 To nu; lldNOKMii): John Rosk, ("onunisssoner of I'liblic Works. 
 
 Sir, —I have llic liuiuir to submit iicrewith my Rc|)ort upon llic Ottawa navigation, in 
 accordance with instructions received troni tiie Department of I'ublic Works, and hereunto 
 a|)i)ended. 
 
 'I'he (iiieslions up')-: whi( ii intorinatiiin is souj;Kt, and to answer which tlie Survey 
 has l)een carried on tiurinu the past year, are as follows ; - 
 
 I, To dL-lermine the practicability ot a navij^ation for vessels of the larger class, be- 
 tween Montreal and I/ike Huron by way ot the River Ottawa, and its tributary the Malta- 
 wan, l.ukc N'ipissmguc, and the I'Vench River. 
 
 II To ascertain what scale is i)est suited to the n.uure o! the refute. 
 
 III. i'o give a reliable estimate ot the cost ot the improvement. 
 
 In the liist jjlace, I have to reju^rt that the di>tance between .Montreal and the mouth 
 (if l''rencli Rivlt (jn Lake Huron (according to the plans furnisheti me by the Depart- 
 ment,; is. following the line of navig.ilion adopted. 4,^0.76 miles. 
 
 That ot this distance ^.ii.^ii miles are already a good natural navigation, and recjuire 
 no improvcmcnl, and that It is |)ertc(tly practicable so to improve the remaining /S.y5 
 mile-:, as to ciisivert the whole chain of waters into a t'lrst class navigation for steam 
 vessels, and to reduce the length of canalling to 29. 52 miles, or, exclusive of the Lachine 
 (Janal, to J0..S2 miles. 
 
 Secondly -The scale of navigation attainable, and which I would recommend as best 
 suited to the capabilities of this route, is calculated for vessels of one thousand tons burden, 
 and has Locks 250 feet long by 45 feet wide, by twelve depth, on the mitre sills. 
 
 Finally —.\ careful estimate, resulting from a close instrumental survey of all ob- 
 structed points, the details of which will be found hereafter, enables me to state that the 
 cost of this improvement, exclusive of interest, legal expenses and land damages none of 
 which 1 have any means of ascertaining, will not exceed the sum of $12,057,680, dis- 
 tiibuted as follows: —

 I. -PHYSICAL (:H.\R.\CTERI.S1K:s ok the O'l'l'.WVA. 
 
 Before taking up in detail the method of improvement jiroposed lor this chain of 
 waters, I shall sketch brieHy the physical geoi^raphy of the Ottawa X'alley, and some of 
 its prominent geoloj^ical features. Nor is this foreign to an l',ngineering report, lor, in 
 order to clearly understand the matter of the changes pro[)osed, we must first get a cor- 
 rect idea of things as they are. 
 
 Rivers have been well defined as the channels by which the water, originally evapor- 
 ated from the sea, and falling upon the land, is returned to the sea again, and the volume 
 of water discharged is the excess of precipitation over evaporation throughout thefvalley of 
 any river, varying directly with the area of drainage, the rain-producing character of the 
 atmosphere, and the nature of the soil. 
 
 Their i)osition is determined by the laws of gravity, and they always follow, from the 
 interior portions of continents to the sea, the line of quickest descent, — that is, the line 
 of lowest level, whether resulting from upheaval, denudation, or the combined effects of 
 both. 
 
:\ 
 
 The <haracteristi(:s of rivvr^ arc much modinnd by the nature of the j^cological furin- 
 atioiis lhroui;h which they pass, and their ditfercni puwcrs ot rL->istan( e to the trans|)(trt- 
 inn and eroding ciTcrt ui the waters. 
 
 In a country hased upon sedimentary rock-., \vhi( h are not hard enou^;h to resist 
 the force of the < urrent, and generally do not appear aDove the surface at ali, the form- 
 ation of river channels is a [jrocess similar to that which we see when a shower falls upor» 
 a newly cultivated fielcl. The water follows the lint of (juickest djscent, hut meeting 
 material of different degrees of hardness, it meanders about from right to left and as- 
 sumes a sinuous course : i:s constant ten(ien(y being to elongate its channel and conse- 
 ciuently dinnnish its slope 'IMie^e windings arc so great in some rivers as to double their 
 length, as HI the case of tile Mississippi, between the Ohio and tin (lulf of Mexico. 
 When the length of the channel has been so much increased as to diminish the slope, 
 and the C(jnse(|uenl veloi ity of the cuireiU to sik h a rale that it will eat inti> the shores 
 no longer, the regime is said to be established. 
 
 Mut in a formaiion composed of the harder ( rystalline rocks whi( h obtrude them- 
 selves above the surface, the w;Uers have not the same powrr to form f(jr themselves 
 channels : and the characteristics of the rivers of such a < nunlry are very liifferent from 
 those previously described. 
 
 'I'he irregular depressions and clefts in the siirfa( e be( onie f'llled with water, and 
 form Lakes, whose overflow tumbles in cascades and rapids, over the rocky barriers 
 which it cannct destn<y, until it finds its way into other l.ake>, lying at a lower level and 
 from these to others, until at last it is receiveil in some sue h arm of the sea as the (lulf 
 of .St. Lawrence, or Hudson's I '.ay. 
 
 .\ glance at the map of our cf)ntinent will show at once the distinctive peculiarities 
 of the tw(j systems ; norlh of the .St. i .awrent c, in the region of crystalline rocks, the 
 country is dotted with Lakes and the connectinj^ rivers are generally short. In what 
 may be termed the Mississip|)i system, there are but few Lakes, and the rivers are long, 
 and marked by a jief iiliar sinuosity ot course. 
 
 Owing to the absence of the harder rocks, there are btit lew ca.scade> and rapids. 
 The currents are strong, but all the tributaries of the .Mississippi have at some seasons of 
 the year a natural navigation for boats of light draft of water. 
 
 (Jn what we may call the northern river system, the navigali(jn consists of stretches 
 of deej) and iitill water, interrupted by ia|)ids and tails : around which the light canoes of 
 the voyageurs are portaged by hand. 
 
 The ot)stacles to the imitrovement of these two river systems are of an entirely op- 
 posite nature. The |)roblem in the one case is to regulate the natural flow, so as to re- 
 tain sufficient depth for navigation in summer, and to defend the surrounding country 
 from the disastrous inundations caused by Spring floods, which often rise to a height of 
 fifty or sixty feet above the Summer level, and would jirobably sweep away any artificial 
 works intended for the improvement of navigation. .\s the country becomes more widely 
 jettled, and a larger area of timbered land is c Icared away, the evil increases ; for swam|)s 
 diminish evaporation, and actas natural reservoirs to moderate the violence of torrents. 
 
 Our river system, fortunately for us, is furnished with a series of reservoirs, which 
 cannot be destroyed, in the Lakes themselves. These Lakes receive the waters from the 
 melting of the snows in the spring, and hold them steered up against the summer heats. 
 Hence the beautiful uniformity of the flow of our rivers. The St. Lawrence, unless 
 danmied by ice, seldom rises over four or five feet : and the average rise of the Ottawa, 
 where free ffoin obstructions, is about twelve. There are few more l)eautiful illustrations 
 of that beneticient design, which adapts the physir al structure of the earth to the wants of 
 its inhabitants than this ; for, from the unretentive nature of the soil, the rain would es- 
 cape nearly as fast as it fell ; and the northern rivers would be torrents at one time, and 
 nearly dry for the rest of the year, were it not for the.se natural reservoirs in which the 
 surplus waters have been stored uj) among the hills. 
 
 To improve the navigation of such a river system is a comi)aratively simple matter, 
 for the greater part is already done to our hand, and we have only to devise some means 
 ot getting from one Lake to another, and our task is accomplished. 
 
 This brief sketch of the more prominent peculiarities of the northern river system 
 of this Continent, will enable us readily to comprehend the physical characteristics of 
 the Ottawa, the largest of the tributaries of the St. Lawrence.

 riu two ttreat L;".('!oi;i(al divisions of its roi ks are I.aiirentian and Silurian. 
 
 Thi 
 
 I.aurentian rocks are supposed hy j^coloi^ists to have heen the surfaie ot the then existing 
 continent, and the lloor o\ the sea upon which tlie sedimentaiy Silurian ro<:ks were 
 de|)osited. 
 
 The outlines ot the shores of this aiv lenl continent followed the Nurih hank of the 
 St. i.awrt.nce, and tiu ive ran up the ( >;iaw.i, skirting its north shore at varying distances. 
 The |)resent Ottawa \ .iliey. as far up as Deep Kiver, sei.ins to h.ive been a hay or inlet 
 of the Siluri.ui Sea ; hiuiudeil on the North ,ind \\ est hy the mam ( ontiiient, and on the 
 South hy a iieninsula wl ich runs into Northern N\\v \( rk, and forms that wild section 
 of country ol which the .\<iirondack .Mountains aiethe I'.astern boundary. 1 he River St. 
 Lawrence has br 'ken throU);h the istluniis which connei ted tliis iieninsula with the main 
 land, in a ^real number of (hannels. rorinin^ the celei")rated ^roiip ol the I'housand Islands. 
 
 I'he surfa<'e ol this 1 .aureiUian Innnaiion i-. eMremel)' ruuui d. and the nx ks are 
 contorted in a manner that --iiow's tlie action of some e.xtraordinary forre. There is little 
 levelland, and the hollows between the roiky hills i.re niUd with innumerable lakes, 
 whose water is i lear and deep. 'The whule region shews the wearing I'lTect of water, and 
 has evidently been mu< h inllueiiced by ^l.ici.il action, as m.iy be seen Ikjiii the grooved 
 appearance of the rf)cks and the hiils, and the huge deposits of boulders that cjioke up 
 jjortions ot the river beds. The rorks consist chiefly of micaceou> and hornblendic 
 gneiss, mica slates, and veins of crystalline limestone. 
 
 The Silurian roi ks, on the other hand, are sandstones .uid limestones ; lying in reg- 
 ular strata, ll.it and undisturbed as when deposited on the lloor of the ocean. 
 
 I'he truth of the observation ot Hugh .Miller that the jihysiognomy of the landscape 
 depends upon its geology, is nowhere more evident than upon the L'|i|)erand Lower <> tlawa. 
 
 Trom .Montreal to I )cep River the ( )itaw.i runs in .i Siluri.ui valley : .ilthough at some 
 points, as the " Rocher T'endii" and the (."hat--, the crystallini' rocks shew themselves in 
 the channel of the river. 'The general features of the landsfajie arc those of a level 
 country, like that or all limestone formations. Uocky barriers have jienned back the 
 waters into long lakes, like the I )es (Jhenes anil C^liats. whose shores are low and flat, and 
 generally cultivated to the water's edge with fertile farms. 'The timber is hardwood, 
 principally beech, maple, ash and elm. The width of these sheets of water is from half a 
 mile up to two miles. Along the Northern shore at varying distances, runs the unbroken 
 outline of the Laurenlian hills ; which, as has been staled, were probably once clilTs 
 against which beat the waves of a Silurian sea. 
 
 .\bove I >eep River the character of the landscape changes. We are now entering 
 upon the oldest part of our continent, whose rugged masses and contorted outlines speak 
 ol the convulsions of former ages. The hills that had admitted a strij) of level 
 country between their bases and the river now crowd close upon its edge, and rise pre- 
 ciijitous. in some places to the height of seven or eight hundred feet. Tht groves ot 
 hardwood give place to those vast forests of pine of which the wealth ot" the Ottawa 
 chiefly consists, and the clearings are few and unimportant 
 
 An we advance, the scenery becomes more wild and rugged, and the pictures(]ue 
 beauty of the cliflTs and cascades of the Mattawan, and of the lonely isles of Krench river, 
 is unrivelled in any part of the continent. 
 
 Lake Nipissing is of irregular shape, from forty to fifty miles lon{{ and twelve to 
 eighteen wide, and receives the water of seven rivers : two of them, the Sturgeon and 
 Nauwanitigone, of considerable size. The south and west shores are bold, and the depth 
 of water is great, 'i'he north and east shores are low and flat, and the water shoals 
 
gradually. 'I'he westtrn end ol the Lake is lillcd with islands, and the shores are cut up 
 with inlets ending in marshes.

 i'"roiu the prec eding skeic h. the following conclusions mav be cieduc:ed : — 
 
 That there are two great natural divisions cif the Ottawa country ; on one of which 
 the banks of the river are low, and the rocks generally soft ; while on tlie other the shores 
 are precipitous, and the roc ks hard. 
 
 I'hat th '*"awi is a river of very even flow, and n )t subjci't to sudden rise or de- 
 structive fresh<Ub. 
 
 That thj e.xtcnt ot obstructed water requiring iini)rovement is but a small proportion 
 of till- whole, and that the greater part is a chain of inland lakes, affording a good natural 
 navigation. 
 
 How to correct these unobstructed (larts is the ipiestion now to be considered. 
 
 When a river is obstructed t)y ("alls anil rapids, there are several methods of making 
 it navigable. 
 
 I. We may c:ut L'anal< aronnci the rapids, an 1 lork up and down through them, 
 keeping away tro n the river, and letting it entirely alone. 
 
 II. We may throw dams across the channel of the river and convert tlie rapids into 
 a series of still lakes, and lock directly from one into another. 
 
 III. Wc may combine these metho Is by c.inalling around r.ipids, and using low 
 dams to give tlie recpiired depth, and to drown out currents between canals. 
 
 Sometimes one of these methods is most a|)plicable to a jiartic ular locality, and 
 sometimes another ; and the judgment of the engineer is shown by his choosing that 
 which best suits the circumstances o( the case. 
 
 On the lower Ottawa, where the Lakes are long and deep, and the shores lov and 
 highly cultivated, it would be unwise to attempt to alter the existing levels, for we should 
 drown a large e.xtent c»t country, thereby destroying arable land, and probably rendering 
 what was le(t unhealthy. Whatever plan is iirojKjsed will carefully avoid disturbing the 
 long levels. 
 
 Hut fortunately for the project, on the greater i)art o( the river, where the water is 
 recjuiredto be raised, the shores are i).)ld, and the desired lift would overflow but little 
 land. Mere we have only to raise the natural dams or rcjefs of rocks to the desired 
 height, by ariiticia! structures, thus restoring a condition of things which possibly existed 
 before the ceaseless rush of waters, or glacial action had worn the rock dams down to 
 their present state. 
 
 Wherever canalling is resorted to, the canal will follow the shore, and be con- 
 structed by embankments rather than in excavation, on account of the great saving of 
 expense over thorough cuts in solid rock, t)\ the large dimensions necess.iry for the navi- 
 gation. 
 
 The whole key to the system of improvement proposed for the Ottawa is comprised 
 in two propositions. 
 
 i. Follow the natural bed of the river, and avc)id cutting into the rocky shores. 
 
 II. (lam the depth rec]uired for n- .igation by raising the scjrface of the water rather 
 than by submarine rock excavation. 
 
 We may lay it down as a general principle that, although on the lower part of the river 
 where the shores are flat and lie upon sedimentary rocks, we could dispense with the use of 
 
 *NorK. — When the lip of the strata is in the direction of the ciirrpni, the w.iter has only an erosive 
 force ; l)Ul where it is against the ciirreni, the strat.\ are iiniiermineii, (all frcnn their own weight, ami are

 dams ; yet as soon as we enter upon lliose portions wliere the river lias cut its lied through 
 crystalline rocks, (which is more than lull the whole disiaixc l'ron\ Montreal to Lake 
 Huron), the only mode by which a navigation can be made at all is by raising the water 
 by dams. 
 
 'I'here is not now depth enough of water ; the cnrrenis are too strong to In: over- 
 come ; and as the shores rise almost perpendicular from the water's edge, there is no 
 room to construct laiials ; moreover, even if there were room, the length of arliliciil 
 canal required would be so great as to condemn the prtiject ; and there can lie no doul)t 
 of the sui)eriority of a still deep, lake from two to three hundred yards wide, tor purposes 
 iif navigation, over a canal ol litly yards in width. 
 
 I'ortunately every existmg condition tavors this moiie of construction. 
 
 I'he bed ot the river consists of hard crystalline rocks, worn smooth and gcnerall\- 
 free from boulders ; and the shores o( the same material rise abruptly on either side, 
 diminishing the length of the dam reipiired. 
 
 Points can be olitained where the water is shallow, and where there are rockv islaniis 
 which will act as natural buttresses I'or the structure. I'nder these cucumstances there 
 is no more danger ot a projierly constructed llat dam i)eiiig disturoed than one of tlij 
 islands themselves. 
 
 .\s has been previously said, the O'tawa is not a river subject to sudden rise or 
 extraortlin. Hoods. It never averages over three inches in twenty four hours for any 
 number of .. .ys in succession : its ct)mmon rise is one in<h per day. Its rise to its high 
 water mark, stand, and subsequent tall, occur every year at nearly the same dates, with the 
 utmost regularity. (See appendix tor Table •'(".") 
 
 There is very little shove of ice in the Ottawa, where dams would i)e reijuired. 
 
 .So ample is the volume of water, even in the driest time, that notwithstanding 
 leakage and the effect of wind blowing down stream, the dai is would be always submerged, 
 with from one to two teet ot water running over their crests. 
 
 .\ very important effect of dams upon the Ottawa will i)e to diminish the variation 
 between high and low water. This is always proved to be the case wherever they are 
 built, for there is a greater area to be filled up by the Hood waters before they can rise ; 
 and th.e dis( harge over the top of a dam is so tree that the water can m.-ver rise above it 
 to the same extent that it lioes m a river channel obstructed by islands and sunken 
 rocks. 
 
 in designing a system of dams for the Ottawa improvement, we should have the 
 actual volume of water discharged both at the lowest and highest recorded stages. This 
 would reipiire a series of gauges in different i)aris ot the river, taken for a term of years, 
 until the greatest and least (low was as<'ertained Irom actual measurement. 
 
 .•\s the time of this survey has been limileil to one season, I < annot i)retend to have 
 attained such aecurac'y ; nor, merel\' for the juiriiose of an estimate of cost, is it necessary. 
 It is only requisite, for that put pose, tliat what is assumed as the greatest and least volume 
 should cover the extreme limits of variation 
 
 The results of several guages give, for the summer volume of discharge, at Portage 
 du Kort, ^^1,000 cubic feet per second, and that of high water, 127,000 cubic feet per 
 second. I'Vcmi anything on record, it does not api)ear probable that the least discharge 
 ever falls below 25,000 cubic feet per second, or the greatest over 130,000 These 
 ([uanlities, I'lerefore, have been assumed as a maxim and miminiun (see .Appendix, 
 Table "D") 
 
 Where the dams themselves act as waste weirs, it has been thought preferable to 
 raise the masonry of tbe upper or guard lock, and allow the water to rise as high as it 
 would upon the crests of the dams, rather than to attempt to control it by guard gates in 
 the body of the dams, as this would be introducing a perishable material, and mode of 
 construction, into the body of the work. 
 
 'l"he height at which the water will stand upon the crests of the dams for different 
 volumes of discharge, has been calculated by the formula tor weirs, originally due to the 
 investigations of Du Buat. 
 
 Let Q be the number of cubic feet per second, and L the length of the overfall o' 
 dam be known and we can obtain : 
 
II. - Ti!0 height at which the water will stand above the crest of the dam from the 
 simple e(iiiation H-( i) )~i 
 
 I'.y this formuia the table of dams (see ajjpendix I)) was calculated, and the height 
 of the co|-ing of guard locks established. 
 
 It will be seen that these dams will have from 1.31 to 3.51 of water running over 
 them at low water. Vet for pur|)oses of estimating, their crests have been assumed to be 
 as iiigh as the level of water above them, which gives excess of material. 
 
 One other ])oint demands notice. We know that by dams we can drown out cur- 
 rents, in these Lakes themselves, strong enougli tt) affect navigation. 
 
 'ri\e velocity of any (iirrcnt depends directly upon the area of llowage. When that 
 is large in projjortion to the volume, the velocity is slow ; and as the area diminishes, 
 the velocity increases, in ouler that eipial voIuiiils may pass in e(|ual times. Mow great 
 this velocity will heat an> |)oint is strictly a matter of calculation, founded on well known 
 hydraulic laws. Without here giving details, it is sufficient to state in general terms that 
 the present area of llowage will be so much enlarged by the depth of water thrown on by 
 dams, that no greater velocity of current need be apprehended than three miles an hour, 
 at any |)oint, even during the six or sever weeks ot higli water ; and during the rest of the 
 season the currents will be entirely imperceptible."*

 In accordance with the instructions of the I )epartment, the (piality of the works is 
 proposed to be not inferior to the standard of the St. Lawrence (Janais ; and every thing 
 has been designed as substantial as jjossible. It is believed that there will be nothing 
 perishatile but the lock gates on the whole line. 
 
 Dams, where carried above water, will be of rough but strong rulible masonry laid 
 in cement ; wherever the water runs constantly over them they will be tlat timber dams 
 composed of solid timber laid up crib-fashion, without fiaming, fastened with '4 inch 
 sipiare l)olts, 20 inches long, at each crossing rock bolts ^^ inch round ; to be filled with 
 loose stone, covered with 4 inch ])lank, well spiked, and staunched with gravel, similar to 
 those usually constructed by the Department in connection with timber slides. 
 
 In most places the water can be diverted by a rough coffer dam, and the permanent 
 structure commenced directly ujMin the flat rock. 'This operation is much facilitated by 
 the numerous channels into which the river is divided, at the pcints selected, by large 
 and small islands. The dams can be run from one island to another, and passages left 
 for the discharge of the waters, which can be afterwards closed. 
 
 When the water is deep, recourse must be had to the system of sinking cribs. The 
 dam should, where possible, be laid out upon segments of circles arching up stream ; a'

 and it is b.;lieved that a I jck ige need not take over tea miiuues, the averigc time on 
 those locks of the Si. Lawrence (Janais, where the latest improvements in machinery and 
 gites are used. 
 
 In arranging the lo(ka.;e it h.as not been fjunci necessary to place in ire than two 
 locks ill ci.in'ain iiion, except at the Talon (!aure, where tiiree h.ive been combined, the 
 contour of the ground prohibiting any other arrangement. 
 
 The cost of the execuli<jn of this work will depend, more than anything else, upon 
 the character of the rock, its hardness in excavation, and its suit.ibleness for purposes of 
 construction, .'Vs has been before stated, the two great divisions of the Ottawa rocks are 
 Laurentian and Silurian. The former are very hard, dilHicult to work, and too brittle for 
 the face stone of locks ; while, on the other hand, the Silurian lime and sandstones are 
 easily excavated, and, from the upi)er beds of the limestone known as the Trenton 
 group, we can procure a bu'ldinR material excellent in every respect, both as regards ease 
 of workmanship, strength and durability. From some of the .\rgilla''euus beds a good 
 hydraulic cement can be obtained, such as is now made at Hull, opposite Ottawa City. 
 
 We know, then, that from Montreal to Deep River, building stone lies all around us, 
 but from th It p »int to Like Huron, it was much to be feared that ihe stone of the 
 country, although good enough for b.ickmg lock walls, filling lock dams, and rough 
 masonry in general, could not be dep.aided on for face work. Luckily, however, this is 
 not true of the whole of that extent of country. .\ bed of yellow weathering, fossili- 
 ferous limestone, on the North-east shore of the river, a little above the Deux Rivieres 
 Rapids, will afford good stone for the structures in that district and on the lower Mat- 
 tawan. 
 
 At Talon Chute there is a vast mass of crystalline limestone, described in the Geo- 
 logical Rei)ort, which is a fine grained and tolerably tough stone, and appears to be good 
 enough for face work. Tne locks at that jjoinl have been estimated to be built of it. 
 
 'The face work of the remiinder of the locks upon the lower NLittawan is designed 
 to be built from a (juarry of gray granite (probably an intrusive dyke) on the north side, 
 about half a mile from the river, below Pares-^eux Chute. 
 
 For the structures on French River, the face stone must come from the beds of 
 Niagara limestone, on the Manitoiilin Islands of Lake Huron. This will much increase 
 the cost of that portion of the work, and render its construction necessarily gradual. 
 
 IV. SCALE OF NAVIGATION. 
 
 The first point to consider is, whether we are designing a local or a through Naviga- 
 tion. This would be decided by the general depth of the chain of waters, the difficulties 
 
9 
 
 It::, 
 
 of overcoming; the summit, the siipp'y of water, and other points, more or less closely 
 connected with the pn;ccdin{;. 
 
 'I">) iliese my intention was first directed, and after careful personal examinations of 
 the wliole route, aidL-ii by the i;rai)liic report of Mr. Siianly and the result of such Surveys 
 as were at tlie time made, I was able dL'finituly t') decide, tiiat, whatever scale was fixed 
 on sliould 1)0 wuh the view of cdrnpleting, at some future day, tlie through line of Navi- 
 gation. 
 
 It must i)e home in mind that this is exclusively a steam navigation ; sails, although 
 useful aiiNili.uies, would nuver alone enable vessels to pass through this route, with any 
 saving (if lime over that by liie W'elland (";m;il* 
 
 .'iic next jioiiu is, whether we shall build locks fitted for large vessels ; or whether, 
 pre^trving tlie dimensions suited to an inland and Local Navigation, we siiall cause a 
 tr.inslii]iment to lake place at the mouth of French River, which is about half way be 
 tween (^liiiago and Montreal by this route. 
 
 This ipiestioM is determined by the length of Canal (or what is cipiivalent in delay 
 to an artificial cm ) on the route where a large proportion of the distance is canal. I 
 sho'ild then te^vimmend tninshipment ; for I believe tiie unwieldness of large vessels, on 
 accLUnt of their top b.iinper being arted on by the wintl, — the risk of damage to the ves- 
 sels an(i to the wotks in the nuiow channel ot the (!anal. and the delay arising from 
 tlusi' c ;iii-c--., wouKi more tiian i)alance the cost and trouiilc of transhi|)menl into steam 
 barges better siiiied lor l.'anal navigation.! 
 
 .\s soon as I iiad ascertained that the length of Canal on the whole roiite, including 
 Lachine, would not exceed 21/32 miles and that the remaining 401 "44 miles could be 
 made a naviL;aiion allowing of as rapid a transit as the great Lakes themselves ; and in- 
 deed more so, so fir as freedom from liead winds and storms is concerned ; I was then 
 prep.Ui d to recomuieiui the larger scale, and an unbroken line of Navigation. 
 
 it only remains to deride how large. When crops are good, and full freights offer, 
 it is an admitted axiom, that, the larger the V'^>;sels the cheaper the cost of transport. It 
 is a fortunate pecularity of this route that vessels can always depend upon making up 
 full freights of sawed lumber from the inexhaustable pine forests of the Ottawa, manu- 
 factured at every dam on the river. 
 
 It requires then, I think, no argument to prove that we cannot err in providing to 
 let down to Montreal the largest class of Propellers, now confined to the Upper Lakes by 
 the limited size of the W'elland Canal. 
 
 From these data, and after consultation with various jiersons experienced in the Lake 
 Trade, I hive fixed iijjon the dimensions given, as follows: — 
 
 The length proposed by Mr. Shanly, and suggested in the instructions of the De- 
 partment, 250 (eet, is long enough for vessels of the desired touage. It does not, iiow- 
 ever, seem desir.ible to exceed the breadth of the St. Lawrence Canals. 45 feet ; because 
 this is in itself wide enough ; and because it makes the enlargement of the Lachine Canal 
 attainable, without pulling down the present lock walls. 
 
 The depth has i)een fixed at 12 feet, which is absolutely necessary if we wish to ad- 
 mit vessels ot over six hundred tons, as will be seen from the table of large Propellers 
 (given in Appendix K) for which I am indebted to the kindness of Capt. I). B Dobbins, 
 Secretary of the ])oaid of Lake Underwriters, lUifTalo, N. Y.

 " It is as :i Steam N.ivigation, aivl more especially for that denomination of Steamers known as "Pro- 
 pellers," that I believe the Dtlawa and i'rench River route is destiiH<l to hold a first place as a Channel 
 of Trade. For vessels of that description the character of the waters, and of the region on either side of 
 them, is peculiarly titled. Land locked for the t;reater portion of the way, the route will not in that re- 
 spect be as advantageous for Sailing Craft as that by the great Lakes, but ihe inexhaustiiile supplies of 
 wood at all points along it, and the facilities for taking iheir fuel on board at freipient intervals, will for- 
 ever rentier the cost of working Steam Vessels lower on this than on any equal lenijth of Navigation on the 
 continent. Here, too, the Tropeller can keep the even tenor of its way heedless of the storms which, 
 sweeping .icross the Lakes in the Autumn of each year, cause such immense destruction of life and 
 property."

 Although, through the heavy cuttings, as where the distance is short, I have fol- 
 lowed the width recommended by the Department, I oo feet on the bottom, I have not 
 hesitated to increase the prism of the Canal generally to 146 feet on bottom ; as I believe 
 that is not more than is required for vessels to pass with speed and safety. The depth 
 has been fixed at one foot more than the locks — say 13 feet ; and in Lakes and Rivers 
 will be 15 feet, and generally average 20 feet. 
 
 V.-SPECIAL DESCRIPTIOiN. 
 
 Commencing at the City of Montreal, we have the Lachine Canal common to both 
 the St. Lawrence and Ottawa routes. It is 8.5 miles long ; has five locks, 200 ft. x 45 x 9, 
 with a total lockage of 43. 715 feet. The prism of the Canal is 80 feet on the bottom, 120 
 at water surface, and averages 10 feet deep. This would have to be deepened, and the 
 locks lengthened to admit vessels of the same tonnage as could pass the proposied Ottawa 
 Canals. 
 
 As neither the time nor means at my disposal have enabled me to make a survey of 
 this, I have not included it in my estimate. The enlargemept involves no serious obsta- 
 cles, and will, probablv, be made whether the Ottawa Navigation is opened or not, 
 
 A map of Lake St. Louis, made tor the Commissioners of the St. Lawrence improve- 
 ment, in 1842, by A. LaRue, P. L. S., shows a channel depth, somewhat circuitous, of not 
 less than 15 feet from Lachine to Isle Perrot. For reasons given above. I have not made 
 any survey here, but am informed by pilots that there are 15 feet, and over, along the 
 North Shore of Isle Perrot, up to the foot of the present St. Annes Lock. I have my- 
 self, taken soundings for half a mile below the lock, and over that distance can corrobor- 
 ate the truth of their statement ; but it is much to be desired that there should be a new 
 survey with soundings carefully made from St. Annes Lock to Lachine.

 I jiropose to enlarge the ])resent lock to the requisite dimensions, as it occupies the 
 best point that can be selected. In order to do this it will be necessary to put in a coffer 
 dam and pump it dry, take down the east wall, and get the pit sunk to the proper depth, 
 as early in the spring as the weather will admit of laying stone. Then by working night 
 and pay. it would be possible to complete the new lock without dehtving the opening of 
 the navigation for more than three or four weeks. 
 
 I will be necessary to build a guard pier 1000 feet long helow the lock, on the side 
 next the rapid, to cut off the current, which, at high water, is strong enough to incommode 
 vessels very much. This will be an ordinary crib-pier filled with stone. 
 
 Above the lock, the river bed is Potsdam Sandstone, in strata of from five to eigh- 
 teen inches thick, somewhat tilted upon one another, and covered with boulders from 
 the Laurentian rocks. The average depth, from the head of the lock tc 
 the water suddenly deepens to eighteen feet, is eight feet, and the 
 feet. 
 
 I propose to make a double line of timber piers, 15 feet wide and 1 15 feet apart, for 
 the whole distance. Half of the width of each pier to be filled with earth lining and 
 sheetpiled, and the enclosed area divided into sections by water-tight bulk heaks. The 
 rock is seamy and would leak a good deal but by puttiug in powerful steam pumps and 
 shortening the length of the section to be laid dry in proportion to the leakage, it would 
 be perfectly practicable to keep down the water until the excavation was made to the 
 required depth of five feet. The stone would be used to fill the outside compartments of 
 the piers, and the excess deposited outside of that. The bulkheads would be removed, 
 and the whole thing would be an artificial canal 125 feet wide, and 13 feet deep, in the 
 bed of the river, while the piers would serve as guides to keep vessels from straying out 
 of the channel. I have been particular to describe this in detail, as a simlar method wiil 
 be proposed for submarine rock excavation wherever it may occur.

 The face and backing of locks IS estimated to come fnnii the neighboring quarries 
 of Cha/.y limestone at I'oini Claire of which the piers of the Victoria Bridge are built ; 
 filling of cribs out of the excavation. 
 
 This is unijiiestionably the best way to make the improvement, for were the pro- 
 posed canal located on the shores of the Island of Montreal, as has oeen sometimes 
 |)ro])Osed, the amount of under water rock excavation required to reach 15 (eet of water 
 from the shore, both above and below, would actually exceed that on the line 1 propost, 
 and we should have, in addition, an enormous amount of excavation on land, and an ex- 
 pensive bridge to build for the (Irand Trunk Railway.

 The head of the Saint Aiines Cana would be 23 miles from Montieal. Krom the 
 23rd to 24th mile, according to the surveys of \V. 1>. (lallwcy, C K., |)!actd in my hands 
 by the duiiartment, it has a depth of from 20 10 30 feet. Fiom ihe 24th tu the 26}jth 
 milt, the low water depth does not exceed 13 to 14 feet, and I am unable to say whether 
 the l)ottom is rock or sonic material that could, if required, be dredged. From the 
 2(jJ.jih mile to the foot ol the Carillon rapids at the 47 ^th mile, the channel is 50 feet 
 j,nd the navigation is straight and uninqieded.

 At Carillon the river is obstructed for 1 3 miles by a reef of calciferous sandstone 
 with only two or three feet of water running over it, excejjt in the ''Sickle'' channel, 
 about 150 ft. wide and 9 or 10 deep, and, as its name imphes, very crooked. The fall, 
 at the stage of water when we levelled it, was 8.75 feet. 
 
 'I'his has been overcome by the military canal, built by the Impeiial Government, 
 2 09 miles long ; locks uj), 23 leet, by two locks 128 x 32.5 x 55, and down again 13 
 to 15 feel by one lock of the same size, and is fed from the North river. The prism of 
 tiie canal is very irregular, being from 18 to 40 feet wide on bottom, and 50 to 80 at 
 surface, say 5.5 deep in the centre, gradually shoaling to each side. It runs from 5 to 
 16 feet cutting to water surface, principally rock. 
 
 The locks are in a \ery ruinous state, and cannot last many years longer in their 
 present condition. 
 
 The great amount of rock excavation necessary to enlarge this canal to the new 
 scale, its twelve to fifteen feet of unnecessary lockage, and bad location of the lower 
 lock, forbid us attempting to improve the present work. 
 
 I have located the new canal on the south shore of the river. The water is 25 to 
 30 feet deep up to the lower lock, which is at the foot of the current, near the house of 
 the late Judge Macdonald, Point Fortune. The passing basin is defended from the river 
 by a wall of stone laid in cement battering 2" in 12", backed by a bank of loose rock 
 out of the excavation, sloping 1 ^ to i towards the river, and the whole paved with stone 
 set on edge. The rolling dam stands on flat rock, free from boulders, and except in the 
 channel, the depth of water is not over two feet. It will have a slide for timber, ind the 
 height of water above its crest will range from 2.57 to 8. 11 feet. 
 
 By removing some fifty thousand cubic yards of rock between the upper lock and 
 the head of the rapid, this dam across the river could be dispensed with. On referring 
 to the map it will be seen that the proposed canal occupies the place of the side dam 
 just constructed. To gather enough depth of water to run deal and timber cribs, as we 
 are obliged to destroy this channel, we must provide a new one ; and there is no way so 
 practicable as to raise the water by a dam, which shall contain a broad and short slide 
 leading directly into deep water below. 
 
 The lock stone will come either from the Pointe Claire quarries, or those of Isle 
 Bizard. The loose stone for dam filling, out of the excavations, and the stone for the 
 wall, to be laid in cement, can be got out of the bed of the river in such size and shape 
 as will enable it to be laid up into a wall with scarcely any dressing. On this account I

 and cut through rock, about th? same depth. 
 
 We place the new lock in a channel between the island and the present lock, and 
 follow the line of reef with one dam, the depth, e.Kcept in channel, not being over two or 
 three feet. This dam has a slide for timber similar to Carillon.

 The bed of the Ottawa, at the foot of the Long Sault, which is an almost continuous 
 rapid for five miles, with a fall of forty-five feet, consists of calciferous sandstone, covered 
 with boulders (rom the Laurentian crystalline rocks. These are worn smooth and 
 polished by the water, are of all si/,es,and in many places entirely conceal the rock in 
 position. This makes so bad a foundation for artificial structures, that we are driven 
 perforce out of the bed of the river, and can do nothing lUt enlarge the present Gren- 
 ville Canal, which is generally well located on a strip of flat land lying between the high 
 bank and the margin of the river. 
 
 As has been stated, we leave the river i.i miles above Greece's Point, and lock up 
 at once to the (irenville level, in order to raise the bottom of the canal out of cutting. 
 The new line joins the old one in about a mile, follows it for about a mile and a half, 
 and then, to avoid rock cuttings, runs along the river's edge, which forms one bank, 
 while the other is formed by a stone wall laid in cement, backed by a bank of loose rock 
 out of the excavation of the head, and sloped i ^ to i toward the river, and paved. The 
 new canal follows the old line, cutting through the neck of land upon which the Village 
 of Grenville stands. Here, for 2000 feet, the width has been estimated to be 100 feet, 
 with sides nearly vertjcal. The embankments ('not river wall) are formed by dry bat- 
 tered wall, backed with earth filling. 
 
 If, instead of using these stone walls, laid on dry land, and in cement in river wall, 
 the embankments were dressed to a slope of i »4 to i and paved, the estimated cost of 
 this section ccild be reduced about $300,000. 
 
 •The Chute a Blondeau is one of the few points on the Ottawa where the phenomenon of "ice- 
 oacking" takes place. 
 
 The floating ice which has come down the Long Sault, is arrested by ihe sheet of still water below 
 this rapid, jammed under it and "packed," until an ice-dam is formed, raising the river some 25 to 30 
 feet above its summer level. 
 
 The effect of the proposed dam would be to form a still lake for some three miles above it, which 
 would be frozen over with a thick sheet of ice, and the "packing" if it took place at all, would be re- 
 moved some three miles up the river, above the point fixed fur the lower entrance of the Qr^nville Canal. 
 
The lock-stone can be brought from below by the present canals ; all the other 
 stone can be got out of the river, or near by ; and, as at Carillon, will require but little 
 labor to lay it into a good wall. All the rock from Carillion to (Irenville is roft, lies in 
 thin strata, and can he easily got out. I have considered $i per cubic yard as an ami)le 
 allowance, except at Chute a Mlondonu, where the rock is harder and there is less of it, 
 and I have called it .$125 per yard. 'I"he lock stone is easily dressed and can be carried 
 from the (piarries, to where it is wanted, m scows : distance 25 to ^^ miles. I have con- 
 sidered that $12 for face and $6 for packing, averaging $8 would be sufticient. 
 
 .'\t the head of the Long Sault is a great sand-shoal, partly dry at low water ; but follow- 
 ing close to the norlh shore we have 24 to 30 feet. I'rom (irenville to Ottawa, the river 
 runs in a level valley, with low shores of blue tertiary clays ; a considerable extent is 
 overflowed by high water, and covered with sand deposited by the river. 
 
 The width is from one to two thousand feet, and the channel depth 30 feet, until we 
 get to the "tlreen Shoal," some 8 or 9 miles below Ottawa Cil/. Here a ralciferous 
 sandstone reef runs clear across the river, diminishmg the f^tpth at low water to eight feet 
 for a length of five hundred feet. 
 
 It will be necessary to pursue the same course here, that has been recommended at 
 St. Annes, and remove the stone by a coffer dam, the sides of which should be left for 
 guide jMers to indicate the channel. Helwen this place and Ottawa City, there are some 
 sand shoals that must be dredged, but no more rock. 
 
 The sum estimated for the improvement of this section is$i3r),io5. 
 
 The i)lans of this part ot the river furnished me by the Department from the surveys 
 of Mr. dallwey being unfinished, I have obtained the distance from (Irenville to Ottawa 
 City through the kindness of Sir William Logan, who calculates it at 55.25 miles in a 
 straight line, .\llowing for the bends of the river, I have called it 56.07.

 At Ottawa City the river is interrui)ted by rapids and falls for 6 36 miles, having a 
 decent between Ottawa harbor and Des Chenes Lake of about 60 feet, *36 of which are 
 taken uj) by the Chaudiere, a magnificent f.ill which affords one of the finest water powers 
 on the continent. 
 
 Several lines had been previously surveyed for this Canal, but I have preferred to fol- 
 low the river, shortening the length of Canal required, and much diminishing the amount 
 of rock-cutting, and consequent expense. IJut little land is overflowed, and that chiefly 
 swamp. Two mills would be destroyed, (Sparks, and the Britannia,) but the new \mv\- 
 leges would be better than those now existing. 
 
 Stones for the dams can be got out of the excavation, and e.\cellent lock stone from 
 the Trenton group ov limestones, abounds close at hand. 
 
 Lake Des Chenes, or as it is sometimes called, Chaudiere Lake, is 26.69 miles long, 
 and varies from half a mile to two miles in width ; and according to Mr. dallwey, its 
 general channel depth is from 20 to 30 feet of water. 
 
 Below the river Quio the channel is crooked for a short distance, the depth 14, 16 
 and 18 feet, and some points might have to be taken off. From there to the foot of the 
 Chats there is 25 to 30 feet. 
 
 * At the time we took our levels, the fall between Des Chenes Lake and Ottaw.i harbor was 59.5 feet 
 but the difference between the recorded levels of low water is 63 feet. If this is correct, of which I have 
 some doubts, it is owing to the greater evaporation on the longer level below. It has been thought 
 prudent to provide for sixty-three feet of lockage. 
 
 Below, the river rises more than at any other point, some 20 to 24 feet. This is attributed to the 
 /act that the Gatineau, a very large river, comes in a little below at right angles to the main river, and 
 draws back its waters.

 This, it will be observed, differs entirely from the old route of the Chats Canal. A 
 considerable proportion of the exc.ivatiol; necessary to finish that w. irk to the sc.ile origi- 
 nally contemplated (60 feet wide, and 7 deep,) has been done, but it forms a very 
 insignificant amount of that retpiired for the new scale. The canal ends below m Mig 
 l>ay, a sheet of water about a mile long, ijuite shallow, and with a bottom of gneiss rock. 
 
 The ilepth at low water for 700 feet is not over 5.5 ; for 1000 feet not (jver <S 5 ; and 
 for 1600 feet, at the entrance, not over 6 or 7 feet, although most of this is |)ri)l)ably 
 clay, and could be dredged. 
 
 The only way a sufficient depth can be got excejH at a ruinous expense, is to throw 
 a dam across the mouth of Big Bay, and raise the surf.ace, placing a lock on what is called 
 Hudson's Point. 
 
 •My estimate for the compli'tion of the present Chats Canal on this plan, to a 
 scale uniform with the rest of the river, is $1,465,439. [See aiinendix ] 
 
 'I'here being some difficulties in ascertaining theamount of work done, I have credited 
 the work with the whole amount expended, as per last re!) irt of l)j|)artment of i'ablic 
 Works, amounting to .$ 324,000, leaving a balance to be yet expended of ,$1,141,439, 
 
 My estimate for the new work has been stated at $681,932, showing that it would t)e 
 a saving to the Province of $459,507 to abandon the work alreaily done on the old rou;e 
 and take the nevs. 
 
 The length of Canal on the old loute is three miles, and is (]uite crookfd ; on the 
 new rojte we have only ,"„ of a mile, being the locks and i)assing l)asin. The rest of it 
 will be as good navigation as any part of the river. I have no hesitation in recommending 
 the adojition of the new route. 
 
 We cross the Chats Island with four locks, as stated above and run a low liam along' 
 the line of reefs at the head of the main fall, raising the surtace enough to drown out 
 currents up to our upper lock. The water does not exceed three feet in dejjth on the line 
 of dam, cxce[)t in the channels, and there are so many islands to work frtim. that the 
 difiiculty of building a dam here is not so great as at first sight would ajjpear. 
 
 The depth of water will not be less than from 20 to 25 feet from this point to the 
 upi)er lock and dam. This brings us to the level of Chats Lake, and we have iS to 30 
 feet depth as far as the reef at the present head of the rapids. At what is called the canoe 
 channel, there is now a depth of ten feet, but it is narrow and crooked. It sbjies above 
 into 13 feet of water in about 300 feet, and, below, pitches off at once into iS feet of 
 water. After the dam has been built below, and water stilled, it will be necessary to put 
 in a coffer dam here, and remove some rock, which is chiefly crystalline limestone, leaving 
 the sides of the dam for guides, as at Green Shoal. 
 
 The lock stone for this work should come from the quarries of Black River limestone 
 on Des Chenes Lake. Stone for dams can be got in the neighbourhood. I have estimated 
 the face stfine at $12, and the backing at $6.50 per cubic yard, or an average of $8.25. 
 
 Up to this ])lace whatever rock excavation has been necessary, was through Silurian 
 lime and sandstones of soft texture. But this rocky barrier, over which the river tumbles 
 in some thirty different chutes, is one of the Laurentian series, and consists of hornblendic 
 gneiss, mica slates, and crystalline limestone. The strata are considerably inclined, dip 
 in the direction of the current, and the "strike" is generally at right angles to the direc- 
 tion of the stream, as may be plainly seen from the course of the reef. 
 
 These rocks are all hard to work. The crystalline limestone is much the easiest, 
 and I huve allowed $1.50 per cubic yard for it. The mica slates, and particularly the 
 hornblendic gneiss of a greasy texture, and greenish red color, such as is found at the 
 lower end of the canal excavations, are hard to drill, and require much power to break 
 them up. The price which I have allowed, and which is proportioned to the rock prices 
 over the rest of the river, is $2.50 per cubic yard. 
 
15 
 
 The Chats Lake is a fine slict'i cjf water i8 miles long, and from half a mile to three 
 miles wide, with a channel depth of from 25 to 30 feet. 
 
 From the head of this Lake to the head of the Calumet Island, a distance of 31.07 
 miles by the North or Calumet f'hanne!, and 24.79 miles ^'X 'he South or "Rocher 
 Feiidu" channel, the river has a total I'nll ot 10J.4.S feet, and is much obstructed by 
 ra|)ids and stioals. On the north channel more than half the full is concentrated at one 
 point, the Clrand Calumet Falls, and there are longer stretches of still water. The south 
 channel is a continuous rapid for much of the distance. 
 
 In decidm^ between theso two channels, several thing were apparent without 
 further instrumental survf-y : 
 
 I. The Calumet was 6.28 miles longer than the other 
 
 II. From the head of the Calumet Falls to La Passer 17 miles, the bed of the river 
 is cut through sandy alluvial soil, is very crooked, and is filled with shifting sand-bars 
 and shoals, that would have to be dredged, not only once, to open the navigation but 
 continually to keep it open. 
 
 III. The timber slides now occupy the Calumet channel, and as there is not room 
 for both timber and vessles, if we take this channel new slides must be built on the 
 Rocher F'endu, 
 
 I v. The nature of the ground at the Calumet Falls would require three locks in 
 
 combination. 
 
 rhe very important question of cost could not be determined without making loca- 
 tion of locks and dams on both channels, and estimating on each. 
 
 The Lock at the Snows is common to both routes ; the lit't at the upper one at Por- 
 tage du Foi t, and the height of dam, would have to be increased six feet. Two locks 
 and a dam, and o 28 miles of canal at the "Mountain" chute, and five locks and a dam 
 at the "(Irand Calumet." raising the water to the level of the river at the head of the 
 island. 
 
 Here the only i)Ossible location for the canal s on the site of the present slides. A 
 ravine to the left of the fall was surveyed in 1857. 15ut even by combining all the five 
 locks at the lower en I, there would be fifty feet cutting for one mile, which, even for a 
 canil of a hundred feet wide, would require the removal of nearly a million yards of 
 rock. — This is, of course, impracticable. 
 
 In comparing the cost of the two routes, the lockage is the same ; and the difference 
 of dams is not enough to affect the estimate materially. But the "Calumet" route would 
 have in excess, 
 
 167,500 cubic yards rock cutting, at $1,50 .... 
 1,000,000 " dredging, at 35c ..... 
 
 Shewing a difference of cost of 
 
 over the Rocher Fendu route. 
 
 Taking all these things into account, I have no hesitation in recommending the 
 Rocher Fendu for improvement, and shall describe how it can be done.

 The rapids of the Ottawa are caused by reefs. 
 
 These are the remains, more or less worn away of the rocky barriers which once 
 separated the different lakes In the limestone formations; the whole bar has generally 
 been washed away, leaving an entirely submerged reef. But among the Laurentian rocks, 
 the river cuts channels through the softer veins, leaving the harder rocks protruding 
 above water in the form of islands. The "Snows" is a place where even the reefs be- 
 tween the islands have been worn away, so that it is now merely a contraction in the 
 channel, forming what hydraulic writers call a ''discontinuous weir."

 In summer the volume of water is only sufficient to dam itself u|) some six or eij,'ht 
 inches,* f(jrminn a sli^iht ripple; but in floods the water above rises from three to four 
 feet, making a rapid too strong for steamboats to ascend. 
 
 Three methods oi impiovement have been suggested: — 'I'o raise the (,"hats Lake 
 and drown out th;,- rapid ; — To remove the islands which obstruct the channel ; — To put 
 a lock in one of the channels. 
 
 When a river channel is contracted, the water dams itself up until it has attained a 
 head sut'ticicnt to give itself velocity enough to pass through a narrow passage. Raising 
 the water below will not prevent this from taking place, unless it is raised enough to give 
 it an area of flowai^o ecjual o that of the avi'rage chinitel of the river. To do this here 
 would rc'iuire a lit't of the (Jhats Lake so great as to be inadvisable. 
 
 '!"() enlarge the area fnjm S,4oo to 20,000 s(jiiare feet, l)y removing obstructions, 
 would rnjiiire too nuicb rock ixcavation. 
 
 We are, therefore, reduced to the third plan, as recommended i)y I'. \\. Norman, 
 C. 1^ . in his report to the dei)artment last year, and must i)Ut a lock in one of the chan- 
 nels. The (!anoe Channel has been selected as the best ; and the Steainlvoat Channel 
 will be left open for the decending trade ; but ail the others will be closed by low dams. 
 This will raise the water si.x feet f above its present level. In the spring the high water 
 will pour over these dams. 
 
 I have gone somewhat more into detail in describing this place than its imjjortance 
 would seem to warrant ; because, from its being the line of the present steamboat naviga- 
 tion, it has been much discussed, and many plans suggested for its improvement, both by 
 professional and amateur engineers.

 The dam at Portage du Korl will drown out the small ra|)ids known as the "Split 
 Rock and Tables," and give sufficient dejUh of water as far as the Rocher-Fendu Lake 
 which, according to the surveys of T. E. Norman, Ksc;., is 30 to 60 feet in de|)th. The 
 distance from I'ortage du Fort to the head of this lake, where we have a lock and dam 
 is 7.35 miles. A distance of 1.61 miles takes us to Long Rajuds, where are two locks 
 and a dam. The lift of water, 17 feet, drowns out La IJarriere, .Muskrat, and Mice 
 Rai)ids, all of which have channels worn through the reefs, so thai there will be no 
 necessuy for submarine rock excavation, while ihe shores are bold and high enough lo 
 ))rcvcnl much land from being overflowed. We are now at the foot of what is called 
 l.afontaiue IsLmd, and here the river is divided into three channels. It is proposed lo 
 follow the south ciianucl, and by building a tight stone dam above Black's Falls al the 
 head of the island, to shut out the flood water and drive il down the other two channels, 
 only admitting enough for navigation. Otherwise, the amount of water discharged in 
 flood it so great in |)ro|)ortion lo the contracted size of liie channel, that il would be 
 difficult either to build structures, or use them after they were done. By availing our- 
 selves of the existence of these other channels to take o(T the surplus water, we can lay 
 our work without coffer dams, and regulate force of currents as we please. Five locks 
 and three dams take us lo the head. 
 
 .Some of the crystalline limestone is good enough for locks, some stone will come 
 from the quarries on Allumettes Island above, and jjerhaps some from I'ortage du Fort 
 or Chats Lake. 
 
 The rock on this part of the river, although of the Laurentian series will not be so 
 hard as that al the Chats, owing lo the greater amount of ciystalline limestone, and lo 
 the preponderance of felspar in the gneiss, which is easily acted on by the weather, and 
 causes the gneiss to crumble, and become broken up. I have estimated the rock exca- 
 vation at $1.50 per cubic yard. Stone for dams can be got in the locality. 
 
 From the head of the Calumet Island to the foot of the Allumettes Island, the river 
 expands into what is known as Lake Coulonge. At its foot the river is divided into 
 several channels and islands. The main body of water passes on the west side, and has 
 not been sounded until this year. The other channels are quite shallow, but this has 20 
 feet and over, except at one point, where, for five hundred feet in length, there is not 
 over ten feet at low water. 
 
 Through the remainder of Lake Coulonge according to plans made under the direc- 
 tion of Mr. Shanly, and furnished me by the department, there is 25 to 30 feet in depth 
 of water. 
 
 The river is again divided into two channels by the Allumettes Island ; the Northern 
 of which, known as the Culbute, is much the better suited for navigation. 
 
 This Channel is narrow with hold shores, and the fall 18.26 feet, is concentrated into 
 rapids at the head, the Culbute and I'lslet. For nine miles from the foot of the islandt 
 
IH 
 
 Up to a slight rapid ot five or six inches fall, known as the (Jhapeau, and caused by a con- 
 traction of the channel, we must follow the natural hcd of the river, which is somewhat 
 crooked, and will rec^uire a considerable amount of dredging, |)articulariy at the mouth of 
 lilack Kiver, a turbulent stream which brings down nmch sand during spring freshets. 
 It is probable that there will be some boulders, and points of reef below water, to be 
 removed. l*'or the improvement of this section there has been estimated the sum of 
 $262,514.

 The lift ot 1 1.5 feet at the Chapeau, gives good navigation for 5 85 miles to the foot of 
 rislet. Here a tight dam of masonry in cement, as at Hlack's Kails, will keep out the 
 flood waters, and drive them down the broad Pembroke channel, and the lock is located 
 in the channel between the island and the north shore. 
 
 This raises the surface of the water above I'lslet to the level of the river at Fort Wil- 
 liam, and drowns out the Culbute, which rapid darts through a narrow gorge in the 
 rock, not over eighty feet wide, with high perpendicular cliffs on either hand. It will be 
 necessary to tak : three or four feet off the top of the reef for about fifty feet in length. 
 This can be done by putting in a short temporary dam at the head, after the water is 
 raised and made still by the dam below. Then, on opening the gates of the lower dam. 
 the bed of the river will be laid dry at this point, and the rock can be removed, aftt r 
 which the coffer dam above must be taken out. 
 
 The lock stone for these works is estimated to come from the quarries on .Allumeltes 
 Island, four or five miles from the work. Stone for dam can be got near by. 
 
 Although it does not properly fall w 'n the limits of this report, yet I shall take 
 the liberty ot calling the attention of the c mmissioners to the fact that the expenditure 
 of the above named sum of $243,507, would extend the i)resent steamboat navigation 
 from Des Joachims to the head of Calumet Falls, a distance of 75 miles. From thence 
 the macadamized road just finished by the department, would avoid the 8.41 miles of 
 obstructed navigation, between the steamboat landing above the Calumet and Portage du 
 Fort, the present head of navagation on Chats Lake ; avoiding the expensive and tedious 
 detour of Muskrat Lake. An additional expenditure of$So,ooo would build the lock at 
 the Snows. The dam would not be required at present. 
 
 I know no point above the City of Ottawa where so little expenditure would do 
 so much for the local trafHic, as at these places. 
 
 From the head of Culbute to Fort William, 5.3 miies, the river is much broken up 
 by rocky islands, but according to the soundings laid down on the plans of Mr. Shanly, 
 there is a deep, although somewhat tortuous channel. 
 
 From Fort William to the Rapid des Joachims, we have the fine stretch of water 
 known as Deep River ; this is very straight, one to two thousand feet wide, and 27.6 
 miles long. The depth is very great, and said to be over 100 fathoms in some places ; 
 the shores are very bold, and the general character of the scenery resembles that ot the 
 Saguenay on a small scale,

 This rapid is 1.84 miles long and falls 26.4 feet. It comes nearly at right angles to 
 the general course of the river, which, if prolonged, would run through a series of lakes, 
 and strike the river again about three miles above. A line of levels were taken by Mr. 
 G. H. Perry, to see vhether this chain of lakes might be followed and a canal cut through 
 
ii) 
 
 the ridge, (lividin^ thorn i'rom the river. Although the distance in less than a mile, the 
 cuttinK even with |)ru|)()SL-d dam at head ul Des Joachims, would average 20 feet, which 
 would re(|Uire the removal of over 400,000 cubic yards, principally rock. [lonce we pre- 
 fer to follow the north shore of the river itself. 'I'he rock occupies the place of the slides, 
 which will have to he removed to the south side of the island, where mere is a very good 
 place for them. 
 
 Face stone of locks is estimated to con>e from Pembroke ([uarries. All other stone 
 can be obtained in the neighbourhood.

 From the upper lock at Des Joachims, a distance of 13.68 miles brings us to a series 
 of small rapic's of 3 feet fall, where we put in a lock on the south side of the river, and a 
 dam. It is necessary to raise the water eleven feet on the foot of the Rocher Capitaine ; 
 and to avoid making the dam at the Joachims so high, this intermediate dam at McSor- 
 ley's is designed. 
 
 The face stone of the lock must come from the Pembroke (|uarrics. backing, and

 The Rocher Capitaine, which it is proposed to overcome in the above manner, is 
 one of the largest rapids on the Ottawa, falling 40.9 feet in a distance or 1.35 miles. The 
 locks are located on the north side of the river. The bank is composed of an immense 
 mass of boulders of all sizes worn smooth by the water. It covers a space of about two 
 scjuare miles, and ris<!S some sixty feet above the water. Fortunately, between these 
 boulders and the river there is a strip of solid rock in position, upon which we place the 
 locks and canals. The bottom ot the river is smooth rock, the depth where the dams run 
 is not great, and, except that the upper dam must be long, there is no special difficulty in 
 overcoming this rapid. 
 
 The face stone of locks is estimated to be got from the Pembroke cjuarries ; but the 
 expense would be less, if the canal, hereafter described at the Deux Rivieres, were built 
 first, as the stone would then come from the quarries above it, without transhipment. 
 The rest of the materials can be got near the work.

 The rapids, known as Deux Rivieres, Trou and La Veillee, occupy 3.15 miles, and 
 fall 31. 1 feet. The fall in the river, from their head, to Johnson's Rapids, a distance of 
 17.85 miles, is 9.7 feet, most of which occurs in the rapids, at the Rocky Farm, which 
 occupy 4.7s miles. It was thought best to put in a high dam at the Deux Rivifcres and 
 then back the waters to Johnson's Rapids, as the facilities were greater for that mode of 
 construction, than for putting in another dam and lock between the two, and the amount 
 of land overflowed is quite insignificant. 
 
 The locks are situated on the south side of the river, on a flat piece of land, well 
 suited for their location ; the lock stone will come from beds of a yellow or buff colored

 "On connnenciii'; exaim'nations lor a work of the contemplated <:haracterand maj;ni- 
 tiide of the improvement of the Ottaiva and i'Vench River waters, the fiistthinj; presenl- 
 in.L; itself as indis[)ensibly necessary, was to obtain a reliable section of I'"rench River. 
 Lake Nipissini^, and the sunnmt or height ol laiul between Nipissini; and Trout j.ikes. 
 The e.\aniinations were commenied at the principal mouth of the middle outlets of 
 French River on the joili November 1858. 
 
 "This debouchment of Fiench River is entirely land locked. To the west lie a lari;e 
 grouj) of islands known as the ''liusiard Islands," which completely shelter the mouth of 
 the river from thu westerly and the southwesterly winds of ('ijoii;ian iJ.iy.The mam land 
 affords protection from the northerly winds. 
 
 "The channel to the entrance of French River lies at the northerly extremity, and 
 close under these islands. There appear to be several deep and broad channels divided 
 by Kunken reels, and I am -jonfident that a spacious entrance cm be marked out, free 
 from these treacherous sunken rocks which mark the whole coast ol ("jeoii^i.ui Hay.* 
 
 "l""roin the mouth of l'"rench River, for the distance of j.j.j miles, the river is 
 straii't. broad, and deep ; the banks bold, and the i^ray crystalline gneiss rocks rise 
 perpe 'icular out of the water, ami make it resemble more the deej) bays of the lake 
 than ii mouth of a river. 
 
 ".\ his tiisiance from the bay, the river makes a turn nearlv at riylu angles fo the 
 right, and necomes quite narrow ; and here *'I,es I'etites Dalles Ra|)ids.'' form a barrier 
 to navigation ; the fall at this jioint is six feet. Tlie rapids are about ninety feet in 
 width, and it is about 1 ido feet from deej) water below to deep water above. The rock 
 on the north rises nearly pjr|iendicular to the height (>f ninety feet, and on the south side 
 with a gentle slojie. to the heigiit of twenty feet, in a distance of one hundred and twenty 
 feet, and then rises abrujjtly into broken cliffs. 
 
 "I'roin "I.es I'etites Dalles" we continue our course nearly east for the distance of 
 one and a (juarter miles ; here we find two large channels, one continuing directly on the

 tion is dangerous to dlo.se who are coasting, and have to pass over the ends of the reefs , there can alway.s 
 he found a direct entrance between them, unobstructed by shoals or sunken rocks. I have myself .sound- 
 ed from the fool of thel'elites Dalles, out into the open laUe, and found a gradual increase of 6,7,8, 9 and 
 10 fathoms, where my soundings ceased, about half a ni.Ie Irom the point where the river may b" saiil to

 " We imrsiK'tl our exainiiiatioii up the latter lor tiie distance of three miles to ' Lac 
 cie liieulV a body up water about three miles long by one mile in width, thickly studded 
 with islands; here we enter on utu' easterly direction for Lake Ni|<issing. 
 
 "At the distance of 10.17 mi.es from " Les I'etites l>alK"<,"we fmd a small rapid of 
 two Icel fall, about 200 feet wide, ami the water from (> to S feel deep at a low stage. 
 
 " .'\t a further distance of .v'^- miles, another small rajiitl of seven-tenths of a foot 
 fall, is encountered. 1 oS miles furliier, we reach " Lu (liand Recollet Rapids, with a 
 fall of (i.So feel. 'I'lie width of the river at this |)oint is two hundred and fifty feet. The 
 bank on the north side rises nearly perpendicular to the height ot one hundred and lilty 
 teet above the water. (In the south side there is a table scarcely sufticieiU in length and 
 lireadlh for the lock. I'lie rest ( f the bank rises perjiendicularly eighty or ninety feet. 
 
 " .\fter leaving ' Le Ciiand Rirollei' we havt- a reach of 17.02 miles to the ' Rai)ide de 
 I'arisien,' where there is a fill of 1.20 feet. In the next .^.lo miles, we pass the ' I'etite 
 l''aucelle Rapid,' fall .^.4 feet. ' Rapide du Huison,' fall 3 ;^ fett, '(Irand I'aiicelle Rapid,' 
 fall 5.f) feet, and ' Rapide du Pin,' fall 2.(1 feet. In tracing the distance we change our 
 course hom east to north. .At the head of the ' Rapide du Tin,' the course agatn becomes 
 easterly, and continues 30 to the foot of the 'Chaudiere Rapids,' a distance of 7.57 miles. 
 
 " The fall between the foot of Lake Nii)issing and the still water in i'Vench River 
 below the rapids, is divided into fine cascades and rapids. The total fall is 2fi feet in a 
 distance of I. f) I miles. The b.mks at the water's edge of the rapids are mostly low ; 
 rising grach:;;l|y for the distance of sixty to one hundred feet back; then they rise abrupt 
 into high rocky cliffs. 
 
 '' I'"rom the mouth of I-'rench River on the (Georgian I'ay, to its source at the outlet 
 of Lake \i|)issing, the distance is 4752 miles; the ascent at low water is (10.3 (eet, 
 making the elevation at Lake Nipissing f),v|.3 feet, above tide water. 
 
 '■ The distance through Lake Xipissing is 30.4.1 miles. I'etween Nipissing and 
 Trout Lakes two routes were carelully examined. 
 
 "The first, by the valley of the ' Riviere des \'ases,' 6. 69 miks in length, 
 
 '•The sicoiid. by the \alley of the ' ()jibwa>sippi,' .^.l«) miles in length, with an 
 ascent between Nipissing and I rout Lakes of twenty-four and a-half feet. The water- 
 heads ot the .\lattawan aw ^^S.S (Vet above tide water. 
 
 " In coin|)arative cost these two routes have no relative nuT'ls. liy the ' \'ases ' 
 route, tlure are four miles of cutting, any one of which would cost more than the whole 
 line ot the ' Ojibwaysippi ' route. 
 
 " Here we |)ass ths watershed between the waters of the Ottawa and Lrench Rivers. 
 
 " .After entering ' Trout Lake ' our course bore south of east. The length ol this lake 
 is S.43 miles, and averagi' width one mile. .\t the foot of this occurs a narrow ridge of 
 rocks which divides it bom Turtle Lake. The fall is nine-tenths of a fiot. The rapid is 
 about ten feet wide, and not over eii^hteen inches in dei)tli. We then pass 3.J.S miles 
 through Turtle Lake, nearly on a due east course. This lake averages about half ,1 mile 
 in width.- I'.issing down the outlet of Turtle Lake, we change our course to the north in 
 the first two miles; iheiux eastwardly, and at the distance of 3.74 miles, we enter Lac 
 Talon The descent between these two last-named lakes is 21). ij feel, giving Lac Talon 
 an elevation of 6jS feet above tide water. The outlet has a succession of small rapids 
 with dee]) still ponds between them. 
 
 " The course through 1/u; Talon lies about south-east, and is 7. O3 miles in length, 
 with an average width of one nnle. Lac 'Talon discharges through a Ihime-'.ike chute of 
 21 feet in width, with three beautiful cascades before reaching the level below, 'The 
 total fall is 42.7 feet. lOach side of the chute is bounded by high and barren syenite 
 cliffs. 
 
 " From the foot of 'Talon Chute, the course of the waters changes to the north, until 
 they reach the foot of the i'aresseux Chute, 2.28 miles ; in this distance there is a scries 
 of i)onds, or basins and rapids, making a descent to the head of the I'aresseux Chute of 
 21 feet. .At the I'aresseux Rapids and Chute there is 33.8 ft. fall in a beautiful cascade. 
 
 " After passing the I'aresseux Chute, the river passes between bold cliffs of syenite, 
 which present the appearance of rough and massive masonry, towering about 150 
 feet above the surface of water. The river is narrow and deep between these iron bound 
 
22 
 
 barriers, in places only 105 feet wide. It soon widens to 250 and 300 feet in width. 
 
 " From Lake Talon to the river below Talon Chute, a route was examined, leaving 
 Talon Lake about one and a half miles above its frot. At the distance of 1500 
 feet from Lake Talon, we encountered a summit of fifty feet in height above the lake, 
 and about 2000 feet in length ; after passing this summit, we dropped down into 
 a chain of small ponds running nearly east, and emptying into the Mattawan about one 
 half of a mile below Paresseux Chute. The length of this line is 4.15 miles, and more 
 direct than the channel of the river, and well adapted for the line of improvement, were 
 it not for the heavy cutting at the summit. The exaromations, estimates, and plans of 
 this route were made with the same care and attention as marked those of the main 
 route. 
 
 " The river route is 1.06 miles longer, but is estimated to cost $564,000 less, and is 
 recommended. 
 
 " From the foot of the Parasseux Chute to the mouth of the Mattawan, the course 
 is direct and nearly due east. At 2.64 miles we reach the ' Rapide des Aiguilles,' with 
 & fall of four-tenths of a foot ; 0.71 miles further east is the ' Rapide des Rochers,' with a 
 descent of 4.8 feet. At this rapid the land on each side is low and swampy for the dis- 
 tance of six to eight hundred feet back. Passing down with a strong current for 1.20 
 miles, we reach the ' Rapide de la Rose,' fall 5.6 feet. At the further distance of seven- 
 tenths of a mile is the ' Rapide des Epines ' fall 5.6 feet. 
 
 " From the foot of the ' Rapide des Epines,' we find a broad and deep stretch of 
 river 5.5 miles in length, with the same rugged, syenite cliff-like banks ; at the 
 foot of this fine stretch of water, we reach the ' Lac Plem Chants Rapids and Chute,' 
 with a fall of 16.9 feet, in the distance of four-tenths of a mile. At the further distance 
 of 2.40 miles, the Mattawan enters the Ottawa waters. In this distance we find three 
 small rapids with a fall of 5.4 feet ; making the total descent of the Mattawan 169.8 feet 
 in the distance of 39.79 miles, and the low water surface at the mouth 489 feet above 
 tide. 
 
 '* A tabular statement of the low water section of these rivers. &c., is annexed. 
 
 " The characteristics of the French River and Mattawan waters are similar, each 
 being a succession of pools of wide, deep and still water, separated by short falls and 
 rapids ; in many of these pools there is no perceptible difference of level. 
 
 *• The shores are principally lined with the ever-prevailing syenite and gneiss, rising 
 abruptly out of the water into bold precipitous cliffs, covered with a dwarf growth of 
 timber. 
 
 " By the mode of improvement proposed, that is by locks and dams, which is the 
 only feasible plan of work to render these rivers navigable for any class of vessels that may 
 navigate the western lakes ; th-j characteristics of these rivers will, in a great degree, re- 
 main the same as now, after the completion of the improvement. 
 
 " My early attention was called to the question of supply of water, ' upon which the 
 success of the whole project depends,' and more particularly directed to the practica- 
 bility of the plan of elevating Lake Nipissing to the summit level, as proposed by Mr. 
 Shanly, both by the general instructions of the board of Public Works, and by your

 " Mr. Shanly, in his report on the ' Ottawa Survey,' says * It may at once be stated 
 that the summit does not fnrnish water sufficient to meet the demands of even a far in- 
 ferior scale of navigation to that which the general character of the route would warrant 
 us in looking forward to.' 
 
 " To this opinion of Mr. Shanly's, respecting the supply of water from the summit, 
 that is from Trout and Turtle Lakes, I agree ; and after a careful examination of the 
 whole subject, I would recommend the following plan for 
 
 SUPPLY. 
 
 " For the supply of water it is proposed to raise Lake Nipissing 9.46 feet above 
 high water, and lower Trout Lake 7.85 feet, and Turtle Lake 6.95 feet, and Turtle Lake 
 outlet to the same level, and to raise Lac Talon 20.95 feet, which brings it up to the same 
 height, making a summit level for navigation of 57.12 miles in length, with an area of 
 watershed of 3165 square miles, and a reception basin of eighty miles in length, and 
 
Jd 
 |n- 
 
 
 varying from one-lialf of a mile to 12 miles in width. i;iving a surlare nf alxjiU three 
 hundred and thirty s(iiiare miles, liy this arraniieinent it does not bec-ome necessary to 
 make any provision for a stcjraue r-.servoir. I'he waters of Lake Nipi.ssin;^ are sulticient 
 tor any scale of navig.ition, awd for all time to come. 
 
 ".\Uhoiigh the (juantity ot water rer^nired to maintain a steady flow of any given 
 dei)th through open sluices ol regular width, may he calculated with a considerable degree 
 of accuracy ; yet, in the case of an open river of uneven hottijiit and irregul.u- width and 
 declivity, like that of the I'rench river, it cannot l)e expected thatanything more than a 
 rough appr.iximation can be obtained ; uncertainly must attend the measurements, and 
 conseiiuently the results fcnmded thereon. 
 
 " I'ortunately for us in this case, the (juantity of water discharged from Lake Nipis- 
 sing through the I'rench River is so large that any error (jf this kiml could not affect the 
 question of su|)ply for any scale of navigation that may be adopted. 
 
 "The quantity of water found, by careful gauging, to he fl )\ving in I'Veiich River at 
 a low stage, was nme thousand live huruireti (1^,500) cubic feet [)jr setond, or eight 
 hundred and twenty millions eight hundred thousand (820,800,000) cubic feet in twenty- 
 four hours. .\ssu;;iing the locks to be 250 x 5c x 12, and that I'llty lockages are made 
 each way in twenty-four hours, it woukl retiuire fifteen million cubic feet of water, or less 
 than one-hftielh part of the supply. 'l"he whole amount of water tlowing is e(juivalent 
 to 5,472 lockages each tweniy-four hours. This, at once, sets at rest any idea of the 
 neix'ssily of a st(jrage reservoir. 
 
 " Tliereare i)Ut tew objec ticiuible features to this mode of supplying the necessary 
 water for navigation, and of raising Lake Xipissing to the heigiu above stated. 'I'he first, 
 and almost the only one, is the overflowing of the lands bordering on the Lakes. 
 
 " The entire southern shore of Lake Nipir^sing, ea^t of the Chaudiere Portage, is 
 bounded by high barren rocky cliffs, with a scanty growth of evergreens covering the 
 whole, except a strip on the east end of the lake, about eight miles long, i\H(J varying 
 from one tenth to one-founh of a mile in width, one-half of which is annually /nundated 
 by the Spring freshets. The shore of the Ivisl l!ay and the east end of the Lake, for the 
 distance of ten miles, will be overtlowed ; a large portion <jf this tract is annually sub- 
 merged by the freshets, and nearly the whole is one tvicnded T.uiuirac swampi, or an 
 .\lder marsh. The north shore, for two-thirds of its le' is high, and out of the reach 
 
 of this height of waic^ 
 
 ■' In the vicinity of the Hudson's l!ay I'ost, at the mouth of the Sturgeon River, the 
 large-it iiact on the holders of tlie Lake will lie submerged, say from t(-'n to twelve miles 
 in length, and liom two to three miles in width ; (.ne-third of the tract is low open marsh, 
 about one-third swamji annually o.ertlowed, and the remaining third tolerably iair land 
 for agricultural purposes. 
 
 " In the Western l!ay tlierc wan occasional narrow strip that will be dr<jwned out. 
 Taking the wlmle land that will be drowned by the raising of Lake Xipissing, it will be 
 inconsiderable when comjiared with the length of shore, and that l.)iit of small value for 
 agricultural purp(jses. 
 
 " Raising Lake \ii)issiiig to the height of Trout Lake, wou!d lessen the cost of C(jn- 
 struction about one million dollars, and reduce the lengih of canal on the summit to less 
 than om; and tliree-(]uarter miles, \sould increase the lockage 15 6 feet, and overflow 
 three times as much land as the plan propositi. 
 
 " The land, being in a district uninhabited, except by a few Indians and the servants 
 of the Hudson s l!ay Com])any, cannot be looked upon as claiming much consideration, 
 in deciding uiion such an imjicrtant quevtion. The objectionable features in elevating 
 the water of Lake Ni|)issing to the level of 'I'rout Lake, are :— 
 
 ■' First, the low banks along the southerly shore ,vest of the Chaudiere Portage, and 
 also for two miles to the east of the I'ortage ; Second, the large fissures and crevices in 
 the rocks, affording an opportunity for the escape of water, scarcely to be estimated : in 
 tact this might prove so large as to cause any attemjit to meet such an emergency 
 entirely abortive, and without a more careful antl minute instrumental examination of the 
 entire southern shore west of the I'ortage, than my limited time would permit me. I 
 should be unwilling to recommend the raising of Lake Nipissing higher than contemplated 
 in the plan proposed. 
 
 " The raising of Lake Talon can be accomplished without overflowing the adjacent 
 land to any considerable extent.

 "'I'lie arrangciiKiit of Locks and Dams connected will he as follows : — 
 " At Les I'ttites Dalles, on lock, fourteen feet lift, on the south side of the river. 
 "To establish the level above the I'etites Dalles, it would be necessary to construct 
 seven 1 )ams across the several outlets of the French River. 
 " 'I'otal length of Dams, 1,535 f^^-'t- 
 Aggregate S|)ill, 1,595 feet. 
 Crest of Dam, 8.50 leet above low water. 
 
 " These Dams throw the water up to " Le (irand KecoUet Rapids," fifteen and one- 
 tenth miles, drowning out two small rapids, so that no excavation will be necessary to 
 give the recjuisite depth of water. 
 
 " At ' Le (Irand RecoUet,' one lock of 13 feet lift on the south side of the river. 
 "Two Dams will be necessary, one across each channel of the river. 
 'J'otal length ot Dams, 5^16 (eet. 
 Aggregate ^\M, 406 teet. 
 Crest of Dam, 11.30 feet above low water. 
 "•The length of the next reach is iCi.ys miles, extending to the 'Rapide de I'arisien,' 
 where we have one lock of ten feet lift, on the north side of the river. 
 'J'otal length of Dam, 599 (eet. 
 Length of Spill, 445 feet. 
 Crest of Dam, 21 leet above low water. 
 " The next reach is only 2.23 miles to the ' Rapide du iUiisson,' drowning out the 
 I'etite Faucelle Rapid," so that no excavation will be necessary for the requisite depth 
 of water. At this poiht there is one lock of ten feet lift on the nortli side of the river. 
 Here the river is divided by a large island into two channels ; it will be necessary to dam 
 each of them, and also to dam the north channel of the east, in making these dams. 
 Total length of dams. 1,070 feet. 
 Aggregate .Spill, 1,055 feet. 
 
 Crest of Dam on Main Channel, 19.5 feet above low water ; Crest of Dam in 
 
 the North Channel of the Fast, 10. 8 feet above low water. 
 
 " From the head of the Lock at the ' Rapide du Ituisson', the level extends to the 
 
 foot of the Chaudiere Portage, ten and one half miles, drowning the 'Grande Faucelle,' 
 
 and ' Rapide du Fin.' A small island one hundred feet long by twenty-five feet wide, 
 
 will have to be excavated to the depth of live feet from its present surface. 
 
 " At the Chaudieie Portage there will be three Locks of ten feet lift each, the first 
 single, and the second and third combined ; located on the south side of the river. I5y 
 combining all these Locks, a saving of about $80,000 could be made. 
 " J'our Dams acioss the outlets of Ni])issing will be necessary. 
 'J'otal length ot Dams, 1,134 feet. 
 .'\ggregate Snill, 1,310 feet. 
 Crest of Dams, 16.7 feet above low water. 
 "The next or summit level extends to the foot of Lac Talon, a distance of 57.12 
 miles with a guard Lock in the Canal between Nipissing and 'I'rout I^akes, to control the 
 waters in limes of high wind. 
 
 " At the toot of J'alon Lake, there is one lock of eleven and a half feet on the north 
 side of the outlet. 
 
 Total length of Dam, 500 feet. 
 Length of Spill, 472 feet. 
 
 Crest of Dams, 23.7 feet above the low water mark. 
 " 'I'he next three I-ocks occur 0.43 miles behjw the last-mentioned Lock, and on the 
 south side of the river at Talon Chute, all in combination, each fourteen and a half feet 
 lift. 
 
 Total length of Dam, 382 feet. 
 Length of Spill, 332 feet. 
 Crest of I^am, 12.3 feet above low water. 
 '' Two combined locks of eleven feet lift each next occur at the ' Petit Paresseux 
 Rapid ' ; length of level 2.13 mites. The locks are located on the north side of the river. 
 This level drowns out several small rapids, so that but trifling excavation will be required 
 to make the necessary depth of water.

 Total length of Dams, .S72 feet. 
 
 Length of spill, 872 teet. 
 
 Crest of Dam 10.4 feet aiiove low water. 
 
 " A level of 4.62 miles extends to the " Rapide de la Rose." There we have one 
 lock thirteen feet lift on the south side of the river. This level completely drowns out 
 the " Rapide des Aiguilles," and "des Rochers." 
 
 Total length of i)am, 812 feet. 
 
 Length of spill, 81 2 feet.

 The next level of 6.29 miles reaches the last locks in this division at "Lac I'lein 
 Chants Rapide and Chute," where there are two locks in combination, of thirteen feet 
 lift each, on the north side of the river. 
 
 Total length of I )am, 664 feet. 
 
 Length of si)ill, 38S feet. 
 
 Crest ot Dam, 18.8 feet above low water. 
 
 " A short reach of 2.40 miles carries us to the mouth of the Mattawan, the eastern 
 end of the western or Nipissing division." 
 
 " The (juestion of cost will be greatly enhanced by the ditificulttes to be encountered 
 in procuring the materials necessary for the construction." 
 
 " The face coping and culvert stone for ail the Flocks west of the .Summit, will have 
 to be procurfd trom the great ^L'lnitoulin Island, in Lake Huron, which lies to the west 
 ward about fifty miles, directly facing the mouth of I'Vench River. The stone for the lock 
 at Tx's I'etites I )alles can be landed at the work, and that for the Rapide de Parisien will 
 be attended with the additional cost of two short portages. For the lock at " Du Huisson." 
 three short portages will be necessary, and for the locks at the Chaudiere Portage, two 
 short portages, and two miles of land carriage will have to be encountered. All foreign 
 materials for these locks will be subject to similar expense of Transit. 
 
 " The stone for the backing and interior of all the Locks of this division, will be 
 obtained from the excavation for locks, and from the banks adjacent to the works. 
 
 " Large ((uaniities of rectangular blocks are found upon the banks of the river, often 
 with parallel beds and joints more perfect than it would be possible to vjuarry them from 
 limestone quarries, and in size well adapted to the character of the work. The stone for 
 rubble masonry will be procured in the same manner as the backing. Loose stone for 
 filling the Dams, will be obtained from the excavation, and picked up from the river 
 banks. 
 
 " The timber for the Locks and Dams is in all cases convenient ; in no instance do 
 I think It will be necessary to haul over two miles. In some instances it will be 
 found cheai)er to cut the timber on the banks above the work, and float it down rather 
 than haul it. 
 
 " The work west of the summit requires no sjiecial descri|)tion ; there are no difficul- 
 ties tf) be encountered in the construction, of an unusual character. 
 
 " The two first miles of Canal, on the summit, between Nipissing and Trout Lakes, 
 are wholly of earth, cutting through an ojjcn marsh, easily drained. This work has oeen 
 estimated at thirty-five cents per cubic yard. 
 
 " I'rjr the remainder of the Canal, the material has been .all estimated as rock. The 
 excavation will all be disposed of with a short haulage. In this jKjrtion of the Canal 
 there are several deep ponds, which can be easily drained without machinery, as the 
 work progresses. The ro:k excavation has been estimated at two dollars per cubic yard. 
 Twenty-two hundred feet of this cut have been estimated with a width of 100 feet on the 
 bottom. 
 
 " For the excavation of the bars in Trout and Turtle Lakes, it is contem])lated to 
 commence the work at the foot of the Turtle Lake outlet, carrying it up to Turtle Lake, 
 the water of the Lake will then pass ofT through the cut. and leave the rocks to be ex- 
 cavated out of water, and easy of access. Then, by cutting through the barrier between 
 
26 
 
 Tiirile and Trout Lakes, which is only three hundred feet lon(i, the work in I'roul Lake 
 will be drained, and will he as easily acc()mi)lished as any on the whole length of the iui- 
 provenierU, e.\ce])t that in some places boats will have to be used to i)ass to and from 
 the work ; a liberal allowance has been made for such contingencies. 
 
 " 'l"he greater i)ortion of the work to be done in 'iVout lake, is the remov.il of 
 round boulders, varying in si/,e from one fourth of a cubic yard, to six and eight cubic 
 yards. 
 
 "That in Turtle Lake is the excavation of rocks and reefs, mostly in the pinnacle 
 form. ,\s they stand uj) with bold slopes and deep soundings near them, they i an be 
 readily excavated at less than the usual expense of rock excavation. .Anticipating that 
 this character of work would be looked upon as a hazardous undertaking anil expensive, 
 I have given it a price of two dollars and twenty-five cents per cubic yard ; a far larger 
 price than that for which 1 think it can be safely executed. 
 
 " For the ]>ocks at the foot of ' Lac Talon,' and ' 'I'alon f'hute,' an abundance of 
 crystalline limestone is founil at those points, and from the examination made of this 
 material, it is presumed that it will make suitable masonry for Lock walls. The excava- 
 tion for these Locks is chiefly in this kind of limestone. 
 
 " I'or Locks at ' Petite I'aresseux.' and ' Laresseux Chute,' the face stone will have 
 to be hauled alxail two mi'es from a line '^)uarry of grey granite. .\ liberal estimate has 
 been made for the ex|)ensive dressing of this character of stone. 
 
 "The face stone for the Locks at the ' Rapide d? la Ro'^e,' and at ' I'lein ( .'luuits 
 Chute,' it is proposed to obtain from the same (^)uarry."

 In the preceding pages it has been attem])ted to show that the Ottawa waters may 
 be imjiroved for vessels of one thousand tons burden, for a sum not exceeding 
 $1 2,026,35 I. 
 
 The discussion of the important questions of the present or ])rospcrtive need of 
 such im].rovement ; its effect, if constructed, on the course of Western Trade, and its 
 relative merits to other routes already existing, formed no part of my insiructiotis, aiul 
 will not be taken up here. 
 
 I shall take the liberty, however, to recommend, that whatever new work may be 
 hereafter constructed upon this line of waters, may not be of less dimensions 'ban those 
 which I have stated as necessary for the through line of navigati(jn, as the difference in 
 cost between a Canal on a small scale like those already built and such a one .is has 
 been recommended, would not amount to so much as, in my judgment, wouki warrant 
 the construction of work which might hereafter have to be enlarged. 
 
 I cannot conclude this report without exjjressing how much we have been indebted 
 to the labors of the Ceological Survey, and its accomplished director, Sir William Logan. 
 Their jjlans of French River, Lake Ni])issing, and the .Maltawan, were so complete, and 
 after a (lose test, proved so ac:curale, tliat the)' left nothing further to be desired towards 
 a genera' map of that section ot the waters. Had tlu'y not been in existence, this Re- 
 port could not have been made svithout another season's field work. 
 
 Had maps of the Ottawa River, of a similar character to those of l'"rench River, been 
 accessible, a large jiart of the expense of the Ottawa Survey might have been saved to 
 the province. 1 mention these facts both as an act of justice, and because I wish to re- 
 cord distinctly my appreciation of the (Jeographical results of the Geological Survey, in 
 regard to which my past year's labors have ijualified me to speak. 
 
 The labors of my ijredecesi;ors, Afessrs. Stewart, I'erry, and Callwey, have been 
 made use of to determine the lengths and dei)ths of the unobstructed, or rather still water 
 portions of the river, 
 
 The plans and sections of the " Rocher Fendu " Channel, and Chats Rapids, made 
 for the Department by Mr. Thomas Iv Norman, have been adopted in full. 
 
 Mr. Slater's levels and bench marks, from Fort William to the head of the Chats 
 Channel, have been followed ; everything else upon which this Report and estimate of 
 cost is based, has been derived from actual survey, carried on under my own supervision, 
 and for the correctness of which I am responsible.

 The Survey is to l)e prosccutud will) a view of ascertaining the praticahility of opening 
 a ship (:oinmunicati(jn l)elweeii the St. Lawrence and Lake Huron, througii the Ottawa 
 waters; and not for the |)urpose of making a minute and iiighly accurate hydrographic 
 <:hart of tlie river, except so fiir as the sami- may be subservient to tlie first named 
 pur|)ose. 
 
 The Lngineer in charge of eich section of tlie Survey is to examine, in tliat section, 
 the nature o( the difliculties, and liie (juantity of the canalhng rcciuired to be done, and 
 t<j stale the cost of such canaiiing ; giving in detail the dimensions and (piantities of each 
 section of work, and the structures pertaining thereto, and the prices which appear to him 
 sufficient to their execution ; in order that the data, upon whicii his estimates are based, 
 may lie open to the inspection nf this Department. 
 
 The Scale of Navigation iijion which his estimates are to be based, will be that pro- 
 posed by Mr. Shanly, /. e. . dimensions of locks 250x50x10 feet. 
 
 ('anals one hundred feet wide at bottom, deiHh ten to eleven feet. Should he, 
 l)owever, sec any reason which appears tn him sufficient for uKjdifying any of these 
 dimensions, he will make a sejjarate estimate upon such |)ortions, giving his reasons for 
 the change. 
 
 The (juality of the works proposed should not be inferior to the standard of the St. 
 Lawrence ("anals. 
 
 Me will be expected to report generally ui)on the method pro[)osed for executing 
 the works, and to designate the points from which meterials are to be obtained ; and 
 stiould any special difficulties of c(jnstruction occur on his section, he should show how 
 he proposes to overcome them. 
 
 With hi Rejjort he will furnish a seperaie plan and section of each piece of Canal, 
 carefully noting upon the sections, the difference of level between extreme high and low 
 water. 
 
 As the ([ue-stion of supp'y, upon which the success of the above project depends, is 
 to be determined upon your sect on. you will give pi.'-ticular attention to that point, and 
 to the praticahility of the plar of elevating Lake ^Jipissing to the summit level, as 
 proposed by Mr. Shanly, 'I'he (lUestion of a terminal harbor on Lake Huron should 
 receive your careful considerati( n, and the proper site for the lighthouses and i)iers 
 should be pointed out.

 Dkak SiK : — 
 
 I have the honor to submit the following Report, bringing down to the |)resent date 
 the matters treated upon in my Report of lSTx), 
 
 (Ireat changes have taken |)la(:e since that Re])ort demonstrated the feasibility of 
 im))rovmg the Ottawa and i'Vench Rivers into one ot the greatest ciiannels of commerce. 
 What was then only a scientific disc ussion has now become a matter of great importance 
 to two nations 
 
 Including together the present exports from the basin of the (Ireat Lakes, both in 
 the L'n'ted States and Canada, there is enough traftic in sight to warrant a large ex[)en- 
 diture in o|)ening a new route, if the conditions are such that the cost of transportation 
 between the Lakes and the Ocean can he diminished. Canada alone does not at ])re- 
 sent furnish enough traffic The Ottawa route must he treated as an international one. 
 
 Two remarkable changes have taken place during the last ten years, which have 
 each resulted in greatly lessening the cost of water transiwrtatton ; one, ujMjn the L akes 
 and the other between the North Atlantic i)orts of the United States. 
 
 'l"he construction of the locks at the outlet of Lake Superior has devoloped a traftic) 
 vast in si/e, and differing from all others in the world, in that it enables vessels to get 
 full cargoes in both directions during the whole season of open navigation. 
 
 The U. S. lake ports will all be deepened to 20 feet very soon. Steamers now 
 carry cargoes of 6,000 tons of grain and iron ore eastward to South Chicago, Cleve- 
 land and liuffalo, and take back cargoes of coal to ujjper Lake jiorts. It is a well-known 
 axiom that the larger the vessel the cheaper it can handle freight. These 6,000 ton 
 steamers have carried grain from Chicago to IJuffalo for 1 ,';;;, cts. per bushel, which is 
 less than one half ot one mill per ton-mile. Hence there has arisen a popular demand 
 for shij) canals of 20 or even 25 feet deep, from the Lakes to the Ocean. Kven if such 
 canals were built and could be used free of tolls, no such economy of transpoitation t)y 
 large steamers could take place as in the open lakes. 
 
 The rate of speed of thirteen miles an hour would be reduced to five, as in the 
 Suez Canal. Canal traffic would not give full cargoes in l)oth directions, and more 
 detention in port would be necessary than at Cleveland or Duluth where whole cargoes 
 of 6,000 tons of coal or ore have been handled by machinery in le^s than one day. 
 The large steamer is a very expensive machine, and if she were not able to make as 
 many trips per season as she now does, much of her economy would be lost. 
 
 It does Mf)t now seem possible, except at a prohibitory cost, to deepen the Ottawa 
 navigation to 20 feet, and fortunately it is not necessary. 
 
 The second change, which has resulted in lessening the cost of transportation be- 
 tween Atlantic ports, suggests the true method of improving th<' Ottawa. 
 
 Some ten years since all coal was carried between the shii^ping ports of Philadel- 
 phia and New York to other .\tlantic ports, chiefly of New luigland, in single collier 
 steamers, at a cost of $1.50 to $1.75 per ton. 
 
 Now it is carried in tows of three or four large barges drawing from 16 to 18 feet of 
 water, towed by a single powerful tug boat, This tug does not wait in port for coal to 
 be loaded or unloaded, but each tug has many barges, and she picks up her tow of full . 
 or empty barges without detention, as a locomotive does cars. In this way many trips 
 are made per season. The distance between I'hiladelpliia and l>oston and return is 
 about 800 miles, and coal is now carried for an average of 75 cents per ton, which is nine- 
 tenths of a mill per ton-mile. 
 
 This economy of transportation has increased the coal traffic to some twenty-five 
 million of tons annually, which is as great as the tonnage annually passing through the 
 Detroit River. The use of these tows of barges is fast increasing upon the Upper 
 Lakes. 
 
 All these facts have been clearly set forth by Maj. T. W. Symons, U. S. Engineer 
 Corps, in his admirable and exhaustive report to the U. S. Congress in 1897. He shews 
 that if the Erie Canal were deepened to 11 feet and grain were carried in tows of barges 
 of 15C0 tons capacity, it could be carried from Chicago to New York, including reason- 
 
60 
 
 able transhipment char|»es at Muffalo from lar^c steamers into canal boats, for less than 
 
 steamers of 20 feet draft conld carry it throu>;h the Eric ("anal if that could possibly be 
 
 deepened to over 20 feet, and steamers run continuously from (Chicago to New York. 
 In both cases tolls are not taken into account. 
 
 The estimated cost ot the 1 1 ft. canal is 50 million dollars and of the 20 ft. 200 
 millions. 
 
 The great value of the Ottawa navigation is this : Out of (^75 miles between 
 Chicago and .Montreal 591 miles is an inland or perfectly protected navigation, leaving 
 but 3S4 miles of open lake. In o|)en lake a speed of 41 j miies an hour can be made by 
 tows of barges. In the i)rotected portion an average speed often miles an hour can be 
 made. The cost of insurance by this route would be much less than by any other. 
 
 Uy the Welland and St. Lawrence route, there are gcji miles of ojien lake naviga 
 tion, and but 267 of inland or i)rotected navigation, The depth of the Welland and St. 
 Lawrence canals would limit the draft of barges to 13 '<^ ft. which is too shallow for na- 
 vigation in lakes such as Krie, subject to sudden violent storms. The rates of insur- 
 ance would be greater, and a k)nger time recpiired, owing to greater length, and slower 
 movement through the unprotected parts, would more than make u]) for the 22 days of 
 longer open navigation by the Welland route. 
 
 I recommend that the scale of the Ottawa navigation be fixed as follows: — Locks 
 300 ft. long X 45 ft. wide x 14 ft. deep, capable of passing steel barges 2S0 ft. long, 42ft. 
 beam and carrying 3,100 tons net on i^'/j ft. draft of water. 
 
 The excavated channels should be fifteen feet deep and have five times the area of 
 the vessel, with sufficient room for two vessels to pass each other, which would give a 
 width of iCio ft. on the bottom and 170 ft. at low water level. 
 
 The cost of carrying grain from one of the Lake ports, say Chicago, to Montreal by 
 the Ottawa route would be as follows : — 
 
 CAPACITY. 
 
 A tow would consist of three steel barges, each 280 x 42 x 20 feet, moulded depth, 
 carrying, on i3;{' feet draft, 3,100 net tons. These would be towed by a powerful tug 
 steamer capable of towing the barges at the rate of four and one-half miles per hour in 
 open lake, and ten miles per hour through the sheltered lakes and rivers of the O.tawa 
 navigation. The tug steamer would be capable of carrying a cargo of 1,200 tons, making 
 a total capacity of 10,500 tons.

 It is absolutely essential to the success of this project that there should be ample 
 elevator facilities at the port of Montreal, so that ocean steamers should suffers no de- 
 tention. With such an elevator of the capacity of one million bushels as lately has been 
 built by the (Ireat Noithern Railway at |juffalo,the whole cost of elevating and storage 
 should uot exceed three quarters of a cent, making the total cost i)er bushel two and one 
 (|uarter cents, which is tar below the cost by any existing route, or than can be obtained 
 on the Welland and St. I^awrence route when the canals are completed. 
 
 This extremely low cost is based on the assumption o( full cargoes going E:ist, and 
 one third full going West. 'I'he larger the amount of business done, the more nearly 
 will this be realised, and the financial success (^f the scheme would be enhanced, if the 
 Ottawa navigation could be extended upon the same scale, through Lake Champlain to 
 New \'ork, the feasibility of which the U. S. Deep Water Ways Commission are now, it 
 is believed, investigating. IJy this route the distance from ("hicago to New- York, would 
 be about 1353 miles, ot which 3.S0 miles would be open lakes, 847 miles inland navi- 
 gation, and 1 26 miles of canals. 
 
 Hy similar calculations to those above given, eight trips could be made m an open 
 season of 235 days, and the cost would be 2 cts. per bushel, to which should be added 
 the present elevator and other charges at the port of N. Y , which are very high, amount- 
 ing to 1^2 cts. per bushel, or a total of 3)^ cents per bushel. Maj. Symons estimates 
 that when the Erie canal is deepened to nine feet and the locks lenghtened, wheat can 
 be carried from Cliicago to N. Y., for 3.67 cts., to which add N. Y., terminal charge, 
 1.50 cts., a total of 5.17 cts ; showing the superiority of the Ottawa route. 
 
 The cost of interest, maintenance and repairs, lock tending, electric lighting, etc., 
 on the Ottawa route, would be borne by moderate tolls, and leases of water power, des- 
 cribed hereafter. 
 
 As com|)ared with the estimated cost of the Ottawa navigation in i860, there will be 
 an increase of ([uantities and a diminution of cost in item prices. 
 
 The increase of the size of the locks from 250 x 45 x 12 to 300 x 45 x 14, will in- 
 crease quantities. Also the enlargement of the prism of the excavated canal from 146 x 
 13 to 160 X 15, will increase quantities. 
 
 The locks at Grenville and Carillon, will have to be enlarged, The Lachine locks 
 will also have to be lengthened unless it is decided not to use the present crowded 
 Lachine Canal, and improve one of the branches of the Ottawa north of the Island of 
 Montreal. 
 
Another increase of cost is due to tiie fact that Lake Ni[)issinL; cannot now l)e 
 raised by damming its outlets, as was proposed in i860. 
 
 The .-country around the summit lakes is now well settled and has many cultivated 
 farms, The town of North Bay, which would have to he moved back to prevent over- 
 flow, as some 2500 inhabitants. Thirty miles of the Canadian Pacific Railway would 
 have to be moved or raised. 
 
 The level of Lake Nipissing must still lie maintained from French River to the 
 Mattawan, 57 miles. This means lowering the level of Trout and Turtle Lakes to coin- 
 cide with tiiat of Nipissmg, which can be done. 'I'nis is the only way in which suffi- 
 cient water for lockages can be obtained. The total lockage will be reduced from 715 
 to 682 feet. 
 
 The amount of excavation will be increased, but it is believed that the extra cost of 
 this will not exceed what would have to be j^aid for damages if Lake Nipissing were 
 raised. 
 
 The i)lan of i860, which raised existing levels by dams on the French and Matawan 
 Rivers and on the Ottawa as far east as Chats Lake, can still be followed, as the shores 
 are steep and rocky, and but little land will be overflowed There are a few places 
 where sites of locks and dams may have to be changed, but not at an increased cost. 
 
 In i860 the whole Upper Ottawa was a wilderness. All materials and supjilies 
 above Deep River must then have been transported partly by teams and \iirt\y in 
 batteaux towed by horses, or poled by men. Now, the Canadian Pacific Railway can 
 deliver materials, supj^lies and men all along the route, and at far less cost. 
 
 Several locks of low lift cc n now be concentrated into one, as in accordance with 
 the best modern practice. This will reduce cost. 
 
 I am in favour of locating locks so that a duplicate lock can be built hereafter 
 alongside of the one first to be built. 
 
 I now advise constructing the locks of concrete (made from the stone near by) and 
 Portland cement. The lock walls can be protected by waling pieces of steel and oak, 
 thus saving much costly cut stone masonry. 
 
 The most important item of economy comes from the fact that the cost of the rock 
 excavation, which is the largest item of cost, can be gready reduced by the improve- 
 ments which have been made during the past few years in the use of ])ower drills, high 
 explosives, and better kinds of machinery for handling materials. 
 
 The air compressors and other machinery can in many cases be driven by electric 
 power derived from the river. The latest price paid for rock excavation on the Chicago 
 Drainage Canal was 590. per cubic yard, while the average price estimated for the Ottawa 
 improvements in i860 was generally from .$1.50 to $2.00 per yard. 
 
 I am not now prepared to revise the figures of cost made in i860, as this cannot be 
 done without further examinations and surveys, which will take several months to 
 properly carry out. 
 
 There are several very important economies in construction that can now be made 
 available, which could not in i860. 
 
 It is proper to point out that the most important change in the situation since i860 
 has come from the development of electrical transmission of power. The dams which 
 were designed by me in i860 were then, and are now, absolutely necessary to give suffi- 
 cient depth for navigation. These dams will also be the means of developing and con- 
 trolling water power for electric appliances. 
 
 I can state unreservedly that I know of no other jjlace in any manufacturing 
 country, Niagara Falls not excepted, where there is such an amout of water power as 
 this scheme can make available, both for manufacturing purposes and possibly for mov- 
 ing vessels rapidly through the locks. 
 
 It is proposed to construct 20 dams on the Ottawa with an average of 20 feet fall 
 each. The low water discharge of the Ottawa never falls below 1,500,000 cubic feet 
 per minute, of which one third should be allowed to run over the crests of the dams to

 All this can be made available, by the comparatively small expenditure necessarv 
 for flumes and the foundations of penstocks and turbines. The cost of the instalhtTon
