The llStening-in service of the signal
corps of the army is one of its inter-
! esting activities. Information of the
enemy and his movements is always Of
use, and sometimes of great impor-
lance.
The signal corps operates numerous
listening-in stations close to or within
the enemy's lines, at which, by means
Of devices recently perfected, it is able
not only to intercept any radio mes
| sage but also to determine accurately
the location of the radio instrument
which transmits 1t. This information
as to location is transmitted to the
artillery, which proceeds to put the
| radio station out of business.
German telephone wires have been
made to divulge their secrets, though
such wires are we'll within German ter
ritory where it is impossible to tap
their lines. This is accomplished by
one of the most ingenious instruments
that has been produced. BY means of
1t our signal corps man can sit in his
dugout on the front line with re-
ceiver to his ear and hear any tele-
| phone message wen within the enemy
territory, even though several thou
sand Huns may intervene between him
and the nearest point to the telephone
| wires being used by the enemy.
The signal service of the army came
into existence with development Of the
telegraph during the Civil war, and
was expanded greatly in the Spanish
American war. 1t was then mounted
organization, mobile as cavalry, and
used largely to serve the needs Of the
| cavalry. 1t developed practically a
perfect system for open warfare.
A new system had to be originated
for trench warfare and experts began
the study of this problem and the use
Of telephone and telegraph lines and
the radio as soon as the present war
started. Signal corps men were among
the first units sent to France after
the United States entered the war.
The French system Of signaling has
been adopted in part, but with many
| purely American innovations. The
whole fighting area within ten miles Of
the front lines is a mass of lines Of
Information. There is the wire net, or
telegraph and telephone; the radio;
the visual, or searchlight and fire.
| works, and the messengers, runners
and motorcyclists.
Plans for the student army training
corps have been changed by the war
department to conform to the lowered
| draft ages. The war department will
utilize the plant, equipment and organ
| tzation of the colleges to maintain
reservoir of officer material for train
Ing as officers and technical experts
from which it will be possible to meet
! the enlarged needs Of the various
| branches of the service.
The length of time during which
| men will be trained in the colleges will
depend on the needs of the service. As
fast as one group Of trained men Is
drawn from the colleges into the serv-
Ice their places will be taken by a
| new quota obtained by voluntary in
| duction or through the draft. In this
way the educational facilities of the
country will be used to maintain
constant supply of men who are
trained to meet the needs of the army.
Under the regulations selected young
men who are physically fit for mill
7 tary service, who are eighteen years
| Of age or over, and who have had
grammar school education may be In
| Quoted as volunteers into the army and
enter upon a course of special train
Ing. Those who have had only a gram
| mar school education will enter ordi-
narily special training detachments to
be trained along mechanical lines OF
military training. Those who prove
| In the course Of their mechanical train
ing that they are officer material may
| be transferred to a unit In one of the
| colleges to be prepared to enter a cen
trail officers training camp.
Young men who have had high
school education will be allowed to en-
ter the college for more advanced
| training as officers and as technical
| experts of various kinds, according to
their experience and abilities. Those
who show promise under this training
will be kept in college until qualified
| to enter an officer training camptOr be
sent directly into the service asitech-
meal experts; those who do not show
promise under the training WI be
sent either to noncommissioned Off
GERS schools, to the nearest depotlbrl-
gade or to detaehments where men are
trained according to their technical or
mechanical abilities.
