find it necessary to vary essentially from the experimental line, till I reached Hop brook, where, in passing on to the East mountain, a very formidable embankment became requisite, and as it could not be brought within limits, which could rationally be considered practicable, I extended the line 70 chains, by passing farther up the valley, and, by this means, succeeded in making a much better profile, ascending to Green Water pond, without exceeding 80 feet per mile.

The space between Green Water pond, and the Otis summit, which was run by Mr. Barton, presents very favorable ground-the line being direct, and not exceeding in grade, 25 feet per mile. After leaving this summit, in Otis swamp, it appeared possible to find a pretty direct line, if by any means practicable ground could be kept upon, through the valley of the Little Westfield river. My line was very encouraging, till I had descended two miles into the the ravine, through which the main stream passes. A dotted line in blue indicates this route, which however, I was forced to abandon. For, although I found myself right in conjecturing, that by bridging the stream frequently, very good ground would be attainable, the courses round certain rocky points could not be brought within admissible limits, without the most enormous expenditures. I returned, therefore, 8 miles, on my line, and following the side hill near Peeble's brook, I pursued the line marked on the map, taking all possible advantage, in crossing this stream, as well as the one above Bates' Tannery, where a deep ravine divides the hills. The soil in this vicinity being a fine gravel, intermixed with a large proportion of sand, the depth of these fillings are not very serious obstacles. After passing Elihu Stow's, the most difficult part of my route presented itself, and I was doubtful at one time, whether I could reach Westfield plains, without exceeding 80 feet per mile. My first attempt was by the Flat lot, and Reuben Noble's, and after again running, fruitlessly, four miles, I found the point of Sodom mountain impracticable, at so great an elevation, and could I have passed round this point, my grade was directly in all the ledges, on the east side. I returned, in consequence, to Flat lot, extending my line farther down the Little River valley, and succeeded in avoiding all these difficulties, and the increased distance bringing me 80 feet lower, I was enabled to reach the plains,

when less than half the distance had been passed on the east side of the mountain before referred to; all these circumstances have tended to lengthen the south route, and increase the curvatures; the distance from New York state line, to the intersection of Mr. Williams' line, with which I have connected the present survey, is 54.018 miles, and the whole distance to Connecticut iver, 62.387 miles. The deepest cut is 64 feet, gradually diminishing to 50 feet in the space of 400 feet. At Cobble gap, the grade runs for a short distance 85 feet below the surface of the rock, consequently a tunnel for 4 chains is preferable to an open cut. Had the line been carried through the gap, the cutting would not have exceeded 50 feet, but the line would have been thrown, in that case, by a sharp curve, to the edge of a precipice, which is now avoided.

The ravine at Stow's brook is 100 feet deep, diminishing, however, in the distance of 2 chains, to 60 feet. There is also a ravine in Lee, formed by Green Water brook, 110 feet below grade. This extreme depth extends only 50 links, and at 5 chains is reduced to 50 feet. In carrying forward the survey, I have been particular to take numerous cross sections, and though in a final location, it might be expedient to vary the line, the quantities estimated would not essentially differ. In rock cuttings and other bad places, I have kept in view this consideration, always making ample allowances. There are but 5 large bridges on the route three of 100 feet span, across the Housatonic river, and one of 40 feet, across Munn's brook. An examination of the map sand profiles, in reference to this statement, will give a tolerably correct idea of the general character of the route; and it will be seen at once how extremely difficult it has been to accomplish the object of the survey, without transgressing those rules, on which the essential value of Rail Roads depends. In running the various lines you have directed, I have never omitted to consider thoroughly, every possible mode by which advantage could be taken of the ground. And I feel confident in the assertion, that the whole space, on which we have bestowed so much labor, has been most scrupulously, and critically examined.
