Lonjrue tolnte. Bouchervllle. Varennes. Louerueuli, 8t. Lambert, La- P"'™, Verdun and other plaaes in the vicinity. The information oStamed from tne last mentioned sources was very meatrre. as no continuous system of observations appear to have been in any cast) attempted, and treneraily it may be said that the want ot reliable data on this important subject is somewhat lemarkable. As miirht be ex- ^^\^i wide dlflferences of opinion were elicited as to the causes of, and the remedies for, the Hooding of tbe city of Montreal it belnjf Kenerairy conceded that the con- dltlona producing these Inundations vary from year to year. ' On two points, however, all agree, that the removal of obstructions now existinff be- tween the Victoria bridge and the Bouoher- Tille islands, on both sides of St. Helen's Island, and tne geneitU widening and ktraurhtening of the deep water onannel of the river, are both calculated largely to diminish the liability to Inundation, aswell as to mitigate Its extent, under all circum- stances. Aa a result of their present enquiry, your Committee have, therefore, no difficulty In reaching a reoommendaticn. to the effect that a careful survey of the bed ot the river P«tween the points mentioned, be at once iMUtuted, and they suggest the obvious advantage which would be derived by secur- ing the co-ooeratlon of the Harbor CJommls- elonera, who aimady possess the beat exist- ing data and bare aJso the requisite staflT and appUanoea for Immediate work. Their ohief engineer, Mr. Kennedy, estimated that such a survey could be made for a very moderate sum, and oompleted lo a few weeks. Your Committee therefore recommend to the Council thegrantintT of an appropriation of say $500, for this purpose, that being the amount which Mr. Kennedy estimates tl would cost The evidence adduced before the Com- mittee, comprising statements made by Jlessrs.

I may nny I aKH>o In tho main wUh tbe opinions of thoe" (rentlemcn contalnoil In the Witneas, whicli appeared In the first article ou this subject, but think too much streea was laid upon the frazil as belna such a factor in caus- ing the dama My expoiiouce of run- ning water has led me to the conclu- sion that it requires fiomothlnjr soildoi than frazil to block a mi«:bty stream like the St Lawrence. I believe It is the solid masses of Ice alone we have to deal wlih, and not with the fraziL lean understand after the dam Is formed how the Hraaller pieces help to complete thu work, but tho small pieces would never form a dam, and If the larger pieoes could be chopped up fine, there would oe no ;thoned in this opinion from what came under my observa- tion and knowledge durlug the last hitjh Spring floods some ten years ago. The ice hero— at Longueuil— was solid. The weather having been cold, it showed no signs of breaking up, but a diCferent state of things prevailed ur) West and South: they bad had warm thawy weather, causing sudden freshets and the br(>aking up of the rivers flowing into the St. Lawrence. Conseqaently the ice came down in solid masses, and finding the ice here unyielding, went under- neath, douDtless grounded, and caused the flood. (While looking at the flood, a man from Beauhamoia told me the loe had all comedown from the rivers and lakes above the night before.) Now had there been another bridge, the ice coming In contact with this second set of abut- ments would have been broken up Into such small pieces that, though being drawn un- derneath the suiid loe, could not have caused a dam, and Montreal on that occasion would certainly have escapod a most disastrous flood. This bridge should be located just below the Victoria, where It would In no way Inter- fere wUh navigation. The other advantages to be derived apart from this, botb to the wity and country from s second bridge, are too well known to dwell upon at this tttn«. I have already pointed them out In the press. Any money expended In this way would not he thrown away, but would bring in a goo<' a perfect remedy for tho evil wo are diic-ushlnir, but it would greatly ameiio- rate it ly lessttnlng the frequency of tbe tloodings.

The current rushes toward It at the rate of twenty miles an hour carrying the ice a'^iiiust it. Driven therefrom it la forced outliuto tbe channel, carried to He iioude and Jams there. MolTatt'a Island removed and the space deepened sav to six teet, the ice would l)e carried against tbe upoer end of iSt. Helen's Island and the north aide of the river behind the Uland, thus disposing of tho creater portion of the lake ico wheq It arrives. 2. llemove the shoals which exist from tho upper to the lower part ot St. Helen's Island, deepening tho space to at least ten feet, thus leaving a wider channel foiwthe Ice to pasn down. 3. Uemove He Ronde entirely, deepening tbe space to exient of eighteen feet, con- tinuing tbe ean.e throughout the length of the bay of Longueuil. tbus providiug a channel deep enough and broad enough for tho free passage of the ice, thus freeing the city from Inundation. 4. Should a jam occur at the BouohorvlUe Islands, remove the small Island on the south side of the river, and deepen the space to 18 feet. Had Montreal been inhabited by Ameri- cans, St Helen's Island would have been re- moved flity years ago, had it catuted the flooding ot the city. A disgraceful apathy has always existed in lower Canada, whilst Ontario goes on leaving us a century behind. Tbe remedies proposed could, by proper management, be effected by the employ- ment of the many able bodied men, who are too lazy to work. These are to be found in hundreds, in the Oaoi and House of In- dustry. The sand and stone removed from the river could be disposed ot for building pur- poses, and for repairing the roods. Tbe roads in Spain are repaired b convicts, guarded by soldiers. John O. Dinnino. • MoNTBBAL, 29tb March. 1884. Note.— The above is a synopsis of tbe nine letters pubUshed in Thb Stab. J. U.

Such then beinj^ tho cause of our Hoods they puffhr, to prevent the production of auclior ice. Ho satrl there was a great deal of misap- f>reh<)nalonooneerniQ« anchor Ice, and how t U formed. He had seen a lotler in tho Chuette turowiujr ridicule upon the stato- niPut that therocnuld bo anchor Ico. Ill answer ton question about tho wideiilnff and (loe.wnluK of the channel holow tho city a*, a iireveiiilve, Mr. Galbraith expressed the belief that overy effort iu that direction would h(» of sorviee; but the ilifllculty of srettinflftt fiulHeient fall of water below tho pity would render those efforts compara- tively valueles-i. The person who wrote that arliclo In the Qazette could not have been long a resloent of this country, or he would have known better. Anchor ice formed mostly in tho Lachine rapids and In the waters above them, where the water was open, and appearr -riora like cart-loads of 8luil«re than solid ,'■■. He bad seen lar«e cakes oi lee rke from ;h'i bottom of tho water. It only formed when the tem- perature was about 10 or 15 dogrwa below zero, and where there was a roekv bottom : it would not form on wood or mud. Anchor Ice and frazil were entirely differ- ent; anchor Ice formed at the bottom and fruzd in the body of the water; frazil is anchor ice, or rather ice In its inception form, but haviuur failed to attach itself to a conductor by tlie rapidity of the water mo- tion; snow falling into the water and beiuir j()ne(-aled under different conditions, then ice Will sink in the water and add to the frazil floatin;^ there, and help to produce the ob- struction complained of. He attributed the lormatiou of anchor ico to the water on the top becoming cold and fallinsr to the bottom, where, if It met with some srood conductor whieh would carry off its latent heat, it froze Bolld and only reappeared at the return of miltl weal her, wheo it was liber.-jr^d and eim 1 to tho surface. The reason why there was so much anchor i'e In the St. Lawrence, he bplieved to bo on account, ot t'lo vast ex- teiJt of onen water iu and for ten miles above the i^achine rapids, affording sufficiout time to eff 'ct a process of euualizatlon of tomnera- ture down to the freezing point before reaoh- Ing the cover below tho rapids and thus bo- comlnar fastened to tho rocky bottom, belna hol|>ed much bv thouKltatlou of tho rapidt Inbocoininjf Btlll moro llrraly rooted thore- bv.

For purposes of uaviiratlon, the cunti e space in iiilii-ohannel (-ouidbi male wide euoutfh for steamers to pet thiou«h with safety. Tho barrier thus formed would keep tho upper ice sutllclently long in thoSprln;^ of tho year to give time for the 'CO in front of tho cit y to undert^o coobldor- ableUquofacilon and loss capable of redst- inar the upper ice wheu Itahould come down: and In this way would save us from the apnn^' lloo 1 also. Lachine would suffer no ineouvonlenco by it, but on the contrary would bo greatly bouedtod by tho ico brid;re CO formed. Mr. Galbralth said also that tho waUv is- suiujr from under this propose ; cover, would reta n a large porllou of its natural huat and would reach the cover below tho rapl Is without havinsr parted with it, to that degree nee ossary to produce anchor ice, except in extremely cold weather, aay 35 degrees bo- low zero. Mr. Baker said ho agreed with Mr. Qal- braith that whore there is a cjvi-i la^to pro- vent radiation, nothing will freeze under- neath. Thus, anchor ice would not form umler surface ice. The 81. Lawrence was one of tho greatest factories of anchor ice in the world, owing to the open wat^r at the Lachine ranlds and Lalie St. Louis. Mr. Galbralth continued to say, that if the water below aad above our city wore leas rapid and turbuleut, so that a higher degree of temperature would sufflco in effecting its close, the difflculty would not bo so great. Ihe most dilfloult thing was to start the formation of tiie ice for tho covering, and this was tho benefit of the boom. It would also serve to retain the upper ice until that below the city had a chance to break up. John Oalbbaiih. Kvidanoe of Bfr. Joel O. Baker. THK PBINOIPAL OBSTBUCTION AT BOUOHEB- TILLEL Mr. J. C.

Tbo Qrst took placn In January, 1800, the fleoond In April, 1802. the third In 1866. the fourth m 1808, the flitb in 1870. the sixth in 1872. SiQco that yoar we have had no «rrnat Inundation ; tlio water rose occasionally, but DO Jam snoiua to have formed, and tbe water oaused little damage. The grreaiest Inundation took plaoe from tbe 2:)rd to the 25tb ot April, 186*2, and the water rose at least 20 inches hUher than at any prnvioua time. In t he niotith of Deoomber. 1883, and In January of that Winter, the water rose a little, but a Jam bavinir formed near Lonsuo Pointe, the water subsided here, and when the water was very high at Montreal It was relatively low here. CAUSE OF INUNDAnONB AT BOUORBBYHiLE. The Inundations at Boucherrille are oaused bvtbo oilint; upof Ice on the lower portion of tbo islaud of Vurennos, and the oattures of the Poinio-aux-Trembles. This Is demon- strated by the HireuKtb ot the current which there throws Itself Into that part of the river to tbe South of the Islauds of Boucher- vllle and which I will call the BouohervlUa river. On the 23rd of April, 1862, the water rushed on with such force towai'ds the Bouoh(>rville river that oaooes couM hardly bo used; the same thlni; happened in 1U72, Tbe bcUture situated in the Uouchervllle river, on the lower portion of the lie St. Joseph, caused a small jam in 1870, and a commencement of the same last Autumn. OACSE OF INDNDATIONS AT MONTBBAL. The inundations at Alontreal are caused by the pllluLT up of the ice iu the batturfB ot Longue Poiuto and tbe Islands of Lonffueull. I win romark thai the parish of BouoberviUe ends at the Molson chaunel, and that the islands sit uiitod blfifber up than this ohannel are in Loujjueuil parish. The river forms at this place a cul-de-sac which has no outlet but tbe ship channel near Loutfue Pointe. It was not enouflrh, it appears, that this vicious conformation of the river caused damaite to Montreal; the Harbor Commissioners bad the earth removed by the dredflre dumped all along: the Lon^ueuil Islands, so as to torm a batture and almost block the Bouch- erville river at Its mouth. All the rubbiuu from the holds of vessels cominor into port and the sweepinf^rs of the port were thrown into the same place last Summer, poisoning the Bouoherville river. Several complaints were made and with very little results. . Anotber fact to show how little oare was tak«n afftlut ototruoUdfr the rlrer. Durioff tbe Hummer of 1889, tbe Oovnrnmont had the channel deepened between lJiiuch«rvlllo and Lonjrue Pointe. Tbe earth was thrown on each side of the channel. I do not know if it was thus thrown throughout tbe wholo lenirth ot tbe i!ut, but iu several places it la exposed at low water. Irnaiflrin a shoal about thirteen arpeuts long almost across the width of the river. Last Hummer the ferryboat get aground during a storm; it had lust be. got afloat when It ngala struck on the butttM formed by t ho dredges. When we examine this year's Jam, we sea that it is very cIoho to this bar. 'ihe dredges which exca' ated the channel in tbe batlurea of Poiote-aux- Trembles and at the head of the Hte. 'I'hen'Ho also threw the earth into the river In places dangerous lor the Ice; It was even thrown Into a pretty deep ohannel opposite the north side of the lie a Cardinal or lie & Dufaulz. This earth should always 1)0 throwu at. the end ot an Island, and nuver at tbe side. Thu Hlope ot the river between tU.> ooi* tureHol Longue PolLte and those otPolnte« aux-Tremblee being Inconsiderable, 1 am pertiuaded that a Jam formed un thu oattures ot Polnte-aux-Tremblea and the lower por- tion of the Islands of Varonnus would cnuse an inundation in Montreal if the Boucber- vllle river was olistruoted, as it Is this year. But when there is no Jam in this river the water escapes that way, and this Is what explains how It is that there has not always been an Inundation In Montreal when there was one here. THIS TEAB'S JAU. The Jam which exists to-day was caused by a sb >f Ing of the ice, composed largely of snow ice. It took place on tho 27tb of Docemtier in the night. The Ice descended St Mary's current and piled up on the batture of Longue Pointe and the Islands ot Longueull. The iiouchervllle river was blockaded be- tween the Longucutl Islands, and was free from Ice until the lower portions of He St. Joseph. This blockade was not a Jam ; it occurs at this spot nearly every Autumn. The people here called It la barrure. It con- sists of a bank ot ice too great for the entrance of the river, and which remains there. It is only a few inches thick. During the shove, a portion of this block came down the Bouonervllle river, and stupoed at the foot of the village, forming on Its passage enormous jams. At present tbe Boucbervllle river Is half blocked by Jams. The other portion of the block stopped at tbe small islands of Longueull and on the baiture lorm- ed by the Harbor Commissioners, making a Jam which extends from the property of Mr. Damase Charron on tba Island till near tba Eroperty of Mr. J. M. Browning, on the longueuil shore. A portion only of the entrance to the BoucherviUe river is free from Ice. The snow now hides a part of It, and this explains Mr. Nelson's only mentioning one Dortlon of it, that to the west of Mr. Char- rou'B farm. That part which extends to the Longueuil hill was easily visible ac the beginning of January. The ice did not move during the shove be- low the Jam on tbe Potnte-aux-Tremhles side. At this plaoe tbo ice was farmed o/ water without snow. 8 I noticed that^the snow ioe is more danirei^ oils for jamming than the sreen ice. HBAini or FBUVUNTINa CrUKDATIOMa 1 do not think there are any absolute means of rreventlnffinunaations, but some m;,y In of jrreat assistance. Those I will take the libertv to suartfest will, I think, be auvautageousto Montreal and its environs I will mention three. FiEST Means — To prevent any one what- ever trom throwing earth into the river in pluces dangerous for ice. The earth exca- vatf^a m the port should be thrown at the uupor part of the small islands ofLongueuU, and not on the west side, so as to lengthen tbo island and not to widen It. Tba earth from the bcOturea of Polnte- aus-Trembles should be dumped at the lower end of the first Islands of Varennes. _ The channel between Bouchervllle and Longue Pointe should also be examined next Bprm;r, and If the ear "^ has been dumped all alonflr the shores us it la in certain parts. It should be removed without delay. Second Means.— It would be necessnry to deepen the river on the Boacnerville side, t. e., at the two extremities of the islands of Lopuueuil and St Joseph, near the properties of Messrs. Damase Charron and G. Descham- bault. Ir a jam should occur on the battvfea or Lonsrue Pointe or Polnte-aux-Trembies, the water would escape by the Boucberviile river, which empties itself lower than the battures of Poiute-aux-Trembles. Somebody has sujrgeited excavatlnnr the oatture of Lodkuc Pointe. But let us sup- pose that the jam between the Islands and longue Pointe should be on the batiurea of Pointe-aux-Trembles, the Boucnerville being obstructed as it is now, the water could nat escape by Bouchervllle and the result would be ihe same for Montreal. Let us remark that lb would ouly be ne- cessary to deepen the two extremities of the Bouchervllle river, because elsewhere the water is daep. Third Means.— This would be principally m view of preventing Inundations In the Auiumn, those which cause the most dam- age. It would not cost much. It would consist in for alng two or three small islands, a few nundred yards of eartn dumped on t!ie lower portion of lie St. Joseph on the Bouch- ervllle side. The reason Ls this : From the first frosts of December, the river carries ice towards Boucher- yiile, , but the mouth of the river in the Islands of Longueuil being narrow, the ice Immediately piles ud? leaving the rest of the Bouchervllle river free from ice. When the Ice ascends St. Mary's current, it shoves and breaks down th's harrier, which then piles up on the islands of Longueuil and causes a Jam on that side. See what happened last Autumn. This blockade caused the jam In the Bouch- rrviiio nver. All the residents of the Islands ii'iired the descent of the blockade. This Is always a cause of trouble In the river. The small islets I should wish to see foruMMl would have the effect of stopping the first loo in the Autumn, and good ice would form on the whole Bouchervllle river iroiu the lower portion of He St. Joseph to St. Helen's Island, and this on the first iroBts. This portion of the river would be strooff enough to resist the shove, which would only be telt along the shore, as was shown by experience for several yoai's. and it would be a surety that no jam would form from the north- east portion or St Helen's Island to Varennes, on the Bouchervllle side. Let m suppose that a jam were to form on t ha bat- tures of Longue Pointe or Polnle-aux- Tremblesra third of the river at least would be free and would give passage to the water. I remember three years when the Ice had shoved opposite my property in He St. Joseph and Bouchervllle village. The shove was consideraole. and nevertheless it was only felt a little on the shores of the Bou- oherville river. When all the Bouchervllle river is covered with good ice us far as St Helen's Island, nothing will be able to break this large extent of Ice, and there will always be a free passage to allow the water to pass on the Bouchervllle side. These islets would requiro to i)e small and low, so as not to stop tne ice in the Sprlug. They should be built up on the rock men- tioned above. The river is shallow at this place. It would bo outside of the ship cbaj- ael. and would in no wise obstruct naviga- tion. The earth taken from the ship channel might be used for this purpose. THB COST OP THESE WORKS. The first means suggested would only cost the good will of the Harbour Engineer. The third means would coat little. It would be Bumcient to dump a few barge loads of earth on spots selected beforehand. Lastly, the second means, the excavation of the entrance and outlet of the Boucher- vllle river, would cost something, it Is true, but I do not think it would coat more than the excavation of the batture ol Longue Pointer BESUVOL I believe the inundations at Montreal and vicinity to be caused by the ice jamming on the batturea of Longue Pointe and the LonguouU islands, and on the battures ot Polnte-aux-lrembles and the first islands of Varennea These jams are caused bv the Rhovlngof the ice, which descends the St Mary's current and which is the primary cause of all the inundations. Aiid that the means of preventing them would be: Ist To prevent the obstruction of the bed of the river by the earth excavated by the dredges: 2nd. To deepen the two extremities of the Bouoherville river; 3rd. Tpforni twopr three small islets be- tween He St Joseph and the lower porUon of the parish of J3ouchervUle.

JBIiAHINO THK OLBBK OF THE WEATHSB. Alderman Mount said he desired to ox- plaluhU thuorvot the iuundatioa of 1884. For about t'ourtoun years ho hud bnen living; at the fool of the current, and was in a posi- tion to notice tbe phenomena utlendintf the liver Hood". He considered that tiie inun- dation hiui beiin caused by the manner in which the ioo ha'l formed this Winter, which was quite diff.-rout from other years. This Winter tae ico tjjk first early in December, then eii-'ht or ton tiays thaw ensued, wheu It was sometimes above and so.netime^ below freezluqr poiiit. The ice then sboved down ae far as Loiijjuo Pointe on to tho shoaU.and remained.untii it tool; u second time. Dur- ing the mild weather, bowovor, the snow or frazil pacUtjii and for;ned a barrier, which, he couTiiderod was tho cause ot the iuuuda- tlou. About tho 4th or 5tb of January tbere was severe weather asain,but tbe ice was* not sulllcioiitly strouar to break up tbe b , f the cit v newerage. it be- ing un accepLed fuct tbac tho rise of water in the harbor was caused by lee obstructljus oppo-^ite or below the city, i conllnud my obsorvailons to this sice ot the river, and between Victoria iJridgtt and Lungue Pointe. The only records which I found avaiftible were : Ist. A report of tbe lioyal Engineers in 1841. on tbe poriodical floodiug of Mont* real. lind. Tho gauging of tbo water on Lock Sill at the euiranco of tho Lacbine canal. 3rd. Levols taUeu troiu Jacques Cartier Square to Haiidysid;^ Crock, on the previous April, by Mr. Joseph Smith, who was at that time Deputy City biuveyor. I also saw several persoQS wlios^j uamca were given mo by Mr. Maequutou as being ukely to have made usulul observatious ou tbo subject. The report of the Royal Eugiuoors shows that these Hoods always existed, more or less, during January and April, and that their frequency and o.-itent is leas now than formerly. Plans also must have accompanied this report, but I found uo traces of them; tbey would be of littio service, as owiug to the changes In tho city since tbey were made their designs would be impracticable ut the present date. Tbe daily record of the height of water at tbe entrance of the Lacbine Caual allbrds no meaus of Uelermining whether tho height ot water recorded was cau^:ied bv tbe loo grounding opposite that portion of the city or lower down the river. Tto levels taken by Mr. Smith in 1869, ex- tending from Jacques Cartier square to Longue Pointe, permits a protllo ol tbe sur- face of tbe river during flood to bo made be- tween those points, and was the (mly avaii- kble record up to that date which showed the relative height of the river during flood ; they give a fail or 4.33 between lluiaseau Migeonand Uandyside Creek, and clearly show that a large jam ot ice existed be- tween those points. The flood water in the harbor was unusually high tbat Spring, being two feet above tho revetment wall at Jacques Cartier square. 1 took a series ot levels during tho Winter of 1870; they are sbown ou tho accompany- ing diagram. The flrst was taken on Janu- ary lltb, when tbe water was at its highest point during that season, being one toot below the revetment wall, with a fall from thence to Longueuil terry of 4.30; and from theuce to Longue Pointe Church ot 8.30. After re- maining a tew days at about that elevation the water went down, and ihe next rise took place in April. An examiaai ion of the weompanying diagram siiows that a oon- sMeiable change in tne proportion of fall at tho points of oljservation, botwoen Jacques Cartier Squaro and Lou^'uo Poiute, took place; and that during tao iulervol between January aud April, oosttuciions had formed on the sboals iu the neighbor- hood of Longiio Poiiito and from tbenoe upwards. It also shows that t:i(.< grouudin-' of tne ice ou these lower sboals raised the water there several tout iu beigbt without causing a correspourling rise ol wat 'r op- posite the city, for on the 10th of April tbo water was withiu two luet ot the tup ot the I'ovotmcnt wail and romaiaod at the same height ut that placj until the 12tii U >ring this interval of time great quauti- tiea of drift ico came down from Lapialrle Basin, aud by cboklug tlie channel raised tne water about two feet, betwoeu lioche- laga and Longuo Poiuie, wituout making any change in its height opposite Jacques Cartier Wharf. 10 From levels taken durlnnr thli Winter It appears that the fall of the water between Jacques Cartier Square and Lout^ueuil Ferry varies from 2' .00 to 2'.4. If the rise of water opposite the city was caused by the acGuiuulatioDs of Ico on the shoals lower down the river, it would be shown by a correspondlD« reduction *f the fall between tlieso points, pr iu othor vrords tlie rapid would bo drowned out; but the diagram shows tiiatsuch is uot the case, because when the water is at its biurbuut opposite Jacques Cartier Square there is an increased tall from thence to Longueuil Ferry. I took corresponding levels m the succeed- ing year, 1871, they are recorded on the dia>rram in a siraillar mauner to those taken in 1870 and coutirm the oonulusious arrived at trom the levels taken the previous year. The diagram submitted by the City Surveyor, Mr. St. George, shows In dilTereat oolors,the flood lines in 1869, 1870, 1871. 1883 and 1884; the January floods nro shown by a firm line, and thu April floods by a ilutted line. In every case these Hues show that the height of the water between ilocholaga and Louf^ue Poiute is raised in tho Spring by the accumulatiDn ol ice between these points; without causing a corie*pondmgr rise of water oD0o-*ite the city. This is very niarlsed iu the flood linos of 1870 and 1871. Althoush I found no record of in^itruiuent- al levels taken previous to 1869, tho evidence of residents on the rlvtr bank aemonstrnted that in some oases an extensive dam hod formed below Boucherviilecauslng the village to be fl^x >('.e;i. Tho leveU taken in 1867 clearly shot * dam formed between Buisseau Migeon and Handvslde Creek, and the village of Lou- gueuil was flooded by it. The levels taken in 1870 and 1871 show tho ice grounded all along the slioals from Longue Pointe to flochelago, but no special dam was formed. This year the levels taken by Mr. Nelson, Assistant Harbor Engineer, clearly shows that the principal dam is just below Longue Pointe Church. From the above records it appears that the location of the ice dams is not uniform, and that in some cases no special dam Is formed bietween Bouchervllleand Uochelaga, although the ice always accumulates during the Winter months on the shoals between t'lieeo points, and causes the water to rise there without causing a corresponding rise of water opposite the city. The average fall of the river is less aneoted between Jacques Cartier whart anc. Loo- gueuil ferry than at any other part of the ohannel, as the depth and rapidity of the current between those points keeps it free from drift ice and frazil. If the floods od- poeite the city were caused by the dams of toe below Hochelaga, Bt Mary's current would be drowned out, but the levels taken ahows that it is not the case, and that during floods the fall of water is greater in that current than during ordiR.-jry circumstances. The evidence uniformly goes to demon- strate that tho rise of water oDPoatte the city is caused hy a dam being formed on the aboals below the Victoria Bridge on the south side of the river. The old Grand Trunk wharf, and Moffatt's Island form the nucleus of the dam. and It is rendered flolla by the drift ice and frazil. That this wharf is a serious obstruction and diverts a large quantity of water Into the nortb channel, that would otherwise pass down the south channel, there is liitle doubt At ordinary summer level tne water is from a foot to eighteen inches higher on the up side of the wharf than upon the down side, and during Winter thisbecjiues a holid dam, and almost the whole volume of water, in- creased by frazil and drift ice.Uas to pass St. Ueleu's Island by the north chaunol. That extensive ice dams occur above Moffatt's Island ana raise the water oppo- site tho entrance uf tlie Lachiue Caualis alsu ubowu by levels taKen during the last two years to locate t he position of an out- tall sewer for Point tst Ciiarles. These levels show that the fall of ttio river, from one hundred yards above Victoria Bridge to the entrance of tho Laohitie Caual is as foilow-j, viz. : When the river is at sum- mer level the (all between these points Is 8'.0. When the river is at flood level the fall between these points ir* '^'.03". Tbeso flgures show that thu natural fall of the water between these poiuts is drowned out by the uccumulaliuu of dritt ice and frazil In precisely the Haiue manner that it occurs between Longuu Poinie and Uoche- laga.

As be thought that the plan which he submitted at the last meetiuflr was not fully comprehensible, he would elve further details about ib In Lake St. Francis the ice generally broke up about fifteen days utter that at Montreal. The consequent shove caused a dam below the city, which was quite impervious. He pro- posed the construction of two rows of piers or booms, one from lie Dorval to Ht. Nicho- las, and another Just above the Lachine rapids. In reply to a question by the chair- man, be said he bad not prepared an esti- mate of the coet of such construction, but would do 80 for the next meeting. his Charles X Lbobb. mark. Witness: A.

One of tbo most important pieces of evi- dence, which he bad beard no far, was that ot Mr. De Grosbois, which did certainly re- flect much credit on that gent leman, and he agreed with him In what be bad said. MoNTBEAL, January 24, 1884. Geologists tell us that the valley ot the St. Lawrence, in tact the great ioterior of the continent, was in past agt>s a great basin which has been by lurus repeal eilly depressed and elevated, the successive stratilications at present existing therein. Doing deposited during each submergence, from material eroded from its shores and highlands. This erosion, speakiug in gen- eral terms, produced in the course of the last of these changes tbe alluvial soil whicb at this moment covers tbe vallov of tbe rlvor, and through which it has cut its pre- sent course. Beferring to the particular part of tbe river which at present demands our atten- tion, that Is between the Laoliine rapids and the toot of the Island of Montreal, you will perceive that as the river excavated its bed and shrank to within its present sbores, numerous islands came into existence. Xhese islands were foi med by the presence of obstructions which made it easier for the stream to cut its way on both sides of them than to carry them off, that is to say, the river followed what Is called the law of least resistance, according to which tbe stream first divided at the bead, and then became again united at the loot as soon as that law permitted. Here, at tbe heads ot Heroa and Nuns' Islands you can see the groups ot boulders which remain of tbe original bar- rier which produced these islands, also the small island and ledges above St Helen's, etc. Looking at the conformation ot this part of the river there can be little doubt that before the shore line took its present shape,' its main channel ran in a direction more conformable with its general sweep than it now does; thus, with Its north shore about tbe same as at present, it flowea at a comparatively even width throughout, its main body taking the south or rather east channel at Ht Helen's Island until it reached Longue Fointe, then not so defined, buC more rounded like Fointe aux Trembles, below which there appears little reason for supposing any material change. The north channel at St. Helen's Island would bo small and, very likely, at first discharged nearly all its waters through the passage between St. Helen's and He Konde. At this period all the islands now seen, and perhaos more, were in existence, and teyoud some reduc- tion in size from wearing away by tbe stream, present the same appearance to-day, except in one very notable instance to whloa I shall presently refer. As tbe river continued to cut its way, always obooelng the aottest places oonsiM* 12 ent Willi the correlaMou of its forces, it be- $taa {rraduully lo excavate here, on tbe outer eido ol iiH curve, the Laprairie buy, aud im a coueequeuce oi the cbanflre of curves so pmdULod, le„'an nUo to hollow ouc tu« Donh or wesL cUatuiul, known as ttie bt.

Tdhs Moseo that this new curva, worn alonff tne Hcchelu,,'a shore, is re&lly what has made whutwocall "Loujfue Poinle," this being the pltieo where the two currents ruuniuif 8ide by side fairly resume a united course. Now i wish to draw yonr attention to the remarkably exceptional character of one group umon^ all these islands, to which 1 have ailudtid, namely the Louchervillo Islands. It you havo attentively followed, and uilmit my reasouing so tar, 1 think you will also airroe with me in oonuidi'i'in^r that, orliriually, these iiiiands weie uiiiied as one, hawngrtho samevoa- eral oval form as all tiiS rest, aud than as the north channel began to monopoliz.t tbe volume of thi) river and lushedtoita junc- tion with tbe other off Lougue Pointo, tn > latiei' was tiitust more upon this iel.tud forming first a buy and finally a channel sepaialinflr one part from iho other. Tula channel, on account of its currenc behit; reduced In speed, would, at its lower end, separaLo into several small passages foim- iu.^ ail these sn^all islands. You see tbey all partake of the same fronerul form witb theie-'t. But this is not all. You perc.'ive that tbo main island Is traversed by several small channels or rivulets absoluieiy at rlfirht ancles with the cimrso of ibo river, divldin^r it up into pieces, luuch as a cook Would divide a lout; flsh for frying; and here I think in these apparently iubi;z'uifi- cant water ways we will find the key lor the Bolutiou of the main diiSculiy, if not of tbo whole question. Between those Islands and the south shore thorn is a narrow channel navigable to vessela of small draught, the whole lying well out of tbe line of the ' main current of the river. Now surely, it might be expected that tiiese narrow passages, and even tbe channel along the eboro, lying as tboy do in a sort of eddy, would silt up ; aud yet there is no tradition that 1 know of, of their ever having I. oen dilTerent from what they now are. Tbo names ot the islands have existed from very early times, and tbougli the passages have been long encumbered with fia=>8 and sedge tbey havejnever been closed. t is therefore to the conditions of their formation that we mu^t Iook, to explain theii preservation: and to do this wo will first look briefiyat another question, name- ly, the formation of what is called frazil ice. This question, upon which afereat deal has been BBid and written, I would like, vory much to take up at length, but at prob^eut it would take us too lar Irom our subjeet 1 will Lherelore only eay that what 1 havo every reason to believe is the trm> tho.irv, one wuicb I may be pardoned lor looking upon with some satisfaction as being my own, is this, as applied to this special looality. m very cold weather the water pnsslna down the Lachiuo Bapld^ becomes practl* tally reduced In temperature te ow freezing point, ami pass'iug beneath the slower mov- ing waters at i heir foot quicidy r<»lrigerat«8 the stones and bouMers spread ovtu' the bottopi ot the great area boluw, converting it Intoa veritable nursery for thu prodiio- tiou of frazil H'a\ TiK're is plenty of ovideuoe of i.his latter laet, which I wiil not now stay. lo give. Tbe frazil thus tornied Is cou- tiuimlly heiui; broken oft in small quantities and fioateil down, but when a sudden thaw occutv, it detaches ifsell in large masses like h'aps of gigantic icy bar.H, and floats down until it finds a place shallow enough to bold it between the under surlace of tlie ice and the bottom, where it stays nvA is packed in, and extended liy siic-cee.dlng masses, until the wa'er way is no na^r )wod as to cause a more or loss sudden rise of water. Tbe fluctuations or partial I'rills.that lollow rlyes aiK duo to the liii-akieg away ot [larts of these dams wheu lilted oy tue rltjo. Thus we may fairly assume thai frazil Ice is the immc'diate cause of the rise of the river in Winter, for it is only m tbe breaking up river by fiazil leoisot yearly oceuiTene,>, lor there is always more or less of rise, therefore it is only when the conditiims are most favorable lor the proiluctiou of ibis sub- stance that a ilood occurs. Again; so long as the normal course ot the slreani li not iulerfereJ with, tlnue will be little difference ot locality in tue deposit, but only of quantity, Oneother fact, weaie apt to lose bly^htoi, must be borne steadily in mind, tmd that U, that the volume ot the river in Winter, ex- cept in beav.v thaws, scarcely ever surpasses that of low water in Summer. This n im- portant to remember because It is this low- ness of the water which narrows the space between the surface lee and the bottom. Hence, tbe lower the waterat the beginning, the more rapid and exteubivo is the forma- tion of the dam, it all other conditions are the same. liearing all this in rain I, let us see what course the frazil ice once in ntotioii will take. The south channel being shallow and ob- structed would attract but little, and the mass would be carried by tliecurrent direct- ly down against the city, and, depositing its quota among the wharves, it would sweep along the Hochelaga shore towards Longue Pointe. A small portion would be atiract- ed by the current between Ht. Helen's Island and He Ronde, but the proportion of this would be 80 small, that the removal ot this, latter island, so strongly advocated i)ysoine, would not probably make a noticeable differ- ence. Arrived nt Longue Pointe it would shoot out a talus in tbo direction of the shoal at that olace, across tbe main chan- nel, and towards tbe opening in tbe Boiicher- vllle Islands. Immediately the river would begin to rise, in Droportion to the obsUue- tion formed, until tbo force of the current liecainoBuffleleatto break off or deflect the end of the talus and carry away I he surplus rittzll, to lodge among the Islands bebw.

And now we come to the ex- planation uf these small lateral passages which so curiously divide the Bouchervule islands. The confined water of the main channel rises coi. iderably higher than that of the narrow channel along the south sliore, and hence, in escaping beneath the ice, these little channels iiave been cut. Thus these channels are winter torn, and are not silted up in the summer because every winter they are washed out bv the same agency that originally produced them. Tltis, then, is my theory of the cause of the winter floods which aft'ect the city of Mont- real, based upon my investigations into the character of frazil ice and its effects : and I pretty confidently expect that the result of the examinations undertaken by the city and Harbor Engineers, now in progress, will confirm it in every important point. The Remedy. Assuming my theory to be correct, I would confidently recommend : Ist. Widening the ship channel at Long Point by cutting the flanking shoal entirely away, close up to the shore, and so straight- ening as well as widening the channel. 2nd. The conversion of the cul de sac in the Boucherville islands into a channel of relief, by giving an exit below. 3rd. Removing Moffat's Island and clear- ing the south channel of all large boulders and projecting rock ledges. All this would not, of course, prevent the forn.ation of frazil ice, but it will remove it to a safe distance; and, for the same reason, very largely diminish chances of ice jams in the spring if not entirely remove them. It would be as idle to attempt the entire prevention of rises in the river as to do away with the ebb and flow of tide ; but we may reasonably expect to be able to kee() these rises from becoming floods. I would add, in reference to my third re- commendation, that the exca.vation of the south channel at St. Helen's island to a depth sutticient for the river traffic in the summer, would be still more effective, and I confidently predict that this will some day be done, but unless it is made part of a more comprehensive scheme of harbor improve- ment, it is not to be recommended, since, by itself, it would have the effect of lowering the harbor level during the dry summer season, which also means a reduction of depth upon the lower still of the canal lock. Geo. H. Hemshaw, C.E. Kvldence of Mr. John Kennedy, Harbour Engineer. Mr. John Kennedy, Chief Engineer of the Harbor Commissioners, produced a num- ber of charts and maps showing accumula- tions of ice at various points in the channel, depth and width, taken at times of flood. He explained that tb« flood of last fall at Montreal was caused by a general diminu- tion of the capacity of the diannei from the Victoria Bridge to below Loiigue Points and not by an ice jam forming a itaiii at any definite point. — Levels taken during the flood show only about a foot of bucking up of the River at the large ice juui at l^oiigue Pointe, but from that to tlie iiridge tiiere was a gradual increase of the t^urfuce inclin- ation to an average of about 20 ins. per mile, as against 6 ins. per mile in dimmer. A coating of Irasil ice on the botiom an J ac- cumulations under the surface ice might easily increase the surface slope of the water, say an inch per mile, and even this little increase extended for miles would have a very marked etfect on the water level. — Add to this solid accumulations or jams ut var- ious points, still fiirther reducing the chan- nel and increasing the slope, and floods are easily accounted for at Montreal. Floods occur at many points between Cornwall and Quebec as well as at Montreal } at Cape la Roche tor instance, ihe water rises in such a way as sometimes to flood Batiscan. — Three Rivers is also Hooded every five years. Ice jams are frequent at Cornwall, and the water powers oi tlie large factories and mills there are sometimes drowned out all winter. From these lacts it may be gathered that the ice accumulates every place where a rapid current changes to a slow one, and that it otten jams in such a way as to increase the hydraulic inclina- tion more or less abruptly, and thereby causes a flood. In the case of Montreal it is well known that the ice "takes" first at the Boucherville Islands, and the river from that to Lachine is open much later. It the frost is very severe during that time floating ice and frasil are formed very fast in the open water of tlie Lachine Rapids and La- prairie Basin, and those are floated down to the stationary ice till the whole harbor is not only covered with packed ice, but im- mense quantities are carried under until the area of the channel is greatly reduced, 'i'be combined effect of the friction of the surface ice and the choking up of the channel be- neath is to increase the surface slope of the river, from about the Boucherville Islands to the City, to a greater or less extent, and in some years to such extent as to flood the lower streets. The recorded levels and careful observations are fiew and incomplete, but, so far as they go, they show that floods are due to tiiis gradual rise over a considerable distance, and nottq the ice jams u which appear so formidable upon the sur- face. In 1862, at the time of the flood, levels of the water in tlie river were taken by tlie Road Department which he tlioMglit were Btill on record in tlie Koad Department. He waH of opinion that frasii forms every- where in open water and extreipe cold wea- ther, whether the water be in rapid motion dr other wise. He is not aware of any re- medial measures yet proposed which could be relied upon to prevent floods. The dredg- ing hitherto done had made only an inxig- nincant ditch in the l)ed ot the river, as com- pared with its whole enormo.is volume. There are no local obstructions in the river at Montreal by the removal of wiiich we could hope to entirely relieve Montreal. The building of piers at the toot of lakes St Francis and St Louis might do some good, but would not affect the general question. Mr. John Kennedy, Harbour £n>ilDeer, ooattnued bia eTiilence as to ttio natui'f and extent o( tbe several iuun>latlona whiub bad ooourreil during: ttie last twenty years, au J, althou>;h not cow ui'epared to oCe^ any aug- f^eatious lor the prevention of floods in uture, was of opinion tuat tney could be at least mitigfiiled. Tho inior mation as to the Important facta and condiiioos which ac- company floods are so meaKre and frag- mentary that it would >>e unwise to base a scheme of prevention upon it. He strout^ly advocated a comprehensive series of obeervations and survey of the river from Varenaes to Lake St. Louis, for the puroosn of obtaining; full and accurate information as to all the fa-^ts accompanyintf floods. This could only L : done at considerable ex- pense, but It IS the first essential step to- wards dealing with this important question. Mr. Kennedy in reply to a question by tbe Chairman said he thought thai if the main channel about the Boucherville Islands wore widened and straiffhiened it would be better, or at least ia the right direction. He could not say what this would cost without further surveys. The probable cost of mak- ing the surveys between the city and tbe boucherville Islands would be about ioiM, after which the cost of widening and deepen- ing the channel could be very easily deter- mined. Mr. Cramp asked how long it would take to make a survey; to which Mr. Kennedy replied that in Summer a survey could be made in about a month's time. In reply to a question by Mr. Jones. Mr. Eennedy said some of the pieces of ice which pass through the harbour are very larse and some very small. Some of tbe pieces were so large that it was puzzling to know how they could pass under the Vic- toria Bridge. He did not think that the construction of another bridge would do any real good towards proteotln* the city from floods. JoHM Kennedy. MoKTRBAL, 3rd April, 1884. To the Chairman of the Flood Committee, Dbak Sib :— I desire to record the follow- ing remarks in reply to the opinions express- ed bv the Harbor Engineer at your meeting on Tue^ay last, which the lateness of the hour prevented my making on vhat occasion. It is neither reaVonatile to expect, nor to be desired, that Mr. Keniiet'^, occupying as he does soimportaiitanotHcial position in rela- tion to the siiliject, should be other than ex- tremely cautious in eitlnr adopting or con- demning views which firther invedtigaiion may, or may not, prove o be erroneous or in- adequate. 1 therefore take his remarks to be rather the exprc. sions r f his present impres- sions than the tc»u'.* ofsettleil conviction. I entirely agree with him as to the actual facts presented by him. There can be no question that the river is high from one end to the other, and that floods take place at other pointi beside Montreal, but ihe pre- sent question does not concern them ; neither is there any doubt as to the very slight win- ter variations in the hydraulic slope of the river, observed during floods; but this fact, taken only by itself, constitutes no agree- ment, or rather might reduce it to the ab- surd alternative, that there either could never be a flood, or that there mu-'t always be a flood. Of course Mr. Kennedy does not mtan this, and I mention it only for the benefit of those not well acquainted with technicalities. If, however, it is his opinion that tlie whole river would have to be treat- ed in order to remove floods from Montreal, then I cannot agree with him. The hydrau- lic slope of the river is composed of many various slopes, due each to the nature of the obstructions encountered, and is an average of all. I hold it, therefore, quite possible to materially alter the slope at one spot, with- out at all affecting the general hydraulic slope of the whole. In fact it is a natural alteration of this kind, though in an opposite direction to that desired, that has caused the flood. Again, no doubt, in summer the ship channel, as Mr. Kennedy says, is but a scratch in the bed of the St Lawrence, but to my mind in winter its relative importance is vastly increased, since, judging from the few cross-sections taken, it, together with one or more of the natural channels, consti- tutes at certain places the sole outlet for the volume of the river, and consequently has to make up in heiglit what it lacks in width ; unless, therefore, it can be shown that there is no larger area below the obstruction than at it, I can see no valid reason against en- larging theopening at the obstruction. What- ever possible difference there may t)e between Mr. Kennedy's opinions and mine, I think at least he will agree with me in this s that, considering the statements made as to the coincidence of floods with certain dams of ice, by Mr. Orosbois and others, the public will be scarcely satisfied until such exam- inations are made as will prove or disprove their agency in causing floods in the city. jeer at your meeting li the lateneHH of the ing on .hat occasion. le to expect, nor to be K'y, occiipyiiig as he icial poHiiion in rela- Id be otl)er than ex- nr adopting or con- farther investigation o be erroneous or in- ke hiR remarks to be f his pre-ent imprea- settled conviction, iiiin as to the actual I.

Hail the late unusual thaw of ten days and nights been ex- tended a tiew days longer, a movement of the ice of a very dangerous cliaracter must have taken place. This has, however, happily been averted until the ice has b-^ome so rotten as no longer to be capable of adhesion in large masses ; but the lesson it tenches is certainly not to told our hands with the Turk, and cry Kismet, it is fate. I remain, dear Sir, Your very obedient servant, Geo. H. Hbkshaw. Mr. Louis St Denis of the City of Montreal testified as follows : I am a pilot and am well acc[uainted with the St Lawrence and Ottawa rivers. I would recommend, in order to prevent future inundation, that piers should be built across the Chateauguay shore from the south to the north channel, so as to re- tain the ice there and keep it from choking the river lower down. The piers could be ^built on the shoals where the water is not more than three feet in some places and a little more in other places. A part of the work can be done this winter. For further reference I would refer you to my plan. I am well recom- mended by several Marine Inspectors. Louis S. Denis. Evidence of Mr. J. M. Nelson. Asilatant Harbor Kngloeer, DYNABIITB CSELESS. Mr. J. U. Nelson stated that there was ^ dia^ereace of only four inches in the level oi the water between Lonurueuil and Huobe- la^a on the 3rd January last. Between Montreal and the 1 >" point there was a fall of three feet f^c . inches, which was a little more than normal, the fall in Suca- mer being two feet three Inob^s, The south cbaanul was noas ly blocked up this year, there boin^ no current to speak of and thd water \r&i turced round ot.

If the daui was blown up it could jam lower down. J. M. Mklsom. Plantaoekut Sprikob, Ont., April 27th, 18S6. To His Worship the Mayor, the Alderinm and the Oilixetus oj Montreal. Gentlkhen, — I herewith address to you a paper written by me on the important sub- ject of the flooding of tUe city of Montreal and Its environs. Were it not for the loss of my flood notes, reports, &o., which I had kept for many year{',and which were being in use by the late City Surveyor,! might have made this paperoi more value as to precise details. As It is, I have thrown together some par- ticulars and explanations from memory. I have added thereto such remarks, opinions and suggestions as, in my humble opinion, the importance of the subject merits. Had I remained in the council it would have been my duty to make use of the pre- paration made for it. If 1 have failed to afford sutficient explan- ation on any part of the subject which it may be in my power to extend, it is only necessary to call on me to do so. I am, gentlemen, Yours very respectfully, Wh. Uoddbk. ICE SHOVES AND MONTREAL FLOODS. This subject is now and has been one of the most important before the City of Montreal, It is a subject that has received much atten- tion during the last half century. The loss and damage suffered by the people diiring that time must have exceeded tue amount it would have cost tj have placed the streets that are below high water mark, sufficiently high to enable the people to use them without interruption, and assist in furnishing a partial remedy. Many years ago the corporation fixed upon a higher level for flooded streets, and have done much, particularly in St. Ann's ward, to raise them, some parts of which have re- ceived as much as four to eight,ten and twelve feet offlUing. It is true there remains much to be done to finish that part of the required work, and it should be very well understood that raising the streets is not all that is needed to save citizens from periodical flooding of their premises. I'he people naturally look to their repre- sentatives in council to consider and adopt measures of relief, and also should look to their representatives in Parliament to con- sider whettier or not the causes are outside of the bouadariesof the municipality of Mon- treal, and they should come to the assistance of the city corporation in obtaining the per- formance of what is needed to be done on the river and harbor works outside of the limits of the city's control* and obtain legislatiofi for II il the corporation, aivinf} powers to do their part ot tlie work without liabiliiv for damages. Tlie great etforts made to keep down taxes, the desire of tnenibera repre- Heating other 8ectiorii< of the oity to obtain all tliey can from the city treasury to im- prove their sectionH, have often made it difficult to obtain suitable expenditures on tlie flooded section of the city, whiich are the outleis for tlie trade of the city to ite harbor, the canul, and railway stations. It would be out of place for me here to give particulars of the persistent efforts of mem bers of council re- preaeiitiiig tlie Hooded sections to secure a full share of uUention, nor is it necessary I should speak of what was done in my time of mem- bersuip— the work done speaks for itself j if more was not acconipliMiied it was due to the magnitude of the required work, the im- possibility of reconciling tlie different opin- lons^on the causes of flocwing, to justify enter- ing upon a lull and perfect system of relief, and tJie difhc liy oi bringing together all the interests outside of the city limits, that, sooner or later, must participate in the ex- pense of the necessary work and its benefits. I can well understand tha difficulties of the position of an alderman, particularly if he had much business of his own to look after, while he is at work on extensive and troublesome municipal questions, and if at ail zealous in the performance of public duties, his own interests are damagedjunless he is more fortunate than is usual in having about him thoroughly reliable persons. Then, again, an alderman is surrounded by a multiplicity of persons interested in smaller questions turning up f'om day today, press- ed upon him by electori.each often unwilling to look at any subject excepting as it trou- bles or beuetits himself. Tlius tlie aldermen are subject to great trials.hindered often from full study of great questions, and eventually either become disgusted wita the humiliating position, and retire, or take an independent stand in what they consider right, and have all sorts of unjust motives heaped upon them till they feel it impossible longer to continue the connection, and leave tne work they were engaged in to be longer delayed or to fall into the hands of persons unwilling or unable to give.the necessary time and study to the task. Feeling, as I do, the full force of the fore- going expressions, 1 have no diHicTilty in understanding how that the death or re- moval of a civic officer and the retiring of aldermeu who labored on such important questions may to some extent account for delays, particularly when it is considered bh»t the great majority of the council repre- sent other sections of the city claiming their attention. These considerations have led me to the conclusion that the city council might aptwint a commission, with the mayor and chairman of finance e.vofficio members, who. with the assistance of a first class engineer of experience in this country ,acquainted with the action of the ice and the doods, could take all necessary means to consider, report upon, and eventually carry out whatever work the city council might determine to be necessary to be performed within their juris- diction.

On one of those occasions of general floods the roar and crashing of descending ice, brought out St. Paul street merchants to view the immense fields of ice evidently from the upper lakes, rsing down below the city. Piles could seen as far as the eye could discern, evidently grounded on shoals as far as Boucherville or beyond it. I remember well tlie cluster of merchant neighbor* viewing the magniticent but terri- ble crushing and piling tields of ice, while the? laughed at the idea of 90 to 100 thousand dollars being of much servjcer and asked one another how many millions of dollars would it take to afford permanei»t relief. There stood within my hearing such men as the late John Torrance, John Frothingham, Jacob Dewitt, Horatio Gates, Wm. Lyman, Esquires, and otiiers, ihen as well-known. In St. Paul Street many stores and shop floors were again flooded, and many goods damaged. I continued to follow enquiry into the periodical cause and effect of such magnificent yet dangerous spectacles, and I gave attention to the remetfies suggested. Those great floods were not confined to Montreal. The changing features of ice jams and floods has beei. such that, within the twelve months, notes have been taken of shoves and floods that at intervals operated upon every low-lying section of country from Sorel to Beauharnois, extending thence across the lake to Isle Perrot and St Ann's. Such extensive floods as the one here re- ferred to were preceded by low waters in the river during the time the ice formed that fall and winter. The early part of the winter was very cold, accompanied by very light snow falls, and the ice on rivers ana lakes formed very thick. In the early part of March mild weather and rain converted the snow on the ice into water, and weakened the ice much more on the upper lakes than upon Lake St. Louis and the harbor ; some ice from above that lake came down to the shoals near Beauharnois, causing higher water above. Frost set in on the third night of the thaw, the following morning travelling on the river to Beauharnois from Point Claire was resumed, and I spent that day on the roadjalong the river through Lower Lachine, Point Claire, to Isle Perrot, thence across through Beauharnois to 8t.Timothe,and back to the city, doing 75 miles, and as I passed along I viewed each point of interest, which produced a conviction in my mind that, the spring flood would be serious and w' ■ - spread, inasmuch as the ice from Beai nois down was very strong, while that on tue lakes above was reported to be much B damaged by the thaw, and likely to come down earlier than usual. The shoals in the narrows above 8i Ann's lock wei-e cov«re 1 by ice jams, the water above was much raiseil, for several days it was dangerous getting on and ofl" the ice there. Early in April the thaw set in. part of the lake ice increased the jam at St. Ann's, and it was faid very little of the water from the Ottawa passed that point, it passed for some time in the Back River channel. That thaw broke up the ice on the upper lakes, rising of the waters in the channels brought it down, till it came in contact with the jams on the shoals between Lachine and Beauharnois, and there increased the obstruction which held back the water, flooensive surface works. The nix phteea referred to may be dencribed aafollowH : 1 . The shoals above the Victoria Bridge — When the ice foruis there and is addei<-*«8ur(>ineQis \ny meinoratiduiii contained.

The obstructions begin atiove the VictorinBridge and extend to tlie city front, taking in the St. Lambert wharf and shoals, also the south channel at St. Helen's Island, and the north channel from St. Helen's down. The removal of any one obstruction would not perfect the remedy, inasmuch ns the damage caused by floods extends from the foot of Beauhar nois canal to all the low lands, as far duw i at times as Sorel, when ice jams form on thf islands below Sorel. Therefore, there appears to exist a fair claim on the Oovjprnni.'nt for assistance, such as has been given >h rhiall- er streams and less important places, i'arlio- ment should act at once. CITY AND SUBURBAN DRAINAGE. When the city undertakes to perform works necessary to keep out river floods, ex- tensive drainage is ',eeaed for surface water from thaws and rainfall:^ over a large area ou tfide ol the city ,— its drai nage,water works , and that of the city must be provided for, and in a great measure taken to discharge far below the cily. Any system which does not embrace all outlying lands draining to- wards the city, cannot w considered reliable. If the connection between citr drains and the river is shut off there will be floods in the spring, caused by the drainage and thaws or rains, unless provided for. Therefore, it is important to make arrangements with all outside municipalities to provide for their part of the expense of drainage, or to become a part of the city. Should the city find it necessary (as I believe it will) to carry drainage through the municipality north- east of the city, power to do so, or annexation, would be necessary. The land draining to the city extends from beyond Moi! lanrlfl on the mountain, along the mouii.' :. : . -.'< 'i> its north .'ast end, thence to i, n ' . -.'le end, t' rii,:h (o Petite C''i> ' n '■ jng the higii lands north eao-cil^ lu below Hochclaga. There will be added to this the drainage of St. Gabriel, parts- of Verdun, and all fow lands north of the canal- from the city limits, for some distance above St. Henry. The City Surveyor would have no difficulty in preparing a plan shewing the limits of the territorjr which sends its water shed to with- in the city limits, and the distance below the city it shoukl discharge. In consequence of the insufliciency of the Craig street and other tunnels, it would be necessary to conetfuet others at higher levels, each commencing at the extreme western proposed extension of city limits, and ex- tending to the proposed south-eastern limit or near it; these discharge into one or more larger tunnels affording sufficient capacity, in(» veucia,— ««oh a removed would ol)HlruclionH beuin Hiiil extend to tlio St. Lninttert wlmrf III) cliannel at 8t. )rtli channel from ! removal of any not perfect tUe e damage cauHcd p foot of Beauhar landH, aafar duw i f janm form on the fore, there appears lie Oovprniii .'-i', for en given » •! i^ll- ant placet*, i'arlio- N DRAINAGE, takes to perform ut river floo«l», ex- for surface water over a large area nage, water workn, L be provided for, kken to discharge VHtem which does lands draining to- ionsilered reliable. a citr drains and will be floods in Irainaae and thaws for.

St. Helen and the an that between it brmer is so floored and crossed by hard trap rocks that the St. Lawrence has as yet produced but little eff'eot in wearing tlieni down, while in the latter it has cutout a channel between thirty and forty feet deep, through which the ciiic"f part of its waters rush wiih a velocity equal to six miles por hour. It is computed that by this channel alone upwards of a million of tons flow past tiietown every minute. Between thin point and Lake St. Peter, about (ifiv miles down, the river has an aver- age breadth of two miles, and proceeding in its course with a moderate current, acceler- ated or retarded a little according to the presence or absence of shoals, it enters the lake by a multitudeof channels cut tlirough its delta, and forming a group of low flat alluvial islands. The frosts commence about the end of November, and a margin of ice of some strength soon forms along the shores of tlie river and around every island andproiecting rock in it; and wherever there is still water it is immediately cased over. The wind act- ing on this glacial fringe, breaks off portion" in various parts, and these proceed mg down the streiini constitute a moving border on the out-'ide of the stationary one, which, as the intensity of the cold increases, is contin- ually augiiiented by the adherence of the ice-sheets whicli have been coasting along it ; and, as the stationary border thus robs the moving one, this still further outflanks tlie other, until in some part the margins from the opposite shores nearly meeting, the float- ing ice becomes jammed'up between them, and a night of severe frost forms a bridge across the river. The first ice-bridge below Montreal is usually formed at the entrance of the river into Lake St. Peter, where the many channels into which the stream is split up greatly assist the process. As soon as this winter barrier is thrown across (generally toward Christmas) it of course rapidly increases by stopping the pro- gress of the downward-floating ice, which has by this time assumed a character of con- siderable grandeur, nearly the whole surface of the stream being covered with it; and the quantity is so great that, to account for the supply, many, unsatisfie>l with the supposi- tion of a marginal origin, have recourse to the hypothesis that a very large portion is formed on and derived from the bottom of the river, where rapid currents.exist. But, wliatever its origin, it now moves in solid and exten- sive fields, and wherever it meets with an obstacle in its course, the momentum of tlie mass breaks up the striking part into huge fragments that pile over one another; or if the obstacle be stationary ice, the fragments are driven under it and there closely packed. Beneath the constantly widening ice-barrier mentioned, an enormous quantity is thus driven, particularly when the barrier gains aay posttioa where the current is stronger than usual. The augumented force with which the masses there move, pushes and packs so much below, that the spac^ left for the river to flow in is greatly diminished, and the consequence is a perceptible rise of the waters above, which indeed from the very first taking of the bridge gradually and slowly increase for a considerable way up. There is no place on the St. Lawrence where all tiie phenomena of the taking, packing and shoving of the ice are so <:ranil- ty displayed as in the neighboiirhoocl of Mon- treal, The violence of the currents is liere so great, and the river in some places ex- pands to such a width, that whether we consider the prodigious extent of the masses moved or the force witii which they are propelled, notliing can afford a more majestic speitacle, or impress the mind more thor- oughly with a sense of irresistible power. Standing for hours together upon the bank overlooking St. Mary's Current, I have seen league after league of ice crushed and broken against the barrier lower down, and there submerged and crammed beneath ; and when we reflect that an operation similar to this occurs in many places from Lake St. Peter upwards, it will not surprise us that the river should gradually swell. By the time the ice has become stationary at the foot of St. Mary's Current, the waters of the St. Lawrence have usually risen several feet in the harbour of Montreal, and as the space through which this current flows affords a deep and narrow passage for nearly the whole body of the river, it may well be ima- gined that when the packing here begins the inundation rapidly increases. The confined nature of this part of the channel a fiords a more ready resistance to the progress of the ice, while the violence of the current brings such an abundant supply, and packs it with so much force, that the river, dammed up by the barrier, which in many places reaches to the bottom, attains in the harbour a height usually twenty, and sometimes twenty-six feet aiiove its summer level ; and it is not uncommon between this point and the foot of the current within the distance of a mile, JO see a difference in elevation of several feet, which undergoes many rapid^hanges, the waters ebbing or flowing according to the amount of impediment they meet with in ttieir progress, from submerged ice. It is at tins period that the grandest move- ments of the ice occur. From the effect of packing and piling and the accumulation of the snows of the season, the saturation of these \yith water, and the freezing of the whole into a sojij body, it attains the thick- ness often to twenty feet, and even more; and alter it has. become fixed as far as the eye can reach, a sudden rise in the water, occasioned no doubt in the manner men- tioned, lifling up a wide expanse of the wiiole covering of tue rirer so high as to free and M ptart it from tlie many points of rest and re- sistance ottered l»y tiie tottom, where it had l«en packfd deep enough to touch it, the vavt mass is fet in motion ly tlie whole hy- draulic power of this gigantic stream. Proceeding onward with a truly terrific niHJesty, it piles up over every obstacle it encuunters; and when forcerly or fifty feet. In front of the town of Montreal there has lately been built a niag- njflcent revStenient wall'of cut limestone to the height of twenty-three teet above the summer level of the river. This wall I's now ft great protection against the efficts of the ice. Hroken by it, the ice pdes on tlie street or terrace surmounting it, and there stops; but t)e(bre the wall was built, the sloping bank guided the moving mass up to those of gardenM and houses in a \ery dangerous i manner, and many accidents used to occur. ' It lias lieen known to pile up against tlie side of a house more than 200 feet from the margin of the river, and there break in at the windows of the second floor. I liave seen it mount a terraced garden twentv feet aliove the bank, and crossing tlie garden enter one of the principal streets of the town. A lew years before the erection of the revfile- ment wall, a friend of mine, tempted by the commercial advantages of the position, ven- tured to build a large cut-stone warehouse, 180 teet long and four or five stories high, cIoFer than usual upon the margin of the harbt.)ur. The cellar-floor was not more than eight feet above the summer level of the river. At the taking of the ice, (he usual rise of the water of course inundated the lower story, and the whole building becoming surrounded by a frozen sheet a general expectation was' entertained that it would be prostrated by the first movement. But the prtiprietor had taken a very simple snd eflectiial precaution to prevent this. Just l«lore the rise of the waters he secure- ly laid against three sides of the building, at an angle of less than 4a<', a number of stout oak logs a few feet asunder. When the movement came the sheet of ice was broken and pushed up the wooden inclined plane thus formed, at the top of which meeting the wall of the building, it was de- flected into a vertical position, and fell back. In this manner such an enormous rampart of ice was in a few minutes pinceil in fnint of the warehouse as completely fhielded it from all possible danger. In some year^ the ice has pilaJ up nearly as high as the roof of this building. Another gentleman, encouraged by the security which this warehou^'e apparently enjoved, erected oneofgrent strength and equaF magnitude on the next wiiter lot, but he omitted to pro- tect it in the same way. 1'he result might have been anticipated. A movement of the ice occurring, the great sheet stnick the walls at right angles, and pushed over the building as if it had been a house of cards Both positions are now secured by the re- vetement wall. Several movements of the grand order just mentioned occur before the final setting of the ice, and each is immediately preceded by a sudden rise of the river. Sometimes several days and occasionally but a few hours will intervene between them; and it is fortunate that there is a criterion by which the inhabitants are made aware when the ice may be considered at rest for the season, and when it has therefore become safe for then) to cut their winter roads across its rough and pinnacled surface. This is never the case until a longitudinal Ofiening of consid- erable extent appears in some pan of St. Marv's Current. It has embarrasses' "<>any to ^ive a satisfactory reason why thi.. 'ule, derived from the experience of the- peasantry, should be depended on. Buttheexplanation is extremely simple. The opening is merely an indication that a free sub-glacial passa^ has been made Ibr itsel f by the water, through the combined influence of erosion and tem- perature, the effe«< of which, where the current is strongest, has been sufficient to wear through to the surface. The formation of this passage shows the cessation of a sup- ply of submerged ice, and a consequent security against any further rise of the river to loosen its covering for any further move- ment. The opening is thus a true mark of safety. It lasts the whole winter, never freezing over even when the temperature of the air reaches 30" below zero of Fahrenheit 5 and from its first appearance the waters of the inundation gradually subside, escaping tlirough the channel of which it is the index. The waters seldom if ever however fall so low as to attain their summer level ; but the subsidence is sufliciently great to demon- strate clearly the prodigious extent to which the ice has been packed, and to show that over great occaaional ar. as it has reached to the very bottom of the river. For it will immediately occur to every one, that when the mass rests on the bottom its height will not l)e diminished by the subsidence of the water, and that as this proceeds, the ice, according to the thickness whicli it has in various parts attained, will present various elevations after it has found a resting-place beneath, until just so much is left supported by the stream as is suflicient to permit its free escape. When the subsidence has at- tained its masimum, the trougl) of the Si. Lawrence therefore exhibits a glacial land- scape, undulating into hills and valleys that run in various directions, and while some of the principal mounds stand upon a bane of 500 yards in length, by a hundred or two in breadth, they present a height of ten to movpnient of the slipet Rtnick the i pushed over the a house of cardf> ecu red by the re- tlie grund order re tlie final f>etiin^ )edia(e]y preceded •iver.

Le tout numblement Boumia, CYRIAC LABELLE. 363 Rue Workman, St. Cun6gonde. To His Worship the Mayor and the Alder- men OF THE GiTT of MONTREAL. The Memorial of the Council of the Montreal Board of Trade, Respectfully Sheweth, — That the Council of the Montreal Board of Trade having carefully considered the matter of the periodical inundations of the lower districts of this city, desires earnestly to recommend that the Civic Authorities do, without loss of time, make a vigorous effort to establish the cauaea of, and find a remedy fort these recurring calamities. That the importance of the subject ia too obvious to render argument necessary, and it is needful only to point out that, as a matter of fact, the river never rises above a certain level without causing a considerable money loss from the destruction or damage of property and merchandize, while thia loss, gte&t as it is, is of less moment than . the misery caused to large numbers of people who reside in the district so flooded. That, in addition to these obvious evils, the first effect of the rise of the river being to reverse the flow in all the drains and sewers, all the cellars and streets in these districts are saturated with sewage, and therefore that in parts of the city where no outward efTecta of the flood are apparent, aewage gas must, as a matter of course, be forced into the dwellings with consequences to the public health wnich cannot be over- stated. That the council of the Board of Trade, while desirous of avoiding all intrusion on the province of the civic authorities, con- ceives it to be necessary to make a specific atatement of the course it is prepared to re- commend, as follows : — The enquiry now being conducted by a special Committee ought to be continued, the fullest powers be given to such committee, and a liberal ap- propriation of money made so that the beat engmeering and professional talent may be engaged to make the necessary surveys. It should be the duty of those engineers to report fully on the causes of these floods, and to present a apecific plan or plana for their prevention, with eatimates of outlay. The date at which such report is to be made should be now fixed, though it might be hereafter extended if requisite. It is obviously necessary that no time should be lost, as the river in its winter condition can now be examined and surveyed, and, in addition, it is hoped that some steps may at once be found practicable to prevent, or at least to mitigate, the effects of the spring-flood which many consider probable. That the Council of the Board of Trade believes that the civic authorities will carry with them the approval of the mercantile and manufacturing community, and of the citizens generally, in dealing with this ques* tion in a vigorous and liberal spirit. That it having transpired that the Repre- sentative of the Board of Trade on the Inun- dation Committee- ia abaent from the city, the Council have thia day nominated R. Paton McLea, Esq., in hia place, and desires further to say that its members are prepared to aid the proposed enquiry in every way in their power. The whole respectfully submitted. GEO. A.

Observations on the changen of the wea- ther, wind and level of the water, as noted by Chs. L6ger at Lachine since the I6th of December, 1884, viz z Dec. I6th. — All the rivers were open in the morning, the same night, very cold. Dec. 17, 18, 19 and 20, very cold, with northeast wind and snow. Dec. 21. — All the rivers were froisen over and people were cro!>sing the same on foot, excepfing within three miles of the town of Lachine (to Isle Dorval), which is always open. On the same day (the 21st) the wind changed to southwest and blew a gale all day and the ice on Lake St. Louis did not budge, the weather kept cold until the 27th ; from the 28th until January 13th the wea- thei" has been very mild, with a great deal of rain about every other day, with winds from the east and south the greatest part of the time, which caused the ice along the Lachine shore up to the Island Dorval to break close up to the beach, the f^asil ice floated to the surface and moved down the river with the broken'ice which caused the water to rite tome in Montreal. If the piers were built at Lachine the river would all freeze '^ver from the piere to Isle Dorval and would thus prevent the making of frasil ice, and would also keep the ice there instead of drifting down the river to Montreal and cause a jam and rise of water there. Everjr year the ice takes by a cold north- east wmd, from Beauharnois to Lachine, with the exception of the three miles above mentioned. Before the year 1876 the four gates of the Lachine lock used to remain open from about the 16th June till the 16th September, with only about 6 inches of fall between Beauharnois and Gdte St. Paul locks. Since the building of the new canal dam, the water at the heaid of the pier is one foot higher than it was before. From what information I can gather from the inhabitants should the piers cause the water tQ rise during the winter season it would cause no inundation, even 4 feet, in the vicinity of Lachine. RespsctfuUy submitted by Chs. Leger, Light pier keeper, Lachine. Lachine, 14th January, 1885. To the Inundation Committee, Montreal. MoNTBBAL, May 18, 1885. A. A. Stitinsoit, Esq., C^irman Committee on Floods : This is as near as I can remember the nam<) of the committee. A few days ago you were good enough to say you were willing to read a letter of mine in reference to our annual floods, and how to prevent, or, at least, mitigate them. In pursuance of that desire, I beg to say that 1 have had a map of Montreal and vici- nity before me for a year, and the more I look at it the more I feel satisfied that three things, if done, would greatly conduce to this desirable object in view. First — Muffatt's island and the pier thence to St. Lambert shore, should be removed. Second — The channel south of St. Helen's Island should be deepened. In this I find a correspondent of the Gazette, Mr. Sorby, agrees in a letter he wrote some days a^o. Third — Isle Ronde should be partly or entirely removed. By these acts, I would expect to make a direct course tor the ice on either side of St. Helen's Island, and thus relieve the pressure upon the wharves. So much for the city itself. Now, with regard to Point St. Charles, or further up, the difficulty is not so eas^ to solve, because of the formation of Laprairie bay. When the lake ice comes down, it natural- ly pushes towards Laprairie, where we find as it were a large mouth with closed teeth (the piers of Victoria bridge) holding it back just at the entrance to a comparatively narrow place, thus preventine the larger mass of ice, which is collected at breakmg- up time, from freely passing down. The Victoria" bridge I hold to be in a bad spot for our bi-yearly welfare. However, there it is, and to stay, therefore we must fight around it for success. Before closing I might venture a sugges- tion or two for what they are worth. That old pier which runs out into the river nearly parallel with Victoria bridge, ought to be removed or built over so as to point down the river, instead of nearly across, as at present. And, finally taking a jump down toPointe> aux-Trembles and the islands that crowd the channel on the south of Isle St. Therese, it occurs to me that the removal of 8ome of them would make a clearer course for the moving ice, and thus greatly conduce to the end in view. I don't indulge the idea that I have made any discoveries that are new, and fear that some of my suggestions, if deemed good, would involve too serious an outlay for our purse, but I venture to express my views to May 18, 1885. I Floodt : m remember the * good enough to 1 a letter of mine I floodn, and how gate them. we, I beg to ray [ontreal and vici- , and tl)e more I el satisfied that greatly conduce iew. d the pier thence Id be removed, ith of St. Helen'8 In this I find a ttU, Mr. Sorby, ome dayn a^o.

We have as closely as possible adhered to the instructions ot Uis Excellency, and although the members of the Commission, as appointed by His Excellency the Uover- nor-(ieneral, have not been able to meet together latterly, yet as the outhnesofthe plan were agreed on and put in writing at their last meeting, and an from the first there was no difference of opinion as to the prin- ciples on wiiicl} the plan of relief should be founded, we trust that His Excellency will be convinced that the best endeavors of all the members have been used to further the end in view.

REPORT On the causes of the periodical Inundation of part of the City of Montreal called OrifSntown or St. Ann's suburbs ; on the possibility of removing those causes, or of obviating their effects. In pursuance of the commands of His Ex- cellency the Governor-General as conveyed in the civil secretary's letter of the 16th January last, relative to the periodical inun- dations in the St. Ann's suburbs of this city, the commission appointed bv His Excellency have the honor to submit the result of their inquiries and examinations, with plans, sections and estimate founded thereon of the probable expense of protecting the city from this c.*vl.imity. The subject naturally divides itself into several principal sections. DIVISION OF THE SUBJECT. 1. The rise of water in Montreal harbor at the end of December, or beginning of Jan- uary of each year, and on the breaking up of the ice in the Spring. The natural and artificial causes leading towards this result, and the consequent flooding of Griffiiitown. The possibiiity of removing those causes or of obviating their effects. RISE OP ST. FIERRS RIVER. 2. The rise of water in St. Pierre River and its effects on the inundation of the city and neigh t>orhood with the means of prevent* ing the evil. BCWERS, DRAINS. .3. The sewers, drains and their courses by which the backwater of the St. Lawrence is admitted into the city before the overflow of the banks and upper quays. STREAMS WITHIN THE CITY. 4. The small streams which usually fall into the St. Lawrence within the jji-ecincts of thecity, and the means of guarding against their overflow when their uiiual course is stopped during the inundation. RISE IN HARBOR. First. The rise of water in the harbor is obviously caused by the accumulations of ice from the rapids above, which, being stopped by the field ice below, is forced uncfer it Iron* the pressure above until it grounds on the shoals in and below the harbor, and being confined by the narrow channels on each side of the island of St. Helen, forms a succession of dams as far as the head of the Is hind and the new market, from whence the inundation was on a dead level this winter as far as the canal ; and from the information we have obtained it appears that the deviation in other years is not material. The great body of ice in the centre of the river, when arrested in its course, shovu not only down* wards but sideways towards the shores, and even backwards when out of the current as below Windmill Point. ' lOE DAMS. It then grounds on the shuals and forms accumulations which in some instances have done damage to the houses along the quays. The accumulations on the shoals and wharves at and above the new market being nearly parallel to the shore do not, in our opinion, materially affect the rise of water in the river. The communications from intelligent and observing residents who have favored us by their written or personal communications show that the accuiuuiatiuns vary in extent and situation. That the relative height of water in different years corresponds with the alternations of frost and thaw before the ice becomes fixed, and that, when the frost is very steady at this period, a comparatively small rise of water may be expected, pro* so bably from the mall quantitj of floating ice wliicli coiiicH down the river. 0AU8B9 OF UNEQUAL RISE OF WATER IN DIFKGHENT YEARS. It is also generally observed that when the ioe pasfles down tlie east channel without choking or " shoving " that there is no excessive rise of water in the harbor, and also that if this channel be choked, as well as the western one, thiu the greatest rise is to be apprehended, us v us the case this winter, the " air hole" or vent being below St. Helen's IFFEOT OF THE WHARVES ON THE INUNDATION. These facts, connected with the parallel situation of the accunuilations to the shore, and the unilurni level of the inundation above the new market, apparently prove that the wharves have no ott'ecl on the'inundatiou. The proportion to the breadth of the river is very trilling. RISE IN FORMER YEARS. This view is corroborated by several intel- ligent correspondents, who vouch from personal observation that the water has risen to a greater height belbre these improve- ments were made, and, in particular, about 60 years ago, when the water covered the whole of the southern part of St. Paul street. Several years after this, the lower floors of the Grey Nunnery were mundateii to a great depth. In the winter of 1809-11) the water rose high enough to float timber over Qrey Nuu street. In later years the greatest rise was that of 1837-38 when the water rose about one foot higher than the present year. That in 1839- 40, although higher than usual, was two feet lower than that of this year. DURATION OF FLOOD. The duration of the highest winter flood varies. It generally does not exceed two days, as was tiie case this year and the preceding, but in 1837-8, which was a very nuld winter, the flood was very high, though perhaps not at its highest, during 14 days. Some relief may however be expected in less than 24 hours. The city is always more or less affected by it, in the- cellars for several weeks. HEIGHT OP FLOOD ABOVE LOWEST WATER. The greatest flood is about 20 feet above summer level in the Harbor and about 12 feetdifference ai St. Mary rapid, between the two periods at that place. SPRING FLOOD. The spring flood is lower and of less dura- tion, as the ice is then unequal to support a great head of water, but troni the greater body of floating ice more damage has been occasioned by tiie latter to the houses border- ing the quays at this seasou tha.i ly tl^e water. The niost remarkable effect of ice wns in 1792 or 3, and in 1H32 the water rose to the height of the present quay wall. ThetemperatHre has also un effect on the spring flood, and southerly winds, by detacii- ing large portions of ice, increase the accu- mulations or the flood by the accompanying rain. If the river is open at the current St. Mary the rise of water is not to be dreaded in the spring. From the foregoing facts and the levels taken for the commissioners, and from the coincidence of the accumulations with the narrows and shoals at and below the head of the Island and the new market, we are of opinion that the obstructions aflecling the inundation commence at those points, and continue downwards on both sides of the Island until the river opens below it. As before stated, there is no very high flood if the channel is open on either side of St. Helen's, which appears to {jiVove that there is always a sage below suflicient to relieve the town. ST. PIERRE RIVER. Secondly. Dams of ice similar to those before mentioned are formed above the harbor and in the channel inside of Nuns' Island, which raise the water above them and back it up the St. Pierre River until it overflows its banks, when it flows in a rapid stream downwards on the east side of the canal, and through the culvert at St. Gabriel's farm to the west side. This rise is nearly simultaneous with that of the back water in the harbor, and meets the latter flowing southwards about the St. Gabriel's farm. Its level is about two feet above the harbor backwater, and has therefore much increased the mischief caused by the inunda- tion. It has flowed over the canal bank in several years, and in 1837-8 to a depth of 4J inches, and probably caused the very great flood of that year in GriflSntown. The backwater did not, in the present year, flow up the St. Pierre beyond the culvert under the level near Mr. Gregory's. Should it do so in other years it would be diverted on that side from the city by a ridge running from Mr. Gregory's we-twarde across the upper Lacliine road to the Cote. This is tlie dividing ridge between the water of the Holwell creek, atid ttiat of the rivulet, flowing through the Tanneries to the St. Pierre. It has been proposed to embank the St. Pitrre, to prevent its overflowing on the east side of canal, but this work by preventing the relief aftbrded by the overflow, might back up the water to a greater height along the banks of the St. Lawrence above the St. Pierre, tnd up the valley of the latter. 180U Iha.i ly tLe Feet of ice wn« in : water ro8e to tlie wall. ttii effect on tlic winds, by di'tacli- iicrease the accii- ihe accompanying ! current St. Mary be dreaded in the ;t8 and the levels ?rH, and from the iilatioHH with the below the liead of market, we are of one atlecling the those point", and both sides of the 8 below it. is no very high 1 on either side of to jjt'ove tliat there fhcieiit to relieve [VEB. similar to tboee rmed above the si inside of Nuns* vater above them erre River until it it flows in a rapid i east side of the • culvert at St. side.

DRAINS AND 8KWERS, ETC. Thirdly. The backwater rises in the cellars of the houses within its sphere, nearly as fai-t as in the harbor, through the St. Ann's creek and other drains, and also by quicksands or gravel below the level of the quay wall. The remedies we shall after- wards submit. QtTICKSANDS. The influence of the quicksand is proba- biy much less than is generjilly supposed. If it cannot be cut oft", it will at leant require small means to carry it off. 8TRKAM8 WITHIN THE CITY. Fourthly. The streams falling into the St. Lawrtnce, within the precincts of the city, contribute to the inundation, and the mode of remedy requires consideration. HOLWELL OREEE. The Flolwell creeK is merelj the drain of a marsh, on the west of Uppei-'Lachine road, as far as the ridi'e before mentioned on the city side of the lannerief. It is joined near the brewery of Mesnrs. Dow and Dow by an offset from the St. Pierre, parsing tlirough the St. (Jabriel culvert. Tlie latter stream can be confined to the east side of canal during an inundation. The Hulwell creek discharges at Point & Cailiere. MOUNTAIN STREAMS. Thero is another stream which descends from the Uote d Barron and crosses Bleury street near the upper end. On arriving at a swamp at the head oCSt. Lawrence suburb, it passea by a water course intq the Craig street tunnel, which meeta the Howell creek before its discharge at Point 4 Callidre. This stream will be herealter adverted to. REMEDIAL PLANS PROPOSED BY INDIVIDUALS. Several plans have been proposed bv in- dividuals for prevention of the rise of water in the harbor. EXCAVATION IN THE BED OF THE RIVER. The most obvious remedy is to deepen the ahoals in the west channel, and to lower the small island at tlie foot of St. Helen's to about three feet below Bummer level. The eipense attending this plan would be verv great, the effect uncertain, as it would afForcl very little aiiditional relief m the chaunel, which is 37 feet deep at low water. The effect anticipated is that it would afford scope for the escape of the ice below, without forming dams. In thesummer it would have the injurious effect of lowering the water in the Harbor, but, on the other hand, it would diminish the rapid of St. Mary, by lowering the liead, and allowing the water to spread. Another objection to this plan is that it would require several seasons to complete it. Although it is not recommended by the commissioners for the present time and purpose, it may deserve attention at a future time, as an auxiliary means of relief, keeping always in view the effect it would have on the harbor. The shoals above the head. of the current St. Mary may be removed without risk. PROPOSED MOLE AND IT8 PROUADLE ErFECTB.

In France, I have read, the cornice road troin Marseilles to Oenoa, some 160 miles, built through rock the greatest part of the way, was done almost entirely by prisoners from Toulon, under the flnt Napoleon. In England I have myself many times seen a gane of prisoners at work building the WeymouUi breakwater. It is an immense structure, about live miles long, and would coat many millionsofpounds, but for utilizing that which is in Montreal a " latent power." Yours truly, F. J. Oilman. H6 St. James Street, Montreal, 19th January. Sir : — At the request of Mr. George Drummond, I beg to lay before you some points in connection with my scheme tor relieving the city from floods, which was published in the Utar la«t week. These points are as follows:— Firstly — The still water harbor mentioned as being possible after our drains had been »11 diverted into the Craig street tunnel, was only referred to as an improvemeut which might be carried out ; — it forms no part of the projeot for avoiding the floods. iSecoN<%— The extension of the Craig fltNet tunnel down to the Buisseau Migeou is in any case very desirable, for during very high water the drainage lias no proper out- let! but keeps floating about under tiie city with the rise and fall ot the water, gradually mixing with the water in the river, and not only generating gases which must be very iqjurious to tiie uealth of the city, but also depositing large quantities of solid matter in the drains. rAir<%— If the drainage of St' Gabriel was all brought under tlie canal to join the ex- teasion of Craig street tunnel, a splendid opportunity would be afforded of flushing the tunnel with water from the canal. Fourthty-^)x9 extension of the Craig street tunnel will be required at no very dis- tant date in any case. Fifthly — After diverting the drains from the Joarbor, we should have no more com- plaints about the polluted water along tUe river front. Sixthly — From remarks I have heard, I would wish to explain how I propose to deal with the drainage during floods. I propose, when necessary, to shut oif the connec- tion between the main drain and the river at the Buiflseaa Migeon, and either pump it over the sloioes into the river through a long pipe supported by stays, or through a pipe carried along the bed of the river to some point out of the way of navigation, and pro- tected at its extremity with a crib-work i or else let the drainage flow into a reservoir during the floo«l8, and let it flow out when the water tails siifiioieutly ; on these last points I have no data which would enable me to form an opinion as to which would be the best method. Sevmthly— The cost of the scheme I pro- pose can i>e definitely ascertained, and it* success is certain ; whereas, in dealing with the river, unless St. Helen's island be re- mc^ved, which is quite out of the question, no one can tell what the success would be; under certain conditions a flood could be avoided, but under others the water is cer- tain to rise. Eighthly— To raise the level of the streets would only give a small measure of relief, bS the cellars and yards would stiil have to be filled and the houses raised — it being re- membered that cellars are very necessary to store provisions in. Ninthly— 8inoe writing to Mr. Drummond, I nave seen the report of the Uoyal Engi- neers on the question at issue, and, taking into consideration the changes in the city, their proposal seems almost the same as mine. Tenthly— The scheme I propose would not only reUeve the city from floods, but also give us a perfiect system of drainage. Mnally—l wrote the letter published ia the Star simply as a citizen who has an interest in the welfare of Montreal. I have not, as has been estimated, any " axe to grind " in the matter, as I have not yet found surveying in Montreal sutficient!y profitable to be at>le to invest in flooded cellars on St. Paul street, nor do I expect to derive any professional benefit from my scheme, as the works, if carried out, would be under control ot the City Surveyor j and, in fact, any investigation into the condition of the river would be more likely to be pro- fitable, as Mr. Rielle might be called on to furuisti a copy of the large plan which he has of the river St. Lawrence on a scale of 200 feet to the inch, and which comprises that part of the river lying between Lachine and the Boucherville islands, shewing the contours of the ground, the level of the water at various points, and well established bench marks along each side. Your obedient servant, H. iRwm. Alderman Stevenson, Chairman of the InuadaUon Committee. 84 146 St. Jamci Stkket, 4tli February, 1886. Sir I— Allow me to call your attention to one point in the published account of Mr. St. Oeor(5e'B report which I think requires explanation- , , Mr. 8t. George cites the fuct that the Worthington engine can only deliver 8,000,- 000 gallons per day, as proof of the imprac- ticability of pumping the sewerage in tune ofHoixis. , , , Mr. St. George seems to have overlooked the fact that the 8,000,000 gallons have to be raised some 200 leet, whereas the sewer- age at the Ruisseau Migeon outlet would only have to l»e lilted some 16 fet-t. It follows from this that an engine of the same horse-power as the Worthington could deal with 100,000.0' i) gallons of sewerage at the point stated above. Besides, an engine could, owing to im- provements, be now boutiht at the same price as the Worthington, capable of pump- ing about 26 per cent, more, so that, for the same price as the Worthington, we should have an engine able to pump 126,000,000 gallons per twenty-four hours. Again, the Worthintjton type is by no means the most suitable for low lifts. In the " Soientiflc American Supplement " for 9tb August, 1884, you will see an account of a centriTugal pump(for emptying the caissons of a floating aock) which has a capacity of some 208,800,000 gallons per 24 hours. With regard to the water from the upper part of the citv, I had no idea that it ais- charged into tue Craig street tunnel. I was under the impression tliat it was conducted along a higher level drain, and emptied into th<> Colborne avenue tunnel. In this, as in most other matters relating to tlie scheme I proposed, I could propose no details, as I am unable to get at the necessary data. Surely no sane engineer would pro- poae to pump the drainage ot the higher parts of the city into the river. If Mr. St. George would inform Messrs. R. H. Buchanan & Co. Uf the quantity of water to be pumped per 24 hours, and the height to which it would have to be raised, 1 hav9 no doubt they would give ^ou an approximate tender on very short notice. I do not propose to trouble you any more oa this subject, as I think I have succeeded ill turning the attention of the authorities from the idea of dealing with the river to tba more practicable ancfless costly scheme of keeping the water out of the sewers and raising the bankp where necessary. This was the objrct I hod in view iu writing my letter of 12tb January last. Your obedient servant, H. Irwin. Alderman Stfrenson, Chairmtn Inundation Committee. Ovid M. Gould, Esq., tastifled aa follows :— I called here to draw the attention of the Committee to the fact that the City Surveyor has been taking levels of the river, and in conversation with him he stated that he was not authorized to make a very extensive survey :— The levels which have been already taken So to sliow that the dam which causes the coding of the cify now seems to be located sni8 to be located nde and Victoria Surveyor that it t up with dyna- oh might nut be is Committee re- »e City Surveyor more extensive rvey, inhieopin- blovi up tlie ice explosive, an an tructed to make in if the obatruc- ig of Point St. vater backing up no M.

To remove the islands, Isle Honde und St. Helen, would do no good. They talk of abutments of u^e in the river ; there were 4 or 5 built where the bridge crosses, by the advice of some enKineers, to retain the ice 111 theLaprairie bay. They proved to be an expense and for no purpose, so they weie broken up and carried away by the ice; that proved their great service. I would lay : remove those small island.^ below Boucherville island, — t'jat would give more room to form a greater passage and prevent tiie choke here ; then if the river is Iiigh ill the fall we are not in so much danger 01 being troubled, as the passage is increased thereby.

CoTG DBS NmoBS, MoNTBBAL, Jan. 20, 1886 Alderman Stevenson, S'.B, I understood that a meeting of the Inunda- tion Committee would !« held in the City Hall on Tuesday lust at 3 p. m. Under that impression I wrote the letter left at your house on Tuesday night, intended to have read same myself, and maiJe certain corrections that it seemed unnecessary to writedown. The most pertinent that occurs to me juMt now is after the words " Craig St. Tunnel " I should have said : A separate tunnel could be made to run parallel with the river a few feet inside the revetment wall, and by this means drain Point St. Charles, Grimntown, etc., in fact, all sewera se thst now empty into the St. Lawrence — said tunnel to be connectei at the lower end with the existing Crsig street tunnel, and the wiiole carried to a point below the ioe barrier previously referred to. Yours truly, F. J. Oilman. GUARDING AGAINST FLOODING. MoirrRBAL, April 28, 1885. To the Editor of the Herald. Sir, — Surely it is possible in future to prevent the disastrous Hoods in the low-lying parts of this city. Near Penzance, England, there is a tract of land, some five hundred acres in extent, close to tlie sea, that is never flooded, al- though it is some eight feet below high tide. A reservoir of about an acre holds all the surface water froin this land ; it is separated from the sea by a high bank ; at low tide the water is drained otf by two culverts, about 2 feet in diamater ; eacli culvert is laid in cement and slightly sloped at the mouth ; a piece of leather, strengthened on the outer siide by sheet iron, is hung over said mouth of culvert, forminga valve which effectually prevents any water returning, no matter how high and rough the sea. f hese drains are very simple, would last many years, and ought not to cost more than one flood does. Yours truly, F. J. GiLMAN. ^1; I INUNDATION MATTERS. To the Editor of the Herald. 1 am gratified to learn through your columns that the City Fathers are beginning to see the utility of my scheme for preventing the inundations. On the 13th of April last I wrote describing the means adopted to prevent inundations in other countries. On January 18th I forwarded supplements of same to the Chairman uf the Inundation Committee, a copy of which appeared in your isHue of January '26tli, suggesting that as the floods were caused by an ice barrier forming below the city it was advisable to rebuild the revetment wall or put another wall on the river side of same, commencing the foundation say ten feet outiiide the existing wall, and sloping the new wall inwards, so that it would come within 6 feet ot the whole wall at the top of the same, the space between wails to be cemented witit puddled clay ; the new wall could be raised three or four feet higher than the old one, with ridged coping stones at the top of the same, coming to a sharp edge to prevent children walking on top. There would then be a protection for pedestrians in winter m well tm mnMner. Tht« sloping wall would have a tendency to raise the ice wiien Hhortng against it, and so relieve said wall of part of tbe pressure. I further suggested that a new tunnel should be mai a between the town iwill tliea be able the extra amount he water to pass : flood time. You fd for the flow of water by cither deepening the river, takine away St. Helen's Island altogether, or only so much of it as would be requisite for the flood water. Removing part or all of SL Helen's Island would be the least expen- sive, as you could einplov prison labor for the greater part of the work. I ami Gentlemen, Yours respectfully, John Abcheb. Geographioati SociKTr. Quebec March 27, 1886. 2b the Editor o/Thb Star : Sib, — I wish to draw your attention to the state of the waters of the St. Lawrence, which enables mariners to sail from the Louise Dock, Quebec, to Cape Ray, New- foundland, and so pass into the ocean. The Gulf of St. Lawrence is always navigable in spring until the bay ice gets fntothe current, and 80 blocks its entrance with rield ice ; between Cape Ray and Bird Rocks this generally occurs at the end of April, but never in March. The point, however, inter- esting to us in April, is the ice blockade in the river Iwtween Quebec and Montreal, especially as it is believed, with our know- leage of "modern science, it ought not to exist ana, if not removable, it it at any rate preoent' able. My argument consists in my knowledge of the element of water, its power to receive heat and to resist cold. The temperature of the river ti)-.iay is thirty-four degrees, two degrees above freezing j this is not the case With the land or the ice, they asninii- lale nearer the temperature of the atr, which is frequently very cold, and in March, ex- cept when the sun is shining, rarely at a temperature of thirty-four degrees. These fact-- beinjj correct, we have to attribute this early navigation to the river having been kept clear of ice during the winter and it« preparation to receive solar heat early in March. A shall of water, at a temperature above freezing, bein^ pushed and worked np and down by the tide has au etfeet oi> the air, as the vapors can be both seen and felt, enpe- cially when this mass of water extends one hundred miles inland, as is the ca<her thirty-four degrees is above freezing, and all that latent heat is covered up with ice in Lake St. Peter, and no pr«»- tecteil from the sun's rays and all contact with the air, consequently causing delays and late navigation. The captain of the " Aler^ " can do this service as easily as navigating HudsonBay, if he was ordered to report in Montreal, and Canada would gain by having open ports in April instead of in May.

To the Editor oFThe Quebeo Mcrcdry : Sir, — The conditions of the river in the harbor of Quebec have bet'n po entirely satisfactory for the last month that I do not think they can be nuiuli improved. The grand battle against the fl lating ice by three «itean)l>oat8 during the winter has been so eminently euccessful, it will, no doubt he re- newed every year ; and, though the steam- boats lost screwH and received other injuries, yet thev demonstrateti the fact that ice has to yield to superior fore when guided by modern skill. In the St. Lawrence there appears to be two ♦•points" letween Quebec and Montreal, where the ice may Jnm in such a way as to become a public injury, viz. : at the Chaudiere and at lioucherville. The Chaudiere did not bridge this year, no doutit from want of material ; as i'rom the ice being kept in movement by the seven hours of falling tide, against the inflow of four hours, it would reduce tlie quantity of ice to pass througli tl>e narrows. The form- ation of a bridge at tlie Chaudiere is always uncertain ; the nature of ice is to disperse and separate, to melt, but not to adhere ; it is constantly trying to return to tlie condi- tion of water and to flow instead of becom- ing fiolid. When an ice jam does form at the Chaudiere it becomes so solid (twenty feel in thickness) that it only yields by melting and by thf pressure of the Lake ice. The effect of no bridge at Levis, and none at tlie Cliandiere. was probably the breaking away of the Platon bridt bi'in$; on to 1) fur the further wrence), or to naation of Pro* poiisible.

A. A. Stevenson, Esq., City Hall. Dear Sir :— I read with interest the letter in Saturday's Star bearing on the floods, and having until recently lived on the river bank south of St. Helen's Inland, and where my father still resideiii, I have seen conniderable of the river's changes. The only letter in the Star bearing on the real points is the one written by Dr. Mount, and 1 quite agree with him that the present flood has been caused by the mild weather at the time he mentions. Some of the writers suggest the removing of all the islands on the south shore. Now tiiey are the only protection Longueuil has from being drowned out, as the ice anchors around these islands and prevents shoving to a large extent. One wrtter suggests removing Isle Ronde also, and, if we were Americans, S(. Ueleu's island would also be removed. It is the writing of such that prompts me to write this letter. I would like to ask these gentlemen, whatoaused the flooding of La- prairie Bay and also at Isle Perrot and around the Cascades— was it the deepening the cbaaael at these points 7 Certainty not, some people think it is our harbor and river improvements that cause the recent flooding spring and fall, and of course the Government and the Corporation are sup- posed to spend a lot of money — in fact «ill they have, to satisty some people's imagina- tions. The harbor improvements have no more to do with it than the flooding of the other points I have before mentioned, and until we can control the weather it \>* mt- less B pending a lot of money on survevs. Anyone that has watched the river as Dr. Mount has done, must agree with him, a great portion of the city can be made free from flooas by closing the sewers that enter the river above the main Craig Street sewer, at that point to have it pumped into the river. If all the islands on the river were cleared away, and of course the expense would t« something enormous, we would still be as likely to flwiding as at Isle Perrot. I can, if you wish, give a great deal of infor- mation about the forming and breaking up of the river. A good deal of the present cry out is of course " Against the Government J. G. Holland. Qdbbeo, 15th Jan. 1836. To Mr. Alderman Stevenson, Chairman Committee of Inundations. Sir, — Pursuant to your public invitation, will you allow me to make a remark or two. If we look abroad, and observe the coun<>e pursued by other cities, both in America and Europe, we shall find that any great question of construction is invariabi/ com- mitted to the handling of quulitiei experts, as they are commonly designated, " civil engineers." These highly educated, and, ivhat is more to the point, specially edu- cated men, have not only for their guidance the judgment and intuitions resulting in their individual persons from long vears of study and the traditions and axioms of their comparatively modern profession, but they obtain, by the time and labor which they are paid to exert and spend in the local investigation of the particular case, a view as complete as possible of its special nature and requirements. Now, then, qualified men would b^ .no means despise the evidence of former inun- dations, such as you wish to be laid before your committee. They would use such evi- dence, and form an enlightened judgment oa its bearings and value. Then, they would go into the question of probable expense, and submit a scheme for the approval of the citizens, and their qualified representa- tives. In a cause like this, there is something approaching to completeness, up to the mintof an actual laying hold of the work. But when your honorable committee should i I bare heard the evidence and the schemes of •II the old residents who have been interested for years in watching the ice-floes, it will •ot, therefore, be in any position to decide upon the future course of the city in relation to security from floods. Much of the evi- denoe^indall the "schemes" will want severe " tifting," such as enjiineers only could give to them, and it is no disparagement to say of the honorable gentlemen of your committee that, in the absence of the qualiftcation alluded to, they will find their duties little other than burdensome, and in the event ineffective for a final decision. The expense of a scientific enouiry could not be very great, in view of tne extreme urgency of the case, and it is to be earnestly hoped that a commission of experts will be appointed in the premises. In Britain and in Holland, great works of protec- tion have been in existence on the great waterways for centuries past, ana on the Mississippi the subject is constantly re- ceiving attention, and many important " leveet" have been built; although, if our American neighbors would take up this qiiC'ition as a* whole, and complete their banking as rapidly as might be, they would he immente gainert, for it is a work that should not be attempted in driblets. Asking vour patience for these hasty notes, i remain, Dear sir, Very respectfully yours, HeNBT HaMMINO. St Vincent de Paul, 21 Janvier 1886. MoMaiEUR, — Permettez-moi d'attirer totre attention au sujet de I'inondation afin de faire oonnaitre mon opinion.

Votrotr^B humble serviteiir, DIOYME MEILLEUR. Pilot. Georoe W. Stepheks, M.P.P., appeared before the Committee and said : — The question of inundation has occupied the attention of the Council at v(krion» periods since the year 1860. During the term of the late Mr. McQues- ten, City Surveyor, and while I held office, various remedies were discussed, and in- structions given that in future the levels of all new buildings should be given above high water mark, and a plan was adopted of raising the grades of the streets. This was done m many instances. There are two ways of getting rid of the inundation difficulty. Ist. By sluice gates and receiving tanks at the outfalls of the main sewers, pumping the sewage during the stage of high water. This could be done by establishing three pumping stations, one above the Mill Race, roint St. Charles, one at the Custom House, Point k Callidre, a third at Colborne Avenue. Intervening small sewers to be connected to the main sewer interiorly. The Point St. Charles district could be done ver^ cheaply, as the aqueduct embank* ment, with a little repair, already affords protection to this district between the Canal Bank and the river side. An experiment could be tried immediately with this section. The cost would be incon- siderable. . The second remedy is to raise the streets throughout the inundated districts above flood level bv depositing thereon the ashes of the City and> the earth procured from exca- vations. The expense could be met by a local assessment. Under the local assessment by-law of Toronto, construction or reconstruction, (but not ordinary repairs or maintenance of drains, sewers, roads and sidewalks, or for levelling, grading, paving, bridtte-building curbing, sodding, or planting, street sweeping lighting and watering) are charged to the parties immediately ^nefited thereby. This plan is ailopted for* the most part throughout American cities. The adoption of this system would prevent what is called ward grabbing. The reason why our older wards are ne* giecteld, is that the taxes raised from thent are largely spent in developing the unin»- proved parts of the suburban wards, most of which contribute ligittly and draw heavily on the common revenue. If new works were, as they should be, charged upon the locality directly benefited, a large sum would' be set free over the city f^r general purposes. The water in the St. Lawrenoe opposit* the city will rise to flood-he^bt as long aa there are batteries or shoals for the ice to lodge upOD and weather which produ«ee f^nuil. . ik p.p., appeared i : — I has occupied sil at varion» > Mr. McQiies- i I held office, issed, and io- e the levels of ren above high »s adopted of sts.

This would take awav one obstacle and reduce the swiftness of St. Mary's .current. The raising of the streets in the flooded districts would increase the value of pro- perty. I do not think the flooded districts are rendered unhealthy by the mixing of the sewage with the water, or that much sewage is flooded into cellars. The objectionable and unhealthy feature is the allowing the ice to remain in the cellars all winter, and the consequent damp and chilly cellars. Sewage forms but an inflnitesimal part of the flooding water. As a matter of fact sewage air does cot come into houses while the sewers are full of clean water to the arch of the sewer. There being no vacant space in the sewer, there can be no formation of air there to be sent back into the houses. A comparatively empty sewer may gene- rate unpleasant air ; a oewer ftill to the arch with water does not. There is no necessity of spending any money on outside engineering talent. Messrs. St. G'Hjrge and Brittain are perfectly com- peteiit to deal with the question luraotically. Gig. W. StsFBGira. GoTEAC DU Lao, 25 jsnviw 1886. M. L'EoHEVIN STETBIiaON, MOHTaiAL.

This consisted in constructing puddle dams near the outlets of the main sewers leading to the river, with the view of preventing the rising waters, on the breaking up of the ice, froia backing up into the street drains, and thence into the cel- lars of business places and streets in the low- lying districts. The outflow of the sewage being thus ob- structed, pumping stations were required to pump the sewage over these dams into the river. It was deemed advisable, this year, to limit the work to those sewers west of the Custom House, which receive and discharge the sewage and surface water of the St. Anirs ward, that being the district which suffers most from tbexe periodical flood ings, al- though the portions of St Antoine, West and Centre ward'', which drain through McOill, St. Francois Xavier and other streets into the William street tunnel (having its outlet in front of the Custom House), likewise en- joyed the benefits resulting from this under- taking through the blocking of St. Fran9ois Xavier street drain at the foot of that street, •ud its connection, with the pumping cut bv a wooden box drain 2' x 2* and 60 feet long, which your committee caused to be con- structed. Six pumping stations were established : Na I being in Commissioners street, near the Custom House, which received the contents of the sewers of William, McUill and other streets as far east as St. Francois Xavier. The sewer at this place is 14 feet six inches wide and 12 feet deep. The cut was 40 feet long, 16 feet wide and 18 feet deep, (with two side cuts iO x 8 x 15) in which was con- structed a solid dam of puddle clay, 20 leet CD the surface, tapering to 12 feet at the Itottom, and properly secured by heavy tim- bers, with a nume and sluice gate of the full dimensions of the William street tunnel ;the other twentv feet required for pumping and discharge basins. In excavating here, an object of great interest was discovered, the existence of which seemed to be known to very few, viz : the ancient stone bridge, erected during the occupancy of the French, to span the open creek, wiuch at that time ran along the present line of Commissioners street. The masonry seems as strong and substantial to-day as when flrst erected. The cut at No. 2 station, in Mill street, near the canal tail race, at Tate's Dock, was 41 feet long, 24 wide, and 17' 6" deep, with a dam of bine clay, flume and sluice gate, protected bv timbers 20' 6" x 8'. This station received the contents of a large num- ber of drains in Point St. Charles. Nos. 3, 4 and 6 stations were located at the foot of Forfar, (ionwav and Britannia streets. No. 6 station, in St, Etienne street, near the abutment of the Victoria Bridge. For the further protection of this part of the city, it was found necessary to construct an earth enbankment from Forfar to Bri- tannia street, 477 feet long, average depth 7' 6" ft., average width 9 6" ft., with a small flume and flood-gate in surface drain on Britannia street, and a similar enbank- ment, south of that street, on river front, 12 feet long. 4 feet wide, 3 feet deep, with a sluice and gate. It was also found necessary to erect enri- hankments at various places above Victoria Bridge on the Rifle Ranges and the Nuns' farm. These consisted of: 1 . A dam and embankment at top of ranges, 22 feet long, 20 feet wide and 7 feet deep, with flume and flood gate, the flume being 20 feet long, 2 feet wide, and 3 feet deep; 2. A long enbankment, about 350 feet, average width 5' .6", average depth 6' .6", with one flume and gate, the flume being 20 feet long, I' .6''x2'; 3. A second enbankment, length 273 feet, average depth 4 feet, average width 5 feet, with flume and fl«v)d gate, the flume 14 feet long, I' .4" X 1' .9"; „ ,„ 4. A dam and bank at back of Butts 18 feet long, 10 feet wide, 6 ft. deep, size of flumelSft, 1' .10"xl' .16"; 6. A dam in front of Butte, 12 feet long, 7 feet wide, 7 feet deep, with flume and gate, size offlume 13 feet, 1' x I' .2" ; 6. A bank and dam north of Rifle ranges, 12 feet long, 12 feet wide, 4 feet deep, with flume 13 feet long I' .4" x 1' .5" ; 7. A dam and embankments, on the Nuns farm, 24 feet long, 12 feet broad, 6 feet deep, with flume 21 feet long V x 2' .6" ; 8. An embankment and dam, also on the Nuns' larm, 50 feet long, 8 feet wide, 3 feet high, with flume and gate ; flume 12 ft. long \VxVL' The work was not given out by contract, but was done under the immediate super- inteftdence of Mr. Richard McKeown, who carried it out to the entire satisfaction of the Committee. The same remark is applicable to Mr. James Wright, engineer, who had charge of the machinery. The Committee had the advantage of the co-operation of Messrs. Walter Shaiily,ifl.P., C.B., John Kennedy, Harbor Engineer, Louis Lesage, Superintendent of the Mont- real Water Works, P. W. St. George, City Surveyor. F. B. Lavall6e, Deputy Citv Surveyor, also took an interest in the work and gave very valuable assistance. Ill \ w Inntead of IeMin({ or hiring pumping tna- ehinery, an had been originallv intended, your CommiUee found it would W more in the city's interest to purchase the pumps re> ()uired. Accordingly thev procured fVom the Morris Machine work, ISaldwinsville, N.Y., five Heald and Siwo No. 12 centrifujfal vertical pumps, each capable of disoharfting 10,600 gallons per minute. Three of these were placed in No. 1 cut at Gommissionrrs street, and the two others in No. 2, Mill street The total capacity of the five beinjr 76,000,- 000 gallons per day of 24 hours. Powerful hand pumps of modern pattern were suffi- cient for stations 3, 4 and 6, and a 6* rotary •team pump, owned by the Road Departnu at, was used in No. 6. The Grand Trunk Railway Com pa sy gavi, your Committee most valuaole assiPtonce by granting the use of three locom^tives, <»n which considerable alterations were i.->Rd«, to flt them for driving the larse puropM on Commissioners and Mill streets. They answereil the purpose admirably, and your Committee would recommend that, on ex> amination and approval by an expert, they be purchased by the city, and retained for similar work in fnture years. They can be procured for |1260 each, aa they stand at present, including all charges for the altera- tions made to adapt them for this work. The Committee cooaider that it would be impossible to get the same amount of motive power in any other way for a like sum, and fhey therefore consider that the acceptance of the terms iiamed in the letter to Mr. Wallis, mechanical superintendent O.Tit., which is submitted herewith, would be most advantageous to the city. In the event of the Council not purchasing these locouto- tives, the cost of their alteration, and their return to the G. T. R. works, will have to be defrayed by the cky. Whatever plans or schemes may ultimate- ly be adopted for the prevention of floods, it is quite evident that, so long as the water in the river does not rise higher than the revet- ment wall, the pumping of the sewage iw- nishes an effectual and comparatively in- expensive method of keeping the cellars and streets free from inundation, and will doubt- less be continued in future years. The ex- periment of this year, notwitbataiiding numerous difficulties and drawbacks, proved to \ye quite as satisfaotory as the most san- guine could desire. There is anvpl* evidence to show that for 8 or 10 days previous to the 17th of April, the water in the river kept StrBully riSiQg, SSu attained a Icrri whicit, but for the oammiDg and pumping of the sewers, would have flooded nearly all the cellars in St Paul, Commisaioners and the lower portions of many other streets, is the business part of the city, as well as in St Ann's wajd. Seocca of peoplt taaiify that ia former years, with the wrater in the river at a similar height, they had been inundated to a depth of several feet, whilst this year, up to the day above named, they were perfectly dry. On that day, however, the water x)ver- flowed the river banks and revetment wall in a disastrous (" ^liige, having risen to the unprecedented lieigTit of 44 feet 4 inches above the bottom sill of the lower look of the old Lachine Canal (that he\u\t the datum line adopted by the Harbour Board for that purpoee). In the great tlootl of 18f)I, tne depth of water was 41 feet 8 inches, so that this year exceeded 18fil by 2 feet 8 inches. Front SatiinJay, the 17th, nt noon, until TucHday the 28th, when the ice jam in the river gave way, punipint; operations were of course suspended. But as soon as the water commence'l to recede, work was again resumed, and within 2 or .3 hours, the sluice gates in all the flumes were opened, and the pumps were kept in operation until .he end of the week. ^ The expenditure already made in connec- tion with this amounts to about (8,000. and your committee estimate that it will require between $4,000 and $5,000 to cover outstanding accounts and the work yet to le done. Should the Council determine to purchase the O. T. R. locomotives, $3,750 will require to be added. An account of this expenditure, and also a statement or in*'3ntory of the plant now in possession of your Con^mittee is appended to this report The value of the machinery and plant on hand, exclusive of the locomotives, is tie- tween $3,000 to $4,000, all of which will be available for use in future yeartf. Workmen are at present engaged in reetoc* ing the Rifle Ranges and Nun's farm,to their former condition. The work will be com- pleted in a very fiew days> The cut at Mill St. station was found to be in a most unsuitable place,the soil there being a sort of qnicksitnd, and there being a num- ber of oM flumes and pipes at that particu- lar spot. There ia a much better location, 160 feet higher up the street, which is clear of all obstructions, and which will have to be adopted in future years. The pumps^ framing, etc., were therefore taken up, and the brick work of the drain restored. Through the kindness oCMr. Conway, the pumps and other plant used at that station, have been stored ia the goyernroeut yard attjoining. The pump» at Commissioners street sta- tion have not been removed. Everything is left ^nst as it was after the flood, awaiung the uecisioa of the Council as to what action is to b« taken on the recommendations of th« City Surveyor, which accompany this re- port. Something must be done immediately however, to remove the large bank of earth, so that the people in the neighborhood may not hfty* ca«se of complaint in the riv«r at 1 inundated to this year, up were perffctty lie water ^over- 3vetiuent wall I riaen to the eet 4 inchen lower lock of lat beiiiiT the [arbour Boant freal tlood of feet 8 inches^ n by 2 feet 8 1 7th, nt noon, the ice jam in ni; operations iut as 800U an de, work was r 3 hour", the were opened, peration until de in connee- about |8,000. e that it will 6,000 to cover work yet to be determine to otives, $3,750 .n account of Btateiuent or poH8e88ion of 9 this report, and plant on lotives, Ih tie- which will be re. aged in restot* i farm,to their will be com- mas found to he oil there being being a nuin- that particn- itter location, vhioh isclesr will have to The punnpe ^f them, and $300 for removing them back to the Com- pany's yardH, or $2,000 in all, which would be practically loet to the City.
