144 Hudson and Mohawk Rail Road. 4 
inches stroke. ‘To these is attached the apparatus for hauling ° 
the cars which will presently be noticed. _ 
The road then proceeds North Westerly up to the head of Lydius 
Street to strike which, it takes a curve of four thousand feet radius, and 
passes over two heavy and high embankments, and through some 
deep cuttings near the alms house. : ae 
From the head of Lydius Street, (where the travel at present ter- 
minates) it proceeds in'the same direction, crossing the heavy em 
- bankment, called the Buel viaduct, ascending a plane for about three 
miles, of one foot in two hundred and twenty five. Afterwards as- 
cending by two other planes at different points, and crossing severd 
waterways, upon enbankments it proceeds to the Schenectady sum 
mit. There are in all six principal embankments. 
About four miles from Schenectady, there is a curve in the road, 
(radius twenty three thousand feet) which with most people pass 
unnoticed. Just at the summit is a smaller curve with a radius of 
one thousand one hundred feet. Besides the plane last mentioned, 
there is another of three miles, where the ascent is one foot in two 
hundred and seventy, and another of one mile and a half, where itis 
one in four hundred and fifty feet. The descent from the Sehene 
tady summit, to the level of the Hudson is three hundred and thitly 
five fect. At this point, to which we have in imagination conduct 
our readers, a beautiful view is obtained of the Canal, the Mohawk 
river, and the ancient city of Schenectady. A double stationary engine 
is placed here, and may thus be described. In the cellar of a hous 
which is built on stone foundations across the road, and on the North 
side are placed the boilers. 'The steam is conducted into two hort 
zontal cylinders, firmly secured, of the size already mentioned. The 
_ Shackle bars are connected with an axis on the extremity of W 
isa crown wheel, working in another at right angles, on a shaft ple 
ced vertically. This vertical shaft carries at its upper end, which § 
near the surface of the road, and directly in its center, a larget W 
around the circumference of which the hauling ropes pass; and run o 
rollers placed at regular distances down the plane. ‘The plane over 
coines a height of one hundred and fifteen feet, with an inclination 
like that near the Hudson, and running down a heavy embankme 
strikes the canal about half a mile from the principal street in ~~ 
nectady, but the track is prolonged upon a level to within sixty rods 
the same.
