The fastening ofthe cylinders made upon the frame
and upon stout cast iron bed plate, resting upon the
frame, and forming the bottom and fiat sides of the
smoke box. Without great weight this gives very

The running machinery Of the engines is very simple
and strong The rocker arms, lifting arms aud all other
parts OF the valve notion are OF wrought iron forged
The tires Of the driving wheels are exclusively of Low
moor iron, bent and welded at these The tires
accurately bent to the circular form TO fit the
wheels closely at every point without boring, thus
avoiding the expense Of boring and the loss Of iron
thereby.
There leading principles observed in the ad
mnisraon Of these works. which appear calculated to
ensure their highest efficiency, and the best quality in
their productions.
One the manufacture upon the spot only of the
engines but, as far as possible of the materials also
Of which they composed. All the forged work. tires
tubes springs brass and iron castings, chilled wheels
and other parts often purchased outside OF other works
are here made in the best and with the aid of
every fixture TO be found in the supplying
separately each of these items
Another is the greatest possible substitution Of
chinery for manual labor. In these work smaller pro-
portion Of the engaged in handwork than any
other similar establishment in the country
This circumstance is due 10 the fact that the tools
are adapted, In special manner to the execution of
each portion of the work. and that each class tools Is
specially appropriated To distinct portions of work
Another is the entire Independence of the different de-
partments OF the works from each other. Hardly any
two distinct branches OF labor carried together

utmost facility for all necessary communication be.

In the materials used for the engines wrought iron IL

The present depression in railroad operations has
PEELED these works, web all others Of similar occu

propretors rely, however, upon an ultimate improve
ment when their present works will become again fully
employed, and when they will also complete stil further
engagements and Improvements, already commenced
building, these works rely solely upon continual efforts
to sustain their past superiority.
