ON THE 10 MILE SECTION OF THE LAKE ST, JOHN RAIlWAY NORTH-WARD OF ST. RAYMOND QUEBEC IMUNTEU BY GEORGE VINCENT -7 - :7-^^ 224, St. John Street Quebec, January Soth \HH4f To Hi^ Worshi}) the Mayor, The Aldermen and Councillors of the Co}'poratioH. Gentlemen, In compliance with your resolution of the 14th December last, calling on me to report on that poi'tion of the Lake St. John Railway which lies between the left bank of the St. Ann river at St. Raymond and lake Simon, a distance of some 10 miles; I visited the section of road under consideration on the 24th Dec. last, in company with his Worship the Mayor, Mr. Light, Govt. Engineer, Mr Cadman engineer in chief of the road, Mr. Scott the company's secretary, Mr. Cressman the contractor's active and efficient manager and a few other per- sons interested in the undertaking and in the welfare of Quebec. A slight fall of snow at the time of my inspection prevented the then examination of some of the minor features of the permanent way, such as the base of the rails, their mode of junction, the fish plates etc, the sleepers w^hich of 6" x 6" in size at the smaller end support, at two feet centres, the steel rails of which the weight is 56 lbs. to the yard. But I had occasion during two previous visits over this sec- tion of road, at a time when nothing prevented a minute ins- pection of the works, to satisfy myself that the quality of the materials and workmanship leaves nothing to be desired. The plan of the road, or its birds' eye view as it would be seen if looked down upon from above, indicates the more or less sinuous nature of its location as determined by the neces- sity of following in such a mountainous section of country, along the course of rivers, lakes and vallies with the view of reducing to a mininum the elevations and inequalities of the groundto be gone over. Oil this plan are seen i.i blue, a eulor siin^j^a'stive tliereot", ri- \ «'i*s, lakes and water courses ; in red, a full red line, that of the fiery ste«'d ; in yellow or burrit sienna, alst) a sug«restive eolor, the roads or lines of ordinary counnunication whieh in- tersect the railroad at ei^dit ditierent points in this length of suction and thereby subserve the purposes of local traffic : also the several curves, ])ends or deviations in the r()a«l whicli windin^^ now to the right, now in tlie opposite di- I'ection, make good the junctions between these sinuosities anove niean tide leVi'l jit (.^uelicc. of the h'Vels or hei^^lits to he «^iven to the road l»e(h ''ase or formation h'vel, wliieh is to receive the haliastin<;f, sh'epers and rails of tlie permanent way. Tlie.se ti;j;nres in reij ink refer to and corres- pond with the line of like coloi- inad an inipossihility with the means at the disposal of the company and have deprived us of it altojrether. Nevertheless and let us hope, in the near future, when the recjuirements of the trnfhe shall render it essential, tlu' road may l»e improved l»y lowcrinj^ it alon^ the heights and elevating it along or across tlui hollows or valleys as at St. Raymond where an additional ten feet of elevation over tlie St. Ann river would reduce by ahout oOO ft. the length of incline immediately to the North, thus lengtliening or extending the level leach beyond the bridge in a way to allow of a more prolonged, a better start, a greater accunnda- tion of velocity wheiewith to overcome thc^ rather steep grade of the incline in (juestion. The same remark apj)lies now more, now less to othei* ac- clivities, as to the North-wjml of River Rondeau where cer- tain advantaiies would accrue by raisin<>; the level of the hridge some 5 ft. or thereabouts. Side by side with these minoi- defects let me evideiice the fact that while many ev.oineers and surveyors had soujirht in vain for a railway to lake St. Jolni, a practicable route through the Laurcntians, M. Cadman, the engineer in chief of the road, under the pushing guidance of Mr. Light, has succeeded in making; out a way amon**' the mountains of which the sum- mit level is from oOO to 1000 ft. less elevj'ted than heretofore looked for from all the preceding reports (m the possibility of a railroad between Quebec and Lake St. John. I also note with satisfaction that the grades on this section are easier, or of lesser inclination than those on the sections previously reported, and tliat the locomotives used or to be us(k1 on the road will be of a capacity to liaul at least 80 cars over the steepest inclines. On a par with this question of grades, as a retarding factor, influencing the velocity of motion, is that, no less important, of curves of small radius ; but here again ^ve find that Mr. Light, Mr. Cadman have worked wonders with the restrained means at their disposal,turning now West, now East according- ly as the mountain spurs and peaks, so to say piled up in this section of the country, the ravines and hollows forced the en- gineers to turn an obstacle vvdiicli the pecuniary means at their disposal did not allow" of their getting through by an excava- tion out of all proportion or a no less expensive tunnel of like extent. NeverthelcoS I must note here as in the case of grades on this same section that the curves are less numerous, and of easier le l)y Order in Council of the lTeat velocity and under a less rapid transit, the friction of the wheels upon the rails will be diminished by so mueii : the y the heavy locomotives of the present day : these increased weights or loads I say, under a less rapid rate of transit will to a great extent compensate the advantage of the (picker and less heavy trains of freight which the more pressing and nuiltiple requirements of large centres of com- merce render necessary. Alluding now" to the less prominent features of the section of road reported on, a glance at the map or plan and profile w411 show the position, extent and construction, whether of w^ood, stone, iron or other material, of the seyeral bridges and culverts as called for by the contract and specifications, or as " too widely from theii' fathers' fire-sides, go seek a livelihood, if nothing more.
