engineering is illustrated by a fine collection of steam engines, gas
and vapor engines, water-wheels and other motors, models and draw
ings of every standard or historical form of prime mover, or parts of
machines, and of completed machinery.
The collections of the Department of Drawing and Art include a
large variety of studies of natural and conventional forms, shaded and
in outline, geometrical models, casts and illustrations of historical
ornament, and remarkably fine collections of casts,
other art work.

The workshops are supplied with every needed kind of machine or
tool, including lathes, and hand and bench tools sufficient to meet
the wants of two hundred students of the first year, in wood-working ;
in the foundry and forge, all needed tools for a class of over one hun
dred and fifty in the second year ; in the machine shop, machine tools
from the best builders, and a great variety of special and hand tools,
which are sufficient for a class of one hundred and fifty in the third
year, and as many seniors and graduate students.

of the various standard types for testing the strength of metals, in
cluding machines of 50, 100, and 150 tons capacity ; and one 60,000
and one 200,000 pound Emery machine, of extraordinary accuracy and
delicacy. Sixteen steam-engines, nine air, oil, and gas engines, four

ard pressure guages and an equally numerous collection of steam engine
indicators,
together with other apparatus and instruments of precis
ion employed by the engineer in such researches as he is,
in practice,
called upon to make, are collected here. A large hydraulic "plant"
is employed for experimental purposes and for research. All the mo
tors of the University, and its boilers, amounting to 1000 horse-power,
are available for test trials. The steam-engines are set up, with the
heavy lighting dynamos, adjacent to the boilers ; among them a 200
