more than half the recent discoveries
have been made known to the public.
1t is supposed that everything which has
merit can find market in New York
Yet as fact this is not always the case
The invention of Nikolo Tesla, Hum
garian, is a fact in point. He succeeded
in producing an electrical motor which
can be actually run by the refuse current
now lost in the alternating system OF
electric lighting. Tesla worked on this
motor for many years in this city and
after seing his idea put into practical
operation prepared the proper models
and went to Pittsburg, Pa. There he ex-
hibited his designs and plans to large
firm, the members OF which with char
acteristic shrewdness bought the patent
from Tesla, paying him good price for
it. Since then Tesla has remained in.

his invention. He deserves all tile credit

electricians claimed was impracticable
and unreasonable machine that will
supersede the make and break current
motors now in use.

ances, it is expensive?" he was recently
asked.
"There YOU are entirely mistaken. Its
simplicity and cheapness are remarkable.
Any number Of them with great capacity
to do work can be attached to an elec-
tric-light line if the dynamos are large
enough. With two simple wires con-

money and labor. The process is like
using the steam from an engine after it
has passed through a cylinder"
" Is the motor bulky or heavy?"
On the contrary, it is the opposite.
The motor occupies very small space.
It size depends upon the number OF
horsepower. One as large as an ordin-
airy telephone box has the power of one
horse. \ tive-horse power machine
weighs about $50 pounds. This is a great
feature as compared with the make and
break motors, which are cumbersome.
and almost as bulky as steam engine. y
How is the motor fOrmed?"
Each motor consists of a number Of
circular discs, one-sixteenth of an inch
thick, punched and fastened together in
a series OF bolts, which, with eight coils
of wire, and an armature running
through the cylinder of iron plate com
prises the entire machine. Their mo-
ton is noiseless. In this they are unlike
the machine with commutaiors and
brushes 1t is believed to be capable of
I 900 revolutions minute, but by tnrn-
ing switch i short distance the speed
can be cut down to three or four revoln-
tons minute. 1t is so easily applied
that any Business having the ordinary
electric hght wires running into the
and requiring motive power ~
any gwen capacity, can use, instead OF a
steam engine, one OF these motors by
simply connecting it with the incaRdes-
cent light line. y

That is another feature of its ,,saf,I-
ness. 1t Is understood that these motors
