INDUSTRIAL INTELLIGENCE.

The yew tree seeds and leaves have
lately been made of use in the shape Of
an oily product called taxine, which
solidifies on cooling and possesses con-
siderable narcotic properties.
A PAPER on the electric railway In
Scribner's Magazine expresses the be-
lief that ten years hence "there will
not be a single horse railway in opera
ton, ct least in our own country"
IN making charcoal for gunpowder it
is always kept for three or four days in
air-tight cylinders before picking over,
and ten days to fortnight before 1t Is
ground. This, it is said. is done to coun-
teract the well-known tendency to fire
II exposed too soon after it is made.
THAT the horse-breeding industry is
being seriously disturbed by the rapid
development Of electricity as q motive
power Is evident. The Indications now
are that within another three years
there will not be a horse car in active
service in any of the cities in this coun-

TIE production Of educated workers
for The HUMOROUS branches Of electrical
engineering IN this country is rapidly
increakns. The Register Of Cornell
University for the curr1Rt year furnish.

trical engineering Department Is now
170, tho senior class claiming "a, and the
other clssses In order containing 50, 81
and go students. Besides these 10 stu
dents are pursuing post graduate studies
in the same department..
ONE OF the most interesting things In
connection With tho growth and devel'
opment Of the electric light and power
business is its influence upon allied in
dustries, the demand for certain classes
OF material being in some cases greater
than has ever before arisen. This is
we'll illustrated by an order which has

inches wide, and the other 4s inches IL
width and Of much greater length
These will require the hides of more
than 600 head Of cattle.
