IN THE ELECTRICAL WORLD.

"A Maryland paper apostrophises
the electric railroad as 1.-THE golden
link that binds contiguous communi.
ties in the bonds of prosperity"
Among the courses at the Massa-
chusetts institute of Technology this
year, the greatest number of students
is found in that of electrical engineer
ing.
And now it is held by the courts
that the repairing of Edison incandes-
cent lamps by a Springfield electrical
concern is an infringement on the Edi-
son patents,
The Wisconsin Telephone Co. OPP
crates coin-actuated pay stations, and
is said to be suffering losses from petty
swindlers, who use the telephones by
inserting in the slot pieces of metal in
stead Of coins.
"A bill has been introduced into the
national house of representatives. pro-
viding for the construction of four gov.
crnment telegraph lines to connect the
city of Washington with the four sec.
tons of the country. The bill provides
an appropriation of S., 900, 900 for the
year 1894 to commence the work.
Lieut.. R. y. Jimenez, royal Span
ish navy, who has represented the
Thomson-Houston International Elec-
trio Co. in Brazil for the past two years,
has returned from that country, hav-
ing resigned his position. lie says
that, though the war in that country
interfered with all business, there is a
great future for the South and Central
American republics, and thinks that
American electrical manufactures will
find it a productive field to cultivate
1t appears that the Metropolitan
Traction Co. of New York, has offered
prize of $50, 900 for an actual working
system of motive power for street rail-
way cars demonstrated to be superior
or equal to the overhead trolley system.
1t is runored, says the Electrical
World that the actual object in view is
to obtain an underground electric sys-
tenn to replace the cable system now in
use by this company, and one that can
be esta blished in the cable conduits
without requiring any expensive modi-
| fication of these.
1.-THE great growth of public senti-
ment in favor of municipal electric
lighting plants" says the Electric
| World in its last issue, lis illustrated
in our electric light news department,
which for several months has been
teeming with announcements of mu-
nicipal lighting projects. Most of the
| towns and cities concerned are in the
West, where the idea of public owner.
ship seems to have carried everything
before it. 1t is too soon to draw any
conclusion as to the probable outcome,
but the reports thus far are distinctly
favorable toward municipal owner,

"A hand-power dynamo is the latest
phase which has been assumed by cleo
trio generators 1t is made by com
pany in Elbridge, N. Y. With it, we
are told, water may be decomposed, in
candescent lamps lighted, permanent
magnets charged, small motors driven
and n multitude of other interesting
experiments performed. With a pri
mary battery of from five to fifteer
cells, this dynamo may also be used al
a motor, thus furnishing power to rur
light machinery such as sewing-ma
chimes, fans, etc. The machine, it i!
said, was designed especially for tht
use of schools and students of electric
ity, and to Them it is claimed, it vii
prove of great use, since it illustrate
the theory of the modern dynamo
and follows in construction the detail:
found in large dynamos. Now, this
little machine, it would appear, ha!
the suggestion of possibility tina
might make it of great Importance
Might not larger form of it, tina
would give man good exercise in op
Grating it to produce current, be util
lied in connection with storage cells tt
accumulate electric energy sufficient t.
answer for lighting one or more room
through incandescent lamps? What
boon such machine would be TO tn
thousands who are bilious and dyspep
tic, for want of exercise and from
plethora of rich foodl The inventor o
such combined system of hand gen
orator and storage battery would d
more for public health than half tn
