Edison was the one who invented this system of taking in succession very
rapidly a great number of pictures of moving objects. We hope that Dr.
Elmendorf will be successful, for we will then be able to see these
interesting scenes; and if by a clever use of the phonograph or
graphophone he can record the sound of the guns, we may not only see,
but hear, the battles.

In THE GREAT ROUND WORLD last year we described experiments that were
being made with kites by Mr. W. E. Eddy, of Bayonne, N. J., who has been
largely instrumental in promoting interest in scientific kite-flying.
Kites have been made of such power as to carry a heavy cable from one
point to another over some obstruction, or to lift a man some distance
from the ground for the purpose of observation. It is now planned to
make use of the kites for offensive and defensive purposes in connection
with the invasion of Cuba. These kites can be raised to an enormous
height and photographs taken of the country, or, if necessary, by a
clever device which slides on the string of the kite, dynamite can be
carried to a point over the enemies' camp or fortifications and dropped
into them.

It is also believed that the kite will be of great value for signalling
purposes, especially at night, as it will be possible to hoist electric
incandescent lamps to a great height above the earth and signal by
turning the light on or off in accordance with a settled code. Mr. Eddy
estimates that it will be possible to drop fifty pounds of dynamite at a
time from a distance a mile away; the plan is to send up these kites
from within the lines of the attacking force and drop the dynamite into
