the ground and the vibrations Of the ,
earth were communicated through the
medium of the confined air space. The
sounds then reached the listeners ear
via a rubber tube and an ordinary
stethoscope horn. By means of this
device the slightest vibrations of the
ground were rendered audible.
The geophone was used to detect
placed the weighted box on the floor of
an underground gallery or on solid
earth or rock. If the enemy we're bur-
rowing in the ground anywhere within
a distance of seventy-fve yards the
geophone would tell about it. In order
to enable the listener to know from
what direction the sounds came two
geophone boxes were provided, one con-
nected with each ear. By placing the
boxes small distance apart and then
moving them until the vibrations in
both ear horns were equalized the
listener could tell approximately in
what direction the enemy mining oper-
alton was located.
Geophones were used by both sides,
and so effective did they prove to be
that it is reported that they were
largely instrumental in stopping min
ing operations altogether. If an enemy
mine we're located by one of these de-
vices, counter mine could be started
at once and carried through, usually
with disastrous results to the hostile
miners.
AS our first step in the production of
geophones we adopted the French de-
vice; but later on we developed an in
strument with nearly one-third greater
range than the French geophone had.
This Improvement was developed by
the engineers and bureau specialists
at the Bureau of Standards in Wash
ington with money provided by the En-
gineering Department.
But by far the most important work
done by listening instruments was in
locating the positions of enemy gun
batteries. This was one scientific in
strument, at any rate, which the Ger
mans were never able to produce sue
cessfully for themselves. During the
final months Of the war more enemy
guns were located by listening instru-
ments than by any other means. An
American instrument with the army
spotted III German gun positions in
a single day by surface sound ranging.
This was the high American record set
in the war, but at all times our sound
detecting equipment had an uncanny
accuracy. Up to the end of the fight
ing. no way had been discovered to con-
ceal the location Of gun from sound
ranging instruments suitably placed
and properly operated.

the location of the enemy by sound
Since the unaided ear was not keen
enough to supply the desired informa-
ton, applied science came to the res
cue with the various devices embraced
in the general classification of sound
ranging equipment. The production Of
this equipment was under the direction
of the Engineering Department of the
army.
In three classes of military work we
needed hearing refined to the razor
edge. With keen enough ears we could
detect those subterranean operations of
the enemy known as mining; with ears
of that sort we could detect and locate
the positions of hostile cannon; and
still again we could employ such SEN
sitiveness of hearing to find in the
darkest sky at night the hostile raid
ing airplanc.

cumstances this elapsed time would
enable troops properly warned to seek
cover from the explosion of the pro-
Jectile. This development of sound
ranging apparatus and it's application
to the protection of personnel was
made possible by the far greater speed
with which shock vibrations travel
through dense medium like the earth
than through the usual sound-convcy-
ing medium, the atmosphere.

British type, and would operate under
more adverse weather conditions. The

GOUND ranging for the detection of
airplanes at night requires an
equipment which consists fundamen-
tally of sound gathering device and
listening mechanism, the combna-
ton enabling the observer to tell the
direction from which the sound is com
ing. When bombing plane approaches
at night the hum of the motor can be
heard at distance of from one to three
miles, or even more, depending upon
conditions. But the direction of this
sound is elusive to the unaided ear. as
any one can testify who has heard an
nirplane in broad daylight but could
rot locate it with his eyes. Before the
invention of aerial sound ranging the
scarchlights hunting for the hostile
airplane were obliged to sweep the sky
aimlessly in an endeavor to locate it
and the pilot of the plane could often
mannuvre to keep out of the light. But

passed when the long range rifles and
howitzers, with their marvellously accu-
rate sighting instruments, came into
existence. great proportion of our
industrial effort in the recent conflict
was devoted to the sole end that we
might aim our artillery accurately.
For instance, to this end almost ex-
clusively was devoted the enormous
production of aircraft material. The
observer in the airplane or balloon
trusted not to his eyes but to the finer
sight of the Photographic camera; and

This congress will he made up of

and help shape plan of action.
The government at Washington has

the committees created there which
have since been doing effective work.
The government is vitality interested
in know how the West thinks on re-

MANY ARKANSAS MEN
BACK FROM FRANCE
TO BE DISCHARGED

Camp Pike, Ark, Feb. Two
hundred and eighty-nine Arkansas
and Oklahoma men, and four from
Texas who served with the 331st in
fantry of the Ohio division arrived
here Tuesday from Camp Mills for
discharge. They were in charge of
Lieut.. Arthur Syne. The men disem-
barked from over seas on January
81, and Immediately after physical ex-
animation and going thru the "delous-
ing" plant were started for Camp
Pike. All probably will be discharg-
ed Monday The "delousing" treat
ment caused the uniforms which the
men received overseas to shrink con-
siderably, and many Of the boys are
reluctant to return home in such
clothing. They seem to feel that the
creased, shrunken uniforms ill befit
soldiers of the United States who are
to be welcomed in their home towns as
"conquering heroes" Consequently
Y. M. G. A. secretaries here have been
busy writing and sending for the boys

Few Saw Front.
But few of the men in the detach-
,ment were given opportunity to get
to the front, most of them just about
having completed their training when
the armistice was signed. They saw
service in different parts of France,
nevertheless, and are happy to be

u. S. IS POINT OF
SPECTATOR ATTACK

London, Feb. THE Spectator, al
ways one of the most friendly British
journals toward the United States
gives much space this week to criti-
cism OF American peace conference
policies. The Spectator finds 1t inn
possible to reconcile the system of ap-
pointing mandatory powers for the
German colonies with continuance
of the Monroe doctrine.
While approving American interven-
ton in Santo Domingo, and Haiti, the
newspaper asks if the United States is
going to ask retrospectively for a
mandate to be made there. "lf she
does not" the Spectator declares, "she
may aid suspicion that there is to
be one law for herself and another for
the rest of the world"
The Spectator hopes that the con-
ference will go further in the league
of nations than one insisting upon the
sanctity of International treaties. 1t

AN IDEA or THE WORK UNDER.
TAKEN MAY BE GAINED
FxOM THE FOLLOW1NG:

1.-THE end of the war brings us face
TO face with the task of preventing
the recurrence of catastrophe that
threatens the destruction of civilized
life. The one plan for doing this that
is receiving serious attention is the
establishment of League of Free
Nations.
"To business, which has seen the ac-
cumulations of a century consumed by
war, this plan holds out a prospect OF
stable international relations.
Labor, which has always borne the
principal burden of injustice and
strife, sees in the new order of justice
democracy and fellowship guaranteed
by league, their only refuge from
Bolshevism.
"Religion sees in the coming to-
gether of the nations the dawning of
the Kingdom of God.
'In the hearts of the mothers of a
generation that has paid to war a
toll of six millions sons, the vision
kindled hope that their choldren's
children may be spared the yet more
terrible sorrows of future wars.
"Men who risked their lives in the
battle for democracy find in league
of nations the sum of that for which
they fought and their comrades died.
"The proposal presents the most
important question of national policy
that as citizens we shall face in our
lifetime.
"In an hour when the creation of a
league is the principal subject for dis
cussion throughout the world, the So
ciety that was the pioneer in bringing
forward the project of league, owes
to the unconvinced an explanation of
what is proposed and to believers in a
league plan of action by which they
may help to secure one that will sue
coed and endure. Such is the double
purpose of this national congress in
nine sections to which the recipient
of this program is invited"
