Some New Features in the Elec
trical Englnee. Ing Department
During the past threo years consid
erable improvement has been mado in
the general equipment of the electri
cal engineering department. This has
been quite necessary, since in no other
branch of engineering do machine
types or methods of construction so
quickly become antiquated or obso
loto. The close accord with the over
changing commercial practice, which
the department has Btriven to main
tain, has also dictated the lntroduc
tion of several now courses, requiring
much additional material in both h
brary and laboratory.
tance transmission of power have
brought into extensive use the two
and threo phase generator, induc
tion motor and rotary convertor. A
representative pair of the last nan
types of apparatus have been installed
in the senior laboratory, where they
offer excellent facility for advanced
experimental work. An accompany
lng view shows three senior students
in the act of making a test upon these
machines. The panoramic view of the
main dynamo laboratory, besides a
number of recent types and a few of
historical interest, shows also in the
foreground a special two and three
phase generator, lately built to ordoi

THE ENGINEERING LIBRARY.
There aro but few libraries tr
found anywhere In tho country better
provided with electrical engineer
literature than is that of this univer
sity. A recent investigation shows
that there are 464 bound volumes de
voted exclusively to electrical sub
Jects upon the shelves, while tho list of
electrical periodicals includes lli

Electric Co. From these various dy
namo machines electric currents of al
most any variety and of wide range in
quantity, pressure and frequency may
be easily derived. An excellent set
of Weston and other instruments are
also at hand with which to measure
them.

become luminous at night, mako each
particular hair stand on end as one
passes beneath them, and will even
cause miniature lightning (lashes to

Tho department has lately received
four largo transformers which can be
so coupled and operated as to produce
a pressure amounting to 50,000 vo.iS.

Tho rapid strides which havo been
made in tho art 6f electro-chemistry
and electro-metallurgy both in thib
country and abroad aro hardly rea

problem which has for Its object tho
conversion of tho latent energy of
coal directly into electric energy with
out tho Intervention of tho Bteam en
glno and the dynamo; so that all
electricians may ere long become per
force electro-chemical engineers. In
order that the students of this depart
ment need not leave the Institution
without proper training In the con
struction and management of these
special devices, tho course In electro
chemistry was last year introduced.
Excellent facilities havo accordingly
been provided for practical Instruction
along some of the above lines, and
much more equipment of the sort Is
projected.
