various ships. Now the United States
Army Signal Corps is taking up wireless
telephony with long-distance installations.
with view TO determining the utility OF
the system for field service With the
instruments In use it is possible to com
municate in an ordinary conversational
tone for a distance of fifteen or twenty
miles. The army experiments are de-
signed especially to develop apparatus
that will combine compactness and light
ness.
Washington has an especial interest
in the army'S experiments with wireless
telephony by reason OF the fact that the
experiments and tests with this newest
fortune of war" are to be conducted in
the vicinity of the District Of Columbia,
with Fort Myer as the base of opera
tions 1t will be understood that the
government will, at least at the outset,
simply use the regulation commercial ap-
paratus for wireless telephony, and the
object of the experimental work In this
vicinity Is not so much to improve the
invention in a fundamental sense as to
adapt and perfect IL with reference to the
needs of the army. Our army officers
have long realized the possibilities OF the
wireless phone. but they have been obliged
to reject much of the apparatus that has
been offered for their use because Ii was
too compile ated or could not be depended
upon in adverse weather conditions. 1t
Is realized that when 1t is perfected the
wireless telephone will be a most valu-
able military asset and Will have many
advantages over wireless telegraph and
field telegraph and telephone outfits. ow-
ing to the wires required for the latter
and the long poles neceSSitated for the
wireless telegraph outfits. With the sound
waves of the wireless telephone travelling
through the earth or the water instead
of through the air as do the wireless
teegraphy sound waves, this part OF the
problem is obviously much simplified.
pins. which seem to get more and more
ornate every day, require even greater
attention. Old paste Is best cleaned
with dry prepared chalk. The same
as peridots or marQuisate. 1t is never
advisable to allow imitation stones to
become wet, while damp paste more
over, which in some cases would do no
harm to the gem itself, might loosen the
setting.
Oxidized silver is often left alone under
the mistaken notion that It's dullness Is
. natural and that the leaden film which
makes a buckle or hatpin look lusterless
is intentional on the part OF the wearer
There Is, however a distinct difference
between a false dizziness and the SOFTEN
ed color OF the silver when IL is clean,
and every now and then the oxidized
article should be rubbed with a rag dip
ped in solution of sulphate OF soda
after which it should be well rubbed
once more with a dry cloth and polished
with a perfectly clean chamois leather
Jet hardly by rights comes under the
heading Of precious or an imitation
stone. but II enters nevertheless so much
into the dress scheme of the day that its
limitations cannot be ignored for III has
many limitations If ii Is allowed to lose
its luster and become scratched and dull.
While its inky reflection. which is its
chief asset. turns to lifeless tone which
at once gives il an artificial appearance
The best remedy for timeworn jet trim
mings is to place them in equal parts of
vinegar and water, leaving them to soak
for quarter of an hour. and then TO
spread them on clean piece OF white
paper to dry Of themselves.
