flour mill The windmill, which is
thirty feet in diameter, is automatically
coupled to the dynamo on acquiring
sufficient speed. and the dynamo charges
a secondary battery, automatic devices
reducing the current when the speed is
too high.
The electric current is, it is said, in
successful use at the gun factory of st.
Etienne, France, for tempering springs
The latter consist of steel wire wound
spirallv. and current of 23 amperes at
A. volts is passed through. Rapid heat
ing results. and when the required tenn
perature has been reached the circuit is
broken and the springs fall into a
trough of water. One workman, it is
said, can temper :, 400 springs per day
by this method.
1t is announced that grading will
begin next month. near Edinburg, on
the Chicago & st. Louis air line electric
railway, and proceed toward St Louis
and Chicago. The principle objection
to this line being the danger from
grade highway and railway crossings
on account of the proposed great speed,
plans are now being drawn for twenty
bridges for the electric road over steam
railways, and to do away with the
grade crossings

1t has its own wagons for delivering
freight to and from the car at Sixth and
Market streets, at Arsenal street and at

The application of electric power to
the propelling of boats is receiving con-
siderable attention in this country at
present According to the Electrical
Review, a fleet of these boats is expect
ed to be in commission at the Worlds
fair in Chicago. In this matter Eng

of their American cousins. Electric
launches are in daily use on the Thames
Boston has magnificent body of water

On some of the islands, and just enough

have its fleet of electric launches?
