Inventions the War Has Brought Out

caption 1: A Russian portable |
shield captured dur- |
ing a retreat and
now used by the
Germans. This
shield is made of
bullet-proof steel
and is admirably
designed to shelter |
five riflemen who
protect their |
trench-digging com- |
rades. The shelter |
may be taken to |
pieces in a very
short time and |
packed for trans-
portation in motor |
trucks |
caption 2: Listening to the sound of heavy guns with the
aid of a tin-can telephone receiver. A tin can,
suspended from a copper wire which is wound
about a pencil or penholder pressed against
the bone back of the ear, makes an excellent
instrument for detecting these sounds when
they cannot be heard otherwise
caption 3: An ingenious French
device for photograph -
ing the German posi-
tions. A special cam-
era is attached to a
kite, and when the
proper altitudeisreach-
ed, the photographs
are taken automatical-
ly. Occasionally the
kite is sent up from an
automobile, and is
towed to the desired
locations. One of the
interesting phases of
the war has been the
use of kites, even man-
carrying _ kites, in war
observations. A camera
can well take the place
of the man, especially in
a kite. The distance
from the ground can be
accurately estimated
by means of a theodo-
lite, the instrument
used by surveyors
