JOHN, NEW BRUNSWICK. CHARLOTTETOWN, P. E. ISLAND; COOMBS & WORTH, STEAM PRINTERS, i8 QUEEN STREET. z88z. •' V REPORT » To His Worsliip the 2fai/or, and (he Citi/ Council of Char- lottetown, P. E. Island. Gentlemkn 'j In Septenil)er, 1875, I received instructions from your honorable Board "to make a survey, and re))ort in writin<^ "the best and most economical system, and probable cost of "furnishing Charlottotown with a copious supply of water, "sufficient to meet the demand for domestic pnr})oses and "for extinguishing tires." Various circumstances have consi)ired to delay this work and keep me from making atinal Report ; chief amongst which was the boring undertaken at Mount Edward, to test the practicability of obtaining a supply from wells and the sub- sequent action of your honoral)le predecessors in reference to this and the subject generally, — actuated I have no doubt by an honest desire to promote the best interests of the City and the City's tax payers. It gives me pleasure to be able even now to Report and lay before your honoral)le Board, in obedience to your late request, the information collected in relation to this important subject, together witli my opinions and estimates of " probable cost &c." a 4 KEPORT ON THE With a view to obtain tlio necessary data, for tlie proper performance of the duties entrusted to me, I iiad careful surveys and ganging made of Winter River, and of the Gates and Curtis hroolis during the fall of l^^Tf), and the spring and summer of 187G, but it may be well before proceeding to discuss their several merits, and estimate the probable cost of each, to devote a few pages to some GENERAL CONSIDERATIONS which are more or less common to all systems of water supply, and to a proper conception of which at the outset, much of the success of undertaking of this sort depends. The ground which must be gone over ii: this connection will not be new to such of your citizens as have given attention to the subject, but to those who have not had an opportunity to study the several questions involved in a good water supply, a few preliminary remarks may not be un- interesting and may help them to form correct views as to the principles and practice which should prevail in all public systems of water supply. A primary and highly important consideration in connection with this is the SOURCE OF SUPPLY. This is a question of vital interest, and should be carefully considered before coming to a decision ; as an error in this respect may lead to a vast nmount of mischief, besides a needless waste of money. A good source of supply should be able to furnish : — (1) An abundance of water for every purpose at all seasons of the year, and (2) The quality should be such as to fit it for manufact- uring and family use, as well as for ordinary, municipal purposes. <'. WATER SUPPLY. 5 tion ; iill fact- ;ipal In relation to the quantity which a stream or otlier source of supply may he capahle of furnishinir to meet the daily wants of a City, two (juestion.s arise, vi/ : — what shall he the unit of supply? and what provisions shall be made for the future? Both rpiestioiis are of great practical importance. UNIT OF SUPPLY is a technical term which means the average uumhcr of gallons which should he provided diiily for each member of a community — yotmgand old. On this point there has been and still is a great difference of opinion among Engineers, as well as municipal authorities. One class says limit the supply to a reasonable amount, and by well devised and strictly enforced regulations keep it from getting beyond this ; whih^ another says, why limit that which is so essential to life and health and comfort? Furnish water to all without stint or limit : give it freely, cheaply, copiously, that all may learn to wash and be clean. And there is no doubt ihe drift of ])u))lic opinion is towards the latter view ; and that too in a marked and unmistakable manner, as will appear from a few well authenticated facts connected with this branch of the enrpiiry. As the circumstances and social habits of Cities are never exactly alike, no definite rule can be given for finding a "unit of supply." Each case must be judged independently, and the conclusions at best are onl\' approximate ; but in this as in everything else that effects our future well-being, it is w^ise to err on the side of safety, and make an ami)le allow- ance at the beginning, — even at a considerable increase in first cost. In old times when the sanitary value of water was less known and appreciated than it now is, from five; (5) to ten (10) gallons a day were considered a liberal miit of sui)i)ly, and fifteen (15) gallons were spoken of as extravagant waste. Then however City supplies were mostly intermittent and 6 REPORT ON THE much of tlio water used was timwn from "stand pipes" exposed in courts or otlier open places for cominon use. Maths and water closcls were <;en('rally speaking unknown, and few had leai'ned the vahie of water as a labour savinu: as well as licahh i)reserving ajjencv. The gradual introduction of the constant snpph/ system — enh'ghtened views in relation to the l.iws of health — to better modes of drainage — to the domestic value of batlies d water closets — to the saviuir of labour ellected, when an water, (hot and cold,) could be drawn in the stable, the scullery and the kitchen, as well as in l»ath rooms, dining rooms and bed rooms every hour of the twenty-f»)ur, {'2\) combined with a growing demand for manufacturing and municii)al purposes, — has hid to a unit of supply not dreamed of forty (40) years ago. At the ])ei-i()d named the unit had risen to thirty (30) gallons, and this was really in excess of what ex))erience then showed to bo the actual consumption. This was the unit adopted by the able and experienced engineers who planned the Crotou works for the supply of New York ; and was believed to be not only ample but sumptuous and sutHcient for every possible use to which the water could be applied. Under this impression the works were designed and exe- cuted, with a su])posed ciipacity to meet the wants of the City for twenty-five (25) or thirty (30) years, but they had not been in o[)erati()n tcMi (lOj years, when it was discrovered that it would be not only impossible for them to do this, but to maintain the supply to a poi)nlati()n less than one-half of that originally contemplated, further expenditures of millions of dollars would have to be made. The experience of ]Sew York in this respect has been the experience, to a greater or less extent, of Boston, of Brook- lyn, of Philadelphia, of Chicago, of Detroit, of Hamilton, WATKR SUPPLY. ot'Toroiito, ol" Moiilrojil, of lliilif:ix, Jind of Siiint John : iiiul ill sliort of cvory place of iioto liuving ii public wjitcr siii)ply. The historv of one is the history of all. Under the constant sn[»ply system, (which is the only one 6ver thought of now) the daily per ca^ 'ta consumption has advanced steadily, till sixty (tiO) gallons is now aecc^pted as a moderate average; and the indications are that it will yet rise above this, as will a[)pear from the following recent rates of c()nsnni[)tioii, taken from reliable sources : Gvij.o.xs. <;ai.i,<)ns.

At some seasons of the year, when the weather is very hot or very cold, these averages will rise considerably above the figures given. During the midsummer months, for in- stance, water is often allowed to run freely to keep it cool, — for cleansing sewers, — creating currents of air to remove bad odors, — sprinkling streets, — for Avashing sidewalks, windows and carriages; while in winter it is used co[)iously to keep imperfectly protected tittings from freezing : a con_ stant run of water being an easy and elfectual remedy, when drains exist to carry what is thus wasted quietly aud quickly away. I 8 HEPOliT ON THE The cold weather waste has hitherto defied the most strin2:ent hiws and active nioasures for its suppression. As a rule it is beyond the reach of Inspectors, and is lieaviest at times and seasons when detection is all but impossible, in our climate. The greatest waste is generally in connection with kitchens and water closets during the still hours of night, when doors are locked and secured against intrusion. It is therefore beyond control and should be provided for at the outset, if etHciency is t be maintained and unpleasant embarassments avoided. Ai.J in doing this the wants of the future as well as the present should be considered carefully. In view therefore of the experience of the past, and of the habits of our own times in regard to the use and waste of water, 1 could not reconmiend a smaller " unit" for Char- lottetown than sixty ^y^'^) gallons per day for each individual within the City's bounds ; and in doing so I feel assured that large as this may appear, it will not be found extravagant, when your city is sewered, your houses fitted up with baths and water closets, and your people have learned the use and vrduc of water as a labor saving and health o^ivinu' aijent. Having fixed on a unit of supply the next consideration is the POPULATION TO BE PROVIDED FOR, present and prospective;. For this there is no definite rule, nor can there be, as the circumstances of no two places are precisely alike. Each must be Judged by itself, due regard being given to probable futire growth. From the geographical position of some cities their growth will be more rapid tha-.i others not so favorably circum- stanced. It is prudent therefore to consider this, and when there is reason to believe that such will be the case, make ample provision for it at the outset, especially in such parts of the work as cannot be easily and readily enlarged after- ward. WATER SUPPLY. 9 111 some cases when the towns to be snppliod are small and almost stationary, scarcely any provision is needed for future enlargement, while in others by being seats of man- ufacturing industries, — ports of shi[)ment, or centres of trade and travel, prudent forethought requires that imme- diate provision be made for future expansion. There is reason to believe that Cliarlottetown from its insular position, and the beauty iv\d fertility of the Island of which it is the commercial as well as political Capital, increased facilities for travelling, etc., will grow more rapidly in the future than in the past. And though its onward progress may not equal some of the great cities of the west, yet it would not be safe in designing works for its future water supply to provide for less than double its pre- sent population, or rather double what it may be when the works now contemplated are completed and ready for use. In order to ascertain what this may be, it is necessary to take a look at the past and on the data thus obtained base estimates of the future, which will be at least approximately correct. By the census returns of 1871, the progressive growth of your City seems to have been as follows, viz : — Population in 1841 389G 4717 increased in 7 years, 821 6513 " 7 " 1796 6706 " 6 " 193 8807 " 10 " 2101 By these returns, it appears that the increase for the seve7i (7) years ending in 1848, was fully 21 per cent; for the next sev€?i.(7) years al)out thirty eight percent; while for the following .six (6) it was but 2-96 per cent; and for the succeeding ten (10) years it was 31 3 per cent. As there is no reason given in the census returns for the apparently small increase between 1855 uud 1861, it would do " 1848 do " 1855 do '« 1861 do " 1871 10 EEPORT ON THE be reasonable to consider the Hgures (ioKJ a misprint, and that the corrected number should have been 5(518. This alteration would n)ake the increase for the seven (7) years ending in 18.")5 al)out 1!) per cent, and for the six (6) y(\ar3 ending with 18(51 nearly liJ-o per cent. Corrected in this way the increase between 1841 and 1848 Wiis equal to a deccnnitd increase oi' oO per cent ; between 1848 and 185.") of 27 per cent, and iVtui 1855 to 1801 about 32^ per cent, it may be a mistake to surmise that (5513 is a mis[)rint, but whether it is so or not, the I'esult will be much the same, it the periods are combined and the whole 13 years taken as one. As it is probable — with a copious •'^iipi)ly of water suitable for domestic and manufacturing purpv».scs — that Cbarlottetown will continue to grow, Avilh a somcw hat greater rapidity in the future than in the [);ist, 1 })ropos-c to base my prosix'ctive estimates on a steady decennial incn-isc of 32 per cent from 1881 when the population of Charlottetown and Iv(/yalty should be 11, .")»]*», if the rate of inciciase h:;s been the same between 1871 and 1881 as for the picceding ^en (10) years. On this biisis the popidalion at the I'ud of each succeeding decade would be about as follows, viz: — Population 1881 about 11,625, 1891 " 15,345, (( It (( 1901 1911 " 20,255, " 2i5,736, As these estimates include what is called the lloijalttj as Avell as the City proper, the inhabitants of whirh are not likely at any time to be consumers to any great extent, and as a number of years must ela[)se b, f )re the people are led from their wells to the use of pipe water, it would not be pro[)er to consider nil as water takeis. At best — even in the City proper — a considerable time mu^t elapse l)efnre the new supply becomes general for house purposes ; and in view of WATEE SUPPLY. 11 I this it will not bo imnroper, in tryin.i? to approximate the daily consumption to estimate for a certain per centagv of the population. This, withont donbt, will be a constantly increasinu: number; tlie ratio of increase (lei)en(ling, to some extent on the relative ((ualities and economies of the new and old si!pi)lies, and the rate at which the distributing pipes are hiid through the streets of the City. For the reasons stated it may be assumed that in ISX'2, should the works l)e then in operation, that about one fourth the population would draw a supply from the City jNlains, directly or indirectly — in 104,1()0 " The approximate aecuvacy of these tigures will depend materially on the management of the works, and the demand thilT^ay be made on them for manufacturing purposes. If in the former there should be laxity and carelessne.-^s — as too often ha[)pens when works of this kind are controlled directly by City councils ; or s'loidd there l)e an unex[)ected increase in the latter, induced by the improved facilities for industrial investments, which conie of a copious supply of water suit- able for steam pin-pos< s, larger volinnes may be leiiuired at the dates given : but with proi)cr attention to inside tittings, strict surveillance and a steady deterujination to prevent 12 REPORT OX THE and suppress waste, the quantity named would be abund- antly ample for all legitimate uses, public and private. Any source therefore which may be selected should be able to furnish not less, ultimately, than from one and a half to (tvo millions of fjaUons daily; and its Avater should be suitable for manufacturinjr and household use as well as for municipal purposes. Water for MANUFACTIRING PURPOSES should be clear and free if possible, from iripurities of an earthly or calcareous character. The presence of the latter gives what is called hardness to water and makes it unsuit- able for steam purposes, and such manufacturing operations as require for their proper prosecution soft water — such as tanning, bleaching, dj'eing, wool washing, &c. When hard water is used for steam purposes, lime as a carbonate or sulphate is deposited in the boilers, with greater or less rapidity, according to the character of the water used ; the largest deposits b'.nng obtained from the hardest water. Such deposits when allowed to accumulate become in time as hard as stone, and are always dangerous and detrimental to boilers. They prevent perfect contact between the boiler and the water and cause the plates of the former to burn out rapidly, making frequent repairs necessary, and to this and cognate causes explosions are often attributed. Such incrustations are likewise bad conductors of heat, and to overcome the resistance thus otfered and i)erf()rm the same amount of work, extra fuel is required; which means extra cost, in addition to periodical losses of time and labor in stopping to " scale " or remove by hand the deposit thus formed. Manufactures seldom thrive where a reasonably soft and pure water cannot be had. This is indispensable to their success. A cheap and copious supply of water, for steam WATER SUPPLY. 13 purposes alone, has proved in other i)hices a great incentive to local intlnsti'ie.s, attractinir population and furnishiuir a ready means of ])rotital)le enipio} niciit to the youth of both sexes. Such has been the case in St. Joliu, and such with- out doubt will be the case in Chailottetcjwn also, as soon as it is provided with water suitable for steam purposes. "Water tit for HOISEHOLU USES su'^h as cookiiio-, drinkino: and washina', should be com- paratively free from oriranic impurities, pleasant to the eye as well as to the palate, aud reasonably soft, clear and transparent. But these qualities are not always obtainable ; nor would the absence of one nor all of them to a moderate extent necessarily imply an unwholesome water. Some waters are bright, sparkliujr and pleasaut, and yet emineutly dangerous, whilst (jthers possessing neither of the qualities named, are safe and wholesome. Still it is desirable that water which is to l)e used in the household for dietary purposes should be free, if possible, of everythiug of an otl'ensive character, even though it should be harmiess in itself: and no source should l)e selected which caunot meet the conditions named, to a reasonable extent at least, as it is of the utuiost importance that water which is to be used for culinary purposes should be PURE AS WELL AS PLEASANT. Purity, here is to be understood in a hygienic rather than a chemical sense : for no water is ever perfectly pure, no matter whence it comes — whether from the earth or the air. Being a powerful solvent it takes Irom everything it touches or with which it cotnes in contact. As dew and fog and rain it takes from the atmosphere organic dust and dirt ; the products of combustion, of respiration, of decaying animal and vegetable matter, zymotic germs, &c. The impurities drawn in this way make rain water frequently uutit for 14 REPOKT OX THE cooking- or driiikinir before it is filtorrd or clarifieil hy siibsideiicc and aeration. Siidi impurities are orreatest in tlje neigliborliood of cities, and least at a distanec tin-refroni. The inii)nritics whieli water derives from tlie earth dejund oil the geological ehai'aeter of the soil over which it passes, or the strata throuuh which it oernieMtes in its nroaress downward. 8honld the soil contain animal excreta, or sewage matter, the impurities derived therefrom are always dangerous; and especially so when zymotic diseases ))revail, as cholera or fever, in the district from which the water is drawn. Such impurities are frequently found in SHALLOW WKLLS, — -wells say of 20 to 50 feet deep — when placed near human habitations, and some by intiltration from neighboring cesspits and privies. The more open and porous the rock or earth is into which such wells are sunk the greater is the danger of their waters becoming contaminated, and unfortunately the poison which enters in this way is seldom detecta])le hy the senses. On the contrary, it often happens that water which is highly imjiregnated with night soil and barnjai'd soakage is bright and sparkling, and i)leasant alike to sight and taste. No such water is tit, however, for human use. At least it is never a safe beverage, as it is constantly liable to pollution, and often ?".s polluted and dangerous when least suspected. All such water should be tivoided as nuicii as possible. In relation to this class of wells, the llivers Pollution Connni*isioners in their Sixf/t and last report, say that " the sources of i).)lluti()ns around them are so general, numerous and patent, as to leave l)ut few of eighty-seven (^7) samples examined of sutlicieut purity for safe domestic use : altl!ough most of them were pure and palatable." In a great majority of the samples examined, the total solid impurity was WATER SUPPLY. 15 lo-ll •ity ivas excessive, ranging as liigli as two hundred and Jhrty (240) parls in l(l(;,()Oi>, or one hundred and sixty-eight grains per ini[)erial gallon. The organic niattei" in wellfj of tiiis kind is, as a rule, deprived from se\vj>ge, or refuse aiunad nuitter, and is, therefore, iiighly ohjectionahle. Yet such is the general chai'aeter of all city "wells, and to this cause is oftei; traceable the sudden outbursts of e[)ideniics in parti<'ular places. The lieport to which 1 have just referred is not only the hitest but is also the most com[)lete and exhaustive that has yet been made on the potable waters ofCireat Britain, and it is worthy of remark that the Judgment of the Com- missioriers corresponds with and contirms the opinions advanced by the medical professoj's of your city in reply to a series of pointed and perlinent questions submitted to them in 187(),by William Heard, Esq,, a gentleman who appears to have given UiUch attention to the question of water supply, and brouiiht to the discussion of the same a rare amount of intelligence, zeal and good judgment. For this and other information relating to the dangerous character of the shallow well water with which your city is sup[)lied at pr sent, see Appendix A. The impurities named above are seldom found in dp:kp wells, wells, say, oi one hundred (100) feet deep and upwards, when the rock through which the water percolates is free from fissures, and the surface water carefully excluded. When the water received into such wells is com))elled to filter through the surrounding strata from the surface down- ward, tlie impm-ities it contains are rendered harmless, thouiih it mav have been loailed with polluting matter when it l)egan to penetrate the ea.rth. This residt depends of course on the strata being fairly compact and porous. When opposite conditions prevail, when the strata contain numerous cracks aud chasms, through 16 REPOKT ON THE which the water may flow with little or no resistance, n» is the case in your city and n(>i_ii:hi)()i-ho()d, the inii)ni'ities received on the .surface will retain most or all of their dangerous (]ualities, no matter how dce[) the well may be. Next to i)urity in water for household purposes is SOFTNESS. This quality in a water which is to he used daily in the ordinary operations of cooking and cleansing, is one of primary imi)ortance from an economical staiidpcint, irrespec- tive of the pleasure which comes to the touch from the use of such water, and the sense of cleanness which remains when one's ablutions are ended. In the process of cookiuf/ a soft water oi)erates more readily on the soluble parts of such materials as are submitted to boiling, or to sinunering at a high temperature ; whilst in the preparation of bread, of tea and of cotiee, in the making of soups and boiling of meats, better results are reached by a soft water than by a hard one, through its greater extractive power. For this reason less time and material are required to produce an extract of a given strength and richer flavor ; and as a saving in time means a saving in fuel as well as in material, l)oth have an actual money value, though not always apparent to ihe operator. Exact an ^ elaborate experiments in cooking with hard and with soft water have shown beyond doubt a saving of time, in many inst iices of tiventy Jive (25) per cent, in favor ot the soi't water, while the color and strength and flavor of the meats, soups and vegetables were more fully and delicately brouuht out. In the making of tea most housekeepers know that a soft water is superior to a hard one for extracting the full strength and flavor, but it may not be so generally known that a given measure aiid quality of tea which would yield WATER SUPPLY. 17 when nimle with hard vvator three (3) cnps, would furnish Jive (5) of e(j[UHl strength ;ind tlavor when made with soft water. This may not appear to I)e a matter of nuuh importance, but yet 1 am satistied that the introduction of a soft water into Charh)ttetown would result in a consideral)le annual savini^ in the item of tea alone. Dr. Philip Holland found iii the course of his researches and observations that he could save eirfht (8) parts out of every eighteen (18) parts of tea, when made with water of a given softness, and that his weelily saving in this alone was equal to one half of his water rate. For fuller particulars on this point see Appendix B. But the value of soft water in household economy does not end with the cuisine. It extends to other depart- ments as well, and with still more striking results. It makes personal ablutions pleasant to the skin and encourages cleanliness — it facilitates all scouring and scrubbing opera- tions — it is less destructive to cotton or linen fabrics, that require frequent washings — and permits large savings in fuel, soap and labour. Hardness in water is caused by the presence of mineral substances, chiefly salts of lime, magnesia and iron ; and is commonly measured by what is known as "Clark's scale," — named after the gentleman who first suggested its application as a test or measure of the relative amount of hardenin": materials in different waters. It is a soap test; and the degree of hardness is determined by the amount of soap required to produce a hither of a given strength. The soap solution is prepared by dissolving hard cm'd soap in proof spirits, in the proportion of one ounce (avoirdupois) of soap for each gallon of spirits, and then tiltcjred into well stoppered "glass vials capable of containing 20UU grains of distilled water." The entire modus oj)erandi is exceedingly simplo aud all but uuiversally adopted as a comparative 18 REPORT ON THE measure of degrees of hardness. Experience, however, is required to perform the operation successfully, even in the laboratory of the chemist. By Dr. Clark's notation one degree of hardness represents as much of the hardening salts as would take up and pre- cipitate as much soap as a grain of c;irl)onat*s than one thousand gallons of water per minute, or sufficient to supply eight (8) powerful streams when needed. (2). The leading and distributing mains must be suffici- ently large to convey this quantity of water, not only to the city, but, when tire breaks out, to the place of danger. (.3) The fire hydrants should be large, well drained, properly protected, readily accessible and sufficiently near each other in the dense parts of the city to require not more than two hundred [200] feet of hose on ordinary occasious, and *i 24 REPOKT ON THE (4) The pressure should l)e sufilcieiit when a mjixiniuni sii))j)ly is rcciuii'ed to send eigJil^ or more, inch streams to a heighty//ify to sixfi/ feet, and still he able to strike the tire with eti'ective force. A\'hen such is the case each hydrant is equal to a steam fire euiiine, standing near the pcnnt of danger v»it!} steam up and readv for work on the shortesj; notice. The height named r('[)resents a hydrant pressure (according to Lexhure ami Ellis) of about fJiS to 4(5 lbs., and a nozzle presswe of 24 to 30 lbs. per s(]uare inch. The loss or ditference between the hydrant or initial pressure, and that at the nozzle or point of discharge, is occasitined by hose fricti(»ns. But there is another question in connection with this insurance business whicli should not be overlooked nor lost sight of at this time, viz: icil/ the present prej/iium rates continue? I have taken some pains to obtain inf»)rmation on this point, and 1 am satisti-'d that the present low rates caimot continue. A moderately severe tire is sure to double them, and this may happen without such a disaster. The strongest and the best companies feel that the present pri'minm rates are absurdly l<»w, auvl must either be raised or the city abandi^iied, and with a view to this some are even now, so 1 have been credibly informed, curtailing their business. The question, therefore, of an improved water supply is one of pressing importance from a protective point of view alone, and cannot be delayed indefinitely without your city paying the penalty of })rocrastination in some form or other. Insurance companies may be generous for a season, but they cannot continue to ignore the law of average with impunity, and are too intqlligeiit and keen sighted to do so beyoud a limited time. A general increase, I have been WATER SUPPLY. 25 assured on reliiiblc authority, is sure to follow in a relatively (■hort time it' your eity resohcs to leave its water supply us it is.

Having noticed with more or less fulness the leading features of a desirable water for a city like Chailottetown, in its sanitary, in its protective and in its economical aspects, a brief resume of general results, or conclusions dedncible therefrom, may not be una[)pr()priate before proceeding to consider the claims of the various sources of supply, and the probable cost of each. And fiom what has been said the following conclusions nuiy be fairly drawn, viz : ( 1 ). That the water sup[)lied from the shallow wells of your city — surrounded as they are with cesspools and privies, and subject to pollution from surlace soakage, is not only bad, but positively dangerous, and wholly unfit for lunnan use ; and by reason of its hardness, detrimental to the manufacturing interests of your city. (2). That a new supply is in«lispensal)le, a pressing necessity, and should be obtained at almost any cost and M'ith the least possible delay. (o). That the source selected sh' nld be able to furnish a water that is fairly soft and sparkling, j)leasant to sight and taste, free from organic .impurities and ca[)able of furnishing an immediate supply of about 7a(),iMiO gallons daily and a prospective one of fully twice this rpiantity. (4). That the new supply should be a constant service one and delivered at high pressure, so that the water would rise WATEE SUPPLY. 27 freely to tl'o upper stories of houses in the highest parts of tlie City, and have sutHcient force and vohnnc to be eifective in the sui)pression of tire without the help of Eiia'ines.

That the iirc hydrants sh(»uld be sufficiently hirge and ch)sely set in the principal parts of the City, that not more than 200 feet of hose would be required to reach an ordinary tire. (7). That a supply of water like that now contemplated would condu(;e to the general healtii of the City, and prove a great protection against diphtheria, fevers, cholera and other virident and fatal epidemics. (8). It would allow the streets to be thoroughly sprinkled in dry windy weather, and the supi)ression of dust would add to the sweetness and purity of the atmosphere, to the comfort of citizens and to the protection of goods exposed for sale by shopkeei)ers and others. (9). It would permit sewers and gutters to be freely flushed and flooded with water in hot summer weather ; les- sening thereby the cost of your scavenger work, and adding to the , and the saving in public wells is $142 less than the average annual ontl.iy for three years just named (14. ) The above figures show an average annutil outlay of fully $13.32 per family as the cost of their present imperfect WATKR SUPPLY. 29 water supply, or the interes^t ui (! per eenl, on a cjipital outlay of upwards of ?4-!4.0()(), which is t'cpial to a (•ai)ital expendituri' per family of $'2-2'2, or a per eapita outlay of Sio() fully for each tnan. woman and child of your eonuuuuity.

Having pointed out the [)rinci[)Ml features of a gcxxl water supply and some of the bcnelits that come therefrom, it will be in order now, to consider brietly the spe<'ial claims of the several soui^-es nanu'd — the tihicss of each to meet the pres- ent and future wants of your city — the class of works necessary for its utilization and tlic '|)r()hal)lc cost'; exclusive of distribution.

The artesian or det'p well scheme was looked on witti favor by a large number of your most intidli^cMit citizens, in 1 contractors. This work, I deem it ihut to myself to say, was not under my supervision, nor was !inv report nuide to me dui'ing its progress. In a report submitted to your city council in 1878, jNIr. Pickard says he had found several "large veins of water, "but the open character of the rock prevented it from rising "to the surface. That from the same cause, even at a far "greater depth a flow of watei- in any quantity cannot be expected," t)cc. Nothing has been done 1 believe since this report was written, and if 1 am correctly informed the w(u-k was abandoned, in consequence of a drill having been lost irrecoverably in the hole at the depth above named, 4118 feet. To this depth, at least, it seems certain, there is no such volume of water to be had as would be necessary to supply your city, and a further fact is l)rought out, that has proved destructive to many similar etl'orts — namely : rents in the rock, by which the water appears to escape, and Hud outlets in other directions. This is no unconnnon obstacle to success in the new redsandstone, and to this and kindred causes are chietly due the many failures to lind water, recorded of this formation. I do not know that you mean to do more than has been done alreatly for the settlement of this question ; but I could WATER SUPPLY. 31 not aclvisi; niiy further t'Xi)oiRlitiii(( in this way, us I see no gootl grouiid tor htdicviiig in I'litiire success. The str.ititiciilion of the rock, iis well as the iiiinierous cracks and fissures with which It .ihounds and the great uncertainty of getting a nfi((hle water, even if found in ahuudance, lead nie to tliink ii would be injudicious to look to wells of this character for th(^ futui'c supply of your city. Many of the s;and stones whieh surround and underlie your city are poi-ous and some of them a gooii deal jointed. I'lider such conditions it is not unrcasonahle to believe they may be permeated by sea water. WINTER RIVEK. liy the surveys of 187(i this river was found to have an elevation, at what is known as the " Henderson" mill site of 107 feet above high w^ater at Charlotletown, or 57 feet above th(^ highest point of land in the city propci* ; and at a point on thc"Col)I)" or " Bryanton " farm (say one mile lower down) an elevation of 74 feet in round numbers, or 24 feet above the highest point in the city. The area of the water-shed above the last named point is al)out 3,100 acres; one half of which discharges above the Henderson Mill site and one half below it. The Alatthewson Mill dam is about one and three-eighths of a mile farther down the stream than Cobb's and is about 70 feet above city datum. The water-shed between Cobl) s and .Matthewson's has an area of about 2000 acres, or say 5000 acres in all. By the erection of a dam at Cobb's of about 10 feet high and 2G4 feet long, the surface of the stream could be I'aised to 8() feet and a reservoir obtained with a surface area of about li> acres and a storage capacity of about 8,(JO0,000 cubic feet or 27,000,000 gallons. The tlow of water in this stream is pretty steady but like all other streams it is affected to a greater or less extent by the character of the season. With a view to approximate 32 RKPOUT OK TIIK the How, Aviei's were? t'lHM'lid at IIi'iiiliTsoii's, Cobb's iiiitl iNbiltht'Wsoii'.s for sjoiiic wct'Us (hiiiii;r the fall of 1'iii_a.s made diiriiiir the Aiidiiuii iiiciiths show a greatci" (lischariic than do thosi' of the spi'iiii; and snninu'r, the rain fall havin,i»' been heavier.

At the (.'obb wier the daily diseharge oscillated dnring Angnst and Septeml)ei', when the streams were lowest, between 2,0(16,000 and 1,007, 000 gallons [)er 24 honrs. Xo observations were mule dniing 1876 at the Matthewson dam, as the volnme of water flowing thei-e — the prodnet of the entire drainage aiea — is beyond d()id)t am[)le for all the legitimate wants of a popnlation from three to four times greater than now resides in Charlottetown. The water of this " river " is elear and soft and [)leasant to the tasic;and ap/})ears to possess all the essential elements of a water well titted by natnre for domestic and mannfactur- ing [)nrposes. Froni the character however of some portions of the collecting gronnd there is reason to believe that it may be subject at times, when heavy I'ains prevail, to more or less discoloiation ; but though this mtiy render it for a time slightly unpleasant to the eye there is no reason for believing that it would otherwise impair its quality. This is a i)oint on which then; is great unanimity of opinion between the chemictU and medical authorities of Europe and America. / WATER SUPPLY. 33 "ving Winter River lies in a nortiietisterly direction t'romtlie city and l)y the nearest available route is about five ami a half (5^,) njiles distant from the Provincial Colonial Buildings. Its soiu'ces jirc on the northern slopes of the high land that stands between it and the city, and it follows a northeasterly course to the (lulf of St. Lawrence via Bedford Basin. As the summit of the ridge just named is about 18G feet altove high water or lOU feet higher than the suggested "• Cobb" reservoir, to make its water available for city use pumpiiKj ov tunndiiny would have to be adopted. By the former (pumping) the water would be delivered in the city with a high pressure force ; that is to say from K.O to 13() feet (or more if desired) above your highest city level, and the whole of the impounded water would be available in dry seasons, should the natural tlow ha[)pen to be less at any time than the city's daily consumption. By the latter or tunnellinij: the water would be delivered at from 3U to 3(5 feet above your highest city level and about 24,000,000 gallons of the stored water would be available in seasons of extra drought. The " lift''' or difference of level between the pumps and the summit of the hill would be about 100 to 120 feet; and the water could be sent direct to the city, by gravitation. The lengtli of the lifting or rising main between the pumps and the reservoir, would be about 7000 feet and the length (»f the leading main from thence to the city about 21,100 feet. Both siiould be made of good cast iron and neither should be less than 12 inches in diameter. Indeed it would be better if the risins: main were larijer than this. A 12 inch pipe drawing its water from a reservoir at this height and discharging at a point 25 feet above your city datmn, or midway between your hiiihest and lowest levels, should deliver, if [)roperly laid and graded about 2,00J,'J00 galloua daily or 83,333 galloua por hour. u REPORT ON THE The pressure under uhieh this discliiirge would lake plaee would be well lilted tor tire purposes, irlfhont the (tul of engines; hut niueh niori; than is necessary tor oidinary daily use; a medium pressure heiiig uu)r(^ easily manaus four hundred thousand (2,400,000) gallons of water to begin with. To do this it would require to have a solid capacity in round numbers of a rectangular body liiO feet long by ^0 feet witle and 25 feet deej). Tart of the work of construction would be in excavation ai.d part in embankment. The engines and pumps should be able to i)lace in this reservoir about 50,000 gallons per hour or GOO.OOU gallons per day of 12 hours; and the engine house should be suthciently roomy to accommodate a second engine should such be deemed requisite in years hence. The lengih oi tunnel required to biingthe water of Winter River to the city would not be far sh(irt of 2^ miles and may possil)ly exceed this ; and the length of iron main about J 0,500 feet. The dimension of the tunnel could scarcely be less than 4.5 X 6 feet. This are;', is not required for supply purposes l)ut to give ordinary room for mining and removing of the debris. Shafts will be leiiuired along the whole line of tunnel, one probably every (iOO feet, for ventilation and the removal of excavated material, and it may be for pumping should water be met with. The average depths of these shafts will be WATER SUPPLY. 35 the be about 50 to (50 feet aiid ouch one will roqiiiro a set of lioisting inacIiiiuMy, Nvorkod Uy steam or horse power as may prove most economical. • As the new red sand stone in the neighborhood of your city is [)()ron.s and Jointed, it is not improl)al)lc that a part or the whole of th(! tmniel would have to be lined with brick, to iit it for the duty it would have to do; but this is a circumstance that can only be found out as the work progresses. The additional expense incurred in this way may bo much or little and may reduce or add consider ibly to the estimated expcmliture. Work of this sort is always surrounded with doubt and uncertainty as to tinal cost, anj r(M|uires a larger margin than ordinary undertakings. Gale chambers and gates will be required at each end, to regulate the flow; and at the city end, at least, substantial strainers to intercept the fish and prevent them from entering the main pipe. These chambers need not be large but both should be in duplicate and the arrangement such that either could be shut oft* at pleasure and cleaned without disturbance to the ordinary daily supply of the city. The supply of Avater derived from Winter River in this way would be an eminently low pressure one and useless in a great measure for fire purposes without the aid of engines. It would be a fair presstu'e however for ordinary purposes to the greater part of the city, but might not be uniformly satisfactory to dwellers on the summits. A 12 inch main lending from the termination (jf the tunnel to the city and discharging at a point 25 feet above city datum should deliver when new and well laid about 1,5!)0,000 gallons per day or Ofi, 250 gallons per hour. This it will be observed is greatly less than the quantity obtained from a i)ipe of the same size discharging under the superior pressure of a sumnn't reservoir. To got the same results in gallons of water brought to the city daily, a pipe of not less 36 IIKPOIIT ON THE than 14 inches diaineter would have to be laid between the city and the tuiniel. The course of tuMuei and pipe are shown approximately by full red lines on thencconipan)iiig plan, subject of course to revision and change should location surveys ever be made, which is rather doubtful.

Proceeding in a northwesterlv direction about 3 miles from the Gates gauge, the Curtis brook and Mill dam are reached, and here there is a fine flow of excellent water, which ap- pears to be well suited for city purposes, being soft and clear and pleasant to the taste. The bed of the brook between the bridge and the mill dam is not mnch above city datum, but proceeding upwards for about li miles a point is reached which is 54 feet above WATER SUPPLY. 4o 4,421 5,720 G,433 > 2,153 high water, or 4 feet hiirlier tlian thf^ highest hind in the city. It was nt this point (markod on plan) the ganges were phicod and ohservati(»ns made on the volume of water flowing dail}' in tlie brook. The surface water-shed of this hriiok is about 2300 acres ; 1400 of which are helov the gauge and about 1H)() above it. It was apparently from the last named area the water was obtained which passed over the Curtis wier : but from the fact that with a li^re.itlv diminished draina<;e area the flow was greatlv in excess of that ol)tained at tiie dates gauixe and relatively greater even than that obtained on \\'inter liiver, there is reason to believe that a portion at least of the water which comes to the surface in tliis valley comes from sources beyond the sunmiit ridges, that outwardly deiine the water-shed ; in other words the hydrographic basin is more extensive than is shown by the surfaces area. The greatest daily flow o])serv<'d was 1,712,800 gallons in June and July 187() and the Invest 7 1!), GOO gallons in Aujxnst of the same vear. The average daily discharge during the continuance of the observations in October 1875 was l,3(i9,5)00 gallons and for June, July and August 187() al)out 1.2;')5,OO0 gallons. The former represents an average d;iily discbarge per acre of about 1520 gallons and tlu' latter of about 1370 gallons. These estimates and observations, like the others, are only ap[)r()ximate, and so far as they go do not, 1 think, over state the ease. These flgures :«how that the Curtis' brook has a much more steaily and equable tlow than (lates' brook or ^Vinter river, and is less direcih/ afl'ected by the rain fall. This trait favours the theory that tlie water found here comes from deeper and more distant sources than that which appears in the '• Gates Valley " and makes it more suitable for city purposes. 46 REPOKT ON THE To utilize tliis water a storage reservoir woultl have to be created al)ovo where the gauge stood. This could be doue by placing a dam across the valley, a short distance below ■where the nieasununonts were taken. The banks on each side are favourable and would permit an embankment fidly 35 feet m height, at its deepest part. Bv a dam of this height the surface water of the reservoir would stand about Hf) feet above high water, or 85 feet above your 50 feet summit ; and its capacity would be about 17(),000,0()() gallons, about 147,»)0O,O00 gallons of which would be available in dry seasons and still leave a fair head pressure. I would feel some uneasiness however in placing a reservoir of this capacity in this valley ; not that the embankment, in itself could not be made secure but as to the effect this large body of water would have on the substrata — whether the overlying soil would be sufficiently compact to retain the water and keep it from wasting by percolation, as well as by evaporation. I do not know that there is any substantial ground for this fear, but still I name it as a point that should receive careful consideration before a work of this kind is undertuken. This remark applies to the Gates as well as to the Curtis reservoir. The circumscribed collecting ground surrounding this reservoir is unfavourable to its selection had it no other source of supply beyond what appears on the surface. But as alreadv shewn there is strong reason for believing that it has other and wider sources of supply ; and o'ltside of this a large part of the drainage area of Winter Eiver (say 1800 acres) could be turned in this direction, were the water of this brook required to furnish a direct supply, or only a supplemental one to the city. A maximum cut of about 18 feet deep would be required for this purpose, and the new district or drainage territory is shown approximately by blue shaded lines on the general map or plan. "WATER SUPPLY. 47 About 7 miles of cast iron pipe would be reciuirod to bring the water of tiiis brook to Charloltetown and tlie «izc should not be less than 12 inches. If this source l)c selected 1 would prefer a lai'ger main than this for a part of the way at least — a pipe say of about 10 inches in diameter for about half the distance. Assuming the point of delivery in the city to be at the junction of S[)ring Park Koad and Euston Street or 25 feet above high water, the dilference in elevation between this point and the Curtis' reservoir would be 6(< feet ; or an average fall when the reservoir was full of 8.57 feet per mile, and of 6 feet when drawn down to its assumed mininum of 67 feet above city datum. A 12 inch pipe would deliver when new and well laid about 40,000 gallons per hour under its maximum head and about 33,750 gallons under its mininum of 6 feet per mile. The former is equal to a daily supply of 960,000 gallons and the latter to about 810,000 gallons, each 24 hours. A 16 inch pipe discharging under the first named head would deliver 83,700 gallons per hour and under the second or lower head 70,200 gallons — the former being e(pial to a daily discharge of 2,008,000 gallons and the latter to 1,684,- 000 gallons, per 24 hours. By laying a larger sized pipe next the reservoir a higher duty would be obtained from the 12 inch pipe than is given above and in after years when the city s wants outgrow the capacity of a single main the supply could be increased by laying a second pipe from the city to the termination of the larger one, whenever this might be. In the following estimates of "probable cost" I have assumed that one half of the whole pipe required for this scheme would be 16 inches in diameter, or pipe equivalent theretOi 48 llEPOKT TU^ OK The estimiit(»l cost of the works r(M|uireil to iniiko tliin source availiiblc lor City [)urpo.scs.

So far as the American cities are concerned the particidars of capacity, consumption and cost have been culled from official Reports of 1878 and 1879, and the populations have been checked as far as practicable by recent census returns. The maxiunmi daily capacity, when steam or water power is used, is the combined capacity of the pumps, and in gravitation works the greatest capacity of the leading main or mains. Had the enquiry been as to the relative cost of steam or water power and gravitation, the annual cost of pumping would have had to be cai)italized to contrast fairly the merits of each as to economv &c. ; but as the tables were constructed to show simply the outlays made by cities for suitable water supplies, the annual costs of pumping and maintenance have been eliminated. The information on which table No. is based was obtained fr.)m a parliamentary "Blue Hook," published by order of the British House of Commons, in July 1879, and entitled '* Urban Water Snpphf." The particulars generally relate to the latter half of 1878, and enibraie returns as to the supply of drinkal)le water, and 7. By a careful inspection of this table it will be seen that your city is not so unfavourably circumstanced in regard to water as some are WATER SUPPLY. 09 disposed to lielicve ; hut lias, on the contniry, the natural of the ur city erages fai'ih ;lleiit hu'ilitiesot ootainn)«j: tor itseli a hountiriil snpply or cxcelleiu water, at a cost far heh)\v the average of what is paid for similar works in England and America, whether the price l>e measurcid by per capita cost, or capacity of daily supply. Having discussed, however, to a greater extent than I at first contem[)lated, the several points involved in a consideration of the " best and most economical system of furnishing Charlottetown with a copious su[)ply of water," as directed by your honorable Board, n brief resume of the salient features of each of the schemes may forma fitting and useful closing to this rather lengthy Report. WIXXr.R UIVKU. (No. 1) Gravitation and Tunnelinff. To make the water of this river available in this way a dam is recpiired .it Cobb'ti about 1«> feet high and 2fi4 feet long, to raise the water to 8G feet above the city datum. The area of the reservoir thus created woidil be 19 acres and the storage capacity aljout 2,700,000 galhtns. Water of excellent quality, but sul>ject at times to discoloration. (Quantity of stored water usar)le in dry seasons about 2,40<),Ot)0 gallons in addition to the natural fiow from the collecting grounds abov(! the dam. Length of tunnel about '1\ miles and of 12 inch iron pipe — from outlet end of tunnel to the city — about 1(5,500 feet. Estimated discharge; from pipe, at a point 25 feet above high water, about ()(>,250 gallons per hour, or 1,51)0,000 gallons per day of 24 hours. Extreme elevation of reservoir when full, above city datum about 8(> feet, or 'M\ feet above the highest land in the city. Estimated probable cost with 25 per cent, of the distributing pipe laid $213,51(«.00 and with the whole of the last named pipe laid $256,385.00. The great and uncertain cost of this work, combined with the fact that the supply ubtuincd in this way would be at 70 REPORT ON THE best a loio pressure one, and as such floficieiit in protective power, do not commend this scheme to my judgment, nor could 1 advise its adoption uidess as a hist resort. (No 2) Pumpinjf hy Steam power from Winter River, dam and reservoir the same as for Xo 1 se!»eiue. Cai)acity of engine and pumps .W, 000 gaUons per hour, 1,200,000 gaHons per day of 24 hours.

Water to be lifted 100 to 120 feet and placed in a summit reservoir for distriI>ution. Contemplated present capacity of reservoir about 2,400,000 gallons and increased in time to 10,000,000 or more. Elevation of reservoir above city datum 180 feet, or 13(5 feet above the highest point in the city, giving an effective hi(jh pressure supply for tire purposes without the aid of engmes. Estimated capacity of 12 inch main discharging at a point in the citv 25 feet above hi«rh water, about t(3,3.'33 ijallons per hour, or 2,000,0i>0 gallons per day of 24 hours. The difference between this and the power of the pumps to be made up on extra occasions, as tire limes, from the surplus stored in the reservoir.

This scheme appears to meet fully the requirements of your city in respect to quantity, quality and pressure for fire piu*[)oses, but the distance of the pumping station from the city (5^ miles) is a serious draw bick to its adoption. It is recommended however to your favorable consideration. gates' brook. (Xo. 3.) Hy (/ravilation. To make this source available by graviUition, a dam would have to be built at a point in the WATER SUPPLY. M valloy about ^ of a niik' above the Gates' Mill. Hei<^ht of dam M4 feet and length (JoO feet. The reservoir thiisereeted wonUl How about 21 acres of land, and contain when full jibout i)7.(t()(),00() irallons ol water; but less than half of this would 1)0 available for city use in dry seasons, when the natural How of the stream fell below the daily draft in the eiiy. And there is a doui)t about the prudence of trusting a reservoir of this depth and capacity in this valley. The surface water of this reservoir when full would be about (52 feet above high water, or 12 feet only above the highest land in the city. This would l)e an eminently low service supply and would be of little value for tire i)urposes, without the aid of engines. A 12 inch main laid from this reservoir to the titv would discharge at the 2;") feet point already named about 43,lM)t, gallons per hour, or 1,050,000 gallons fully per day of 24 hours, when working under a lull head, but this quantity would diminish as the water in the reservoir fell. The estimated probable cost of this supply is $f<0,7K^.OO with 25 per cent, of the distributing pipe laid, and $128,583.00 with the whole of this pipe laid. As the sui)ply obtainable for this source by gravitation could not be otherwise than unsatisfactory, I cannot recom- mend it to your serious consideration. (Xo. 4.) Pumping hij s(eam power from station F. The leading features of this schenu? are the erection of a dam of about 20 feet in height and 51G feet in length, on the site proposed for Xo. 3 s dam, and the creation thereby of a storage reservoir capable of containing about 34,800.000 gallons of water. The water thus impounded to be led by an iron pipe or brick aqueduct, to the pumping station at F and forced from thence into a reservoir on College Hill or vicinity, and taken therefrom to the city by a 12 inch cast irou luaiu for distributiuu. 72 REPORT ON THE The whole of the water impoiincled In the stora<(e reservoir W(jukl be avjiihible for eity use in dry seasons; and if in the progress of time the wants of the city exceeded the snpplying capacity of the (jatct-' valley, the waters of the Curtis brook and about 1800 acres of the Winter River collecliiiij: grounds could be brought, by a moderate outlay of money, to the pumi)ing station at F. It is not necessary to point out now how this could l>e done, as its realization is probably far in the future, but a reference to plan Xo. 1 will show its practicability, and this is a strong point in favor of the Gates brook and station F. The proposed College Hill reservoir is to have a capacity of •2,400,000 gallons to begin with, and an elevation of about 100 feet above high water, or ,)0 feet above the city summits. The pressure obtainable from this reservoir would be an excellent one for daily use and a fair one for Hre purposes, but greatly inferior to the pressure obtainable from the summit reservoir of Winter Kiver. The capacity of the engines and pumps woidd be the same as on Winter liiver, viz: 1,200,000 gallons per day of 24 hours, and the ealculatetf discharge of the 12 inch main at the assumed level of 25 feet above high water about 11(3,666 gallons per hour, or 2,800,000 gallons per day of 24 hours.* This stjition can be reached readily from the city and possesses superior advantages for the lauding of coal or fuel direct from the river. The estimated probable cost with 25 per cent, of the distributing pipe laid is $89,002.00 and with the whole of the distributing pipe laid $131,872.00. This scheme recommends itself strongly to my judgment as one that is worthy of a careful consideration before comino: to a final decision. *A 10 incb pipe under the same conditions would deliver about 1,700,000 -gallons per day of 34 hours, and if substituted tor tbe 13 iucli oae wouid reduce tbe oost about |l.iOO.OO.

By this arrange- ment no reservoir would be retpiired, but the pumps would have to l)e run day and ni.i»lit without ceasing, and to guard against intennplion to the usual daily supply by accident, the engine and i)nmps should be du[)lieated. Under this system any desired i)ressure for ordinary or extraordinary occasions could be had, but the duplication of the pumping machinery and the constant working of the pumps would add consideral)ly to the rumiing ex[)ense8. If land of proper elevation for a reservoir can be obtained near the city, one of thiu'ugines could be dispensed with and the working time reduced as at station F. and Winter Uiver. This station would be still nearer to the city than that of Xo. 4, and would [)osscss ecpial if not greater facilities for the water carriaije of coal and other materials. The water of the storage reservoir would be brought to it l)y an iron pipe or brick conduit, as may be considered best hereafter. The estimate is for the former, that the head or pressure from the reservoir may bo utilized in [)unjping. And if on mature consideration this station and system of supi)Iy should bo adoi)ted, the Curtis' Brook and Winter Uiver water could be made availal)le here, as well as at Station F. The dam and storage reservoir in the Gates' valley woidd 1)0 of the same size and ca|)acity as described in No. 4, and the whole of the impounded water would be available in dry seasons. The estimated " i)robable cost" of this system with 25 per cent, of the distributing pipe laid is $10(),5U2.0U and with the whole of the latter laid $141»,372.00.

The same dam and reservoir would he rc(juired for this as for No.s. 4 and 5. and like the former the water w>)uld he forced into a reservoir placed on College Hill or some equally elevated and convenient spot, if such is obtainable. This station is less desirable, however, than either of the others, as it is doubtful if the su[)p!rmental supply already alluded to as obtainable in the distant future, from the Curtis' Brook and Winter Kiver, e.iuld be ma le so easily available, and the cost of fuel woul 1 bej^inereased by extra ciu'taue. It is also firther from the city and more exposed to damage by the l)ursting of the nservoir, should such an untoward accident ever take place. The siipi)ly as well a^ the pressiiK' obtainable in the city would b(^ the same as in No. 4 scheme, and could Ijc increased in a similar way.

To make I he water obtainable here available, a dam 35 feet high and 107 ) feel long would have to be built, to raise the water 85 feel above city datum. The reservoir thus created would Hood about 55 acres of land and impound about 170 millions ;)f gallons, 147 millions of which would be available for city use, in dry seasons, should the ground prove sutliciently retentive under this body of water. When the reservoir was full, the daily discharge fr<)ni the mains proposed to be laid would be about 9(50,000 gallons per day, or 40,000 gallons per hour, and when it had fallen six feet, about 810,000 gallons; diminishing steadily as tho water in the reservoir fell.

In conclusion I beg to say that I am not prepared to recommend any of the gravitation schemes as suitable to vour circumstances. Tu my judgment the best and most economical system o^ water supply for your city, is to be obtained by pumping from Winter Kiver or the Gates' Brook. My present inclination is to the latter from station F. on line No. 4, but before coming to a tinal decision a careful revisory examination should be made, and exact information obtained as to suitable sites for reservoirs — cost of land and water rights — pressure considered necessary for the extinguishment of tires by your tire department and relative economy as to the convcivance ol fuel and other material to the several pumping stations named. Your city has a choice of sources and systems, and the selection should fall to that one which will give the best results in completeness and economy.

They show (hat in every epidemic the mortality varied directly with the intensity of the excremental pollution drunk by the people. Dr. W. Farr, F. R. S. in a Utter to the Registrar- General on the cholera visitation of 1849, showed by statistical tables "that in Lambeth which was supplied partly by the Lambeth and partly by the S.)uthwark company the deaths from cholera which were 1618 in 1849, fell to 904 in 1854. In 26,000 houses supplied by the Lambeth company the deaths were 294, whiist in 40,000 houses supplied by the Southwark company they were 2,248> In the houses supplied with comparatively pure water the deaths from cholera were 40 per 10,000 of the inmates, while in those supplied with foul water, the deaths were 130 to 10,000.

R. S. medical officer of the Privv Council testified to " dangerous qualities of water supply which chemists were wholly unable to measure. *** In the old epidemics when the south side of London suffered so dreadfully from cholera, the great cause of the immense mortality there was the badness of the water supply then distributed to those districts of London." Cominorto another cholera epidemic Mr. Simon says it is now a matter of notoriety within the ai'ea of another water company in London. the jwpulation last year suffered very dreadfully from cholera, I refer to certain Eastern parts of London ; cholera in high development was confined to those parts, and those parts of London were in the area of one water company. And what makes the case the more remarkable is, that not the whole area of this water company suffered, the company gave two waters and the high cholera mortality was apparently restricted to those parts of London which received one of those two supplies, so to speak to half the district of the East London water company. The source from which the company supplied this half of its district was a source peculiarly exposed to contamination from a foul part of the river Lea. The contamination was sewage. Speaking broadly for the whole metropolis the area of intense cholera in 1866 was almost exactly the area of this particular water supply, nearly if not absolutely filling it and scarcely if at all reaching beyond it. The waters of the Sonthwark and Vauxhall company were submitted to microscopical and chemical examination by the ^'■committee for scientific enquiries" and the foulness they say was almost incredible. It swarmed with infusorial life and contaiued unmistakable molecules of excrement. *** 92 APPE!N^DIX. The tenants of the Lambetit and the Soufhimrk companies were not set in different parts of the sonth of London area each isolated from the others. On the contrary tlic two p(^l)nhitions were so to si)eak mutuidly interfused. *** It likewise deserved notice that the materials for comparison were not on a small scale. It was not villMC)d) from that to the 20th tJilrti/- one; and fr()m this to the end of the month ten; making the total number of deaths from cholera in this limited district six hundred and ten ((510). **** TJio west<'ni half of Broad Stieet which contained pulMJc pmnps was the centr'i of the infected district and starting fiom thence a person walking at a moderate pace in any direction would have got bevond its limits in three minutes.**** 94 APPENDIX. A special examination of the cesspool and drains belong- ing to the house No. 40, Broad Street, immediately adjoining the pump just mentioned, proved conclusively that the contents of the former gains direct access into the well supply of the hitter. About seventy-eight hours before the great outburst a child was fatally attacked in this house with diarrhoea, and its dejections were poured into the drain which ran within 2 feet 8 inches of the well. Yet the water of this well was in great repute for drinking pin-poses. Its use was very general, from choice on the part of some, from necessity on that of others.**** Dr. Snow, of the Cliolera Inquiry Committee, thus sum- marizes the connection between the well and the siulden choleraic; outbursts just noticed, as follows : 1st. That the outburst, properly so called, wa** principally confined to the area about the Broad Street pump. 2nd. That 01 out of 73 persons who died during the first two days had been accustomed to drink the pump water, either constantly or occasionally. 3rd. That the water was used many other ways, and might so hiive bsen taken in cases when its use in the ordinary way could not be distinctly traced. 4ih. That in the workhouse, where the well water was not used, on]y Jive deaths occurred, whereis 50 would have been the ratio pl'oportif)nate to that of the neighborhood around. 5th. That in a factory employing 200 people, whore the water was drunk daily, 18 people died. 6th. That 70 men employed in the brewery in Broad Street never drank the water and escaped cholera. 7th. That in a number of IndividMal instances, which were particula ly investigated, the drinking of the water was followed by cholera; in one case a lady living quite away from the district who had the water sent out to her ATPENi^rx. 05 the road lich ater uite her died after drinking it ; her niece also died under the same circunisl antes. 8th. That at any point decidedly near to a pnmp, the mortality from cholera as a rule ceased.*** 9th. That in a particular street containing 14 houses, the onlyj^our that escaped, without a douht, were those in which the Broad Street water was never drunk. 10th. That the water was used for drinking purposes only, and was used cold. **** That it must have heen not merely generally contaminated hy cesspool drainage, but especially with the evacuation of a cholera patient. After adding an overwhelming amount ot evidence showing the malignant intiuence and constant danger attending the use of shallow well water during cholera epochs, the Report proceeds to show how TYPHOID FKVEU IS PKOPAGATD BY WATER. The pois(m of typhoid fever, like. that of cholera, exists in the evacuations of persons suffering from the disease, and its conveyance from infected to healthy persons requires con- ditions analogous to those which propagate Asiatic cholera, viz., from the use of water polluted by sewage. Of the many cases cited by the Commissioners in proof of this from all parts of England, I will give a few onl}'. MILLBANK PRISON. The number of convicts contined in this prison ranged from about 600 in the earlier years of occupation to upwards of 1,200. For many years the prison had a bad reputation for unhealthiness. Its inmates from the tirst suffered a very high rate of mortality. Of the four epidemics of cholera that visited England, the tirst three, viz., 1833, 1849 and 1853-4 were very fatal. In 1854 a new supply of water was introduced from an artesian or deep well in Trafalgar Square} and io the fourth 96 APPEISTDIX. epidomic. that of 18G(j, the convicts entirely escM[)P(l.

The ehangc! was carried into ell'ect in the midst of the cholera e[)idemic which so severely visited London in that year, and the prison was siiflering from cholera at the time. Six days after tJie chango the disease suddenl u ceased, and a marked improvement took place in the health of the prisoners. From the date of the introduction of the new water supply, up to April of the present year, (1872) a period of nearly nineteen years, there have heen oidy three deaths from typhoid, and one from diarrhu'a and dvsentery." It is thus shown conclusivelv that ft' X' «/ the disappeaiance of typhoid coincides exactly with the disuse of the Thames vvat( r, and as this change occurred whilst in all other respects the sanitary condition of the prison re- mained unaltered, there can be no doubt the two events were not coincidences oidy. Th^re must have been a casual relation between them. TERLING ESSEY. Here then was H severe outbreak of fever in 18G7. Of 900 inhabitants fully 300 were attacked in less than two months. No class of persons was exempt — the rich, the well fed and clad were attacked in common with the poor iind destitute. Dr. R. T.

" The conditions under which the waier lH?canie offensive were (1) where the wells wore low, the soiutioii of sewage being then most concentrated; and (2) when heavy rain by over flowing or soakairc seat a lot of cesspool stutf direct into the wells." SALISBURY. During the period 1842-.i2 Salisbury was supplied with water from wells, .S or 10 feet deep, in which the water stood 2 or 3 feet from the surface. These wells were generally situated close to cess-pits, the liquid contents of which soaked into the surrounding porous strata from which the wells were fed. The annual mortality from typhoid fever during a period of y years averaged 7^ per 10,000 inhabitants. In lf<56 a new supply of water was obtained from a deep well sunk into the chalk and a constant supply furnished at the rate of 40 gallons per head per day : and during the 8 years ending with \ii()\ the average annual mortality from typhoid fever was only 1,^ per 10,000 inhabitants. TOTTKXIIAM Had two sources of supply, one the common shallow wells of the neighborhood and the other from the water works of the local board of Health. It too bad au outbreak of fever 98 APPENDIX. in 1804 and 18(i5, and an inquiry made by Dr. Seaton on behalf of tl.e Medical Department of the Privy Council, elicited the fact that of 58 houses insnected tlio apMroxiniato number of cases in each was as follows : In 24 houses supplied from surface wolls 80 caseei. In 34 houses supplied from public water works 22 cases. And a further investigation showed that in most of the last named class, in which the fever had broken out, the inmates had been in the habit of golfing wat< r for drinking purposes from neighboring wells, rnconsciously imbibing fever and diarrhoea. SOUTHAMPTON. In his evidence before the Royal Commissioners on water supply, (18()0) Dr. K. A. Parkes. F. R. 8. professor of Medical Hygiene in Army Medical School at Xetley, says : I have got a ^'^ood deal of evidence together as to diseases which may i)e conununicated by wat<'r. *** I have made a list of disi^ases all of which are occasi;jiially conununicated by water, not solely communicated by water. For example, typh/id fever of which I have collected about 23 instances of local outbreaks of severe typhoid lever, and some six or eight more the particulars of which I have not got, are known to me arising from water iiii[)regnated with ty[)hoid sewage, or possibly with simple sewage. When I speak of typhoid sewage I mean sewage from piM'sons sutfering from typhoid fever.*** How did you ascertain that those outbreaks were due to water impregnated with typhoid sewage? On account of the cases immediatoly following that im- pregnation with typhoid sewage. I do not wish to deny that simple sewage may produce the same disease ; but that is a question still undecided.** Have you obtained any confirmatory results from that obtiervatiou? APPENDIX. 99 at im- ly that iit iv«i a There have heen altogether a considerable number of cases now placed on record Uy different writers of such an effect following the passing of typhoid sewage, or possibly of simple, into drinking water. We had a case in the neigh- borhood of S()ntham))ton, only this last year, in a young ladies' school whore a drain pipe passed within throe feet of the well ; at the point nearest the well the soft ground below the drain pipe had given way, and the pipe had sunk and the sewage passed into the water of the well. Immediately following that was an outbreak of typhoid fever, which affected something like 80 per cent, of the population, that is to say, 18 or 19 persons were aft'ected out of a population of 24 or 2fi ; there were many deaths, and many of them very severe cases. In that case it was impossible to prove whether or not it had been through typhoid sewage passing into the well ; but the impregnation of the water with sewage was certain and coincident at that time ; and that, coupled with several cases of the kind, seems to show that the outbreak of the fever was owing to the impregnation of the water with sewage. Numerous other instances could be cited from this invalu- able Report, showing the constant danger to which communi- ties are subjected whoso dietary water is drained from shallow wells sunk in a porous soil and surroimded with ash pits and privies ; but time will not permit. I cannot close, however, without placing before you the following remarks of the Royal Commissioners in relation to the propagation of disease through sewage pollution, page 183. , . ♦» The records of the poisoning of communities and families b}' the discharges from the stomachs and bowels of cholera and typhoid ])atients are obviously less strictly conclusive than corresponding instances in which men have succumbed after swallowing arsenic or strychnine, because in the former case the specific poison has not been chemically or micros- copically recognized, whilst in the latter the noxious agent 100 APPENDIX. c!in bo traced througliont its entire course, ami everywliore chemically identified. Nevertheless, after a carcfid consid- eration of all the f:ict8 accessihie to us, we are of opinion that the existence of specific poisons, capable of producing cholera and typhoid fever is attested by evidence so abund- ant and strong as to be practicably irresistible. The poisons of each of these diseases is contained in the discharges from the intestinal canals, and in tyi)hoid fever it appears to be [)resent in a yellow matter, which is secreted from an ulcero«i8 corruption in the bowels of the psitieut. Both this aiul the cholera poison may be disseminated, firstly by water, either as suspended matter in such an excessively fine static of division as to pass easily through ordinary sand or domestic filters: and secondly by air, either in the form of dust, or as the fine spray of liquid containing the poison- ous matter. Throuirh either of those two necessaries of life the zymotic germs of both diseases may thus be conveyed into the stomachs of large comnumities; but their effect will be determined, firstly by the power of the individual to resist the poison, and secondly by the degree of dilution of that poison. It is further exceedingly probable that a very attenuated poison will suffice to infest persons who are very susceptible of the disease, whilst on the other hand a very concentrated poison may fail to tell upon a person endowed with extraordinary powers of resistance ; such a power, for instance, as is conferred in the case of typhoid fever by a previous attack of the disease. The history of a large number of outbreaks of both diseases shows that where the poison was concentrated the disease manifested itself suddenly, that is to say, with a short incid)ation, and iu these cases a large p 'r eentage of individuals ex^josed to it were attacked. *** We have restrieied the above remarks to two zymotic diseases, but evidence is not wanting to show that other scourges, such as dysentery and diarrhaa are [)rol)ably pro- pagated by water which has received the excrements of 1 1 APPENDIX. 101 patioiits snffeniicr from those diseases. *♦• The means for prevei.tin^ir much of this death and torture are now well known iind c.ip.ihle of praftical ai)plioiilion. Their neglect really means the destruction of the people hy parasitic organisms that we have the means hut not the will to exterminate. t< 102 APPENDIX. APPENDIX C. SOFT WATER IN COOKING. Thfit the iiifliienee of hard and soft water in cooking may be shown more clearly, the foUowing brief extracts from evidence given at sundry times since 1850 — when the qnostion of city water supply in relation to health &C., was first submitted to scientific and searching inquiry by the (xen d Bonrd of Health, London ( Kngland) — to the present time, may interest such of your citizens as havi; not had an oppc.'rtunify of investigating this subject heretofore: Among the witnesses Cidlod by the General Board of Health, was the then justly celebrated cook (s'*'ce deceased) Mons. Soyer. This gentlemiin had published several works on cooking and had made many expiM'iments with a view to test the qualities of different waters for cooking pui'poses and in giving the results of his experience testified : That in boiling cabbage, greens, spinach and aspnragus, hard water gave them a yellow tinge — especially in French beans. H;ird water shrivels greens and peas, and will be more particularl}'^ noticed in French beans. The process in boiling is also longer. " The difference of time with dry vegetables was one fourth more," which means 2,5 per cent more fuel. He did not think it act(!d so much on potatoes, but still it had an influence on all sorts of vegetables; not so much on roots as on leaves generally. On salt beef hard water does not open the pores so freely as soft water. On fresh meat it likewise had a prejudicial APPENDIX. 103 1 efloct, but not cqusil to that on vefjetjiblos. It has tlie effect of making very white meat whiter than the soft water, upon all delicate thinjj^s it has however a more marked effect — for example in makinjr hi'cf toa, ehitken or beef broth, or upon lamb, and the more deli'-ate a substance is the greater is the influence of a hard water u[»()n it. A hard water as it were compresfies the pores, whilst a soft water dilates them, and the succulent matter which tlujy contain. It makes them more nutritious. Tlie evil of hard water is more visible in small quantities, such as broth or beef tea. BRKAD. He, Mr. Soyer, had not had practical experience in bread making, but there was not the least doubt that soft water was of the greatest importance as making the l)est bread. This is exemplilicd in Paris, where the water is hard and where that bread which is made in imitation of (ronness bread, though made with the same 1\om' and Ity the same bakers, never e(pials that made at the place itself where the water is .so/?. **'' At Glasgow the water is very soft and the scotch bakers from thence when they tirst come to London cannot understand why the bread does not rise so well as in Glasgow, even though they make use of the same yeast and flour; and (referring to London water) it is well known that the addition of a small quantity of bi-carbonate^of magnesia in the water renders bread lighter and whiter. TEA. " Hard water is injurious in deteriorating the flavour of tea. It also requires more tea to give an equal strength. Thcic can be no doubt that soft water is of very great importance, *** whilst with hard water three cups might be made. with 5()/i;,^'ye cups could be had from an equal quantity of tea of the same quality. The effect on Cottee is similar but not quite so powerful. (Report General Board of Health page 65-66.) ■M 104 APPENDIX. At the request of the Boarc] before whom this testimony \v;is g'iven Moii. Soyer uuidv a fiirlhei- series of experiments "Nvith a view to a eh)ser eompuiison of the rehitive vahies (jf Thames water and tiie Aitesian or deep well w.iter of Lon- don for tea maUinu", takinu' into aceonnt flavour as well as strength of extract. At the close ot the experiments, he re- ported to the Board as follows : In making tlu' experiments as time is of importance for the eli'cct, as well as economy, I thought pro[)er to take an account of it. — For culinary purposes, I am eoniident tiiat water which boils the quickest is the best ; and I conceived that this might be ascertained in respect to tea. I took samples of common teti in use by the [)opulation, green tea and tea of a third chiss, and prepared them with equal (juiintities of water. I took as a standard of soft water, dis- tilled water which 1 got from Apothecaries Hall. The ^vhole results were more striking then I had at lirst antici- pated. The soi'test or distilled water had an extraordinary power in obtaining a (piick extract. The result shewed perhaps too high a power, for it drew out the woody Havour. Next to it was the Artesian well water, which is one third less hard thiui the Thames water. 1 should indeed prefer that water to any other tried in these experiments ; although the distilled water draws out the aromatic proi)erty of the tea more th'Ui the Reform Club water, it does not, 1 think, produce so good an extract. Each water gave its own shade and had its own distinct extract. Finding the icsidts so extraordinary 1 solicited the assist- ance of two friends, the Messrs. Hooper, the most eaiiuent tea tasters in London, the results were the same. Mons. Soyer then gives in a tabulated form the time taken to boil the different waters experimented with (eight in all) and their rank in making tea. A [)int of each was boiled in a saucepan, with a gas lamp, under precisely the same ^ I APPENDIX. 105 ^ coivlitions, and while the softest re.'iched the boiling point in 5.J minutes, the hardest required ten minutes, and their rank as tea makers, stood as one Xofoai'. Kcs[)ecting the rehilivo power of the hardest and softest water, Mons. 8oyer gave it as his opinion, based on experieucc and observation, that while with hard water three lo) cups might be made from a gfveii (puintity of tea, with soft water ^Ve (5) could be obtained of equal qualiti/, and that tlic extra expenditiu'e caused to Ijoudoners by the use of Thanios (hardj water in making tea was nearly one-third greater than it would bo with soft water. Having been asked if ho considered the action of water in tea a fair test and representation in general in all the delicate processes of cookery, he replied : )f the link, hade ?sist- lincnt taken 1 all) loiled saiUQ ♦' Yes I do ; and I have proved it in the following way : I have taken the solution of !()" and compared it with the ' water from the well of the Reform Club. First, with vege- tables, that is carrots, turnips and onions, cut into small pieces of about one inch long and an eighth of an inch square, such as are used in Julienne soap, placed in two small pans with the same quantity of water and on the same gas stove. Those cooked in the Reform Club water were quickly done, and the flavor of the vegetables was in the water; whilst those cooked in the solution (of Iti" of hardness) nevei' became tender nor did the Jlavor go into the water. Secondly, with potatoes, I cut a peeled potato into two, and boiled them at the same time in the above waters. The diflerence was easily distinguishable. That which was boiled in the hard water being harder, but at the same time whiter. Thirdly, in extracting the juice or gravy from meat, the soft water does so quickly and well, but the hard water instead of opening the meat seems to draw it closer together and to solidify the gluten, and I believe the true flavor of the meat cannot be extracted by hard water. Aud at the same time U ■■■■ 106 APPENDIX. the mciit is not so tender as when boiled in soft water.*** I should in every way give the preference to noff water." In support of the statements of Mons. Soyer, Mr. Phillip Holland related certain accurate experiments that he had made with a view to discover the relative tea making qualities of liard and soft water. •* ♦ He had tea tnade with e(jual quantities of t!ie leaf and equal quantities of boiling water, and found that the tea made with the softened water " was stronner and better flavored, and the infusion had to be diluted with eighty per cent, ui Jiot water to bring it down to the strength of the hard water tea. Professor Clark also testified to certain experiments he had made in tea making wit!i water.s of 4°, (S", 1:J° and IG degrees of hardness. -Each experiuicuit with half an ounce of tea and one pint of water placed iu similar and separate teapots and the same conditions respecting time and heat. The strength was easily distinguis'ied by the colors. With water of 4 degrees of hardness the infusion was transparent with no sensible "muddiness; and at 1() degrees of hardness it was disgusting." P^xperiments were made likewise on second " drawings " of the same tea, and the water which was bad for a first infusion was still worse for a second ; and the conclusion come to by Professor Clark was that the only way to make an infusion of tea with waters of 4", 8", 12" and 1() degrees of hardness equally sirong was to increase materially in each case the quantity of tea. (Report G. B. H. page (59-70.) The testimony of Mons. Soyer in relation to the marked superiority of soft over hard water in all culinary operations has been confirmed since by many other observers, and endorsed by the Koyal Chemical Commission of 1851, the Royal Commissioners on Water Supply in 18(39, and by the Rivers Pollutiou Commissiouers iu 1874. APPENDIX. 107 SOAP. Eqiijilly stroiiir iiiul convincing evidence is on record respecting the superior economy of .vo/J! r/ hard water. This waste amounts to 25A oz. ofsonp in the usa of each 100 gallons of water of 1() degrees of hardness over and above that which would bo required with a water of 4 degrees of hardness; or with the piece of soap at 5 pence the pound, causes an extra cost of 8 pence on each 100 gallons, or six shillings and eight pence on each 1000 gallons ; being more than twenty times the coat of an economic vjater supply , as fur- nished in several towns, or as might be furnished to the metropolis, allowing 7^ per cent, on the capital required. Mr. Donaldson, the agricultuial surveyor, who has paid attention to this subject estimates the saving as follows : From several analyses and calcul.itions he says, as to the saving in soap by the use of soft water, and from inquiries I have made of numerous consumers of the quantity of soap used per individual, it appears that for evt ry lUO gallons of water used in washing two ounces of white curd soap is ■ 108 APPENDIX. required for ever t/ dvgveG of hardness. Thus water of 5" of hardness takes 10 ounces of soap, and one of 1.')" of hardness takes 30 ounces of soap. I find that 14 lbs. per Individual per aiuium is about the average consuniptiou of3'ello\v soap for washing and domestic use, and the price is about 5 pence per pound. Therefore, 100 individuals using water at 15 degrees of hardness, take 1400 Ibsof soa[) at 5 pence per i)ound, £29 3s. Id. stg ; and with water at 5 degrees of hardness, 4(i() lbs. £9 14s. 3d. stg. Ditlerence or saving, £19 98. Id. stg. In round numbers the saving of soap by i.sing water 5 degrees of hardness instead of lo degrees of hardness " is £20 stg., (say $100) per 100 individuals, extlusive of the tear and wear of clothes from washing in hard water, which will fully equal the saving in soap." In regard to the etfect of hard water on the wear of linen. Professor Clark observed : " With regard to the softness of water this quality is of importance, not merely for the saving of soap to household, for the agreeableness of washing at the toilet, for the agrec- aMeness and utility of bathing, which I account a most important practice for promofing the health of the inhabit- ants of a town, but also in respect to the wear and tear of linen due to hard water. Such wear and tear comes to be a very large item of expense to the inhabitants of a town. " The inhabitants of Lon(l(ui are not awaie, probably, so much as visitors from the coimtry are, of the amount of destruction to clothes in consequence of the hardness of the water and the use of soda in order to get rid of the hardness. I remember an occasion which I may mention, where the amount of we;ir and tear was brought out in a very con- spicuous maimer. Two young men, brothers, in Glasgow, were put into counting houses, one in London, and the other APPENDIX. 109 is of lold, gvev- inost liibit- rnv of be a y, 80 lilt of .f the iiess. e the ' coii- other in Ghisgow. They had each a siniUar assortment of shirts given to them. Sometime aftor when the brother in London came back on a visit to Glasgow, the ladv of the honse l)ointed ont, to the wonder of her female friends, the differ- ence there was in the wear of the shirts of the two brothers, that had been given at the same time; those that h:id under- gone tlie London washing were so much more worn than the others that had been washed in Ghisgow *** The hardness of the Glasgow water was about 4" and that of London al)out 12 degrees." At Bolton, when a change was made from water ot about 5', desjrees of hardness to water of about two dejGrrees of hardness only, the reduction of the expense of soap and ashes for washing at the Bolton Union ^Vorkhouse was foimd to be on the avenge of L3 weeks from £2 lOs. Id. slg. l)efore the change to £1 lis. lOd. .stg. per week with the pm-er water. *** A lady who recently crune to reside in London has found the ditference in quantities of soap and soda rc(iuircd to wash the clothes of the same household as follows : Cost in the country with rain w:iter, £0 Ss. 3 « stg. Cost in London, Chelsea water, 10 10:,^ Li addition to twice the time being required to [)erform thi^ work, (page 78-79.) And in reference to this same subject the Chemical Com- mission of IS b\ say, "The softer the water the better it is adapted for washing with soap; the earthy salts present causing a definite and calculable loss of soap which may l)e taken as amounting with every gallon of water used in washing to 10 grains of st)ap for each degree of hardness in the water. Thus, with one gallon of Thanies water at 14 degrees of hardness before boiling the loss of .soap would l)o 140 grains, and at 5 degrees of hardness 50 gr.iins ; or with 100 gallons of water the loss in the first case would be 32 ounces ami in the second lU ounces of soap. But such data 110 APPENDIX. arc not uloiio sufficient for caleuliitin«: the savinj; of soap elfected by tlie use of a soft water over a hard water ; for soap is used in washini^, not merely in quantity sufficient to soften the water, hnt in excess to act as a detergent. The problem is to determine how gre.it the portion of sosip h)st mi softeninc^ is, compared with the portion perceptibly used in washing in the softened water *** In the washing of the person the saving of soap l)y the use of soft water is most obvious. For l)aths «oft water is njost agreeable and bene- ficial. *** Its superior efficiency to hard water in washing floors and walls is calculated also to promote cleanliness in the dwellings of all classes *** while in the occasional domestic washing of linen the saving of soap makes a soft water highly desirable *** there is no doubt that a saving of about one-thlnl of the soap would be made by washing linen in water entirely soft compared with London water, of which one-third had been previously softened by boiling. The saving in labor would bo still more considerable." And Mr. J. F. Bateman, the justly cele])rated Engineer of the Loch Katrine Water "Works of Glasgow, C Scotland) gave the following evidence to the Royal Commissioners of 18(>1, in reference to the saving effected in Glasgow by the introduction of the soft water of Loch Katrine. " There is a great advantage and economy in using soft water, because it produces a lather with a less amount of soap ; you use less tea for making tea, and you use less cofl'ee for making coffee. *** lean give you the actual results in Glasgow from the introduction of the Loch Katrine water. *** The saving of soap was as follows : The manufacturers who used large quantities of soap and knew what their consumption was, found that they did the same work belter with three (3 > boxes, than they hud done, previonsl)/ ivitJi evjht (^8) boxes of soap: so that they saved five-eights of the soap previously used. I per- sonally inquired among some of the large printers and those APPENDIX. Ill who used water in Glasgow, nnd the savinir varied fVoin fully hnlf to tive-eights, but the most «reneral computation was oiie-l;alf. *** Then fnun ealculatioii.s made l"y very careful lioiisekecpers, they crilculated that the saving l)y the use of Loch Katrine water, to say nothing of the wear and tear of clothes in washing, was quite eijual to the rate which thoy paid for water, and on the north side of the river it was then / 3(),00() stg. a year ; so ih it the saving to the city of Glasgow *** amounted to tiro shiUiwjs per Jiead per annum *** I may mention (Mr. Bateui:ui continues to say) that in my own house in the country I introduced about three years ago verv soft water, equal to Loch Katrine water, in place of hard water, which I had before, and the saviny amounts to about four io Jive s/tillini/s per head on the household soap used in my establishment for house purposes an I washing. *** Those who know the delight of washing in Manchester or in Glasgow^ in their water as compared with the London water, will understand the ditJcrence. *** All you have to do with these waters is to touch the soap and you have soap enough to wash yourself i)erfectly. Li many other ways, in the health of the people and in the tear and wear of clothes, they are saving. It is ditlicult to put the matter in figures, but if the saving in Glasgow is some forf>/ thousand pounds (stg.) a year, uiM)n a pi>pulation of 400,000, they would save in a population of 5,000,000 (London) three hundred thoU' sand pounds (stg. i A year, sii\ipos\ng the difference in the hardness to be the same. The change in Glasgow was from water of l> degrees of hardness to 1 'j degrees." These extracts and opinions might be extended to a great length, but it is unnecess;iry. In the course of the inquiry, from the evidence in which I have j.ist been quoting (Royal Commissioners on Water .Supply, 1861,) the ablest engi- neers, physicians and chemists of Great Britain were examined, and all, without exception, gave a general support to the great ecouomic value of soft water over hard for 112 APPENDIX. cookinj^ and washing, thongli there was a considerable divergence of opinion concerning the nctniil per centage of saving in Hf)ap and other articles. And in snnnning np, tlie Connnis8ioners .say : ♦' There in no doitbt that the evidence is conducive and cogent as to the (fveat advantage of soft water over hard for ivashing, and with some few iniportaid excep- tions, for manufactvrinii jiurjjoses. And the Rivers Poihition Coninii.ssioner.s in tlicir fninninry of conclusions ati to the superiority of soft over hard water for washing, cooking, and nianufai luring opeiations, say, (1) "The washing of linen can only he performed with soft water. If the availal)le water he hard it must he artifici- ally softened — an operation which on the domestic scale must he performed at a great expense hy the aid either of fuel, sod.i or soap. In personal al)lution, also, the use of soft water is much more pleasant and etticicnt. It is also economical; but by the general use of a very small quantity of water the waste of softening material is much less than in the laundry." (2) " In cooking, the extraction of the soluble parts of such materials as are submitted to boilini^: or to digestion at high temperature, is more completely and economically effected by soft than by hard water. (3) "In manufV.'turing operations involving the use of water, soft water is almost without exception preferable to hard. Dangerous incrustatinns in steam boilers are pre- vented by the use of soft water." Report, page 427. APPENDIX. 113 APPENDIX D. ANALYSES OF W ATE II, BY PIIOF. HAYES.
