In furtneT proof OF the Olton tpCopoN
ment that electricity. or rather the knowledge
Of electricity enjoyed by the people OF the
present age, Is still In its infancy. the WORK
recently carried on at the works OF the Bunaio
Union Furnace Company.stands prominent
Mr.. Frederick ID. Gatchell. chief electrician
OF the company. while working about tbe iur-
naces came TO notice the immense amount
OF work necessary to remove a salamanca

A short time ago when the Buffalo Union
Furnace Company's 81 furnace was blown
out for refining the salamander proved 10 DO
exceedingly hard 10 drill. The regular Tools
used for the purpose drilled 90 slowly that
valuable time was being lost. Mr.. uatchei
then suggested burning holes In the mass
by means OF an electric arc. His suggestion
was accepted, and tho matter placed In his
hands and be prepared an apparatus FOR dolng
the work. Mr.. Gatchell In describing the
undertaking said:
The apparatus consisted OF 90 b. a 3.
gauge cable for transmitting the power from
the dynamos to the carbon and furnace a
switch for d~isoonnecting the cable II any
thing should go wrong, a resistance OOH Oh
thirty feet Of No. 3 climax resistance wire.
Immersed in a barrel Of running water TO Keep
tho temperature ut a hxed point, the carbon
and holder. The carbon was made In CleVe-
land especially for this purpose, ana was
seventy-two inches long and two inches In
| diameter. The holder was made by our
| own man and was merely a frame OF IRON
| pipe 70 support the carbon, which was mounted
in an iron collar, which screwed TO al iron
pipe covered with rubber and fitted at the
back end with a candle for adjusting the
| carbon to position.
at required all the power OF the two dy-
namos that usually supply the electricity
for lighting the works and operating an
electric crane.
AT FIRST, when drilling holes for dynamite
in the salamander at b furnace. l used the
apparatus with no protection. and II was
extremely hot In the neighborhood. You
can see from the fact that we had a current
| of $50 amperes and a voltage OF 220. which
| represents in the neighborhood OF 100 horse
power. that the heat generated at the arc
was considerable. l connected the positive
side of the circuit to the furnace. using a
water pipe for q binding post ana the mega
connection was used because the current
flows from the positive side 70 the negative
and in passing through the. salamander,

and thus cut a hole much faster man II ,ne
