"John Hays IL\mmond: "Please say to Joint Engineering Societies that I am greatly gratified to know of their co-operation in the movement for the con- servation of the natursll resources of the country. The members of these societies with their technical knowledge are not only better advised as to the necessity for such conservation, but are more com- petent to suggest the methods by which such conservation can be carried out. I have already pledged the Administration to as full support as possible of the policy, and I am glad to renew my expression of sympathy with the movement, and to state my high estimate of the value of the aid which can be rendered by the United Engineering Societies. "Wm. H. Taft.'' ^ff/S-7^ INTRODUCTORY ADDRESS. Dr. James Douglas. I am very sorry to say, Ladies and Gentlemen, that I am a sub- stitute. Mr. Bates, President of the American Society of Civil Engi- neers, wishes to express his regret, regret that I know you all appre- ciate, that sickness at home obliges him to be absent. I can only feel confusion at having to fill his chair, and yet not fill his place. It is a, pleasure to us all as engineers of different schools to meet in a common cause, for it brings home the proof of our mutual dependence. Every advance in technical science and practice is made through the co-operation of two or more of the branches of the engi- neering fraternities. The miner and metallurgist are always more or less helpless without the aid of the mechanical engineer, and now both must call in the electrical engineer to their assistance if engaged in work of any magnitude. In one endeavor, however, we are all united, j* that is, in trying to utilize to the utmost Nature's resources; for our ^|» business is to handle Nature's raw material, and convert it into more or less refined and specialized compounds and forms. In so doing, we are learning more and more how to avail ourselves of Nature's forces. By the very virtue of our work as we study the properties of matter, we '; are driven to employ as little material and as little energy — whether' our own or Nature's — as will serve our purpose, if for no other reason' than that both material and energy cost money. Ever since the great revival of industry, therefore, three-quarters of a century ago, engineers, whether mining, metallurgical, civil or mechanical, have combined in using their best skill and most com- petent efforts in the direction of saving — not of wasting. That they have not succeeded in reaching the ultimate consummation of recover- ing everything and losing nothing is not their fault. They have, how- over, always seen a practical goal ahead of them, and their efforts have been unanimous and strong to reach it. I have said that some or all branches of the Engineering Profession have had to combine to attain even the success which has been as yet reached. Take what might be considered a purely metallurgical problem such as that which Sir Henry Bessemer succeeded in solving when he perfected the pneumatic method of making steel. The chemical and metallurgical principles involved had been thoroughly understood. It was only by bringing his mechanical knowledge, skill, and ingenuity to bear upon his experiments that he succeeded where others failed. That the method was carried out, on this side of the Atlantic, on so much 399152 4 INTRODUCTORY ADDRESS more vigorous a scale than abroad was due more to the brilliant genius of Holley as a mechanician than as a metallurgist. The same is true in every great advance made in the field of metallurgy. The improve- ments in iron blast-furnace practice have been due more to the engineer than to the metallurgist. A glimpse back in any direction will show that the engineer has not been guilty of knowingly and wilfully wasting. Of the two sub- jects that seem to distress the public mind most at the present time — the destruction of our forests and the supposed wilful waste of our fuel — the engineer can be held responsible for only the latter. The subject of forestry may be considered as more within the domain of the agri- culturist than of the engineer. I have not very clear ideas with regard to forestry, nor do I think that most of the people who preach upon the subject could carry their precepts into practice, if called upon to do so. Considering that our forests have all been largely stripped of their best trees, we have not seen any feasible scheme proposed by which scientific forestry on a large and profitable scale can be applied to the recovery of what remains uncut. Apart, however, from re- forestation, there are many defects in our lumbering system which call for stringent remedies. But with regard to the waste of coal underground, as mining engi- neers we have to do. For the waste of heat and the power-giving prop- erties of coal above ground, the civil and mechanical engineers are more or less responsible. I think, as a mining engineer, that the , |/ question of waste is one that must be considered relatively and not \j) absolutely, and mining waste, therefore, opens up a very wide and ' debatable field of controversy. But I am sure that when we look back upon the last three-quarters of a century, we must be struck with the immense advance that has been made, through the co-operation of the metallurgical and mechanical engineers, in saving fuel. The old blast furnace used to consume 37 cwt. of coke per ton of pig-iron, the modem one consumes less than 20. This saving alone on our present produc- tion of pig iron, assuming that a ton of coke is made from If tons of coal, approximates 40 000 000 tons of coal. This saving is due in great measure to the utilization of the waste gases in the heated blast; but the waste heat over and above that consumed in the hot blast stoves is sujficient to generate the steam of the blowing engine and leave a surplus for running the rolling mill. And, not satisfied with using up these waste gases, the metallurgical chemist in some instances is endeavoring to extract their chemical ingredients from the gases before utilizing their combustible properties. The saving, therefore, of coal within the stack itself is only a part of the total saving under modern blast-furnace practice. The Bessemer process eliminating the direct use of coal in the converting of pig iron into steel, and the use of gaseous fuel in the open-hearth regenerative furnace, probably repre- INTRODUCTORY ADDRESS sents an annual saving of another 20 000 000 tons of coal. The fuel saved by generating electricity and distributing it to our great rolling mills, and thus dispensing with the innumerable small steam and power- generating plants throughout the works, must add several millions more to ur credit. What, therefore, the consumption of coal would be, had not the wits of every branch of the Engineering Profession been exer- cised in trying to save, it is appalling to contemplate. But when we turn to pure engineering and take what has been saved by the quadruple expansion cut-off engine as against the old slide-valve engines of not over a generation ago, the old engine burning from 5 to 7 lb. of coal per horse-power as against 1^ to 2 lb. in every modern engine of good design, we have a further saving of almost an in- credible amount— certainly not less than 40 000 000 or 50 000 000 tons of coal a year. And yet neither in the blast furnace nor in the best- equipped boiler and steam-engine plants is there an approach to recov- ering the full equivalent of the heat. While, therefore, I think we need not be seized with serious compunctions of conscience for not having endeavored to save this important item of the natural resources, no class of men is so keenly conscious of what remains to be done as the members of the engineering fraternity. If the figures given in Mr. Lewis' recent articles on fuel and its future be correct, a steam engine consuming 2 lb. of coal per horse-power hour is utilizing only 8.6% of the heat efficiency. But when we find that the Diesel engine, using mineral oil, is giving off 32% of the heat efficiency, we are stimulated to try and perfect an engine which will utilize fuel to better purpose than the existing steam engine, and to look forward to the day when at least 50% of the total calorific value will be converted into mechanical energy.* It is not only in the matter of coal consumption that the engineer is succeeding in making economies ; it is in the quantity of every mate- rial that he handles. Our civil engineer in this country, relying on the accuracy of his estimates of stresses and strains, has cut down the amount of iron and steel put into our bridges or into the skeletons of our large buildings almost to the very limit of safety, and some- *CosT OF Fuel for the Production of 1 British Horse-Power Hour.

The dread of wasting has been even stronger than the dread of endangering human life. Then again we have the metallurgist and chemist at work, en- deavoring to discover methods by which useful metals can be produced from the substances of the earth's crust, which exist in incalculable /quantity — such as aluminum. Admitting that we are using the com- i moner metals with all the prudence and economy that can be devised, we are consuming them at a rate which within a calculable period must make them costly. The Engineering Professions, therefore, are working together toward discovering, manufacturing, and then apply- ing either new metals, new alloys of the metals, or new mineral com- . pounds, with the object of finding a substitute in a cheaper metal ' for a costlier one, in a more durable metal for a more destructible one, or in an incombustible substance like concrete for inflammable timber. The rarer earths are being made into mantels, in order to increase the light generated from the same quantity of gas and thereby to save fuel. You will be told by Mr. Stillwell what the electrical engineer has done in the conservation of energy, and perhaps he may be courageous enough to prophesy what the electrical engineer may yet do, but that is a subject upon which the imagination may run riot. It is clear, therefore, that if any body of men is free from the crime of having wilfully or carelessly wasted the national resources, they are the engineers of the four great classes, a representative of each of which will address you this evening. They, from their accurate knowledge of the subjects on which they talk, will prescribe saner remedies for the evils — whose existence they will be the last to deny — than either the t>oliticians or the irresponsible, anonymous writers in the public press. THE CONSERVATION OF WATER. John R. Freeman, M. Am. Soc. C. E. I have been given, this evening, twenty minutes in which to speak on the Conservation of Water. How can we best spend this time? The conservation of water for Municipal and Domestic Supply, for Irrigation, Navigation, Power, Industrial Purposes, and for Scenery, are all interesting topics. The logical starting point for study in each case is the water that falls irregularly and intermittently from the sky, and conservation begins with its detention and storage in snowbanks, leaf mould, porous earth or surface reservoirs, and we should particularly study the most important of all reservoirs, the porous upper strata of the earth. It is plain that in the time allowed we cannot go deeply into any one of these subjects, nor is it the purpose of this evening to present treatises. Perhaps in this audience of engineers we can best use some of this time in promoting discussion on certain misapplications of the doctrine of Forest Influence upon Stream Flow and one or two other features of the conservation movement that have been urged with more attention to making an impression than to scientific truth. Lumhering and Stream Flow. — It has been broadly stat€d that the cutting off of the forests in our Eastern mountains has increased the floods, intensified the droughts and greatly injured the water power of our rivers. I challenge those who so loudly make these statements to produce proof! The broad truth that forest cover in the mountains is beneficial for conserving and regulating stream flow and preventing soil erosion, is too firmly established to be shaken, and the work of reforesting and fire guarding should be pushed with tenfold the present vigor, but nevertheless, let us as engineers caution some of our good friends to be more careful in their applications of this doctrine. To be more specific, the statements that lessened summer flow, greater floods, or the shoaling of channels, because of deforestation, have come to the water powers of the Merrimack or to the navigation of the Hudson, rest on fancy and not on fact. It is my belief, based on many years' observation, that the lumber- ing and the clearing for agriculture that have been going on in these Eastern mountain regions for the past hundred years have not measur- ably affected the flow in flood or drought of any important rivers of the Wliite Mountains or of the Adirondack region, and probably not of those of the Southern Appalachians. 8 THE CONSERVATION OF WATER I was born almost within the edge of the White Mountain forests, was for ten years engineer with a water-power company on the Merri- mack, and have had occasion to study stream-flow conditions carefully in certain parts of the Adirondacks and in the heart of the North Carolina mountains. The daily flow of the Merrimack probably has been observed with precision for a longer period than any other large American river, and these precise measurements reveal no progressive increase in intensity of flood or drought and no decrease of average flow. Why should they ? Traverse the highways and climb the hills and esti- mate the percentage of cleared land. You will find it surprisingly small. Note the abandoned fields and pastures that have grown up to woods. It takes 40 years to grow a good pine, and from 100 to 200 years to grow a good stock of spruce timber, but go where the lumberman has been but five or ten years ago in these Eastern mountains and see how soon the scars that he left are healed. There are some small regions of speciar sterility where the fire has followed him and made a deeper scar, but the percentage of area in these is small. The sprout land is nearly as efficient as timberland for stream flow. The cutting out of scattered merchantable spruce, hemlock, balsam or pine, from among the large hardwood growth, as I have observed it in the heart of the Adirondacks, can make no very material change in the melting of the snow or in the rapidity with which the rainfall reaches the river. In these particular regions. Nature frowns on agriculture and there can never be the broad denudation and change into bald prairie that we find, for example, in the Genesee Valley, and the more of thrifty hardy farmers in the mountains, the less chance that forest fires will run riot, and destroy the sponge-like humus which it may have taken hundreds of years to accumulate and which promotes the forest growth. I beg you not to misunderstand me. There is no more earnest lover of woods than I; no one more profoundly appreciative of our new national forest service, for I have seen its working in the Sierras and have seen the need of something like it in many places elsewhere. I would rejoice to see established a great forest reservation in the White Mountains; another in that glorious "land of the sky" extending northeast from Asheville and surrounding Mt. Mitchell, monarch of the Southern Appalachians; and I rejoice in the extension of the grand Adirondack park so well begun by this Empire State, and in a hundred smaller forest preserves like those so wisely established by Greater Boston in the Middlesex Fells and on the Blue Hills of Milton; but let us not in our earnest advocacy make claims in their behalf which do not rest on the engineering basis, the simple truth. I have welcomed the recent paper by Colonel Chittenden* on this __ * Transactions, Am. Soc. C. E., Vol. LXII, p. 245. THE CONSERVATION OF WATER 9 subject before the American Society of Civil Engineers for its timely words on the obverse of this question of forest influence upon stream flow, although I do not concur in all his views. One frequent error has come from a failure to differentiate between different conditions of climate and porous soil, and to make too specific an application of what may be true on the average. The statements regarding the Merrimack and the Hudson which I have criticised as without foundation in fact may very likely be true of some drainage areas in a more arid region. Forests, Fires and Lumbermen,. — Time does not permit me to go into this subject of forest influences as I would like, but from the remarks already made I desire to draw out two texts and say a little on each. The first is on the present sinful encouragement of forest fires. I spent a little time a few years ago in what is i)erhaps the most magnificent forest in the world, on the western slope of the Cascade Mountains back from Seattle. One day I literally climbed through the forest primeval, up and down over the trunks that had fallen, some perhaps a century before, treading much of the time on a deep yielding cushion of green moss and humus that it may have taken several centuries to accumulate. Another day I witnessed the new methods of lumbering by means of railroads and winding engines and steel cables, and saw the waste tree-tops and brushwood left in such loose disorder as to invite fire when the sap should have become dried out a few months later. Another day, and by night, I saw fire eating into just such a tract, that had been left by the lumbermen the year before, and later I walked over the mountainside left so naked, so rocky and so sterile as a result of this fire, that it seemed that another such forest on this ground could never get a start. Fortunately, this area thus swept was not very large. A lumberman of exceptionally wide experience tells me that he has experimented on the cost of lopping down and piling the tops and burning them under supervision, after they had become seasoned and while the surrounding ground was moist, and has found all this added only about 25 to 50 cents or, in some cases, Y5 cents per 1 000 ft. B. M. to the cost of his lumber in the pineries of Minnesota. In a brushy country or in the dense woods of Washington it would cost much more. The question is, does not the benefit to posterity warrant this tax ? We ought not to be too hasty in answering, but one who has tramped over a recent burn will be inclined to say "Yes," and that the action of the lumbei*men which leads time and again to this result should be made a crime with penalties that would deeply touch the sensitive pocket nerve." Accuracy of Stream Measurement. — The second of the suggestions, growing out of my previous remarks, is a plea for stream-flow measure- ments of greater precision, through which we can more accurately 10 THE CONSERVATION OF WATER appraise the worth of waterfalls and reservoir sites for development, and, in the slow course of time, can obtain som.e more precise knowl- edge of the effect of forests upon stream flow. I have again and again testified to the utility of the hydrographic work of the U. S. Geological Survey, and so I will hope for pardon in pointing to places where it could be made more useful and in urging that if half the stations were abandoned and the accuracy and pre- cision all through the year doubled at the remaining stations, under some keen traveling supervisory engineers who could teach the in- experienced hydraulicians, whose employment is compelled by the im- portance of covering many stations with a scant appropriation, how to measure the flow in the ice season, how to set traps for errors of observation, and who could arouse a pride in completeness and pre- cision of measurement, while the central office is putting emphasis on intensive work instead of nearly all its emphasis on extensive work; then, after a while, by comparing districts of similar rainfall and topography, and substrata, wooded and unwooded, or before and after close cutting, we could get' some precise information on forest influences. Eor this kind of work we must rely on the general government, and it is so technical and has to be so painstaking and so long-continued that it is hard to make congressmen understand its worth. I have had many opportunities, East and West, for coming in contact with the hydrographic work of the IT. S. Geological Survey. From the start it has been carried on by men of high ideals, trying, under scant appropriations, to satisfy the demands of hundreds of localities, and not- withstanding that one has to be on the watch for errors, their records are of profound value, and I know of no one way in which the good cause of the conservation of water can be more advanced than by helping this department to secure from Congress an appropriation com- mensurate with the value of its work for present and future, and then let us insist on it giving us the results of more intensive and more precise and more careful work. Water-Power Conservation. — The conservation of water for power development is a topic on which I am expected to say something. My theme is in a field of more cheerful prospects than those assigned for this evening to my brothers, who have to contemplate the early exhaus- tion of the world's stores of coal and oil and iron, for the hydraulic engineer bids fair to flourish for some thousands of years after the builders of steam engines and gas engines have vanished from the face of the earth. As matters stand to-day he has less urgent need of having conserva- tion preached him than those who work with other sources of power. His turbines yield 85% of the ideal, and there is small hope of ever attain- ing a higher per cent, of useful effect than Uriah Boyden obtained THE CONSERVATION OF WATER 11 sixty years ago on the Atlantic Mills turbines in Lawrence. The progress since that day has been chiefly in conserving the labor of the machinist who makes the turbine. Sixty-five years ago, Storrow, in planning the power development at Lawrence, Mass., conserved the full measure of the opportunity in a way that could hardly be excelled to-day. But Storrow was the best educated engineer of his day, and Boyden was a physicist whose insight and skill would be honored in any of our modern research laboratories, and these works were pinnacles of achievement, not appreciated or copied broadly through the land. Nevertheless, the chief rivers of New England, through plants tliat were mostly designed half a century ago, are to-day yielding nearly as much power as they could yield under ideal conditions, and they pre- sent no such margin for improvement as is presented in the manufac- ture of power from coal. Here and there are a few opportunities for larger storage of flood water, or for storage of water that now wastes over the dam at night, and in a few of the older plants there is some needless loss of head. The chief error of design, judged by standards of to-day, was too great a subdivision of the fall. Two or three plants under low head have been built where one plant under a high head would have been better, and too great subdivision into small scattered units has been made. The cost suffered more than the efficiency. It was conservation of capital, not of water, which failed. Turbine Efficiency. — ^In the water-wheels themselves a slow process of survival of the fittest has long been going on. This was stimulated in the early days by "The Lowell Hydraulic Experiments," later by tests at Holyoke, and in recent hydro-electric times it has been further advanced by tests under working conditions in which the power has been measured by the electrical apparatus. Thus it happens that to-day the country grist mill can buy a turbine of YO or 75% average efficiency from half load to full load, made chiefly in the foundry, at surprisingly low cost; or the great hydro-electric plant can readily procure a specially designed 5 000 or 10 000 kw. unit that will run close to the theoretic limit of efficiency. These possibilities are not always taken advantage of. The builder of the stock turbine is sometimes more sound in his machine-shop prac- tice than in his hydraulics, and he not infrequently throws away 5 or 10% of the useful effect by crowding twin wheels toward a common draft tube, or by crudely trimming the blades of the runner in fitting a stock pattern to a special need, and in nine cases out of ten the mill owner has no means for measuring within a margin of 10% error, either the second-feet of water applied, or the horse-power derived, and therefore no means of proving the turbine efficiency within about 20 per cent. Not long ago I made tests of representative units in a hydro-electric plant of 40 000 h.p., where the turbines were wasting 12 THE CONSERVATION OF WATER about 15% of the power of the water through faulty design, largely due to lack of adaptation of speed of revolution to the existing fall, and I have seen in high-head plants of the Pelton type, on the Pacific slope, a grievous waste going on, due partly to defects in adaptation of lay- out to a variable load, to unnecessary friction of water in the conduits and approaches to the nozzle, and to wasteful methods of speed regu- lation by deflector nozzles. Such conditions are not the rule and all these matters of water-wheels and lay-out of plant are in a state of active evolution and their full measure of conservation will soon be "secured. Inducements for Developing Water-Poiuer. — Throughout the length and breadth of this land, capital has commonly been ready, and some- times too ready, to build dams and put in turbines wherever there was reasonable expectation of an ordinarily good rate of return. Until the marvelous electrical developments of the past ten or fifteen years, great water-power developments were commonly great disappointments to those who put in the money. At Lawrence, Mass., one dividend was paid on expectations, the next twelve were passed on the facts. The original shareholders at Holyoke, Mass., Lewiston, Me., and Cohoes, N. Y., lost most of the money they put in. Our English friends and others who buried their millions at Massena, N. Y., would be pained to relate the discount at which they sold out, and there are to-day certain magnificent structures languishing half built on the Susquehanna and the Yadkin, where an investor with some spare millions would be very welcome. More than one street railway or factory has found disappointment in the variable flow of a river and, after liberal expenditure, has come to a realizing sense of the trouble ^ and expense of providing auxiliary power. y f^C~~I mention these examples because I have noted in some of the recent \ conservation talk an idea that the flow of almost any river or stream I of rapid descent could be easily transmuted into a never-ending flow \^ of gold. ^^^^^^"^ Glowing estimates, some of them from the government officials, have valued undeveloped horse-power to the extent of millions on millions of horse-power, at $20 per horse-power, which is about the current selling price for electrical power in the given locality after it has been developed and after delivery over a long transmission line, and have failed to remark that $100 per horse-power, or, including transmission, perhaps $150 in hard cash had first to be added to each of these resources of Nature before it was worth anything at all, and that on top of this capital account there must be added operating costs and business expenses. Also, opportunities for vast storage reservoirs have been tabulated, and their great potential value pointed out, but with no adequate sug- gestion as_to the feasibility or cost of the dams, or the possibility of THE CONSERVATION OF WATER 13 such gradual silting up of storage space as is experienced on many- Southern rivers. The same glowing accounts fail to discover what use could be made of such vast amounts of power in these remote localities, and they utterly ignore questions of market in reckoning value. Kidicule and distrust are the proper reward for those who put forth these unqualified statements. True, there are processes coming over the horizon for deriving a stock of nitrogenous fertilizer from the air by means of hydro-electric power, and the production of tool steel, perhaps twice as good as the best that our arts yet know, from the electrical furnace, and we have foundations for a faith that electro-chemistry has other wonders in store; but these uses are yet here only in small degree. Let us have less rhetoric and more precise engineering investigation in estimating the extent and value of these great resources. Practicable Water-Power Conservation Methods. — The Secretary of one of our National Engineering Societies has urged that in this brief talk I make some recommendations for action. The plan of action which will accomplish more good in water-power conservation than any other of which I can now conceive is that adopted by New York State two years ago under the wise initiative of Governor Hughes, and carried out by the State Water Supply Commission. Ac- cording to this, each State should collect the facts regarding each of the notable opportunities for power development within its borders, select the important ones for survey in detail after careful recon- naissance, prepare an outline plan for each, with all the detail that would be required in the preliminary studies for actual development, with full estimates of cost of plant and of amount of power available in different seasons of the year, and make these facts all matters of permanent public record, printed, and widely distributed. In these surveys the conservation idea should have full sway; measuring up the full engineering opportunity, with dams planned at the highest level and tail races at the very lowest level that the topography will reasonably permit, and with storage reservoirs of the greatest height and area for which Nature has provided a reasonable location, up to the full measure of reasonable flood control. Every noteworthy opportunity for power development that will ever exist within the State can thus be soon placed on the map, and there will never be a more advantageous time than the present thus to take account of stock, so that present owner, promoter, and public can see just what degree of promise there is in each opportunity. The range of stream flow, in summer and winter, in extreme flood and in extreme drought, can soon be made a matter of certainty within narrow limits, and can be confirmed with greater precision from year to year by a system of daily gaugings, summer and winter, definitely planned in the beginning to cover at least a ten-year period. These 14 THE COXSERVATIOX OF WATEK estimates of stream flow can be best secured through co-operation with the hydrographic branch of the National Government, providing the qualities of precision, accuracy and care in its work, particularly in times of ice obstruction and in drought, can be improved. The State can perhaps wisely go further than heretofore and, at. some of the great sites, can itself construct the main works, much as the United States Eeclamation Service has built reservoirs and canals, or it can mvite private capital, through the removal of restrictive laws like those which now forbid storage reservoirs in the Adirondacks, or by laws helpful in bringing the full natural opportunity of one proper site under one control, like the "Mill Acts" and "Flowage Acts" of some of the States. According to conditions found, the State may, in one case, properly levy a special tax on the power produced, or in another case may best permit exemption from local taxation for a term of years, and in view of the limited number of these opportunities it should be the aim of the State to safeg-uard the future against ex- tortion through monopoly. There is already manifest in some parts of the country a tendency, under the new conditions of electrical transmission, for all of the power companies in a district to get to- gether in a sort of trust, and this may be followed later by rates not primarily intended to foster local industry. The State Should Foster the Local Use of Water Power for the Founding of New Industrial Communities. — ^By far the most beneficent policy of conservation of its water power that the State or the Nation can adopt is one which will tend toward this power being devoted to the founding of industrial communities, and that kind of industry is best which will bring the greatest population per horse-power and the most highly skilled class of operatives. The first step in such a policy of conservation is an accurate in- ventory and publication regarding each undeveloped or scantily de- veloped opportunity. I have spoken of the unfortunate early history of large water-power developments in this country. The marvelous development of electrical power transmission during the past fifteen years has greatly changed the conditions, and there are certain aspects of the case not wholly favorable to the best ultimate development of the country, which at least should be considered. The financial troubles that came to the early developments resulted from lack of income during the long period of waiting for customers for the full output. A fair interest return on a 10 000 h-p. plant could not be met from the rentals of 1 000 or 5 000 h.p. To-day electric transmission reaches out and markets the entire output immediately to customers now deriving their power from coal, and in many, cases this method of use has brought quick and generous profit, particularly if the promoter has cut out the tenderloin and left the rest of the THE COXSERVATIOX OF WATER 15 carcass to rot. It may be claimed that this kind of use has helped - to conserve our Nation^s coal supply and so is in line with the policy of conservation, but certainly it has not produced employment for more people and has not built up communities with hundreds and thou- sands of homes as did the older water-power developments at Lawrence, Nashua, Holyoke, Bellows Falls, and a score of other thrifty cities that were built solely because of a water-power development, or, as has been accomplished at the many thrifty towns built up in recent years where the Southern Appalachian rivers break over the edge of the Piedmont Plateau. Electro-chemical processes, now coming along fast, are destined to absorb cheap power in unlimited quantity, and these, unlike the machine shop or cotton mill which sets one operative at work for each 1 or 2 h.p., may set at ^work only one operative per 100 h.p. The statesman versed in political economy may well give some thought to these questions of power conservation in their broadest sense. Some are deploring the crowding of population to the great cities. T I Is it not within the proper scope of the conservation movement for the \ \ State to encourage not only the maximum development of each oppor- \ tunity, but also, by favorable legislation, to encourage its use in such j manner as shall found new industrial centers and provide employment / for the largest number possible? — ^ y Some Technical Details. — Coming down from these larger problems, there are many technical details which tend to the conservation of water, which it would be interesting to discuss with this audience of engineers, for example, the use of the "mass curve" or summation hydrograph, for studying the possibilities of various reservoir volumes in conserving the flow of the flood season. Something might well be said about the use of the surge tank on long turbine feeder pipes, for conserving water now wasted in speed control, and which permits the pressure tunnel with all its advantages in place of the open canal; we should discuss also the application of steam heat to the turbine, and the electrical warming of forebay screens, for conserving the output of power during the run of anchor ice on rivers in the extreme north; and we would do well to discuss means for the encouragement of con- tour plowing and planting by the farmers in those regions where storage reservoirs are prone to silt up. There are plenty of water-power topics which, viewed from the standpoint of conservation, might furnish interesting discussion for several evenings, and on the one important topic of relation of forests to conserving stream flow under different climatic conditions, the dis- cussion is far from being all in. But I must hurry on. Conservation of the Purity of Watercourses. — This, like the rela- tion of timber cutting to stream flow% is a subject on which it is time 16 THE CONSERVATION OF WATER for the engineer to interpose a word of caution in regard to some of til the well-meant talk that has been expended on this subject, which in j\;i\ conserving water seems to disregard completely the counterbalancing [ I y idea of conservation of capital. It is of first importance to arrive at a good sense of proportion in this matter, and to find, for various conditions, just what should be regarded as pollution, and it is important in following ideals not to take leave of common sense. The true criterion plainly is that no refuse should be discharged into a stream, which can do harm or cause offense in any important degree. It involves economic waste to set up standards of such purity as is needed for drinlcing water upon streams that can be given their greatest use as drainage channels. Flowing water, and quiet water in greater degree, have the power of digesting and rendering harmless very considerable quantities of street wash, and even of sewage, somewhat as the soil of our gardens renders harmless the manure applied, and, within limits, it is reason- able and proper to utilize the rivers as carriers or disposal agents and thereby conserve the funds which some small community can spend to its betterment in other ways. Some industrial wastes are thus digestible; others, like liquor from gas-works, are not. Some, if first subjected to a rough straining, or to brief detention favorable for bacterial action, may, under scientific oversight, be safely dis- charged into the natural drainage channels of the region. Others, like the washings from wool scourings, if in too large proportion will foul a watercourse most offensively, or, if it is discharged into a stream that soon mingles with the salt water of the sea, may become precipi- tated and cover the bottom with a filthy slime. The true problem of conservation is to study faithfully and patiently the needs of individual cases in the light of modern science, and learn how and to what extent the desired disposal can be carried on without harm or offense. The engineer is year by year coming into a more important rela- tion to the public as its trusted guide on some of its larger matters of welfare, and in order to maintain this confidence and gain still greater opportunity for doing good, he must not join in the shouting r^ until he has studied into the merits of both sides of the case and must I^Jhen be steadfast to common sense and to the truth. Conservation for Irrigation. — On this subject I have only time to say that no grander example of the conservation idea can be found than in the steadfast work of the past eight years of the U. S. Keclama- tion Service. Grand in conception, scientific in plan, faithful in execution, the world may, be challenged to show public service of a higher order. Recognition should be given also to the work of their contemporaries THE CONSERVATION OF WATER 17 of the State Agricultural Experiment Stations in showing how water saved from floods can be most wisely expended, and how one acre-foot, or less, of water can do the work formerly done by two. The recent call from Australia to our fellow member, Mr. Elwood Mead, to come over and help them, is a worthy tribute to the high standards that this branch of conservation has attained in our land. How remarkable the progress of the past ten years ! And how full of significance is the change to the community of interest idea and the development away from the wasteful methods and individual efforts of the early settler, who in many cases spoiled the chance for some- thing better by his crudeness of lay-out, or rendered ground soggy by appropriating more water than his need, or, from lack of storage, was without reserve for the days when the crop needed it most. We have passed pretty nearly through the days of unwarrantable promotions, of ditches and farms laid out on a scale for which water could be furnished less than one year in three, and of non-resident ownership in the reservoir and canal, and have arrived at the much better economic conditions of companies in which every shareholder farms his own ground. One development is following another so fast that irrigation bids fair to become within the next decade almost one of the exact sciences, and the spirit of progress and the idea of con- servation of water are now so active in the field of irrigation that the call for missionaries is not loud. It has, however, been suggested to me by one of my most active biological friends that there are inviting fields for experiment on the benefits of irrigation, much nearer than Colorado and California, and that the New Englander who has a field and a brook in proper topographic relation may find in orchard fruit and other intensive farming some surprising successes as a result of the conservation of this water in irrigation. Navigation. — What is done to conserve water-power will, in general, tend to conserve navigation. That there are grand opportunities for inland navigation in this broad land of ours, and that they will some day have an important part in our prosperity, with increasing density of population, must be plain to any one who has journyed down the Rhine and has seen it crowded with steamboats and barges, while railroads were busy on both shores. From the mouth of the Potomac to the Florida Keys, Nature has prepared the outlines of an inshore waterway which is little under- stood by those who have not cruised over some part of its waters. In this, boats may some day safely ply, sheltered from the storms of the Atlantic, and serve a region prolific in cotton and food supplies. That the Mississippi and its branches will some day again form great highways of commerce must be believed by those who are study- 18 THE OOXSERVATION OF WATER ing the signs of the times. A ship canal from the Great Lakes to the Hudson probably by way of Oswego will plainly be a demand of the future, and the true conservation of Niagara will be found in diverting much of the American half of this water into a great canal leading to ship locks and a great power plant at the bluff at Lewiston, by which the full 300 ft. of its fall will be utilized instead of as in the wasteful developments of the plants of to-day, in which only a fraction of this fall is of beneficial use. The future is full of great problems for the engineer upon these developments, and some of them are already up to us, lest obstructions be cultivated in the path of future progress. Scenery. — The remaining use of water needing conservation, among those which I have mentioned, is for purposes of scenery. In a majority of cases both power development and improvements in' river navigation will tend to add to and conserve the scenic value of the water. I have so little time left that I will only venture to call attention to some of the instances in which these values are combined, and which are so local, and present a navigation of such minor character, that they would be likely to fail of the proper recognition were they presented with the great National problems of waterway improvement. Nevertheless they are important for their suggestion of other oppor- tunities for similar beneficent work. One example is the beautiful Alster Basin at Hamburg, Germany, where a small dam transformed a broad marsh and shallow pool, with a small stream flowing through it, into a beautiful lake around which the best part of the city has grown up, and which serves the useful purpose of pleasure boating most admirably. This basin disproves the popular notion about stagnant water, for, although the flow through it is small, the quality of the water, which is of rather forbidding appearance at the entrance, steadily improves in the storage. The other example is a copy of the Alster now nearing completion on the tidal estuary between Boston and Cambridge, which will cover the un- sightly mud banks heretofore laid bare at low tide. Humbler examples, but also useful to the populous regions that they serve for pleasure boating, are the long slack-water basin near Eiver- side, Mass., formed by the Waltham Dam, and the water parkway now under construction in the Metropolitan district north of Boston, a route for pleasure boats and canoes, which is to connect a chain of lakes and bays and at the same time serve as the drainage channel of a great sanitary improvement. Clearing Power Reservoir Sites. — While the scenic value of water has received too scant attention in the work of the engineer, it is at the hands of the lumbermen and the early mill builders that it has suffered most. The dismal swamps, and the ghostly ruins of trees that THE COXSERVATIOX OF WATER 19 were killed by dam building in the Adirondacks and in Northern Maine, have made such raw spots in the memories of those of us who love the forest and its lakes that we sympathize wdth the purpose of the constitutional restrictions which this State of New York has inter- posed against the flooding of its forest lands by storage reservoirs. The same object, however, can be attained in a better way by reasonable laws and restrictions governing the clearing of lands that are to be flowed and limiting the elevation below which the lake to be created shall not be drained, and one of the taxes that any State may rightly impose upon water-power development is the proper clearing of lands to be flowed for storage reservoirs and a limitation as to the extent to which the bed of such reservoirs may be uncovered. A rigid standard may well be set. Stumps should not be left to pro- trude or to wreck boats as the water is lowered, and the clearing to a contour, say, 2 or 3 ft. above and 10 to 20 ft. outside the highest flow line will seldom impose a burden that the storage benefits cannot reasonably bear. An artificial storage lake will be commonly found to be a more beautiful and more wholesome feature in the landscape than a swamp, and, in most of our Northern regions where these would be built, the wave action will soon prepare a sandy beach along much of the shore line of the broader portions. THE CONSERVATION OF NATURAL RESOURCES BY LEGISLATION. R. W. Raymond, M. Am. Inst. M. E. The recent general awakening of public interest in the conserva- tion of national resources is an event for which, as engineers, we may ell be grateful. Even if we admit, as I suppose we must, that a part of it is artificial and another part erroneous or premature, and that some of the immediate purposes for which many have proposed to utilize it are questionable in character, the fact remains that a subject, to some aspects of which engineers have been for a generation calling attention in vain, is now suddenly brought forward in such a way that the sluggish sit up and listen, and the tremendous energy of public opinion is liberated by a swift reaction. How this energy shall be wisely directed is another question. The fundamental fact is, that without it nothing at all could be done; and it is better to have the will and the power, even to make mistakes, than to remain in sleep, knowing nothing, or in paralysis, knowing much, but impotent to act. "P*^" The official movement for the conservation of national resources 'did not, at first, contemplate the aid of the engineers of the country. I If I remember correctly, it was to be a convention of Governors and members of Congress. But, by a happy afterthought, the four national engineering societies were invited to take part in this convention, and, consequently, representatives from all of them were present. Their p"f"esence had little effect upon the conference, and, indeed, the confer- ence itself had little effect, except through the creation of a more permanent commission; the practical, though informal, commitment of the Governors of the States to the general movement contemplated; and the impression of a grand, unanimous advance in a new reform thereby produced upon the public mind. These results, however, were of incalculable importance, and may well be regarded as satisfactory to the friends of the general cause thus inaugurated. Concerning the attempt to utihze the results of this conference in support of certain measures in Congress, nothing need be said here. Such arguments were fair enough, to the extent of their real bearing, but they could not be conclusive as to questions involving grave considerations of constitutional power or political wisdom. It is not enough, under our institutions, to prove that a thing is a good thing and ought to be done, in order to establish the proposition that it should be done in a hurry, or in a certain way, or by doubtful means. l^.fyCUy<\ CONSERVATION BY LEGISLATION 21 It is a pity that the all-important question of conservation should be complicated at this early stage with measures of Federal legislation; but if that is necessary to secure discussion in the newspapers, and thus continue the interest and increase the intelligent comprehension of the public, the price is, perhaps, not too great. In this somewhat confused condition of an important movement, to which our engineering societies are sympathetically committed, what can we do as engineers to help, and not unnecessarily to hinder, the good work? Certainly, we ought to be able to do something useful; for the subject is one with which engineers as a class have been busy always. Much of the recent eloquence concerning it is merely the"^^ revival of what engineers have been saying for a generation; and their experience qualifies them to measure actual conditions and point out actual perils with special authority. ^ ' '>' ' I. What Is True Conservation? True conservation lies in the diminution, not of use, but of waste. v\/sy^,y^s,/^ The ingenious suggestion of John Mitchell, at the first Washington*\ \ Conference, that anthracite coal should be "conserved" by paying ' higher wages to the miners, so that anthracite would be dearer and \ people would use less of it, was the notion, not of an engineer, but of t' a certain kind of political economist. The natural diminution of con^^ ^ sumption due to the decreasing supply and consequent higher price of a given product is a result of free industrial competition, and cannot be wisely forestalled by any artificial means. It would be quite as rational and more practicable to delay the 1 exhaustion of supplies by restricting the increase of population— a f measure of legislation which has not been seriously proposed of lateT^ The fact is, that no legislation in either direction is called for. As regards the mineral resources of the United States, it may be confi- dently declared that the error of our pioneer miners and metallurgists was not that they worked prematurely and imperfectly, but that they too often left their low-grade ores, slags, and tailings in such positions as to be unavailable for re-treatment by their successors. But no legis- lation (even if the legislators had been wiser than the engineers) could have remedied this evil half as quickly or thoroughly as it has been remedied without any legislation at all. For the trouble was simply lack.jo£4Hiowledge. The moment the mine operator realized that his tailings were a part of his assets, to be turned into money at once, v ; either by himself or by a lessee, or by sale to a speculative purchaser ' with an eye on approaching improved conditions, that moment he began to preserve and protect them.* * See under this head the timely papers of Dr. James Douglas and John Birkinbine. Past-Presidents of the American Institute of Mining Engineers, read at the recent New Haven meeting. 22 COXSERVATION BY LEGISLATION Another illustration is furnished by timber conservation. Until within a few years the practice of forestry in our Eastern States by owners of small tracts and limited capital was impossible, because timber-land which was not within, say, five years of being ready for the axe would not command a greater price than cleared land. Regard- ing the forest as a crop which could be fully reaped in from thirty to fifty years, there was no market-value for this crop at an early stage. The cost of planting, nurture, and protection of the first ten, and most critical, years, could not be recovered by sale of the land through a corresponding increase in price. Being connected for some twenty years with the administration of large tracts of timber-land in Pennsyl- vania and New Jersey, I satisfied myself that, under favorable condi- tions, the investment required for replanting, training, protecting against fire, etc., for, say, forty years, would be returned, at the end of that period, with a profit of from 3 to 4 per cent, per annum. But this small deferred profit would not tempt even a philanthropist, especially since the larger part of the investment would be totally lost, if for any reason it became necessary to sell the land before the crop was nearly ripe. Legislation would not have- altered the situation; but something else has altered it — namely, the gradual increase in the market-value of the timber, and the corresponding perception of its value when only half-grown. Before long a tree-planted area in this country will advance year by year in cash value, in proportion to the money that has been spent upon it, and the condition of its growing crop. This will make forestry possible, and we shall have no more cause to fear the exhaustion of lumber than of corn. Meanwhile, with regard to our forest resources, even more than as to our mineral resources, it is waste rather than use that needs to be prevented; and the simple, adequate remedies are the pressure of economic conditions and the diffusion of knowledge. II. What Is the Best Method for the Prevention OF Waste? In my judgment, the progressive education of the people and the steady pressure of economic conditions will effect this result, as a general rule, better than any legislation can do it. The "debris decisions" in California, the many lawsuits regarding the damages wrought by furnace-fumes, and sundry other proceedings of that class, are not exceptions to this general rule, but instances of the application of the simple old common-law principle, that no man shall use his own to injure another's. The wrong may be remedied in law by a judgment for damages, or in equity by a judicial prohibi- tion. In either case, it involves no attempt to restrain individual freedom by legislation in the interest of economy, science or progress. COXSEKVATION BY LEGISLATION 23 Moreover, there is a large body of Federal legislation which does not form a clear exception to the rule stated above. I refer to the laws concerning the public lands. /Of these lands, the Federal Govern- nieirds both the 'sovereign and the owner, and it may and should do many things as owner, which it would not be right or wise to do as sovereign. It may regulate or forbid the consumption of the resources of its own lands; it may give them away, or lease them, or sell them, or work them on its own account, or simply hoard them, as a method of conservation. Some of these things might be foolish, but they are all permissible, so long as they do not interfere with vested rights and contracts.* j The manned in which our Federal and State governments have dealt with the natural resources over which they exercise not only sovereignty but also common-law ownership, may be supposed to give us some indications of their qualifications to exercise the larger powers which some are now urging us to confer upon them. This point will be considered below. For the present, I confine myself to the considera- tion of the part which governments play in the application of that remedy for waste of natural resources which I have characterized as the most effective. Without arguing as to the proper limitation of the functions of government, or pronouncing upon the validity of the ingenious distinction announced by Dr. Lyman Abbott, between a "paternal" government (which is traditionally a bad thing), and a "fraternal" government, which is a good thing, I may admit frankly that of all the extra-governmental functions the education of the people by the spread of inlorma'tibn " is'th'e most beneficial, the mosl~ potenET and tHe" least objectionable. Yet it is a mighty power, the exercise of which, under a representative democracy like ours, needs to be watched. For "government information" is clothed to the public eye with a special authority, which it ought to deserve. III. How Should the Government Information Here Under Con- sideration BE Prepared, Framed, and Distributed? I may mention under this head the following propositions, on which I think we, as engineers, ought to insist: Such information ought to ^ be: (1) collectedj with care, and n otjn a hurry; (2) stated_w^ithout bias ^, or argument in favor of this or that measure or policy ; and (3) made accessible to all who desire it — not by the wasteful and inadequate * The Constitution of the United States prohibits the impairment of the sacredness of a contract by any State, There is no such prohibition as to Congfess; and there has been of late a tendency in some quarters to argue that Congress may therefore do what it chooses to a contract. But the general course of our Supreme Court and the sentiment of the American people— which I believe to be still substantially sound in this respect— war- rant the view that the wrong constitutionally forbidden to an individual State cannot justly be perpetrated by the Federal Government. 24 COXSERVATION BY LEGISLATION system of giving to members of Congress so many copies per capita, but by^printing, iir"Sirccessive editions; tf "need l)e7 as many copies as individual citizens are ready to buy at cost. In all these respects, the masterly reports of the U. S. Geological Survey, including those on Mineral Resources, furnish models for imitation, and (if I am correctly informed) the forthcoming report of the National Conservation Commission is likely to be open to criticism. It will be a volume of 1 000 pages, prepared under Executive "hurry-orders" (for no other conceivable reason than that it might be transmitted to Congress with a special message by Mr. Roosevelt before he left the White House) by employees of the government already presumably loaded with the regular work pertaining to their positions. The contributions of many of these experts, even under these unfavor- able conditions, are likely to make the book highly interesting and valuable to engineers; yet it is uncertain whether copies of it will be obtainable, except by favor. This is an unfortunate beginning, which may, however, be forgiven if good results follow it. While I would not be guilty of the injustice of criticizing in advance the contents of a book which I have not seen, it is not unfair to criticize the use that has been made of it before publication in more or less "inspired" summaries and intimations which, taken together with the Executive directions under which it was compiled, give the decided impression that it professes to be an inventory of the natural resources of the United States, with an estimate of the rate at which they are approaching exhaustion. If this be the case, then the task imposed upon the Commission and its agents is one which could not be thoroughly or even tolerably performed in so short a period. And we may fear as a result that the report of the Commission will present macyjcru^^e and hasty "estimates," possibly rendered still more misleading by tabulation and graphic presentation, and the construc- tions of "curves," to be regarded as expressions of "laws." And there are some premonitions of an attempt to shock the public, and through the public, to startle Congress into immediate legislation, by "scare" head-lines, announcing that the supply of this or that material will be exhausted in so or so many years — ^the qualifying sub-title in small type, under the head-line, being, "If the present rate of increase in consumption be maintained"! Now, this is the one condition which will not be maintained, whatever happens; and people will not be scared by that argument. What is worse, they are likely, in their disgust, to refuse serious consideration of the really serious situation. I have heard of a man whose burglar-alarm roused him so many times by false warnings, that when at last it really rang for burglars, he put out his hand, shut off the current, silenced the bell, and turned over to sleep again, murmuring complacently: "You don't catch me this time!" CONSERVATION" BY LEGISLATION 25 And in this connection, I may add that when statistics are presented to support requests for special legislation, especially for the increase of executive power, they are doubly exposed to (perhaps undeserved) dis- credit * At all events, the mistaken use of such data is to be lamented as leading to a reaction that may go beyond the immediate case. Undoubtedly we can, as engineers, render most useful service by freely scrutinizing and criticizing the figures upon which all proposi- tions of reform, private or public, are professedly based. Others will always furnish the motive power of eloquence and enthusiasm. It should be our business to test the machinery and hold the rudder. IV. The Dangers of Legislative Conservation. These dangers are present in both State and Federal spheres, but they are greater in the latter, first, because the possible harm is more wide-spread; secondly, because the reform of any evils experienced is more difficult. Illustrations drawn from State action may therefore be regarded as bearing with double force upon Federal action. 1. Hasty Legislation. The first peril to be named is that of hasty and ill-considered action, taken under the influence of an ignorant though well-meaning public sentiment, roused or guided, in too many instances, by selfish interests. a. — The history of forestry in the State of New York furnishes a striking case in point. Sentimentalists who had gone no further in the knowledge of the subject than "Woodman, spare that tree!" and conceived of no more effective reform than a universal observation by the public schools of "Arbor-Day," were persuaded in the name of "Conservation" to carry into our new Constitution, with a rush and whoop of victorious virtue, a provision absolutely prohibiting all cutting of timber — that is, any exercise of forestry whatever — upon the I Forest Reserve of the State. At the same time, large sums were spent in the purchase of wild lands, to be added to the Forest Reserve — that is, to increase the area of State lands thus doomed to useless and mischievous decay. The constitutional prohibition was adopted by the Constitutional Convention against the urgent protest of the American Forestry Association, and was carried at the polls, with the rest of the Constitution, by the votes of those who assumed it to be all right, because it sounded so wise and patriotic. Moreover, there were amateur foresters in plenty, who learnedly expounded an "American" system, * See for an illustration the paper of Lt.-Ool. H. M. Chittenden, Corps of Engineers. U S. A., on ''Forests and Reservoirs in Their Relation to Stream Flow, with Particular Reference to Navigable Rivers," Transactions^ Am. Soc. C. E., Vol. LXII. p. 245. In this paper the author deals incidentally with the theory that the cutting of forests affects un- favorably the navigability of rivers— on which theory Congress has been recently asked so |/| to construe the Constitution as to extend the Federal authority over forests not on the \ public domain. ) 1 1 w 26 CONSERVATION BY LEGISLATION pursued by Nature, who would take care of her own forests, if we only let her alone. The necessity of such a jungle in the Adirondacks to protect the water-supply of the Erie canal, to conserve water-powers, and to furnish fresh air to invalids, was eloquently set forth. Above all, the wickedness of corporations engaged in actually using the whole forest-crop from one area after another — turning even the little branches and twigs into paper-pulp, and such-like odious products — was rhetorically set forth to a sympathetic and credulous public. Much of this lamentable performance was doubtless sincere; but behind the ignorant sincerity there was an influence which finally made itself recognized as well as felt — the influence of individual owners of small pieces of land, and summer residences thereon, who were determined that the State should preserve at public expense an unbroken old- fashioned wilderness around them — a wilderness in which they could camp or fish or shoot one another by mistake, without being disturbed by the sound of the axe or the saw. To this party, the thing to be conserved was a great open-air sanitarium and game-preserve, with incidental attractions of "scenery," unmarred by any unesthetic, be- cause useful, touch of man. The whole history of the matter has never been clearly and connectedly told; indeed, it is not yet ended. But among its unhappy results have been already the arbitrary destruction, through the veto of an ill-advised Executive, and at the dictation of interested parties who knew more, of the foremost forestry school of the United States ; the abandonment, upon false pretenses, of a forestry experiment, outside of the State Forest Reserve, which, if suffered to continue, would have furnished an object-lesson of incalculable value to private land-owners as well as official bureaus everywhere; and the surrender by the State of New York of its proud position at the head of the great work of the conservation of forest-resources for an ignominious place at the tail of that procession of progress. I say "at the tail," but perhaps it would be more accurate to say that New York is out of the procession altogether; for I do not think that any other State, however backward in popular intelligence, has ever gone quite so far as to forbid forestry upon its public land. But this is not all. The constitutional prohibition of all cutting of timber on the State Eorest Reserve has directly stimulated the setting of fires on that domain. The private owners of large timber- tracts have long been aware that, especially when they cannot afford to maintain a vigilant supervision, and therefore leave their forests to "the care of Nature" only, Indians and squatters deem it legitimate to start fires in the woods, for the sake of the subsequent new under- growth, which will furnish good food for cattle. Probably these fires are not intended to destroy the trees themselves; frequently (if I may judge from the singed trunks in many a forest which I have traversed), they do not have that result. But there is no doubt that they originate CONSERVATION BY LEGISLATION 27 many of the devastating forest fires ; nor is there any doubt that possible conscientious scruples on the part of the incendiaries are largely quieted by the argument that the woods are not specially valued by their owners, because they are not guarded. In this respect, the U. S. Forestry Bureau has wrought a great public benefit, by simply showing that the United States thinks its forests worth protecting. And this proof is mightily enforced by its actual utilization of the forest-products. But the State of New York, through its Constitution, practically blazons the boundaries of its Forest Reserve with the notice: "The timber on these lands is never going to be used!" Is it any wonder that people should think there is little harm in hastening somewhat the natural destruction to which it has been thus doomed by law? And unfortunately the hypothetical notice I have quoted carries, in practice, a portentous postscript, substantially saying that while the State will neither cut, on its own account, nor sell to purchasers the right to cut, any timber on the Forest Reserve, yet burnt and fallen timber may be removed! Could there be a more fatally seductive temptation to incendiaries ? In fact, apart from the unlawful character of the act itself, the perpetrator of it might easily convince himself that he was thereby doing the only thing which the folly of the legislators had left to be done, for the stoppage of irreparable waste of the natural resources of the State — namely, converting them by partial combustion into the only form in which they could be legally utilized ! Meanwhile a State Commission has gone on adding by purchase or otherwise to the Forest Reserve. But since the Constitution forbids the subsequent cuttting and sale of timber from any tracts thus pur- chased, after the title has passed to the State, the Commission cannot afford to buy timber-lands at prices including any value assigned to the timber. Consequently, it bargains for such lands, to be delivered to the State after the timber has been cut off, within a limited period, by the present owners. And the present owners, unless they happen to be within market-distance of a wicked pulp-mill, cut the salable timber as fast as they can, and turn over to the State the land with the un- salable underbrush, tops, branches and twigs of the forest — an ideal nursery of forest-conflagrations. The final result of all these attempts at conservation by legislation was exhibited last year, when the City of New York was darkened for many days by the smoke from the burning of hundreds of square miles of that Adirondack wilderness which had been prepared by igno- rant legislation to nourish just such a bonfire. The destruction of property thus occasioned was so great that one is tempted to wish our Constitution-makers, Legislatures and Governors had let the whole business alone! 28 CONSERVATION BY LEGISLATION Yet the tragedy has its comic after-piece. For our State authori- ties are now resuming on the Forest Reserve the once-ridiculed policy of tree-planting, instead of leaving the matter to Nature; and we hear complacent statements of the hundreds of thousands of new trees which have been set out. Yet everybody knows, or ought to know, that these plantations cannot be properly managed hereafter without the use of "the forester's weapon," the axe, and that when, at great expense, they shall have been brought to the condition of ripe, market- able forest-crops, nothing can be done with them, under our Constitu- tion, but let them decay, or sell them as burnt and fallen timber after "accidental" fires, and go on planting new ones! The alternative is to amend the Constitution — a slow and doubtful process — or else "con- strue" it so as to make it mean what it does not say — an easy and fashionable but most demoralizing expedient. h. — The mineral resources of the State of New York have received at the hands of its law-makers similarly ignorant treatment, under cover of which private interests have similarly secured unwarrantable privileges. Under this head, I will not enter into details here. My papers on the mining laws of New York* state a part of the case. But an over- ruling Providence has saved the State from the results of absurd legis- lation in this respect by withholding from it, so far as is now known, any considerable deposits of those minerals to which the most archaic, confused, impracticable and absurd provisions of its mining laws would apply. It is, therefore, not worth while to criticize these laws here, though they furnish minor illustrations of my general proposition. c. — In short, conservation by legislation has put New York in a pretty bad situation. Yet the people of New York are the best party to deal with it; and the way of remedy is the instruction of those people. If a similar set of blunders had been perpetrated by Federal legislation and administration, the case would be desperate, because it is almost impracticable to inform and rouse to action forty-six States concerning problems and perils which affect a single State only. d. — Such hasty legislation has characterized too often the course of the Federal Government. To take, for instance, the conservation of anthracite coal: In 1871, as Mr, Birkinbine has pointed out in his recent paper, cited above, the American Institute of Mining Engineers, at its first meeting, took up this question, listened to a paper by the late R. P. Rothwell on the unnecessary waste of anthracite in mining and preparation for market, and appointed a special committee on the subject, of which the late Eckley B. Coxe was chairman. Mr. Coxe might have been described as a "wealthy benefactor," being, with other members of his family, the owner of much anthracite land, the operator of extensive collieries, the lessor of many tracts and the of many others. Besides these qualifications for viewing the * Trans., Am. Inst. M. E., XVI, 770 ; and XXIV, 712. CONSERVATION BY LEGISLATION 29 subject from all standpoints, he was a thoroughly trained mining en- gineer — one of the foremost of his generation * Into the work thus committed to his leadership by the Institute, he plunged with char- acteristic generous ardor. As a means of making the results more effective, he secured the appointment of a Pennsylvania State Com- mission, the expenses of which, I believe, he personally paid, and the reports of which were printed by that State, at a time when the Insti- tute could not afford to issue such voluminous documents. In con- nection with this inquiry and the experiments which it involved, Mr. Coxe expended a large sum; but what he accomplished, with the aid of the colliery-proprietors, operators, engineers and "captains of in- dustry" who trusted and followed him, was worth many times that sum.f The waste of anthracite, when he began, was so great that less than one-third of the good coal in a seam mined reached the market. This waste was mainly due to two principal causes. The first was the demand for the larger sizes and the unsalability of the smaller sizes of anthracite, which caused the latter to be thrown away as without value. The remedy for this waste was to win market- value for the smaller coals, by instructing consumers in their use, inventing special devices for that purpose, offering these sizes at prices which made their employment profitable, and thus breaking down the old tradition and prejudice. To these measures were added remark- able improvements in coal-breaking and coal-washing machinery, which lessened the labor-cost of the operations involved, while diminishing, on one hand, the amount of fine coal and dust produced, and facilitat- ing, on the other hand, the clean separation of such useful material from the slate and slate-dust which carried it. The great saving thus effected cannot easily be estimated. Certainly the sentimental ama- teur or magazine writer who now traverses the anthracite-region and notes the big black culm-heaps as evidences of reckless waste, should take pains to ascertain the date at which each heap was accumulated, bearing in mind that all is not coal that is black, and that the culm- heaps of to-day represent, not an excessive waste, but the worthless refuse of a highly efiicient extraction. This great reform has been secured by the simple method of studying the facts and disseminating i the resulting knowledge in such a way as to bring to bear, through commercial conditions, the motive of enlightened self-interest, which \ is far wiser, as well as stronger and more potent, than ignorant and ; sentimental altruism. Legislation could not have helped it, but might ; have hindered it by limiting private enterprise. * See. for a more detailed statement of his life and work, my " Biographical Notice of Eckley B. Coxe," Trans., Am. Inst. M. E., XXV, 446 (1895). 1 1 would specially mention here the timely and effective volume of the Pennsylvania State Geological Survey, containing the Report on the Mining Methods and Appliances used in the Anthracite Coal-Fields, by Dr. H. M. Chance, another member of the Institute, Second Geological Survey of Pennsylvania, Vol. AC (1883). W vW\' 30 CONSERVATION BY LEGISLATION The second principal source of the waste of anthracite was the method of pillar-and-breast mining employed, or, more accurately, the way in which that method was applied. In laying out a given level, the breasts were made, say 20 ft., and the pillars 10 ft. wide — the theory being, that the pillars would support the roof during the exca- vation of the breasts, and that, when the breasts had been carried up to the level above, the pillars could be "pulled" or "robbed," and their coal recovered, as a final measure before abandoning that part of the mine. In practice, however, these narrow pillars were seldom or never recovered. They became crushed and worthless or not safely accessible, before the time of their extraction arrived; and it was cheaper to attack fresh coal elsewhere than to try to recover them. The remedy, of course, was to use another system of mining when possible, and, if the pillar-and-breast system was dictated by the conditions of the case, to leave wider pillars between the breasts, so that the coal in the pillars would remain in good condition and accessible for final extraction. It was easy to demonstrate this; but no amount of demonstration could bring about the needed reform, so long as the anthracite- collieries were generally operated under leases for periods of 15 or, at the most, 20 years, by lessees who paid royalty only on the coal actually marketed, and whose interest, therefore, was to market within the specified term the greatest possible amount of coal at the smallest possible immediate cost. As I remember the situation in the '70's of the last century, many of these short-term leases, taken under the inducement furnished by the abnormal demand for anthracite as a smokeless fuel for our blockading navy, were within 8 years or less of termination, a circumstance which put considerations of far-reach- ing economy out of the question. I remember well what Eckley B. Coxe said to me, that salvation for the anthracite-region and its store of natural resources lay in the control of the collieries by capitalists who had other aims than immediate profit from the coal; and that the acquisition of such control by great railway companies, whose interest it was to make anthracite the basis of a profitable freight-business for generations to come, was not only the best, but the only, remedy for the reckless and irreparable waste which the system of '^hogging" the mines under short leases had brought about. The results verified his prophecy. The great railway companies operating the anthracite-collieries have put more money into pre- ^ liminary dead-work and costly machinery; have been the pioneers of rational forestry, for the provision of permanent supplies of mining timber; have enforced economy in every department of production; have trained and employed the most skillful engineers and experts; in short, have redeemed from immediately impending rack and ruin the whole anthracite-industry. Incidentally, every one of them has continued at times to operate some of its coUeries at a mining loss, CONSERVATION BY LEGISLATION 31 rather than throw out worthy workmen, disarrange large transporta- tion-systems, and impair its plans for a permanent business. There are many collieries in the region to-day which would have to be aban- doned to-morrow if these companies were not permitted to operate them. Under these circumstances, what has the Federal Government done? It has enacted the so-called "commodity clause" of the "Hepburn bill," forbidding any railroad to carry its own products (with certain exceptions) to market. In other words, it has attempted to destroy the one agency that has proved itself able to conserve our anthracite coal. We are waiting from day to day to learn whether the U. S. Supreme Court regards this provision as constitutional. However that decision may turn out, it will not alter the folly of the legislation thus hastily and blindly enacted. 2. The Destruction of Individual Responsibility and Initiative. Human nature being what it is, we are all prone to order some- thing done which we think ought to be done, and then to feel that we have performed our duty in the premises. The result is an over- whelming multiplicity of laws with corresponding feebleness or sporadic irregularity in their execution, and, worse yet, a general disregard of the sanctity and authority of law. General intelligence is a law which executes itself. I need not argue this point further. We all know that the everlasting multiplication of statutes is a crying nuisance of our generation. And we must all agree that if any real or supposed evil can be cured by enlightening the public mind, it is folly to try to cure it by legislation, in advance of such enlightenment. 3. The Tendency of Governmental Agencies to Seek Additional Power. This is a natural consequence of the zeal and enthusiasm of honest public officials, for which they, ought to be praised, rather than blamed. Yet it involves dangers which need to be carefully watched. It is startling to observe that all the numerous departments and bureaus of our Federal government, with possibly one or two exceptions, have grown from comparatively small beginnings, and were never delib- erately planned for the wider spheres which they now occupy. This has often been the result of the forcing upon them of additional powers and duties — more often, I fancy, of their own laudable desire to extend their work. In most cases — ^particularly in the case of the IT. S. Geological Survey, with which I am best acquainted — we rejoice with pride in the result of the process; yet the process itself is a form of political "opportunism," against which we should be on our guard. By "opportunism," I mean the policy which takes a given step forward because the last step seems to require it, and without considering what ! > t5» CONSERVATION BY LEGISLATION may be the next step required by similar logic In this process, there seems to be no special point for "calling a halt," after the beginning has once been made; yet in many cases there must be such a point, if we could only find it; and I think it is our right and duty as engineers, in all questions affecting our own sphere of knowledge and work, to find the point and sound the warning. 4. The Expense of Governmental Agencies and Regulations. What is the purpose of "conservation," except to continue the supply of the materials needed to sustain and employ human energy? To spend money unnecessarily is to make somebody spend energy unneces- sarily. The famous anthracite commission (which, though vehemently declared to be a personal intervention only, was in form and effect a governmental one) permanently raised the price of anthracite coal 50 cents per ton. The infinite requirements of the Interstate Com- merce Commission are saddling an annual extra expense of many millions of dollars upon the railroads, and therefore upon the trav- elers, of the country. Hundreds of tons of useless monthly statistics, written or printed, are "filed" — that is to say, stored at Washington. The railroads of the country are employing an army of clerks, not needed before, to satisfy these clumsy and costly requirements. Worse than that — the men whose skill and wisdom are needed for the man- agement of great enterprises are deliberately worn out by m.echanical duties imposed upon them by the laws. I met, not long ago, the presi- dent of a large railroad-system, comprising more than thirty separate corporations, who told me that he was obliged to furnish once a month, under his personal oath, a statement of the business of each one of them. Being a conscientious and prudent man, he was not willing to swear to an account without personally examining it, and therefore he had to send for an auditor and go through a monthly statement with him more than once a day, the year round. I need hardly add that when I met this gentleman, he was "recovering his health." 6. The Interference of Government Agencies with Private Occupations. Under this head, I would mention only that aspect of the sub- ject which particularly concerns engineers and men of similar pro- fessions. Successive Directors of the U. S. Geological Survey have recognized the danger of setting up a disastrous competition with private experts. The members of that Survey are not permitted to take private work, or to put at the disposal of private employers the information they have gained as public officials. It is, therefore, only in Canada, Mexico, and other foreign countries that they occasionally become competitors of private engineers, who are trying to make a CONSERVATION BY LEGISLATION 33 living by the practice of their profession, and find themselves handi- capped in the struggle. But when the U. S. Forestry Bureau offered (I do not know whether the practice still continues) to furnish advice gratis to the private owners of woodlands, the offer tended to make it impossible for an educated and trained forester to earn a living by his profession, unless he could get an appointment in the U. S. Forestry service. The motive was good, no doubt: the desire to impress upon the people (and especially upon Congress) the value of scientific forestry. But the means were not justified by the end. This danger attends all governmental activity, outside of the pro- tection of person and property, the keeping of the peace and the en- forcement of contracts. Even things good or necessary for other reasons have this attendant disadvantage. Free public schools, for instance, we must have, if we are to have universal suffrage and other free institutions. Yet the better we make our free schools, the harder we make it for private schools to live; and now that in many places the position of a public-school teacher is open to the holder of a cer- tain certificate only, and advancement must come slowly, after long service in lower grades, we have well nigh brought it to pass that learning, or mastery of a given specialty, not commercially useful, is worthless. Who of us does not remember accomplished gentlemen of middle age, seeking in vain to earn their bread through the knowledge of ancient or modern languages, or of mathematics, which they have spent many years to acquire? This is a result of the competition of the free instruction given by the State. For other and overwhelming reasons, we must have that system; but we should not forget the high price we have paid for it by depreciating the practical value of that which we thus give away. Nor should we hastily pay a similar price for a less imperatively necessary public benefit. 6. The Half -Way Adoption of European Methods. Against this peril we should be specially on our guard. There are two distinct systems of governmental administration. Under what may be called the European system, governments have endowed and subsidized universities, schools, opera-houses, art-galleries, etc., and have organized industry, commerce, and even domestic life, under the supervision of officials, duly educated for the work, protected in their official posi- tions, promoted by seniority or merit, decorated for faithful service, pensioned when they are retired, and meanwhile secured in social rank by their membership in the civil service of the State. In consideration of these assured benefits, they serve honestly, intelligently and patiently, for very small salaries. We need not seek far for a parallel, even under our own institutions. The whole service of a European State is organized just like the regular Army and Navy of the United States. ^ 34 CONSERVATION BY LEGISLATION It works well with our Army and Navy. Indeed, nothing better could be imagined for military purposes. And the whole system is mag- nificent in its balanced details, wrought out in centuries of experience abroad. It is what we call "bureaucracy." The traditional American system is that of elected officials and "rotation in office"; the endowment and support of educational, scien- tific and philanthropic institutions by private benevolence, and the utmost freedom of personal enterprise and occupation. Personally, I think the American system is the best; partly because I believe, with Herbert Spencer, that a democratic government is the worst possible government to do those things which no government ought to do, and partly because, during the last hundred years, this nation, with its American system, has overtaken all foreign nations, in spite of their start of centuries, in precisely those respects in which their "paternal" system has sought to promote national prosperity and progress. More- over, when I was a student in Germany more than fifty years ago, and in every one of those fifty years since, I have known many accom- plished and aspiring engineers who had found government ownership, government supervision and government red-tape an intolerable bur- den and hindrance; and I am profoundly convinced that, in the long run, the utmost practicable liberty is better than the wisest practicable bureaucratic regulation. Moreover, I do not believe that our people would accept, or our institutions bear, the European system. My present purpose, however, is not to discuss the merits of either system, but to point out the danger of engrafting features of the one upon the other. If we are going to regulate everything by Govern- ment bureaus, then their employees must be appointed, removed and promoted without the least consideration of political influence, and pensioned upon retirement. Otherwise, we shall have the worst of all bureaucracies, namely, a temporary and fluctuating one. It is quite conceivable that, after a century of the American system, the time has come when we must face the necessity of adopting an- other. In that case, let us really face it, and not dodge it, or permit our choice to be foreclosed by "opportunism," which gradually leads us on until the power of choice is no longer ours. V. The Record of the Federal Government. We are familiar with the argument that what ought to be done for the welfare of our people, and has not been done by the several States, or could be better done by the Federal government, ought to be entrusted to that central authority. Concerning the constitutional argument on this point, I have nothing to say here. Let us assume that by amendment or "construction" of the Constitution, the thing could be done, if desired. The question is, would it be desirable? Of the many aspects of this question, I shall here present but one CONSERVATION BY LEGISLATION 35 — namely, the universal testimony of experience that the assignment of too many functions to a central government gives it more work than it can properly perform, and results, first, in the inadequate per- formance of its proper work, and secondly, in the neglect of its extra work, or the relegation of that duty to individuals or committees. The way in which Scotch, Irish, and Indian questions fare at the hands of the Imperial British Parliament has been often set forth as what seems to us Americans a strong business argument for the establish- ment of local legislatures in that Empire; and it is somewhat sur- prising to hear serious proposals that we should unnecessarily incur the same difficulties of administration. But we need not appeal to the experience of other nations. Our own Federal government has long been engaged in administering with full and unquestioned authority the affairs of the District of Columbia and sundry other reservations, tracts, and territories. What is the record upon which it can ask for any increase of the sphere of its authority? In answering this ques- tion, I am not indicting the Executive departments. The faults I shall point out are, perhaps, mostly those of Congress; but my aim is simply to show that, in a century of operations, the Federal government, as a whole, has not -discharged its obvious duties in such a way as .to warrant the conferment of additional authority upon it. 1. What has Congress done for the District of Columbia? How much time is given by that body to the affairs of that District? The District contains mines; has it any mining law? Only the other day we heard that, in an important civil case, involving the liberty of citizens, the U. S. Department of Justice was proposing to act under authority of a Maryland statute, nearly a hundred years old, which had been dug up as an authority, in the absence of any later legisla- tion by Congress. 2. The other day a friend, just returned from Alaska, informed me that he had found Indian tribes threatened with starvation because the U. S. authorities permitted the seines of the salmon-fisheries to lie continuously across the mouths of the streams and estuaries up which the fish were accustomed to run for spawning. On the Canadian shores the seines had to be removed for at least 24 hours in the week; and, of course, the absence of such a requirement on the American side was preventing the increase of the salmon, as well as starving the Indians. If Alaska were a State, and had control of the matter, such an evil would soon be remedied; but Washington was far away, and Congress was otherwise busy; and so both fish and natives were sacrified — a curious illustration of the conservation of natural resources.* * An inquiry, the result of which was received just after this paragraph had been printed, leads me to modify my statement on this point. It appears that there are U. S. regulations concerning the seine -fisheries; but I think it also appears that they are either inadequate, or inadequately enforced, or audaciously defied or evaded. The lamentable result is beyond doubt. 36 CONSERVATION BY LEGISLATION 3. But the crowning illustration of failure on the part of the w\ Federal government to deal competently with its clear and unques- VX tioned duty in connection with our natural resources is its treatment I \of the mineral resources of the public domain. This vast territory has belonged to the United States for more than sixty years (some of it, acquired by the Louisiana purchase, for a much longer period). Yet, at the present time, there is not a map in existence showing what mineral land is owned by the Government. Any one who "locates" a "lode" on the public domain thereby withdraws therefrom the tract covered by his location. His possessory title depends upon the per- formance of certain conditions ; but the initiation of it is not required to be made known to the Government at all. If you wish to buy from the United States a certain piece of mineral land which you have located, you are told : "We do not know whether we own it or not ; but you can have it surveyed, if you like, and then advertise for ninety days your desire to purchase it; and if nobody appears within that period to oppose your claim, we will conclude that we own the land, and will sell it to you!" Why have the public mineral lands never been surveyed? Why has notice of location never been required by the United States as a foundation of possessory title? There are other defects in the U. S. mineral laws, over which opinions differ, and for which it may be difficult to find satisfactory remedies; but these two points involve absolutely no political difference or difficulty. The first step towards the conservation of anything is an inventory of it; and until the government of the United States can show itself competent to per- form this simple duty as to the property explicitly put in its hands, I do not think it can be wisely intrusted with matters not so clearly within its sphere. In short, so far as the mineral resources of the country are con- cerned, I think the immediate duty of American mining engineers is to urge upon Congress the survey of the public mineral lands, and the enactment of a statute making the simple and reasonable require- ment that notices of location shall be filed in a U. S. Land Office within a certain period after the act of location. If there is not virtue and intelligence enough in Congress to take this obvious, necessary step, how can we trust that body, or its executive agents, to manage greater questions? And, as to the general problem of "conservation," / I I think it is the business of all engineers to pour cold water on hot heads, and prevent, so far as they may, the reckless operations of a sincere, but ignorant, enthusiasm. V'J THE WASTE OF OUK NATURAL RESOURCES BY FIRE. Charles Whiting Baker, M. Am. Soc. M. E. The topic assigned to me this evening is, in more senses than one, a "burning" subject. I know that statistics are apt to be dry, and statistics of fires naturally would be dry anyway. But I have to ask your attention to a few statistics of the waste due to fires. The United States Geological Survey has been engaged for some time on an investigation of the losses by fire in the United States. Through the courtesy of Kr. Herbert M. Wilson, of the Survey, I am able to give you some of the main results of this investigation which have not yet been published. The sum total of the losses by fire in the United States in the year 1907 was $215 000 000. About half of this $215 000 000 was loss upon the buildings themselves which were burned or injured by fire. The other half was upon the furniture, merchandise, etc., contained in the buildings. Besides this vast property loss, 1450 persons lost their lives in fires and 5 650 were injured. The fires which caused these losses of life and property occurred in 165 250 buildings, and the average damage to each building and its contents was $1 667. Notice that these are the direct losses only. No estimate has been made of the indirect cost of fires, the interruption to business, the expense of maintaining fire departments and of conducting fire insur- ance companies, which distribute the loss generally over the community. Also, these figures include only damages to buildings and their con- tents. There are, besides, the damages done by fires in mines and in forests to be taken into account to obtain the full record of destruction due to this element. Let us come back, howeyer, to these figures of total loss by fires in buildings in 1907. What do these figures mean? Do we really com- prehend their significance? We speak glibly of a million or a hundred million or two hundred million, but do these figures really create a vivid picture in our minds? I strongly suspect that we, as engineers, too often handle statistics and numbers and records without clearly comprehending how much — or how little — they mean. We handle them quite as the engineering student sometimes handles his problems in algebra or mechanics — X and Y and C" are just letters to him. He forgets that they symbolize actual concrete quantities. So we forget in dealing with large figures to visualize the bulk they represent. o8 WASTE BY FIEB Suppose we try to, picture to ourselves what these many millions of dollars' worth of valuable buildings in which fire annually rages would look like. Suppose it were possible to bring these buildings which were visited by fire in 1907 all together and to range them on both sides of a long city street. Let us place these buildings closely together, as they might be placed on an ordinary street in a fair-sized city. We will assume that the lots on which these buildings stand have an average frontage of 65 ft. How long a street do you suppose would be required to make room for all these buildings? Make a mental guess before I tell you, and you will then have some idea how accurate your conception of large numbers is. Perhaps you may guess that such a street would reach the length of Manhattan Island; or you may be bolder and guess that it would reach from New York all the way across New Jersey to Philadelphia. But those of you who are apt in that most useful branch of mathematics to the engineer — mental arithmetic — have perceived already, I doubt not, that the street will be far longer than this. I may say at once that this street, lined on both sides with the buildings visited by fire in 1907, would reach all the way from New York to Chicago. That is what the annual fire loss of the United States represents — a closely built-up street, a thousand miles long, with every structure in it ravaged by the destruc- tive element. Picture yourself driving along this terribly desolated street. At every thousand feet you pass the ruins of a building from which an injured person was rescued. Every three-quarters of a mile there is the blackened wreck of a house in which some one was burned to death. Imagine this street before the fire touched it, lined with houses, stores, factories, barns, schools, churches. Suppose the fire starts at one end of the street on the first day of January and is steadily driven forward by a high wind, just as actually happens in a conflagration. Building after building takes fire ; and while the fire fighters save some in a more or less injured condition, the fire steadily eats its way forward at the rate of nearly three miles a day, for a whole week, for a whole month, for all the twelve months of the year. And at the end of 1907 did the conflagration end? No; it began on a new street, a thousand miles long, which was likewise destroyed when 1908 was ended. And this same destruction is going on to-day. But you say, do not the figures you have quoted represent an unusually bad year? And are not the improvements in construction — the better building laws, the better fir6 protection — showing in diminished fire losses? Unfortunately I have to answer No to both questions. The statistics of fire losses gathered for many years by the National Board of Fire Underwriters show that the annual fire loss has been steadily increasing. In the ten years ending with 1907, the annual fire loss averaged $203 000 000. In the ten years ending with WASTE BY FIRE 39 1897, it was $132 000 000. In the ten years ending with 1887, it was $92 000 000. Thus our fire loss has doubled in 20 years. Of course, the increase in population, in wealth, in number of buildings, means that more property and lives are at risk from fires, and accounts for the increase in total fire losses that the past 30 years has shown. But that increase has not been noticeably checked by anything which we have done to reduce the fire risk. But again you say, is not this fire loss a necessary evil? Must not a certain risk of fire be incurred in any building ? Is there anything to show that the total fire loss, the risk to property and to life can be reduced? These are fair questions, and their answer may lead us to take what I may call a common-sense view of the subject. A certain amount of loss by fire must be expected. Safety and danger are relative terms, and there is no such thing as absolute safety. But we have only to look at the records of fires in European countries to learn that our fire losses are very, very far beyond those of any other country of advanced civilization. The fire loss in the United States in 1907 represented an annual per capita tax of $2.50 on every man, woman and child in the population. That means a tax of $15 a year on the head of every family of six persons. In the principal European countries the fire loss per capita per annum is as follows: Italy, 12 cents; France, 30 cents; Austria, 29 cents; Germany, 49 cents. Allow- ing for the fact that European populations are far more dense than our own, it is yet evident that their losses are only a small fraction of those in the United States. It is only in Russia and Norway, where wooden buildings form a considerable proportion of the whole, that the fire loss per capita approaches even half of our own per capita rate. I have referred to a common-sense way of treating this question of fire risk. It seems to me that the common-sense way is to reduce fire risk by better construction whenever and wherever it will pay to do so. The engineer's business is to make a dollar earn the most interest. If a structure will represent a smaller annual cost for its whole life, insurance and fire risk taken into account, when built of wood than when built of iron or brick or stone or concrete, then and there wood is the material to use. Deplore as we may the loss of the forests, the engineer, like every one else, is hemmed in by economic laws andj, , market prices and cannot stray far from the bounds that they set or he/ ■ \j 'J will find his occupation gone. But — and this is a big but — the trouble is that the public — and the engineers with it — is apt to run on in a rut. We go on building in the old-fashioned way, because at one time it was the cheapest and we are not wise enough to realize the economy of newer methods. Nothing but high and higher prices for lumber will bring us to our senses and induce us to wake up and bring ourselves and our practice up to date. I said, you remember, use better construction whenever and wher- 40 WASTE BY FIRE WWl ever it will pay to do so. I use that word pay in a very broad sense. It may pay the builder or the owner best to put up a cheap building, which will be a danger to tenants and a menace to all adjacent build- ings. A hundred or a thousand such buildings, huddled in a city, make the possibility of a conflagration. Thus comes about the necessity of laws to regulate building. We have erred in the past and still err all over this broad land, because we have laid overmuch emphasis on the right of each individual to do as he pleased with his own. And we have been slow to realize that this liberty often degenerates into license to do as he pleased with the rights and the property of his neighbors. I do not overstate the case when I say that our American cities and villages are made up almost wholly of fire-trap buildings. We have lagged far behind in our adoption of better and safer methods of build- ing construction. We must for at least a generation to come pay the penalty of heavy charges for fire protection, heavy insurance rates, heavy fire losses. And we must continue to bear this heavy tax until we rebuild our cities with fire-resisting structures. Fortunately the engineer has provided the means and the materials by which better and more economical construction can be substituted. It was the circular saw and the railway that created cheap timber throughout the 19th century and housed the people of the United States in cheaply built and easily burned wooden buildings. It is the rotary kiln for burning Portland cement, the rock drill, the brick press, and a thousand other modern inventions that are to create the incom- bustible buildings which the 20th century is to construct. Let us not forget, either, that incombustible buildings are only one part of the art of fire-protection engineering. Most of the materials of commerce are combustible. Many are highly inflammable. We must protect the contents of warehouses and factories, even though the structure be safe. I know of no better proof of the possibilities in the field of fire prevention than what has been actually accomplished by the Factory Mutual Insurance Companies of New England. These companies, insuring chiefly mills which handle cotton, one of the most inflammable of materials, have reduced their rate of loss to about 5 cents per annum per $100 insured, a rate of loss little more than a tenth, probably, of the average fire loss on all classes of buildings in the United States. I cannot refrain from saying that among the pioneers who have done most in accomplishing this feat in conservation — in the prevention of waste — is the first speaker of this evening, Mr. .John R. Freeman. The automatic sprinkler, the automatic fire alarm and many other devices, with the organization and discipline of fire-fighting forces, and inspection for fire prevention, have transformed one of the most dangerous classes of fire risks to one of the safest. WASTE BY FIRE 41 I remember my old professor of rhetoric telling me that a model sermon should be like a kiss — two heads and an application. My sermon on this burning question must draw to a close, but I must say just a word under my second head, which is forest fires. I will not bore you with many statistics of forest-fire losses. Surely, surely the memory of the forest fires which raged last September and October and of the vast losses of property and the terrible losses of life which then occurred is too near and too vivid to need more than a passing allusion. The fires which raged in the Adirondack region last fall burned over an area of 347 000 acres or 542 sq. miles. About 38% of this area bore merchantable timber. This damage was done within the limits of one single state. I leave you to form your own estimate of the value destroyed by these fires and by the multitude of other fires which raged through New England, in Pennsylvania, in the pine forests of Wisconsin and Michigan and Minnesota and in the Southern States. And the worst result of the forest fire — even worse than the destruc- tion of valuable timber and young growing trees which should furnish the lumber that will be so sorely needed a quarter century hence — is the destruction of the soil itself. There are many hundreds of square miles in the Adirondack region where forest fires have burned away the wood soil and humus and have destroyed the possibility of repro- ducing the forest growth — at least for long years to come. Is it a light thing that these vast areas, which might under proper administration go on producing year after year a steady crop of timber, should be reduced to barren desert? What I most want to make clear to you is that unless and until you create in every forest State of the Union effective laws and effective organization to prevent forest fires — unless and until you do that thing — all our talk of conserving the forests is vain. We cannot | a get away from economic laws. We cannot expect a man to preserve >- ', valuable woodlands uncut when at any time a forest fire may wipe out the property entirely. And the higher the price of lumber goes, the greater the inducement to cut off the trees. Thus the more our forests dwindle and the nearer the inevitable timber famine approaches, the more certain we make it that all the forests shall disappear. If a man could hold his timber lands like other property for a higher price without risk of total loss, many would prefer to do this, and many would be found to undertake timber culture; but, so long as timber properties are subject to grave risk of total loss, they cannot be attractive to capital. \ I may be criticised for saying very little so far about conservation. ' But surely little need be said to prove that the fire loss is a waste and a vast drain upon our natural resources. Every one appreciates it, of 42 WASTE BY FIRE course, where forest fires are concerned; but it is just as much of a drain on the forests to burn up the boards and the timber in a house which must be rebuilt as to burn up the trees before they are cut down and sawed. And not only timber but iron, tin, lead, zinc — all the materials used in building construction — and a vast amount of mer- chandise contained in buildings are devoured annually by the flames. Surely, then, the prevention of this waste — the work of the structural engineer and the fire-protection engineer — is a task whose accomplish- ment means much for the public benefit, means much for the conserva- tion of the world's resources. ELECTKICITY AND THE CONSEEVATION OF ENERGY. Lewis B. Stillwell, M. Am. Inst. E. E. In any problem accurate and, so far as practicable, concise state- ment is essential to proper consideration and correct solution. The economic problems which present themselves when the complex and far-reaching subject. Conservation of Natural Resources, is considered, can be approached best by first stating and defining them with refer- ence solely to physical and economic facts and relations without refer- ence to political boundaries or limitations. To approach the subject by considering, first, real or supposed difficulties imposed by the re- spective rights and duties of states and of the nation is to discuss method of treatment before diagnosis. We should consider the prob- lem first as if there were no such thing as states within the Union, assuming, for the time being, within the Federal boundaries the existence of one central and absolute authority. The question what upon this assumption is economically desirable, is that which the En- gineering Profession should first agree upon and, if possible, state in a manner which will be understood by the general public. Conservation as applied to our natural energy resources means utilization without unnecessary waste. In a broader sense it means also development along lines which will not only utilize but increase those resources; for example, as regards water powers it has relation to the maintenance and renewal of forests affecting variations in stream flow, and the construction of storage reservoirs which, properly used, are capable of adding greatly to that part of the run-off which can be used for industrial purposes and navigation. Much has been uttered recently with reference to these relations which cannot be expected to hold good in the light of that clearer knowledge which will result from further study and experience — much that is erroneous and misleading even when examined critically in the light of facts now ascertained and determined. General state- ments from sources commanding the attention and arousing the inter- est of the public are necessary first steps in turning a nation from reckless waste and almost unrestricted appropriation of natural re- sources by individuals to a policy of wise conservation, having due regard to the common interest now and in the future. Those first steps have been taken, on the whole, in an admirable manner. Public attention has been arrested. Public interest has been aroused. Public and legislative opinions are forming. Obviously, it is of the utmost importance that our engineering societies should take an immediate 44 ELECTRICITY AND THE CONSERVATION OF ENERGY and active part in working out the complex problems of conservation and, if possible, in directing the formation of public opinion along lines that will result in the enactment of just and wise laws. The economic utilization of our natural resources is the funda- mental problem of all engineering. If the President of the United States were to summon a conference of Governors at the White House for the purpose of considering and promoting reforms in current medical practice, the medical profession undoubtedly would be greatly interested and would manifest its interest by assuming proper and unchallenged prominence in discussing the questions raised. If such a conference were to assemble for the avowed purpose of initiating reforms in the machinery and methods for the administration of justice, it is not to be doubted but that the lawyers would manifest their vital interest not only by exposition and discussion but also by actual leadership. The conference of governors in May, 1908, called by President Roosevelt to consider and advise regarding conservation of the natural resources of the United States, raised questions in respect of which the engineer occupies a position closely analogous to that which the medical doctor holds in respect of medical practice and the lawyer in respect of legal procedure and administration. The analogy is not perfect nor does responsibility for final decision rest exclusively upon the engineer, but it is peculiarly the patriotic duty of the Engineering Profession to enlighten the public by unbiased consideration and accurate exposition of essential pertinent facts, physical and economic. — I propose in this paper: 1. To illustrate the function of electricity in the conservation of natural resources. 2. To summarize statistically the present power requirements of the United States and present certain data (necessarily far from complete) relative to water power available. 3. To point out certain economic bearings of the plan which proposes the imposition of a tax on water powers and the use of the proceeds for improvement and construction of inland waterways. The Function op Electricity in Conservation. The part which electricity is destined to play in the conservation of our energy resources is demonstrated clearly by what it already has accomplished. Three typical illustrations will suffice: 1. The saving of coal by the utilization of water power, as illustrated by the plants of the Niagara Ealls Power Company. 2. The saving of coal by the sub- stitution of large and highly efficient steam plants for smaller and less efficient plants, as in the case of the Newcastle-upon-Tyne Electric Supply Company. 3. The saving of coal used for transportation pur- poses by the substitution of large and highly efficient engine units for comparatively small and inefficient locomotive units, as accomplished. ELECTRICITY AND THE CONSERVATION OF ENERGY 45 for example, by the Interborough Eapid Transit Company of New York. In each case the economy is due primarily to the fact that we can now use for transmitting and distributing power the electricity pro- duced in dynamos, distributed by conductors, and utilized by motors, all of remarkably high efficiency. The Niagara Falls Power Company. — During the year 1908, the plants of the Niagara Falls Power Company delivered an output of 560,000,000 kw-hr. Had this output been generated by large modern central stations using steam power, their consumption of coal would have approximated 2,000 tons per day. Were the users of Niagara power dependent to-day upon their own individual steam plants, they would use in the aggregate not less than 3,000 tons of coal per day; in other words, more than 1,000,000 tons per annum. If this power were replacing steam, as used under average conditions in our manu- facturing cities, instead of being used for the most part in supplying power to comparatively a small number of customers using large blocks of power, it would replace and save nearly 2,000,000 tons of coal per annum. Important as is the saving of coal from the standpoint of con- servation of our natural resources, perhaps the most striking feature of the Niagara power enterprise is the demonstration which it affords of the great industrial value of cheap power; the greater part of the output of the plants being utilized to-day by electrochemical indus- tries of great value to the community, all of which have been stimu- lated and some of which owe their very existence to their ability to obtain power at very low cost. The North-East Coast Power System. — The North-East Coast Power System, supplying electric power to the great industrial dis- trict in and about Newcastle-upon-Tyne, effects a very important economy in coal consumption. In a paper presented at the Middles- brough meeting of the British Iron and Steel Institute, in 1908, Mr. Charles H. Merz, the engineer under whose able direction this large enterprise has been carried out, shows that the economies resulting from centralization of power development and electric distribution have led to the construction of plants now in operation aggregating 102,000 h. p. installed; that additional plant aggregating 34,600 h. p. is under construction; that during the last 4 years the demand has increased at a rate averaging 20,000 h.p. per annum; that to-day every shipyard on the north bank of the Tyne is purchasing practically all of its power supply in the form of electricity; that the system is now: "Kesponsible for the supply of current to 80 miles (single track) of electrified railway, four tramway systems, the lighting in towns having populations aggregating over 700,000, motive power to the extent of 85,000 horse-power and electrochemical works over 12,000 horse-power.". 46 ELECTRICITY AND THE CONSERVATION OP ENERGY Not only has Mr. Merz established highly successful steam-driven power plants in a district where the cost of coal ranges from 7s. to 9s. per ton, but he has demonstrated that important economy of coal consumption results from the supply of electric power to the collieries for their mining operations. Referring to this very interesting feature of the development, Mr. Merz says; "The output of coal from Northumberland and Durham in 1906 was over 62,000,000 tons, and, according to the Report of the Royal Com- mission on Coal Supplies, between 6 and 8 per cent, of the total coal brought to bank is used by the collieries for the purpose of power generation. From the make of coke * * * it appears that about one-fifth of the coal mined on the north-east coast is converted into coke. Making a liberal allowance, therefore, for the power at present used from the surplus heat resulting from the coking process, the collieries of Northumberland and Durham must burn for their own power requirements some 2,500,000 tons of coal per annum. As the almost invariable rule is to work non-condensing, as the steam piping is usually long, and as a large portion of the load is intermittent, it is certain, and is proved by experience in this district, that the same power can be provided electrically in a large central power station by the consumption of less than a quarter of this coal. Apart, therefore, from the efficient utilization of waste heat, * * * apart from the saving of coal in ship-building and engineering works, and apart from the saving resulting from the electrification of railways, the application of electricity to coal-mines in this district, when as complete as that to the Tyne shipyards, will render available for outside sale over If millions of tons coal, equivalent to, say, over half a million sterling per annum." The Power Plants of the Interborough Rapid Transit Company of New YorTc. — The output of the power houses of the Interborough Rapid Transit Company, New York, for the year 1908, was 409,000,000 kw-hr. The consumption of coal was 494,000 tons. In a paper pre- sented at the 214th meeting of the American Institute of Electrical Engineers, by the writer and Mr. H. St. Clair Putnam,* comparison was made from the company's operating records of the fuel consump- tion upon the Manhattan elevated lines during the year ending June 30, 1901, when steam locomotives were employed, and during the year ending June 30, 1904, when electricity was used. I quote from this paper : "During the period first mentioned, one pound of coal produced 2.23 ton-miles, if the weight of the locomotive be included, and 1.5 ton- miles, if the weight of the cars only be considered. "During the latter period (electric traction), one pound of coal burned at the power house produced 3.85 ton-miles, excluding weight of locomotives; therefore, the ratio of ton-mileage per pound of coal * Transactions, A. I. E. E., 1907, Vol. XXVI, p. 81. ELECTRICITY AND THE CONSERVATION OF ENERGY 47 in favor of electric operation was 2.57 to 1. Including weight of loco- motive it was 1.72 to 1. "The average speed under electric operation was approximately 2 miles an hour greater than that attained by steam, and if correction be made for this difference the ratio of ton-mileage per pound of coal, excluding weight of locomotives is approximately 3 to 1, and including locomotives, 2 to 1 in favor of electric traction." If, therefore, we can conceive the possibility of operating to-day, by locomotives, the entire service of the elevated and subway lines of the Interborough Company, it appears that the saving in coal con- sumption effected amounts to not less than 988,000 tons of coal per annum. In each of the three typical cases cited, it will be noted that elec- tricity results in a radical economy of coal. That it also results in a material saving of household and other property which, in industrial communities using large numbers of small steam plants, suff(er rapid deterioration by the effects of smoke and dust; that it tends strongly to improve the appearance of our cities and conditions which affect comfort and health, are facts not all of which are strictly pertinent to a consideration of the subject before us, but may, nevertheless, be mentioned in this connection. Where steam is used to generate power in large plants from which electricity conveys it to users, economy results not only from the employment of comparatively large power-generating units, but also from the introduction of plant economies and a degree of skill not attainable in smaller plants. Industrial Use of Power. From the latest available census returns, the following tabulation of aggregate capacity of prime movers used in the United States at the dates and in the respective industries mentioned, is compiled: Installed horse power. Manufactures, census 1905 12,765,594 Mines and quarries, census 1902 2,753,555 Street railways, census 1902 1,359,289 ^ Electric light and power stations, census 1902 . . 1,845,048 ^' Custom flour, grist and saw mills, census 1900 (omitted from census 1905) 883,685 Telephones, telegraph and fire-alarm systems, census 1902 3,148 The United States census reports since 1870 afford data from which interesting * conclusions in regard to the respective rates of in- crease of power used for various industrial purposes, the relative proportions of steam and water power now in service and the enormous growth of electric motor applications may be investigated. Such a 48 ELECTEICITY AND THE CONSERVATION OF ENERGY Y^ study has been made by Mr. H. St. Clair Putnam, of New York, and \ the results set forth in an interesting paper on "Conservation of I Power Resources/'* presented by him at the conference on the Con- servation of Natural Resources, held at the White House, May 13-15, £^908. Mr. Putnam employed the method of constructing curves based upon census statistics beginning with the year 1870, and projecting the resulting respective curves from the dates of the latest census figures to the year 1910. Making due allowance for the check to our industrial progress, which began in 1907, it is safe to say that at the present time the aggregate horse power of prime movers installed for industrial use in the United States, exclusive of steam railways, ap- proximates 25,000,000. In round numbers, 50,000 steam locomotives are owned by our rail- way systems. Based upon maximum drawbar pull, these locomotives would be capable of developing about 30,000,000 h.p., but the average power actually developed on a 24-hr. basis, when averaged over the entire year, approximates only about 2,000,000 h.p. Were all the railways of the United States operated by electricity generated in large and properly located power plants, the aggregate installed capacity of these plants would approximate 4,000,000 h.p. Qf the grand total of 25,000,000 h.p. installed for industrial pur- poses, exclusive of steam railway operation, water motors represent, in round numbers, 6,000,000 h.p., and gas and oil engines about a00,000.h.p. iV I quote from Mr. Putnam's paper: * "Prior to 1870 the use of water power in manufactures exceeded that Lof steam power. W^ater power expressed in percentage of the total power employed has since steadily declined, falling from 48.3% in 1870 to 11.2% in 1905. During the corresponding period, steam power in- creased from 51.8% in 1870, to 78.2% in 1900. The census of 1900 showed a marked falling off in the rate of increase in the percentage of steam power used as compared with the rate prior to 1890, and this was accentuated in the census of 1905, when the percentage of steam ^power fell to 73.6% of the total. This check to the ascendency of directly applied steam power was due to the introduction of electric power. In 1890 electric power was negligible. In 1900 it constituted 4.8% of the total. In 1905 this had increased to 11.8% — a marvelously rapid growth when the aggregate increase of over 1,000,000 h.p. in five years is considered. If the present rate of increase prevails until 1910, electric power will have reached 18 per cent, of the total, and steam ^^ower will have dropped to 68%." The facts to' which I have called attention point unquestionably to further and rapid progress of the work of substituting electric motors for small steam engines. While this development has made a highly significant beginning in the field of transportation, in the replacement * Proceedings, A. I. E. E., Vol. XXVII, p. 1397. ELECTRICITY AND THE CONSERVATION OF ENERGY 49 of steam locomotives for elevated and subway service and for terminal operation, it has already covered a substantial portion of the entire field of stationary operation. Its economies and their advantages are fast becoming matters of common knowledge. The cost of electric apparatus in general has decreased materially in the last decade, and the day appears not far distant when the isolated steam engine plant as used for general industrial purposes will be practically banished from our cities. Our ability to utilize in the near future a large proportion of our water powers depends primarily upon the distance across which power can be electrically transmitted at practicable costs. This in turn depends upon the limits of potential against which transmission lines can be insulated in a manner which secures reasonable continuity of service. No precise limit of practicable distance can be fixed nor is it~] necessary here to enter into a detailed discussion of the subject. It is sufficient to point out that power to-day is being transmitted from Niagara Falls to Syracuse, a distance of 160 miles. In California, it j has been transmitted successfully a distance exceeding 200 miles. J While 200-mile transmission does not bring every water power of the country within reach of an adequate market, it does obviously suffice as regards a large proportion of our hydraulic resources not as yet utilized* Available Water Power. From a purely physical standpoint, an estimate of horse power available in the case of a given stream requires accurate topographical survey and careful measurement of flow extending over a considerable period of years. Much work of very great value has been accomplished in these directions by the United States Geological Survey, but much still remains to be done. Systematic prosecution of this work is essen- tial to the ultimate solution of our problems of power conservation and the influence of the Engineering Profession should be strongly exerted to insure the effective extension and continuance of these sur- veys and measurements. The majority of estimates of "water power available in the United States," which have been made, do not and cannot pretend to be exact. Obviously, there is a vast difference between the aggregate horse power which may. be considered available, if the problem be looked at from a purely physical standpoint without reference to cost of develop- ment, and the amount which is available if cost of development and transmission to an adequate market is considered. From the economic standpoint, determination of the aggregate horse power which a stream is capable of developing involves a step-by-step examination of its profile from its source to its mouth, the approximate location of sites where the gradient and other topographical features 50 ELECTRICITY AND THE CONSEEVATION OP ENERGY indicate the practicability of development within the limit of prac- ticable cost as fixed by cost of competing steam power and the sum- mation of the powers thus located. Following this general method, Mr. M. O. Leighton, Chief Hydrographer, United States Geological Survey, estimates the available water power of the upper Mississippi River and tributaries at 2,000,000 h.p. and that of the southern Ap- palachian region at approximately 3,000,000 h.p. The aggregate avail- able water power in the State of Washington has been estimated at 3,000,000 h.p. and that of northern California at 5,000,000 h.p., but these figures are merely approximations and cannot be regarded as authoritative. The report of the Inland Waterways Commission, acting as the Section of Waters of the "National Conservation Commission," before the recent Joint Conservation Conference in Washington, states: "The theoretical power of the streams is over 230,000,000 horse- power; the amount now in use is 5,250,000 horse-power. The amount available at a cost comparable with that of steam installation is esti- mated at 37,000,000 horse-power, and the amount available at reason- able cost at 75,000,000 to 150,000,000 horse-power." The assumptions and facts upon which these estimates are based are not set forth in the report referred to with that precision which is essential to correct judgment of their value. The amount named as "available at a cost comparable with that of steam installation," namely 37,000,000 h.p., exceeds the aggregate mechanical power now in use within the borders of the United States and suggests the enor- mous saving in coal which would result from anything like a general development and utilization of our water powers. But whatever may be the aggregate amount which ultimately can be utilized, certain guiding facts are obvious and cannot be contro- verted. Among these are: 1. Under average conditions every hydrau- lic horse power utilized for industrial purposes in 10-hr. service saves at least 7.5 net tons of coal per annum. 2. Present knowledge does not permit us to obtain from coal burned for power purposes, even under conditions of best commercial practice, more than 10% of the energy which it contains; under average conditions less than 5% is utilized. 3. Electricity enables us to substitute a few and compara- tively efficient steam plants for large numbers of small and relatively wasteful installations; thus effecting important economies not only in fuel consumption, but also in other directions. It also enables us to transmit and utilize in available markets a very large proportion of the aggregate water power of our streams. In view of these facts, it will be admitted that from the stand- point of conservation of our power resources, the attitude of the Federal and State governments should be such as will hasten and not retard the development of our water powers. Any policy which ELECTRICITY AND THE CONSERVATION OF ENERGY 51 operates to retard this utilization is a damage to the community, not only because it tends to increase the average cost of power and, there- fore, of transportation and the manifold products of our manu- facturing industries, but also because it tends to prolong and even increase the, at present, necessarily wasteful utilization of coal supplies which can never be replaced. Such a policy, therefore, is on its face in direct contravention of the true principles of conservation. __ Water powers not hitherto appropriated under existing laws belong to the state and unquestionably should be utilized in a manner which will secure the utmost practicable advantage to the community. There is every reason why they should not be appropriated in perpetuity either by individuals or corporations. In permitting their appropria- tion and use for a limited period, the state undoubtedly should obtain the best terms possible, but the fact that prompt utilization means not only a saving of coal resources but a reduction in cost of manu- facture and transportation is a consideration of the utmost weight. As compared with the direct revenue which can be expected to result from levying a direct tax upon water powers, this consideration, from a broad economic standpoint, is in all probability controlling. Doubt- less the state can tax water powers and can devote the proceeds of such tax to any special purpose which it may elect, for example, the con- struction of inland waterways, as has been proposed, but correct determination of the wisdom or folly of such an arrangement requires careful consideration and at least approximate knowledge of the quantitative values of the economic results to be expected. In a short speech before the Conference of Governors at the White House in May, 1908, referring to water powers. President Eoosevelt said: "My position has been simply that where a privilege, which may be of untold value in the future to the private individuals granted it, is asked from the Federal Government, that the Federal Government shall put on the grant a condition that it shall not be a grant in perpetuity. Make the term long enough so that the corporation shall have an ample material reward. The corporation deserves it. Give an ample reward to the captain of industry but not an indeterminate reward. Put in a provision that will enable our children at the end of a certain specified period to say what in their judgment should be doiie with that great natural value which is of use to the grantee only because the people as a whole allow him to use it. It is eminently right that he should be allowed to make ample profit from his development of it but make him pay something for the privilege, and make the grant for a fixed period, so that when the conditions change, as in all probability they will change, our children — the Nation of the future — shall have the right to determine the conditions under which that privilege shall then be enjoyed." With the ideas thus vigorously expressed, every good American citizen must be in sympathy. To the admirable exposition of principles 62 ELECTRICITY AND THE CONSERVATION OP ENERGY included in the preliminary report of the Inland Waterways Com- mission, dated February 26, 1908, few engineers will take exception. But the attitude of some of the speakers at the recent Conservation Conference in Washington, upon the occasion of the second gathering of the Governors of the States, clearly evidenced a disposition to beg one of the fundamental questions which arises at the very threshold of consideration of the utilization of our streams ; namely, the question of the real economic value of inland waterways. The minds of some who are taking an active part in the discussion of this great economic question apparently start with two assumptions: 1. That the economic value of a vast system of inland waterways is admittedly so great as to justify practically any expenditure in its development. 2. That the water powers upon our streams are inexhaustible mines of wealth capable of yielding, under a general system of taxation, large revenues. From these premises the conclusion that water powers should be taxed to pay for waterways is easily deduced. To the engineer it is evident at once that before any conclusion involving expenditure of large amounts either of public money or private capital is agreed to, both premises upon which that conclusion is based should be critically examined. I do not propose in this paper to attempt anything purporting to, be an exhaustive discussion of this complex subject. Personally I am frank to admit I have found it impossible from my present knowledge to form definite and final opinions in respect of some of its phases. If our national engineering societies, during the coming year, will procure from their members best qualified by special knowledge to supply pertinent facts and suggestions, carefully considered papers discussing the comparative economics of transportation by rail and by inland waterways, much light will be thrown upon this very important and far-reaching question. At present, data apparently essential to well-grounded judgment have not been collected and compared in a manner to justify formation of definite and final opinions which can be expressed in precise terms ; opinions which may be expected to stand the test of time. In calling attention to certain considerations which apparently tend to controvert the present popular impression that a radical improvement and extension of our inland waterways is the natural and proper solution of the great problem of freight transportation, I trust it will be understood that I am not approaching the subject from the standpoint of one whose interests are identified with railways. Such is not the case. The electrical engineer has everything to gain and probably nothing to lose from a policy which during the next 10 years may result in the appropriation of from $50,000,000 to $100,000,000 per annum for the improvement of our waterways and development of our water powers. An engineer's first duty in a case ELECTRICITY AND THE CONSERVATION OF ENERGY 63 of this kind is to bring any special knowledge which he possesses to bear upon the economic problem presented, to form and to state his opinions absolutely without bias. In our offices and in the fiel(r,"we ^i may be retained properly to represent this or that special interest, ; but on the floors of our engineering societies our proper attitude is ' that of the man of science interested solely in the facts, their causes,^ relations, and consequences. In considering the proposition to impose a tax upon water powers and devote the proceeds of this tax to the construction of a system of inland waterways, it is clear that the first effect of such a tax is to retard the development of water powers unless some compensating advantage is offered. It is also evident that such a tax operates indirectly to stimu- late the consumption of coal, and that if it be decided that we can afford to tax manufacturers indirectly in order to improve transporta- tion facilities it would be wiser, from the standpoint of conservation of our power resources, to impose a tax upon coal used for power purposes. A tax of $3.00 per horse power ($4.00 per kilowatt) per annum is equivalent to a tax of 40c. a ton (2 000 lb.) on coal used for power purposes in manufacturing, if we assume that 5 lb. of coal per horse power-hour are used. A proposal to impose any such tax on coal used for power purposes and use the proceeds for the construction of inland waterways probably would command little influential sup- port and yet a similar proposal, as applied to water powers, has received weighty endorsement and apparently is highly approved by those who are especially interested in the development and extension of inland waterways. In the report of "The Inland Waterways Commission, acting as the Section of "Waters of the National Conservation Committee before the last Joint Conservation Conference," I find the following referring to the uses of water power in our streams: "The paramount use should be that of water supply; next should follow navigation in humid regions and irrigation in arid regions. The development of power on the navigable and source streams should be kept subordinate to the primary and secondary uses of the waters; though other things equal, the development of power should be encour- aged, not only to reduce the drain on other resources, but because properly designed reservoirs and power plants retard the run-off and so aid in the control of the streams for navigation and other uses." It would be interesting to know how the conclusion has been reached that in humid regions the development of power on our streams is less important than the improvement of navigation. To one familiar, for example, with power developments in the cotton mill district of the Carolinas and with the character of the streams there utilized so extensively and with such vast advantage to the com- munity for power purposes, the idea that any conceivable use of these 'J 54 ELECTRICITY AND THE CONSERVATION OF ENERGY streams for purposes of navigation can be comparable to their value as producers of power is to say the least highly improbable. Obviously before any such general policy as that recommended is adopted, we should have assurance that the imposition of such a tax will not cost the community more than the resulting improvement of transportation facilities is worth. Cheap power is a factor of great importance, both in manufacturing and transportation. According to the census of manufactures taken in 1905, the gross output of our factories and mills had a value of $16,866,706,985. The product repre- sented $1,152.00 per horse power installed. The wages paid amounted to $248.00 per horse power installed. In the same year, the aggregate gross receipts of our railways were $2,325,765,167, or about 14 per cent, of the value of manufactured products. The object sought in constructing inland waterways is reduction in cost of transportation. The proposal to impose a tax which will operate to increase costs, in a business amounting to nearly $17,000,000,000 per annum, in order to attain an undefined advantage in reduction of cost in a business of less than one-seventh that amount, calls for something further in the way of analysis than has yet come under miy observation in this connection. The fact that manufacturing costs in America are in general much higher than in Europe, while our cost of transportation per ton-mile is now materially lower than can be found elsewhere, emphasizes the impression which results from a moment's consideration of the respective gross volumes of business in these allied fields of industry. It would be impossible to suggest a more fruitful subject for un- prejudiced analysis and illuminating exposition by competent members of our national engineering societies, in the immediate future, than the comparative economic advantages of railways and inland water- ways. Facts in this field are urgently needed and should be supplied before public sentiment, unenlightened by unbiased competent advice, and influenced, perhaps, by prejudice and the clamor of local interests, shall crystallize in legislative enactment or executive rulings. Within the last two years, my firm, in considering problems presented by the substitution of electricity for steam in railway operation, has carefully studied the cost of operation of steam railways in the United States, using as the basis of this investigation not only the valuable reports of the Interstate Commerce Commission, but also detailed operating cost-sheets confidentially furnished for the purpose by a number of the most important railways in the country. It also happens that within the same period we have had occasion to determine with great care the actual cost of operation of one important canal system, and in this con- nection have secured considerable information bearing upon the general question of the economics of canal transportation. The conclusions ••«••* * s • « > 1 > * * • ELECTRICITY AND THE CONSERVATION OF ENERGY 55 which we have reached as a result of these comparative investigations do not support broadly and without material qualifications the popular impression that transportation of freight by inland waterways, in general, is less expensive than transportation by railways. In engineering matters, general statements almost invariably are subject to exceptions and I am not prepared to assert broadly that the construction of canals for transportation purposes is a mistake. I do assert, however, that in the majority of specific instances that have come under my observation the facts are far from justifying, from an economic standpoint, a propaganda aiming at the development of a general system of inland waterways beyond what may be attained by reasonable improvement of the channels of navigable streams with such comparatively short inter-connecting canals as may beyond rea- sonable doubt be justified by the results attained. As regards the proposed "concurrent development of the streams and their sources for every useful purpose to which they may be put," as it is stated in the "declaration of principles" of the recent North American Conservation Conference, all engineers will agree that each stream should be studied with reference to its possibilities "for domestic and municipal supply, irrigation, navigation, and power, as interrelated public uses." But the development of a plan economically sound calls for unbiased consideration and fairly accurate knowledge of the economic value to the community of the resulting improvement of the stream regarded as a waterway for transportation. Obviously if we begin by assuming that because freight is carried across the Atlantic or through the Great Lakes at less cost per ton-mile than it is carried by our railways, an increase in the depth of channel or improved regularity of flow of any given inland stream will secure corresponding results, we shall be misled and expenditures based upon any such assumption will be wholly or largely wasted. Each case should be studied and competently studied on its own merits. To tax water powers for the purpose of providing free waterways, from a broad economic standpoint, is a policy which, before adoption, should be compared carefully with the plan of imposing tolls upon all users of inland waterways and using the proceeds to develop water powers and secure cheaper power for our manufacturing industries. The declaration of principles agreed upon by the recent North American Conservation Conference makes the following statement: "We recognize the waters as a primary resource, and we regard their use for domestic and municipal supply, irrigation, navigation, and power, as interrelated public uses, and properly subject to public con- trol. We, therefore, favor the complete and concurrent development of the streams and their sources for every useful purpose to which they may be put." 56 ELECTRICITY AND THE CONSERVATION OF ENERGY In the preliminary report of the Inland Waterways Commission, dated February 26, 1908, I find the following: "While navigation of the inland waterways declined with the in- crease in rail transportation during the later decades of the past century, it has become clear that the time is at hand for restoring and developing such inland navigation and water transportation as upon expert examination may appear to confer a benefit commensurate with the cost, to be utilized both independently and as a necessary adjunct to rail transportation." [The italics are mine.] The fundamental facts here set forth will receive the unanimous and enthusiastic endorsement of the entire Engineering Profession. In determining, however, how the a^irkbte'and'^a^ly important objects in view are to be attained, every engineer should use his best en- deavors to prevent fundamental and far-reaching mistakes which easily may result from action based upon insufficient or inaccurate knowledge. ^ ^^ UNIVERSITY OF CALIFORNIA LIBRARY BERKELEY Return to desk from which borrowed.
