IN THE ELECTRICAL WORLD.

"A recently OeS1gneO l0caOOeSccuV
electric lamp supported by springs Is in
tended for use in carriages and other
vehicles. Current il To be supplied
from a storage battery carried under
the seat or in any convenient place.
1t is interesting to note, in connec'
ton with recent experiments in high
potential discharges Of great frequency
made by Thomson and Tesla, where the
use of oil as an insulatOr has proved SO
efficient, that the employment of oil As
an insulator IS not patentab!c, and il,
therefore, free to everybody. -r.
1t is stated that the Omnibus Il
Tramway Co, Of Rome, Italy, has re-
Gently made experiments with an nc.
cumulator car fitted with motors, bat
teries. etc., supplied by the Ocrlikon
engineering works. When fully charged
the cells are said to be capable Of yield
ing energy to propel the car % miles. so
that it is only necessary to rcchargc

A large -four mill is now being
erected in st. Paul, Minn., which will
be operated entirely ty electricity, the
power for generating the current being
furnished by the water in the falls of
the Mississippi. II the experiment
proves to he as successful rs anticipated,
all the larger mills of st. Paul and Min
neapolis will hereafter use electricity as
q motive power.
An electrical workman of Berlin
was recently poisoned in a very peculiar
manner, which il will bc well for elcc-
tuicians to note. In testing his cells, To
see il current was flowing. he was in
the habit of putting the two ends of the
wires in his mouth, and the soluble
salts of copper produced eventually
caused his death. The galvanometer is
now substituted in that workshop for
this rough and ready test, which evil

One Of the best evidences Of progrc
in the development Of electric railways,
says the Electrical Review, is the fact
that very few trolley roads have been
reported the past winter rs beieg de-
laycd by snow storms. Although the
number of electric railways in opera
ton is greater than ever before, delays
are fewer, and service is better than at
any previous time. This is due not only
to the apparatus itself. but to the excel
lent management which now obtains in
every electrical railway company in the
country.

and the service is said to be proving
very satisfactory. The company has re-
Gently increased the number of these
cars to six. These arc doing regular
duty. and are watched with more than
ordinary interest. While the expense Of
running the system has not been made
| known. the question of its mechanical
and electrical feasibility is gradually be
! ing proved, and IL this form of electric
power is found to he q mechanical sue
cess, it is only fair to infer that means
will be found to make it a commercial
one.
1T is reported that for some time
past the engineers Of the Wisconsin
Central, the Illinois Central and the
Boston & Maine roads have made thor
ough Investigations into all the recently
patented appliances for electric power
and traction, and that orders have been
given which mean practically the intro
duction of electric power for the sub
urban traffic Of all these roads. Tho
Wisconsin Central, q road leased by tho
/ Northern Pacific. will be tho first to
test the system for its passenger traffic

very likely it will be applied to the en-
