built of it. The land transportation of the world is closely dependent upon it, for if it were not for the railroad tie scarcely a car could run. It is only when one stops to think a little upon the unlimited adaptability of wood to human needs that its trans- cendant importance is borne in upon him. In the matter of enjoyment, no other work of nature has done more for the uplifting and ennobling of the mind than these " first temples " of God. It requires no argument to enforce this assertion, particularly with him who has been reared in close companionship with the woods. Sad, indeed, will be the day, if it ever comes, when the people are deprived of this source of healthful pleasure for which no adequate substitute can ever be found. And yet this supremely important resource in human happiness is strictly limited, and the visible supply is fast disappearing. Statistics fix the date, almost as confidently as an astronomer predicts an eclipse, when the doomsday of its 'final disappearance will come unless something is done to prevent. Most fortunately this material, unlike copper or iron or stone, is a vegetable product capable of self-renewal, and the supply can be kept up forever. This is what gives it extreme importance to forestry. It requires no dubious support from any other source. It fully justifies the splendid work that the Forestry Service is doing and demonstrates the wisdom of the farsighted men who are laying the foundation of our future national forests. Let us now inquire if it will not be to the advantage of this great work to be absolutely independent of any connection with waterway development. Will it not be better in every way for forestry if it is promoted solely on the basis of producing trees for human use and enjoyment, and not at all for any supposed influence upon flow of streams? Is it really a wise move, so far as forestry is concerned, to single out the rugged and inaccessible mountains as localities where our future supply of timber must come from? The availability of for- ests to human needs depends very largely upon the situation in which they grow. Few people understand the exceeding importance of this matter. The converting of a forest tree into form for use involves two distinct processes, the conversion of the tree into lumber or other product and its transportation to the place of consumption. The cost of logging operations is immensely increased by the roughness of the ground. In our western forests, for example, it requires a higher grade of skill, commanding higher wages, to " lay " a tree on a steep hill- side than on even ground. The losses from breakage in falling are much higher, and the difficulty and expense of getting the logs out much greater. In fa'ct, the increase of cost runs all the way from $1 to $10 per 1,000, depending upon the situation. Engineering News stated the case very forcibly in regard to the Appalachian forests (though it did not have this particular thought in mind) when it said, in a recent issue, that " the cutting off of forests on the remote mountain slopes has only become possible with the high price of lumber that has prevailed for ten years past." This increase of cost represents the perpetual tax that the public must pay for timber from these regions as compared with that from the lowlands. And a great deal of it can never be gotten out at all. The poet's " gem of purest ray serene " was not more lost to human needs than are tens of thousands of noble trees in the rugged fastnesses of our mountains, east and west. Benefit? To convert them into lumber will cost more than they are worth. Enjoyment? Only the solitary hunter or mountaineer ever sees them. These are not the places to rear up forests for the good of the people. 86 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. Consider the question of transportation and take Chicago as being practically on the meridian through the center of population of the country. The rate on fir from the Cascades to Chicago is 55 cents per 100. or $16.50 per 1,000 feet h. in. The average rate from the Appalachian forests is about 18 cents, or about $9 per 1.000 for green oak. By a proper distribution of our forests these rates on the average ought to be brought within 10 cents per 100. In logging nnd transportation together, the country will tax itself on the average not less than $10 per 1 000 for whatever supply it derives from these mountain forests as compared with what it might receive from forests more favorably located. If it were not for the erroneous assumption that forests have a regulative effect upon the flow of our navigable rivers, would not the policy in regard to the acquisition of hinds for forest reserves be quite different from that now proposed? If Congress were to vote, say, $10,000,000 at the next session to commence the establishment of national forests by purchase, would it not be far better spent in lands where the pine, oak, cherry, and ash used to grow, in locations convenient for access by the people and in every way better adapted to their needs? States, counties, or other agencies should be required to meet half the original cost. Even if the total cost to the Government were several times what equal areas in the mountains cost, it would be far more economical in the long run. There is an abundance of land in nearly all the States, suit- able for the purpose, that can be had at not excessive cost. In New England, for example, would not the development of forests in the lowlands, where in many places former cultivation has been abandoned, be far better than to buy up the difficult slopes of the White Mountains? Let there be a national forest in every county of the United States where it is practicable to create one. Let its location be carefully chosen so that its product may be manufactured and shipped with the smallest cost to the people, and serving also not only as a pleasure ground but as a stimulus to similar work by .private agencies. It will be urged that these mountain lands are worth more for forestry than for agriculture. Very true; but that would not justify their purchase if the same money would produce a better result elsewhere. " Never buy wh,at you do not want because it is cheap." Again, it may be said that here is our only remaining timber supply in the East, and it must be saved. Except in some possible economy by the more judicious cutting under government control, it is not apparent how a forest tree that has attained its growth is going to render any greater good to humanity by being saved for the next generation than by being cut for this. There is a general sentiment current in these later years that if timber is cut off by private agencies it is wasted; but does it not find Its way into common use just the same? Not as completely, perhaps, but still substantially the same. Take the combination of the Weyerhaeuser Timber Com- pany, considered entirely apart from its economic and ethical aspects as a great trust or corporation, and solely as a preserver of our forests. With its system of fire control, its policy of holding its timber for high prices, is it not really conserving the timber for future use? To speak of such timber as being '' lost" to the people, " wasted," and its acquisition as a " looting of our heritage," is as disingenuous as it is untrue. Will its lumber cost the consumer a cent more per thousand than if it were from a government reserve? It is a wholly gratui- tous assumption that our timber is going to be " wasted " unless it is ^placed under government control. The thing of prime importance is to get new forests started. In the thirty to fifty years that our present supply will last new for- ests should be brought into existence all over the country. This is far more important than to buy the virgin timber of the Appalachians. Moreover, it seems now to be considered that the virgin lands have already risen too high in price to be purchased by the Government, and that it is only the second-growth lands that can be economically acquired. Be that as it may, It is certain that the acquisition of such of these lands as are desirable for the strict purposes of timber production will be greatly facilitated by disabusing the minds of the owners of the impression so diligently fostered of late that the very salvation of the country depends upon their selling out to the Government. Can anyone doubt that the present course will add vastly to the purchase price? Still another argument that may be urged is that only by linking the forests with the rivers in a way to establish their utility in maintaining navigation can the constitutional objection to the acquisition of these lands be overcome. But Report of Secretary of Agriculture on Southern Appalachian and White Mountain watershed, December, 1907, pp. 8, 30, 35. FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. 87 does this apply to mountain forests more than to any others? It is incontest- ably true that whatever restraining effect forests have upon run-off is greater upon the lowlands than upon steep mountain sides. This legal feature of the question will be referred to further on. EESERVOIBS IN THEIR RELATION TO STREAM FLOW. Under this heading artificial reservoirs alone are included. Natural reser- voirs of various kinds exist nearly everywhere and exert a profound influence upon stream flow. The ground is the most important of these, absorbing on the average probably one-third of the total rainfall. Natural lakes are great regu- lators, the St. Lawrence system being the most perfect example. Forests are effective reservoirs at certain seasons. Swamps and low-lying grounds along river courses, like the great flood basins of the Sacramento and the Mississippi, are, in their natural state, enormous reservoirs which greatly reduce the flood flow of the river channels. Snowdrifts, particularly the great drifts of the mountains, are splendid reservoirs. The streams themselves have immense storage capacity ; for example, the Mississippi within levees stores at least 2,000,000,000,000 cubic feet of water from Cairo to the Gulf, between extreme high and low water stages. All these reservoirs and many of less importance are ever active in regulating the flow of streams. Without them precipitation would flow off as fast as it arrives and our greatest floods would be magnified many times. Here we are considering only those reservoirs constructed by man to sup- plement and extend the regulating effect of nature's reservoirs. If the conclu- sions reached in the first section of this paper are correct, forests can not be relied upon in any degree to help solve the problems of high and low water. Present conditions must be met by purely artificial means, since man has so far discovered no way of controlling the climatic conditions which govern precipita- tion. He can not " stay the bottles of heaven " in times of flood, nor open them in seasons of drought. He must take the water after it reaches the earth and deal with it the best he can. The artificial reservoir is intended to attack this problem at its source. It catches and holds back the water in the near vicinity of its deposition, instead of waiting until it gathers into the rivers and then building huge bulwarks to contain it there in times of flood. It saves the stored-up supply and gives it out in the low-water season, thereby helping navigation, instead of dredging and otherwise treating the water courses to increase the low-water depth. It cor- rects one of the greatest deficiencies of nature by abolishing inequalities of stream flow and converting waste into utility. Theoretically, it is the perfect plan. It has always appealed to the imagination of laymen and professional alike. It has often been resorted to, and the number of reservoirs in the world is very great and constantly increasing. Hitherto they have been mainly used for power, municipal supply, irrigation, and for navigation in canals. In very few instances have they been applied to improve the navigation of large natural water courses, and in none, so far as the author is aware, for the exclusive pur- pose of preventing floods. The question arises, AVhy are they not regularly applied to these last- mentioned purposes? The answer may at once be given that in the general case the cost is greater than the benefits to be received. This element of cost arises mainly from the absence of good sites (including dam sites as well as holding basins) and also, to considerable extent, from an interference with the purely artificial conditions growing out of the settlement of the country. The best reservoir site is a natural lake. Such a site is already covered with water, and original conditions are not materially changed. Evaporation is not much increased by the necessary enlargement. Smaller and safer dams accom- plish a given storage than for the average dry site. The question of public health involved in uncovering large areas for reservoir beds in the heated por- tion of the year is less serious. Everything makes these sites the most advan- tageous that can be found, and it may be laid down as a rule that the public good requires the utilization of every such site to the fullest possible extent. An interesting feature of these natural reservoirs may be noted. A natural lake, wholly uncontrolled at its outlet, may have a more effective control of the outflow than an artificial reservoir of equal superficial area when full, though of far greater capacity between high and low water. The outflow from a lake can be increased only by storing simultaneously a quantity of water measured 88 FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. Except in a few cases, dry sites are deficient in these advantages. Greater areas of land have to be condemned, and larger and costlier dams are required, with vastly greater danger in case of accident. Really good sites are not a& abundant as one might wish, and the problem of developing storage on such sites is beset with difficulties of many kinds that greatly increase the cost. In 189T the author made a careful study of this question of flood control by means of reservoirs, in connection with an official investigation of the advisa- bility of building reservoirs in the arid regions. His view of the difficulties in the way of any general application of such a system is quite fully stated in his report, and the following extracts are directly in point : " It is the cost, not the physical difficulties, which stands in the way. It may be stated that as a general rule a sufficient amount of storage can he arti- ficially created in the valley of any stream to rob its floods of their destructive character ; but it is equally true that the benefits to be gained will not ordinarily justify the cost. The reason for this is plain. Floods are only occasional calamities at worst. Probably on the majority of streams destructive floods do not occur, on the average, oftener than once in five years. Every reservoir built for the purpose of flood protection alone would mean the dedication of so much land to- a condition of permanent overflow in order that three or four times as much might be redeemed from occasional overflow. One acre permanently inundated to rescue 3 or 4 acres from inundation of a few weeks once in three or four years, and this at a great cost, could not be considered a wise proceeding, no matter how practicable it might be from engineering considerations alone. The cost, coupled with the loss of so much land to industrial uses, would be far greater than that of levees or other methods of flood protection. * * * The construction of reservoirs for flood protection is not, therefore, to be expected, except where the reservoirs are to serve some other purpose as well." The above conclusions are still as applicable as they were when written. The subject has been given renewed prominence quite recently in connection with the Ohio River floods, but, before considering this particular application, atten- tion will be given to certain reservoir systems that have been proposed else- where, and particularly to one already built and put in operation by the Gov- ernment and which will be referred to frequently in the following pages. This is the system at the headwaters of the Mississippi the largest artificial reser- voir system in the world. The project of converting the more important of the numerous lakes around the sources of the Mississippi and its tributaries into storage reservoirs as an aid to navigation was originally proposed by Gen. G. K. Warren, and was first put into definite shape by Colonel Farquhar, of the Corps of Engineers. The plan then embraced a large number of lakes in Minnesota and Wisconsin, but only five sites have actually been improved. The dams were first built of timber cribs, but have recently been rebuilt in concrete. The combined storage is about 93,000,000,000 cubic feet. It is about twice the mean annual run-off from the watershed, and the system is probably the only one, except the Great Lakes, which equalizes periodic as well as annual fluctuations of flow. That is, it carries over the surplus from wet years to help out in dry years, and its utility Is, therefore, of the most comprehensive character. The cost of the five reser- voirs is remarkably low, although it is not now possible to tell the exact cost of the present structures on account of the mixture of old and new work ; but it probably does not exceed $750,000, including a lock in the Sandy Lake dam. This is only $8 per 1,000,000 cubic feet, or 35 cents per acre-foot on the basis by a rise in the surface equal to that in the outlet necessary to give the in- creased flow. But if the artificial reservoir has reached the limit of its allow- able filling, the outflow must be made equal to the inflow. If this limit is reached before or at the time of maximum run-off, then a quantity equal to this run-off must be let out of the reservoir. This contingency can never happen in a natural lake. The turning point where outflow and inflow balance each other is aiways after the crest of the flood has passed in fact at the time when the diminishing inflow and increasing outflow balance each other and the lake ceases to rise. In the case of the Yellowstone Lake (140 square miles), for example, this rise, in average seasons of snow melting, continues from ten days to three weeks after the inflow has reached its maximum, and surrounding streams have subsided materially before the Yellowstone River (at the lake out- let) ceases to rise. House Document No. 141, Fifty-fifth Congress, second session, p. 46. FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 89 of total capacity. It would be about twice this on the basis of the mean annual run-off from the watersheds. A large portion of the original project has been abandoned because public sentiment did not support its continuance. The author has always regretted this backward step, as he believes in developing to the fullest extent the excep- tional opportunities here offered for the storage of water. The available res- ervoir sites which could be cheaply improved in Minnesota and Wisconsin are sufficient to control, absolutely the floods of the Mississippi within the danger line for a long distance below St. Paul and to improve the navigation of the upper river very materially, while their value for industrial purposes is almost beyond estimate. In spite of the great and obvious advantages of this system, it has not yet received the popular approval that might be expected of it. In fact, about three years ago there arose a widespread sentiment in the community around the reservoirs that the system was, on the whole, injurious, that its disadvan- tages far offset its advantages, and a strong movement was organized to have it abolished altogether. For the purpose of investigating this matter a board of engineers was appointed, of which the author was a member. The board found that there was a general belief among the people below the dams that they actually increased the floods, while the people above complained bitterly of the back waters caused throughout that low country by filling the reservoirs so full. The water powers immediately below the dams complained that they were not getting even the normal flow of the stream, which was the case. Navigation interests below St. Paul have always been lukewarm in regard to the beneficial effects of the reservoirs, and the board was able to find only one- steamboat captain who would make a positive statement that the boating inter- ests derived any particular benefit from them. Some curious results developed in this investigation. It was found thaV great as the reservoirs are, conditions may arise in times of excessive precipi- tation that will compel them to discharge a greater quantity of water than would flow from the lakes in their natural condition. That is, they might actually operate to increase the floods if they should fill to their limit during a period of excessive precipitation. This very contingency nearly happened in the season of 1905. In like manner, during the period of lowest water, viz, in midwinter, the reservoir gates are closed down to about 400 cubic feet per second, and the great water powers, like those at the Falls of St. Anthony, are even worse off than in a state of nature; but this drawback is not so great as might be thought, because the powers are able to utilize most of the storage when it comes during the period of navigation. Such are some of the complications and drawbacks which are encountered in this reservoir system and which will surely be met in a system built up under less favorable natural conditions. Nevertheless, the board found that the system was in itself a very great benefit and that the lack of appreciation of its advantages was for the most part due to ignorance of what they actually were. At the public hearing the- opposition fell to pieces by the mere force of a better understanding, and it is safe to say that the system will never be abandoned, but will be extended along the lines of the original project. The United States Geological Survey has recently proposed quite an exten- sive reservoir system for the Sacramento basin, similar in principle, though smaller in extent, to that of the proposed Ohio system. The flood problem of the Sacramento River is the most difficult in the United States in proportion to its magnitude. In fact, it seems as if it will prove impossible to convey the- extreme floods of that river to the sea without extensive overflow of the bottom lands along its course. The proposition to control the floods to some extent by means of reservoirs was elaborately set forth in the paper by Messrs. Clapp, Murphy, and Martin, previously referred to. The subject had already been considered by the commission of engineers appointed by the State of California in 1904 to devise a plan of flood relief. The commission reported that, while- any help from such a source must, of course, be welcome in solving the prob- lem, it was very doubtful if such aid would be of sufficient importance to a The report of this board contains exhaustive data upon the system and its- operation. It may be seen in the Annual Report of the Chief of Engineers for 1906, p. 1443. (Appendix AA published separately in pamphlet form.) DO FOREST LANDS FOE THE PROTECTION OF WATERSHEDS. justify giving it much weight." In discussing the paper above referred to, the author stated that, while he had never visited the sites in question, it was his opinion that, as to most of them, it would not be possible to realize over one- fourth to one-third of the benefits claimed, and he based his opinion on the published records of the flood of 1907, which was the greatest in the history of the river. George L. Dillman, member American Society of Civil Engineers, in discussing the paper, flatly pronounced the whole scheme impracticable, and gave his reasons in detail for this conclusion. 21 Among thenx, he cited in one case the great value of the lands to be flooded by the reservoirs, which he claimed were altogether more important for agriculture than for any diminution of flood- ing which the storage might cause in the valley below. In another case he cited the difficulty, which always suggests itself to an engineer in considering the sub- ject, of timing the operations of the reservoirs so as to combine their effects to the best advantage, and particularly in keeping them empty in periods of pro- longed precipitation, so that their capacity may be available at the critical mo- ment. Other obstacles were pointed out, and the whole discussion presents ^another instance of the practical difficulties that stand in the way of any com- prehensive reservoir scheme for controlling floods. In 1903 the great flood of the Kaw River brought up the reservoir question again. Ex-Senator Burton, of Kansas, advocated the plan very urgently, stating in a speech at Kansas City that he " would have tens of thousands of reservoirs, beginning at the headwaters of the stream and coming right down." A board of engineer officers was appointed to investigate the practicability of providing against future disasters such as this flood had caused. The reservoir idea had made so deep an impression upon the public mind that a specific con- sideration of that feature of the problem was requested. In its report c the board found adversely to the scheme, on the ground that its great cost, con- servatively estimated at $11,000,000, and the annual loss from the withdrawal of the necessary lands from occupancy, conservatively estimated at nearly $600,000, would not be justified on the ground of flood protection alone. Owing to the character of the country, this last consideration was particularly strong. The only real justification of so extensive a system in a country so largely devoted to agriculture would be its use in irrigation and power, and, if it be- came necessary for these purposes, doubtless a portion of it would be built. The most elaborate study of this subject ever undertaken until very recently was made by the French Government, to determine whether reservoirs could be utilized to prevent the recurrence of such great disasters as the floods of 1856 in the valleys of the Rhone and other streams. A full resume of these studies is given in the author's report, already referred to, on " Reservoir Sites in the Arid Regions." The conclusion was the same that has been 'reached in every similar investigation. An interesting feature of the system then considered was that the reservoirs were to have sluices permanently open, so that it would not be possible to close them entirely. They would operate, it was expected, to hold back a definite percentage of flood discharge enough to keep the floods below the dams within safe limits. They would thus act automatically, just as forests are supposed to do. This was all right so far as the individual tributaries were concerned, but it was found, when the possible effect upon tributary com- bination in the main stream was considered, that by holding back earlier por- tions of freshets and prolonging their run-off, they might actually swell the combination in the lower courses of the main stream. Similar studies have frequently been made in all the principal countries of Europe, and in none of them, so far as the author is aware, has such a project on a large scale ever been undertaken or even favorably considered. Coming now to the Ohio River, the immense importance of that stream as a factor in the floods of the Mississippi makes the regulation of its flow a matter of greater moment than that of any other stream. The project of controlling the run-off of its watershed by means of reservoirs was urged very forcibly more than sixty years ago by Col. Charles Ellet. The subject has often been considered since, both in private and official investigations. The conclusion has invariably been that, great as the benefits of such a system would be if in exist- ence, the cost of bringing it into existence would be out of all proportion to such benefits.

FOEEST LANDS FOR THE PROTECTION OF WATERSHEDS. 91 The scheme has recently been revived in a more attractive form, with data not hitherto available, and at a time when a period of heavy floods and much loss therefrom has turned public attention strongly upon the subject. More- over, it comes supported by a comparatively new element in its favor the vast expansion of water-power development made possible by the electric trans- mission of energy. The new presentation of the project is by M. O. Leighton, Assoc. M. Am. Soc. C. E., Chief Hydrographer, United States Geological Survey, ,and is understood to bear the approval of both the Interior and Agricultural Departments. Mr. Leighton does not claim that his presentation is at all final or complete, but is rather a " statement of possibilities " which he believes are sufficiently promising to justify the Government in giving the scheme thorough investigation before further extensive steps are taken on present lines in the matter of flood control and channel improvement in the main rivers of the basin. Although an estimate of cost is submitted and certain conclusions are based thereon, it is stated that the data are too meager to give much confidence therein. Subject to these qualifications, the system, as set forth in Mr. Leighton's paper, embraces reservoirs on nearly all the tributaries of the Ohio; the total cost is estimated at .$125,000,000; the income from resulting water power at $20 per horsepower, and a certain computed lowering of flood heights on the Ohio and Mississippi rivers, and a corresponding increase in low stages, are given. The full details of the scheme are set forth in quite elaborate form. So far as the present criticism is concerned, the practicability of finding the necessary sites will be accepted, and only the estimate of costs and revenues and the deductions .as to benefits will be called into question. In their effect upon floods, admitting that all the reservoirs proposed can be built, the result must fall short of the claims put forth. If built at all, they must be built, as will be shown later, primarily for power development. It will never be possible, until science can forecast the weather more perfectly than it is yet able to do, to regulate reservoirs for the maximum benefit of both pur- poses. This consideration is sometimes made light of, but nevertheless it is one of real importance. For industrial purposes the reservoirs should be full be- fore the rainy season ends; for flood protection they should be so far empty that they may be able to hold back any flood-producing storm that is likely to come. While, doubtless, in a majority of years a middle course could be pur- sued that would not involve much risk on the flood side of the question nor much loss on the power side, yet there would surely come exceptional seasons the seasons of flood-producing rains or the seasons of great drought when the reservoirs would be caught too full on the one hand or too empty on the other. Their full calculated capacity would not then be available for either purpose, and it is difficult to conclude that this would not happen frequently. In partic- ular, if the reservoirs are really operated to prevent floods, it must often happen that dry weather will find them only partially filled, and that their full capac- ity will not be available either for power or navigation. This would not apply, of course, to a reservoir great enough to store all the run-off from its watershed in the greatest known flood, unless considerable storage were left over from previous years as is often done in the upper Mississippi reservoirs. Mr. Leighton's estimates are based upon the mean discharge of the streams, which is, of course, greatly exceeded, possibly doubled, in very wet years. In any case it would seem to be necessary to hold ample capacity in the reservoirs as late as the end of March each year to provide for possible emergencies; but if this is done there will be many years when the reservoirs will not fill. An important consideration in the use of the reservoirs for flood control is that of a proper combination of their outflow. To anyone who will try to figure out how this can be accomplished over a watershed of such vast extent, with storms arriving at different times in the various portions, with no way of telling when, where, or with what intensity they will arrive, with the varying dis- tances of the different reservoirs from those points where flood control is par- ticularly important, the problem seems almost impossible that is, impossible to realize the full effect based upon the aggregate capacity of the system. It is understood that Mr. Leighton has endeavored to do this, but it would be inter- esting to see the application to some of the great floods that might be designated. The author has seen the description of the proposed system only as pub- lished in Engineering News, May 7, 1908. He has had some correspondence with Mr. Leighton, and is under great obligation to him for a complete set of topographic sheets showing the various reservoir sites. 92 FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. For example, in the flood of 1907, which reached its maximum at Cincinnati and Pittsburg about the same time, no amount of holding back of the storm water on the upper Ohio at that time would have helped the situation at Cincinnati at all. Another important consideration in the effect of these reservoirs, as they would have to be operated to prevent floods, is the great change that takes place in a flood wave as it propagates itself down stream. The author is unable to tell from Mr. Leighton's paper to what extent he has considered it. The paper itself seems to indicate that the discharge held back by a particular reservoir produces a corresponding volumetric effect (not gauge effect, of course) at all points below, after making a due allowance of time for the transmission of the wave. This would be an erroneous conclusion. For example, a wave that might rise at Pittsburg from 100,000 cubic feet per second to 150,000 a day later and to 200,000 the next day, and then fall at a corresponding rate, would not at any point below produce a maximum increase of 100,000 second- feet ; and the farther away the point considered the less would be the increase. At Cairo, nearly 1,000 miles below, the same wave would take a much longer time in pass- ing, probably not less than a week, and the maximum increase would probably not be more than 25,000 second-feet. This is merely a general illustraflon, for exact data on the subject are not available. The problem is of such complexity that nothing but the results of long experience could establish a rule as to what might be expected in any given case; but it can be stated with certainty that the diminution of discharge at any considerable distance below the reservoirs for a given time would never, be as great as the amount held back by the reser- voirs in the same length of time, and that the quicker and the higher the flood the smaller the relative effect at all points below. Tt is only when such wave elimination merges into a constant quantity, continuing for a considerable time, that the full effect of a reservoir would be experienced at any point below. This, in fact, is what would actually happen in the contrary case of the low- water season when the reservoir discharge is kept up for a long time. Still another feature in the high-water effect of such reservoirs is the demand for water for power at all times. If there should ever result any really general use for all this water, as is predicted, then the consumption for power would make a considerable river in itself. Now, this much can not be shut off in any case. Street cars and shops must run and houses must be lighted, whether the flood is ruining the lowlands or not. An example of this occurred in 1905 on the upper Mississippi, where the outflow from the upper dams was cut down to a minimum to reduce the flood in the valley at Aitkin, which was then being overflowed by the river. The mill at Grand Rapids, just below the reservoirs, made a strenuous protest, and even threatened legal proceedings to compel the release of the full normal flow of the river. Considering all the foregoing features of the operation of the proposed sys- tem, even if every reservoir were built with the full estimated capacity, it would be extremely fortunate if 75 per cent of the predicted results, either in flood protection or in aid of navigation, could be realized. It is in the matter of cost, however, that the weak point of Mr. Leighton's system appears. Judged by any reasonable .standard, his estimates are hope- lessly wide of the mark. The method itself of getting at a basis of cost is inad- missible. For example, in determining a unit of cost for that class of reser- voirs which embrace the greater portion of the total storage, the figures for nine reservoirs are taken, counting as one the whole upper Mississippi 1 system. Only the Mississippi system has been built ; two others are under construction and six are merely projected. In accordance with almost universal experience, and espe- cially in view of the great advance in prices of all kinds since these estimates were prepared, it must be expected that these works, if ever built, will cost from 25 to 50 per cent more than the estimates. Three of the projected dams are of the relatively cheap rock-fill construction, which would be inapplicable to most of the Ohio dams from considerations of safety. The controlling element, however, in the unit estimate is the Mississippi system, whose capacity is nearly one-third of the whole group considered and whose unit cost is only about one-seventh of the average cost of the others. The use of the Mississippi reservoirs in any way as a basis of estimate for the Ohio system is wholly inadmissible, because of the dissimilarity of sites. The Ohio sites, with one exception, are dry sites totally different from the lakes of Minnesota. Even the latter reservoirs could not now be built for three times what they have actually cost the Government. The flowage lands em- braced about 80,000 acres, which were nearly all reserved while yet belonging FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 93 to the Government. A few recent purchases of additional lauds found necessary, and the experience now being met in acquiring the flowage rights for a reser- voir at Gull Lake, show that if these lands were to be bought to-day they would cost from $10 to $25 per acre. The right of way alone would now cost twice as much as the dams. Compare any one of these structures Leech Lake, for example with a representative masonry dam like the Cheesman dam on the South Fork of the South Platte River above Denver, Colo. The author is familiar with both sites and once submitted a plan and estimate for a structure on the Cheesman site almost exactly like the one built. Lake Cheesman is a more favorable site than most of those on the Ohio system, for, although its capacity is not as great as some, the dam site is exceptionally advantageous, one of the most per- fect in nature a very narrow gorge in solid granite, with a natural spillway already provided. In several of the Ohio sites entire towns will have to be removed, important railroads will have to be relocated, a few mineral proper- ties will be destroyed, and, in nearly all, road systems will be seriously dis- arranged. None of these conditions were encountered to anything like the same extent in the Cheesman site. Undoubtedly its unit cost, which is estimated at about $250 per 1,000,000 cubic feet, was as low as can be possibly realized on the Ohio system as a whole. Compare this with less than $5 for Leech Lake or $8 for the whole Mississippi system. A recent example of projected storage is that presented by the late George Rafter, M. Am. Soc. C. E., for the Genesee River near Portage, N. Y. Owing to the moderate height of dam (apparently less than 150 feet) and the large capacity of reservoir (15,000,000,000 cubic feet), this is believed to compare favorably as to unit cost with the Ohio system. The estimate was $216 per 1,000,000 cubic feet. If it were to be built under the present conditions of the market, it would doubtless cost $250. It is understood that later investigations have shown that Mr. Rafter's estimate is only one-half large enough. In 1895 the author made an extensive examination of storage possibilities in Ohio, near the divide between Lake Erie and the Ohio River, for the purpose of providing a water supply for certain projected canals. He prepared estimates for two sites on the head waters of the Cnyahoga, for one site at the head of the Scioto, and for one at the head of the Great Miami. The estimates were based upon actual surveys and are given in detail in the report upon the sub- ject. The type of construction was not expensive. The total capacity was 11,000,000,000 cubic feet and the unit cost $300. To-day it would be at least $350. Most of the proposed sites for the Ohio reservoirs are not advantageous sites The topography of the country is unfavorable. The sites are not compact basins, like those occupied by lakes or ponds or mountain meadows, but are, for the most part, trunk valleys with numerous tributaries, nearly all of them quite narrow. They may be roughly compared to the form of the hand with the fingers outspread, the dam occupying the position of the wrist. The ends of the fingers are frequently many miles from each other and from the dam. Numer- ous villages occupy the valleys. The road systems of the local communities traverse them. The disadvantage that will result to public travel by forcing it out of these natural routes over the hills and around the ends of the fingers will be very great. The lands lying between the fingers, in some instances, will be so far cut off from convenient access that their value will be much impaired, and damages will have to be paid on that account. In several instances the necessary changes in railroad alignment in the hilly country will be extremely costly, if not impracticable. A great many cemeteries will have to be removed, which means not only the cost of removal, but extensive purchase of lands out- side. Such drawbacks are, of course, encountered in all similar work, but they are excessive in these sites. They are mentioned solely from their relation to the question of cost. No one can examine the maps of these sites and not be convinced that the cost of right of way and damages alone will considerably exceed Mr. Leighton's estimate of the entire cost of the system. An element affecting cost is that of safety. Owing to the situation of many of these proposed reservoirs the results of failure of the dams would be so appalling that no chances can be taken. The structures can be made safe, of course (except against earthquakes), but it will cost money. Nothing short of the highest type of construction masonry for all the larger dams can be con- sidered. Mr. Leighton has cited certain dams upon the integrity of which great House Document 278, Fifty-fourth Congress, first session, pp. 78, 83, 86. 94 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. interests depend as evidence of the confidence of engineers in these structures, but if he will apply their costs, particularly those of important structures in Europe, 'to his proposed system the money value of safety will mount up to a prodigious figure." A feature of this question of safety often overlooked is the depreciation of the market value of property, due to its location below a dam, where failure of the dam would mean a disaster of great magnitude. However safe the struc- ture may be many people would not purchase property below it, and its market would be correspondingly diminished. While such loss can hardly be made a subject for damages, it is a real loss to the owners. These reservoirs being built for flood protection, the sluices must be very large, so that at times they can be discharged practically as fast as the water runs in. This will be necessary during periods of prolonged precipitation in order to keep the reservoirs from filling too full before the danger is past. This detail of construction will add largely to the cost. Taking everything into consideration on the most liberal basis, it is evident that this system can not be built for less than $250 per 1,000,000 cubic feet. The probable increase in the value of property to be condemned before the system could be built and the present scale of prices of labor and material make this figure a minimum. This would swell the cost of the whole system to over four times Mr. Leighton's estimate, or over half a billion dollars.* This is not all, however. It appears that the complete development of the reservoir system as proposed will take from industrial use probably 1,500,000 acres of land, including the lands actually overflowed, the margins subject to damages, and sites for the dams and various structures appurtenant thereto. These lands will be in large part, by the very fact that they lie in valleys suitable for storage grounds, the best lands in the localities. Sooner or later they are bound to come into agricultural use, and with proper cultivation their annual net-revenue value will be at least $5. per acre. If utilized for forest culture they ought to yield 500 feet board measure of lumber and 1 cord of wood annually per acre. The value of the land for this purpose ought to be as great as the figures just given. It thus appears that the occupancy of these lands for reservoir purposes will take from the community an annual product of at least $7,500,000 worth, and probably more. The reservoirs will store about 2,150,000,000,000 cubic feet of water. Assume that this can all be utilized for water power, with the average head of 200 feet, giving theoretically about 1,000,000 horsepower per year, or 1,280,000 horse- power at 80 per cent efficiency. At $5 per horsepower (the bnsis for this figure will presently be considered), the revenue from water power will be $6,400,000, which falls short of the loss resulting from withholding the sites from pro- ductive use. The recent failure of the Hauser Lake Dam, on the Missouri River, near Helena, Mont., is a good illustration of how the unexpected may happen. Here was a dam built of steel and concrete, two materials whose properties are thor- oughly understood. The case was one which " ordinary engineering " might be expected to hsindle successfully. The public had reason to feel confidence in the structure. Yet " it fell, and great was the fall thereof," not only in the total wreckage of the dam, but in the losses caused along the valley below. The accident affords also another illustration of the omnivorous claims put forward in these days in the supposed interests of forestry. The disaster was promptly cited as an example of the havoc wrought by floods in a country with- out forests. The normal flood discharge of the Missouri at this point is 20,000 cubic feet per second ; for 1907 it was 26,000 cubic feet ; the maximum on record is about 50,000 cubic feet. At the time of the accident the discharge was about 7,000 cubic feet. 6 Recent examinations of certain sites, embracing nearly 70 per cent of the proposed Monongahela storage, indicate that the whole Ohio system will cost at lenst a billion dollars, and possibly a billion and a half. c The sanitary feature has not been considered, although it is one of some importance. The laying bare of large areas of reservoir bottoms in the heated portion of the year is objectionable, but it is not a matter affecting the element of cost. Neither is much stress here laid upon the danger to the reservoirs from silting up. This is not a region of heavy silt movement. In most of the reser- voirs the process will be very slow, and we may safely leave to distant genera- tions the task of dealing with this problem whenever it reaches an acute stage. FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 95- Viewed in the light of the foregoing exposition, the weakness of the reser- voir scheme as a measure of flood control or for improving navigation is at once apparent. The question is, Will the ends justify the means? If the ends sought could be attained in no other way possibly they might; but they can be, and for a small fraction of the reservoir cost. Consider the estimate already given of $500,000,000. Take $40,000,000 and reinforce the entire levee system of the Mississippi. That will make it impregnable as safe as any of the pro- posed reservoir dams. Take $60,000,000 and revet the banks of the Mississippi wherever necessary from Cairo to the Gulf. The reservoir project does not touch this important matter at all. Devote whatever sum is necessary to the protection of the bottom lands of the Ohio basin. Give Cincinnati and Pitts- burg each $10,000,000 to assist in local changes necessary for complete flood protection. Devote a sum to navigation such as our engineers have never dared dream of, and the Government will still save more than Mr. Leighton's estimate of the whole cost of the reservoir system. The more closely this reser- voir proposition is scrutinized as a scheme for flood prevention the more im- practicable it appears. It is only a trade-off at best. It is giving up to per- petual overflow valuable lands to save others from occasional and even rare overflow for short periods. Now if at less cost these low lands can be better protected by other means, thus leaving both the valley lands and reservoir sites open to productive use, how much better it will be. If the author were to venture a criticism on Mr. Leighton's attitude in this matter, it would be that he has not fully appreciated his responsibility in bring- ing forward again this old proposition without fuller consideration of its organic defects. This is well illustrated in the opening paragraph of his paper, in which he says : " This report will be confined to a statement of possibilities. There will be no attempt to prescribe methods for treatment of each local modifying condi- tion that will be encountered in the prosecution of the plan here proposed. Such features are merely collateral, and their proper disposition is a matter of ordinary engineering." This is a complete reversal of his obligation in the matter. The "possibili- ties " of reservoir control have long been recognized. The logic of the plan is well understood. It has always appealed to the popular mind. In particular, reservoir control of the Ohio floods has been advocated for more than sixty years, and its possibilities have often been investigated. The plan has been uniformly rejected on one ground, viz, that as a scheme for flood control and navigation improvement its benefits would not justify its cost. It is, therefore, incumbent upon whoever revives the scheme to come well fortified upon this particular feature. He must give some study to the treatment of " local mod- ifying conditions." It makes a difference whether he can go to a great natural lake like Winnibigoshish and store 40,000,000,000 cubic feet of water for a mere trifle, or whether he must evict whole villages, disturb railroads and highways, absorb valuable lands, and possibly subject communities to serious risk. These are the questions upon which the success or failure of the scheme depends. Yet Mr. Leighton brushes them aside, as it were, with a wave of the hand, as " merely collateral " features, matters of " ordinary engineering " only. Here is the weak point of his project. Weighed in the balance of practical accom- plishment, either for flood control or navigation, it will be found utterly want- ing, and the development of the system, as has always been held, will have to be based primarily and mainly on its value for industrial use. For the same reasons that the development of a great reservoir system in the far West is justified by its industrial value its use for irrigation so a reservoir system for the Ohio, or any other rivers, except in a few unusual cases, must depend primarily upon its industrial value the development of power. In pursuing his criticism further, the author would not be understood to be " knocking," as current slang goes, the feature of the reservoir system just mentioned, because, in his judgment, there is no one thing in the present move- ment for the conservation of our natural resources that is more important than storing the flood waters of our streams for power development. It stands in the same category with the preservation and extension of our forests. It stands on even a surer basis, for man, either willfully or through neglect, can destroy the forests, but he can never diminish in the smallest degree the power of run- ning water. It is a great solar engine, perennial and perpetual in its action. a Report Mississippi River Commission, 1896, p. 3457. 96 FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. It requires no aid from man in its production. All he has to do is to utilize it. Providentially, electricity has unfolded its power to transmit this energy over great distances, and has thus made practicable a development which would otherwise have been impracticable. In time water power will replace coal and oil and will become" the one great source of power, unless discoveries are made which are not now foreseen. The author thoroughly believes in developing this power through public agencies and preserving it from private ownership and control. His present criticism is directed not at all at the principle involved, but at the extravagant expectations now being fostered as to the possible rev- enue which the Government may derive from such development. The quantity of power estimated in the publications of the Geological Survey and the Agricultural Department are based upon an assumption that most engineers will question, viz, that 90 per cent of the fall of our rivers can be utilized in effective head upon water wheels. This is too great a figure. The most thoroughly developed river in the United States, namely, the Merrimac, in New Hampshire and Massachusetts, develops only TO per cent of the total head. Taking all the streams into consideration, it seems hardly possible that more than 50 per cent of the fall can be utilized. When the fall of a river is uniform, even if quite steep, the cost of long canals or high dams necessary to concentrate it at one point often prohibits development altogether. From altitudes of 3,000 feet the Missouri and Yellowstone, for example, descend to the sea with a total energy of possibly 5,000,000 horsepower, yet comparatively little of this can be developed advantageously. It is only in those places where nature has helped out by concentrating the fall at cataracts or rapids that water-power development is commercially profitable. At low dams, such as are ordinarily built at lock sites, the head is often nearly all obliterated during high water. How far storage may affect these drawbacks can not be said, but it should of course help a great deal. The official estimates of flow for non- regulated streams are based on two weeks' average lowest flow. This may probably be extended materially with reservoir aid or supplementary steam power. Possibly the total estimated horsepower may ultimately be realized. When it comes to the royalty which the Government may receive for these water powers, if developed by private interests, the price of $20 per horsepower, adopted by the Geological Survey and the Agricultural Department, is wholly out of the question under present conditions. Possibly the author does not understand what the figure is intended to embrace. From Mr. Leighton's articles the inference has been drawn that wherever the work of the Government ren- ders power available which was not available before, either by building dams, as at lock sites, and thus creating a head, or by storing water which might supply powers below with more than they would have without, the value of the power thus rendered available should return to the Government $20 per horse- power per annum an " exceedingly low price," as Mr. Leighton puts it. 6 It is not understood that the Government is to build the power plants, but that this is to be done by the interests availing themselves of the privilege. Estimates of undeveloped water powers on many streams of the Atlantic slope by the Geological Survey leave one to infer that these powers are considered worth at least $20 per horsepower to the Government even without dams or reservoir aid. While the statements are not clear as to what is actually meant, the various references to resources to be derived by the Government from these powers lead to the above conclusion. It would be of advantage in considering questions involving these published estimates, if the basis for this $20 price or royalty could be made more specific. Under present conditions, or such as can be reasonably foreseen, no such royalty is possible except in extraordinarily favorable circumstances. Efforts a There has recently been invented a device called a " fall increaser," an adap- tation of the Venturi meter, by Clemens Herschel. M. Am. Soc. C. E., which promises to utilize the extra flow of streams in time of flood water and low heads to increase and maintain the head upon the wheels. If this invention proves a success, as seems probable, it will be an immense gain to all water powers of low head subject to large fluctuation, as would doubtless be the case in very many of those under consideration. 6 On the Youghiogheny alone, where it is proposed to install a slack-water system comprising three locks and dams, at an expense of $600,000, proper de- velopment of storage will insure the production of a minimum of 4,100 horse- power, the value of which, reckoned on the exceedingly low price of $20 per horsepower year, would produce a total income of $82,000. FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 97 which have been made to derive a satisfactory revenue from existing powers do not justify any such prospect. The many and various practical difficulties in exploiting these powers are rarely appreciated by those who have not en- countered them in actual experience. The cost of water-power development is restricted to narrow limits, if it is to compete with coal. An engineer of high standing, whose life work has been connected with water-power develop- ment, says: " I am advised that, with good coal at $2 per ton in this territory, the cost of fuel per horsepower per annum (300 days of 24 hours each) is less than $8 for producer gas engines and for steam power about $12.50 in large size equipments. In many localities coal will cost even less than $2 per ton, allow- ing thus a still wider margin. If we now consider the usual and unavoidable handicaps and incumbrances to all water-power installations, such as floods, low water, ice flow, back water, etc.. we have conditions which will make it a serious study for any power consumer to determine if the balance is not con- siderably against water power in that particular territory, at this time, from a purely commercial standpoint. At any rate it must be obvious that no such rate as $20 per annum per horsepower can be paid to the Government by any power user for the right to draw the water only, and besides this, stand the expense of installing and operating the water plant." Another hydraulic engineer of national reputation says : " I think that as a general proposition the suggestion that all water powers to which the Government consents should pay royalties, and especially where the parties own their riparian rights, would tend to defeat the development of most water powers and would certainly very much curtail the number of water- power developments. I am impressed with these conclusions because of the present difficulties in financing good water-power propositions." In Power, May 19, 1908, is an article by Henry Docker Jackson, in which a critical comparison is made between steam and water power. In this article occur the following tabulated estimates of cost of installation and of annual operation, based upon a (theoretical) installation of 1,000 horsepower. The costs are averages of a number of different plants : PLANT COST. Building and works Engines boiler, etc Turbines and generators Transmission lines, etc., 20 miles 810,000 i 48,000 I 15,000 | 17,000 j 40,000 I 73,000 134,000 FIXED CHARGES.

From the last part of these tables, it is very evident that a royalty of $20 per horsepower would turn the scale wholly in favor of steam under all conditions of load. In fact, it is reasonably certain that $5 per horsepower per annum would be an outside figure, and even this would often be prohibitory. The situa- tion will not necessarily be improved by the growing demand for power, but rather by the diminishing supply and increased cost of fuel. So long as coal can be had for anything like present rates no very great charge can be realized from water power wherever fuel is readily available. Under present conditions $120 per horsepower may be considered as an average limit for first cost of a water-power plant, if it is to compete with steam. A charge of $20 per horse- power per annum would be equivalent to doubling this first cost. A variable element in the cost of water-power development is the distance from plant to market, or the length of the transmission line. When this is very great, as in numerous plants in the mountain districts of the West, it makes a large addition to cost of installation and must correspondingly reduce the roy- alty that could be paid for the power itself. An interesting example of what the Forestry Service has been able to do in this line with unimproved water powers is that of a recent permit for the devel- opment of a large power in the Cascade Mountains within the forest reserve. The beneficiary of the privilege is required to pay annually for " conservation " 10 cents per 1,000 kilowatt hours equivalent to G5 cents per horsepower per year continuous running. The right is retained by the Government to increase this charge 25 per cent every five years for a period of forty years, after which the whole arrangement may be readjusted. The maximum charge at the end of the forty years will, therefore, not exceed $4 per horsepower. The only way in which a rental of $20 per horsepower can be obtained with any degree of certainty, and that in only a small proportion of the localities for many years to come, is for the Government to build the plants. It is admitted that this suggestion will grate harshly on many ears because of its newness and its departure from the established ideas. But a little consideration will show it to be not only the best way for both private and public interests, but really the only practicable way. This may be illustrated by a concrete example : The Government has just completed a survey and adopted a project for the construction of what is known as the Lake Washington Canal in the city of Seattle. It is a canal to connect Lakes Union and Washington with Puget Sound. The discharge from the tributary watershed which will flow through the canal averages about 1,500 cubic feet per second. The mean fall at the lock site is about 15 feet. The theoretical energy is about 2,500 horsepower, but owing to the tidal fluctuation and variations of flow with the seasons (which can not be wholly eliminated on 'account of the necessity of limiting fluctuations of level in the lakes to about 3 feet, and also to the requirements for canal power, lockage, and leakage), it was thought that about only 1,000 horsepower could be depended upon with certainty for outside use. As this poVer is located in the heart of a great city, it seemed as if it ought to be turned to good account in helping bear the cost of maintaining the canal. Efforts to obtain tentative propositions for developing this power were, how- ever, wholly fruitless. The plan was then considered of having the Government build the plant and lease it to consumers of power. On this basis a tentative offer was obtained from a responsible consumer to take the plant, operate it, keep up all repairs and pay the Government $18 per horsepower year. Prob- ably by the time the canal is completed, a figure of $25 can be obtained, and as more than 1,000 horsepower will probably be developed, it is likely that the Government will receive upward of $30,000 per year for this power enough to pay the entire cost of operating the canal. The extra cost to the project of adopting the power-plant feature is $220,000, so that the revenue will be nearly 14 per cent upon the expenditure. In recommending this plan to the department, it was pointed out that the true advantage of the Government, even apart from the revenue expected, favored its adoption. It simplified the whole relation between the Government a Mr. Leighton cites the falls of the Ohio as an example of an opportunity to develop 110,000 horsepower by aid of his proposed reservoir reguhition. This, he states, at $20 per horsepower, is 3 per cent interest on $73,000,000. To any- one familiar with the physical conditions involved in the development of this power it will appear extremely doubtful if any company could guarantee to deliver continuously this amount of power, even with the full aid of reservoir regulation, and pay any royalty whatever. FOKEST LANDS FOR THE PROTECTION OF WATERSHEDS. 99 and the consumer. If private interests were to build the plant, they would jicquire vested rights which would always stand in the way of future control mid lead to complications if it should become necessary to terminate the arrangement. With the plant in the possession of 4;he Government and the users standing simply in the relation of lessees for a limited period, without great initial expense on their part, and with freedom on the part of the Gov- ernment to control the arrangement without the complication of private owner- ship, the whole plan would stand on a simple, practical, business basis. This view prevailed with the department and is now before Congress for adoption, being possibly a departure in this line. The principle involved in this case should be given general application. In addition to avoiding complications with private ownership, there are other im- portant considerations. When a power is developed or a reservoir built, it should be so planned from the start as to bring out its full possibilities. A private company can rarely do this. Generally its scheme does not require it, nor its resources permit ; but a site once occupied by an inferior work may be perpetually barred from complete development. Moreover, in any such work, the Government can derive a greater benefit than any private individual or association. A private company must build for the immediate future; it can not wait long for dividends and it can generally realize only on such applica- tion of the power as is possible in the immediate vicinity. The Government, on the other hand, derives all the benefits which come from the stored water anywhere on its course from the reservoir to sea. These benefits arise from all the powers through which the water flows; from the improvement of navi- gation and the prevention of floods and from every other use to which the water can be put. Furthermore, the Government is building for all time, while the individual builds only for the present and near future. The case is similar to that of landlord and tenant. A tenant can not afford to make im- provements on the farm because it is not his and he may remain on it only a short time. The most he can do is to get out of the farm what he can in its actual condition. The owner, on the other hand, can put in improvements which yield him no immediate return because he holds the property long enough to realize upon them. So it is with the Government; it can wait for realization upon its improvements much longer than a private company. In forestry, for example, no individual can afford to wait from three to ten gen- erations for a crop. Only the Government or a great railroad corporation can do this. Likewise, in building great reservoirs, no private company can build for the distant future. It is only the landlord that can make such far-reaching improvements upon his estate. Wherever, therefore, there arises any real demand for power development at the site of any government work, as a lock and dam, the judicious course would seem to be for the Government to prepare a comprehensive plan for development capable of being carried out progressively as the market for power may justify. Let it then build the plant as fast as needed and lease it to private agencies under suitable restrictions. Likewise, when the building of a reservoir prom- ises to be of obvious utflity, and the conditions are such as to make it properly a subject of government adoption, let the Government build it, utilizing the water in its own plants below and collecting a revenue from private plants that may use it. Whenever at the time of construction there is a direct return in sight of 2 or 3 per cent, it should be considered justifiable from a Government point of view. The certain enhancement ia the future value of such utilities and the incidental advantages in flood protection and navigation make this a conserva- tive proposition. That difficulties will be encountered in deriving the full return from its work to which the Government would be entitled can not be denied. This would be the case, particularly wherever it is a question of compelling existing power plants to pay for the extra water they might receive through government storage. This question came up before the Mississippi Reservoir Board in regard to the powers at St. Anthonys Falls which derive such benefit from the reservoirs. The board remarked as follows on the subject: " It may be urged that if the incidental benefits of the reservoirs to the water- power interests are so great, these interests should be required to contribute something to the maintenance of the system. There would doubtless be a will- ingness to do this if a satisfactory method could be found. But there is no practicable method of enforcing any charge upon the use of this water. Where water is taken in a separate channel from above a dam or lock and conducted to a mill, it is a simple thing to measure it and to cut it off if it is not paid for. 100 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. But when it must be let into a natural stream, where it mingles with the run-off from below, it is impossible to determine what proportion of stored water the mill may be using or to enforce its nonuse if not paid for. But, if such an arrangement is not practicable, that fact does not constitute an argument against the reservoir system. So long as te reservoirs are performing the service for which they were created, every additional benefit derived from them is only an additional argument in their favor." These disadvantages will adjust themselves in time. Such, in the opinion of the author, must be the basis of any great reservoir system in our country industrial use. Even in the uniquely favorable condi- tions at the headwaters of the Mississippi, no one can doubt that the real pur- pose being served is that of mill power, whatever the theory upon which the reservoirs were built. The great system of the far West is being built for irrigation, power, and domestic supply. So on the Ohio and other eastern streams, the system must rest upon an industrial basis and expand only as industrial demands justify. The innovation involved in building reservoirs with public funds for these uses is admitted; but it is no greater than it was ten years ago to build them for irrigation. When the author was investigating that subject in 1896-97, he found a widespread opposition throughout the arid regions against government control of irrigation works in any way, and in his report he went no further than to advise the building of reservoirs for giving the people more water, leaving its distribution exactly as it was before. Yet in the short space of ten years public sentiment has completely changed, and to-day no one questions the wisdom of the broader plan upon which these works are being carried out. So it will surely be in regard to reservoirs in all other parts of the country. The principle is the same. It may be accepted that only the general Government can do this work in the comprehensive way in which it ought to be done, because only the Government can reap all the benefits ; only the Government can wait the long periods necessary for full returns ; and only the Government has the necessary resources to make expenditures on the re- quired scale. These points will not be enlarged upon, and the many and cogent reasons why this is so will not be given. The trend of public thought is all hi that direction. The old idea that the Government can riot execute great works or small as cheaply, efliciently, and expeditiously as private agencies is fast being dispelled, and the vast benefits which the people derive from public con- trol of important enterprises are coming into fuller recognition all the time. The foregoing remarks should not be construed as in any way rejecting the idea of local help by States, counties, cities, or even private agencies. It often happens that public works have a special local importance in addition to their public value. It is just and proper in such cases that local aid be given. This principle is now fully incorporated in river and harbor legislation. For ex- ample, the Lake Washington Canal, which will be of very great importance to the city of Seattle, is a joint enterprise between the Government and the city, the latter paying fully one-third of the cost. The cooperation between the United States Geological Survey and the several States, in preparing a contour map of the country is an example on a large scale. The principle ought to find an extensive application in the establishment of national forests throughout the country. CONCLUSION. This paper will be closed with some reference to the relation of navigation to other uses of our streams and to certain legal obstacles that stand in the way of comprehensive me.'isures. That the improvement of our inlnnd waterways should be organized upon a more rational system than it has ever been ; that the reciprocal relation between navigation, water power, etc.. should be given practical recognition; above all. that the prosecution of these works .should be placed upon the same sure basis as is the construction of the Panama Canal, with positive assurance that, when once commenced, funds will be forthcoming for their prompt completion, would seem to admit of no doubt. How far navigation should be correlated, in improvement work, with other uses of the streams is an open question. Water power and navigation are in many cases so closely related that they will have to be considered together. In regard to soil wash, no such intimate relation exists. To whatever extent soil .erosion now exceeds that of former times it relates almost exclusively to culti- vation and has no appreciable influence upon the channels. Its control is of far greater importance to agriculture than it is to navigation. This is also true of irrigation, which, so far as it affects navigation at all, affects it in- FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. 101 juriously. If the development of irrigation is ever carried to the length that we hope it may be, it will cause a heavy drain upon the low-water flow of the Missouri. Sacramento, San Joaquin. and the Columbia rivers (not important as to this stream), the only navigable waterways of consequence that are affected by it. Except for this fact of drawing water from the stream, irri- gation has no relation to navigation. Forestry, irrigation, and prevention of soil wash are all related to the con- servation of the vegetable resources of the country. They are kindred purposes and should naturally fall under the same administrative control. Navigation is a function of transportation, which is a very different subject. Water power is becoming more and more closely related to it, and these two subjects natu- rally go together. It must not be expected that the character of works for river regulation can be materially changed by means of reservoirs, forests, or soil- wash prevention. Levees and bank protection, locks and dams, dikes and dredging will continue to be standard methods of river improvement in the future as in the past. The accumulated experience of centuries in all civilized countries can not be set aside in a moment. In particular, flood protection is not likely ever to find any complete substitute for levees. They have been used extensively the world over throughout recorded history. People who think only of the Mississippi and the Po. when levees are mentioned, little understand to what an extent " diking " is resorted to wherever rich bottom lands have to be guarded against floods or tides. Some of the Quest agricultural lands in the world are behind levees where almost perfect security is felt. No class of river control is in more extensive use, none is better understood, and from none has the world, throughout its history, derived greater security and benefit. Municipalities, like Pittsburg, Cincinnati, and Kansas City, must look in the main to their own efforts for protection against floods. In particular they must reject absolutely the delusive promises of forestry. These cities are tres- passers upon grounds dedicated by Nature to a condition of overflow. They have occupied these grounds and placed themselves in the way of the floods deliberately and with their eyes open. They have gone farther than this, and iu many instances have encroached upon the channels and have thus made the Hoods worse than they used to be. It is not for them now to look for outside deliverance, but they themselves should grapple courageously with the problem. In most cases these problems admit, if not of complete solution, at least of a very large measure of relief. The maxim that Providence helps them who help themselves may also apply to the Government. Cooperation in connection with its regular work, either in channel improvement or in the building of reservoirs, would doubtless be given. The disposition which must be met and overcome is to let things go as they are, trusting blindly to chance to deal more kindly in the future. This supineness of spirit and the enervating reliance upon indefinite future relief through the agency of the Government must be replaced by self- reliance, and these great industrial centers must rise in their own might and free themselves from their bondage to these ever-recurring catastrophies. In Boston. Chicago. Galveston. San Francisco, and even in that lusty young giant of the Northwest, Seattle, are examples enough of what an aroused civic spirit can do in the direction of self-aid. The part that reservoirs will play in the larger problems of channel improve- ment and flood control on the great rivers will be in the nature of an insur- ance. Every cubic foot of water taken from the crest of a flood and released when the rivers are lowest is pro tanto a benefit. If the great floods of the Mississippi can be cut down by so much as a foot through reservoir storage, it The author is not closely familiar with the situation at Pittsburg and Cin- cinnati, but he is familiar with that at the two Kansas Citys where, in 1903, the greatest loss occurred that any American city ever sustained at the hands of a river flood. He speaks from the results of careful study on the ground when he states with the utmost positiveness that for approximately $10,000,000, with such aid as might reasonably be expected from the Government on the Mis- souri River front, the flood problem of the Kaw and Missouri in that hive of industrial enterprise known as the West Bottoms can be solved absolutely; the too small area of these bottoms can be increased by upward of 200 acres; two- thirds of the bridges in the same area can be eliminated ; that prodigious bar- rier to free movement the Kaw River-^-can be practically removed or placed where it will not be in the way ; and the general situation can be so improved that the resulting benefits, wholly apart from that of flood protection, would be well worth the cost. 102 FOREST LANDS FOR THE PROTECTION OF WATERSHEDS. will be an immense gain ; and the same will be true if the low-water stages cau be increased by two or three feet. Whether the much greater results expected by Mr. Leighton can ever be realized is a question which the future alone can determine. A word, finally, concerning the legal obstacles in the way of a broad Govern- ment policy looking to the development of national forests and the storage of water on an extensive scale. The expansion of Government work into fields of obvious utility is often blocked by the structure of our Government through the bar of constitutional prohibition or at least lack of power. It is said that the purchase of lands for the rearing of forests for timber alone is unconstitu- tional, and that the same is true of the storage of water for any other purpose than navigation ; and yet, forests for timber and reservoirs for power must always remain the real justification for public expenditure along these lines. To the average understanding the distinction between things constitutional and things unconstitutional is often hard to discern. The Government is now expending millions in storing water and conducting it upon land whereby the products of the soil may be obtained. It is applying this water to both public and private land, or to lands that were in private ownership when the projects began. Is there any real difference between providing the power to raise sugar beets, for instance, and that for manufacturing them into form for human con- sumption and transporting them to the consumer? Are not the last-mentioned purposes quite as necessary as the first? And again, is there any distinction in principle between improving a river so that boats can navigate it and improv- ing it so that it may provide power that will transport produce by laud as well as by water? Again, the Government has accepted gifts of land like the Yosemite Valley and the Muir Redwood Grove, to be given over to the enjoyment of the people and involving perpetual expenditures for maintenance in the future. It has traded lauds of its own for lands with which it has parted ownership. It reserves vast areas to-day which might be private lands to-morrow. What is the distinction of principle between doing all these things and buying outright lands that are needed for the same or similar purposes? They are distinctions without real differences. They concern the letter and not the spirit, and they can not stand whenever the interests of the public really demand their abrogation. Still, it is probably a fact that federal 1 authority to buy lands for forest culture alone and to create reservoirs for industrial use exclusively, would be considered by the courts as transcending the power of Congress under the Constitution, and it is this fact that forces those who believe in having the Government do these things to strain the truth by attempting to prove that they are necessary for navigation and for the prevention of floods. It enforces a policy of indirection instead of permitting these things to be done squarely for their real purpose and as a matter of right. In his address before the Judiciary Committee, in its hearing on the Appalachian bill, Mr. Pinchot stated that that proposition must stand or fall upon the theory that the forests regulate stream flow, and are therefore useful to navigation. Did he not refer to the particular point here under consideration that on any other theory the measure would be unconstitutional? Surely he did not mean that the cause of forestry itself must stand or fall upon any such issue. Does not this situation suggest the necessity for an important initial step tvhich shall sweep away these artificial barriers and let these great questions stand or fall on their intrinsic merit? If the upbuilding of new forests, if the storing of our flood waters, are necessary measures for the welfare of the nation, the way should be cleared for their accomplishment. There may be differences of opinion about amending the Constitution in the interest of uni- form divorce laws, popular election of Senators and the like, bur. if we may judge from the universal agreement upon the particular subjects here consid- ered, every State in the Union would ratify an amendment giving to Congress the power to legislate for the conservation and development of the natural resources of the country. The author should possibly state, in justice to the otncinl body of engineers to which he belongs, that the arguments presented in the foregoing paper are his individual opinions only. He is not acquainted with the views of tiny other officer upon the subjects treated, except as he has seen them expressed in official reports or in the public press. a It has even been hinted by high judicial authority that the reclamation act itself would not stand the test of constitutionality, if brought into court. FOREST LANDS FOB THE PROTECTION OF WATERSHEDS. 103 THK EQUALIZING INFLUENCE OF FOKKSTS ON THE FLOW OF STREAMS AND THEIB VALUE AS A MEANS OF IMPROVING NAVIGATION. [Being mainly a rejoinder to the paper of Col. H. M. Chittenden, U. S. Army, entitled " Forests and reservoirs in their relation to stream flow, with particular reference to navigable rivers," presented before the American Society of Civil Engineers. Prepared at the request of His Excellency Curtis Guild, jr., governor of the State of Massa- chusetts, by George F. Swain, LL. D., professor of civil engineering in the Massachusetts Institute of Technology.] It is the opinion of probably the great majority of engineers conversant with the subject, that forests act as equalizers of the flow of streams by diminishing, in general, the frequency and violence of freshets, and increasing the low-water flow, and by preventing the erosion of the soil and the consequent silting up of water courses. Based on these premises, it is believed to be of much importance to the inter- ests of navigation as well as to other interests, that the United States Govern- ment should establish forest reserves in the Southern Appalachian and White Mountains, the object of such reserves being : First. To aid in the protection of certain given watersheds. Second. To enable the Government to give an object lesson to private owners in the vicinity as to what may be accomplished by proper forest management, and to cooperate directly with such private owners in encouraging them to use the best methods. Third. To aid in preventing forest fires and the consequent deterioration of the soil and destruction of timber on both government and private lands. Fourth. To aid in and encourage reforesting, and by this means and by proper management to augment and prolong the timber supply. In September, 1!)08, a paper, the title of which has been quoted above, was published in the Proceedings of the American Society of Civil Engineers by Col. H. M. Chittenden, of the Corps of Engineers, U. S. Army, in which argu- ments were advanced which in a measure seem to controvert the generally accepted opinions. The present paper is a brief rejoinder to that article, pre- pared with special reference to its bearing upon the Appalachian and White Mountain Forest Reserve bill. The paper of Colonel Chittenden is exceedingly well written, and upon first reading might seem to contain strong arguments against the regulative action of forests. Upon analyzing its statements, however, it will be perceived that Colonel Chittenden practically acknowledges most of the claims made for forests, that the paper contains many contradictory assertions and illogical deductions, and that his arguments are largely conjectural and unaccompanied by proof. The paper states that the commonly accepted opinion is that forests have a beneficial influence on stream flow (1) "by storing the waters from rain and melting snow in the bed of humus that develops under forest cover * * * preventing their rapid rush to the streams and paying them out gradually afterwards, thus acting as true reservoirs in equalizing the run-off; (2) by retarding the snow melting in the spring and prolonging the run-off from that source; (3) by increasing precipitation; (4) by preventing erosion of the soil on steep slopes and thereby protecting water courses, canals, reservoirs, and similar works from accumulations of silt." This will probably be admitted to be a fair statement of what the believers in the benefits of forests consider to be true, except that some do not consider that there is yet sufficient demonstration that they increase the rainfall, and also except that the water is not stored simply in the bed of humus, but also in the ground beneath. With reference to the first of these points, the author states that it is " strictly true of average conditions." He says : " It is true, therefore, as popularly under- stood, that, in periods of ordinary rainfall, with sufficient intervals for the forest bed to dry out somewhat, forests do exert a regulative effect upon run-off. They modify freshets and torrents and prolong the mn-off after storms hav
