better at night than In the daytime; better
over wafer than over land, and better over
land with long waves than with short
waves, In tests made between Key West
and Colon, about 1860 miles, communica-
tons were carried on at night, but not in
the daytime, and the same results We're OBJ
tanned between Key West and San Juan
The longest distance over which ships have
communicated at night is 200 miles. The
present aim, he said. is reliable Communl-
cation, night or day, at 200 miles.
1T Is hoped that within the next year"
he said the system of coast stations will
be completed and each can communicate
with the adjacent one, so that there will
be a complete circuit around the country.
Each station will be connected with inland
places by telephone or telegraph. The trans
mission of time to ships, as done by the
Western Union Telegraph Company on
land, is expected by wireless on the sea"
Navy Yard Station.
Lieut. Commander L. A Kaiser, L. s. N,
gave description of the wireless telegraph
station al the Washington navy yard. Many
changes are being made there all the time
he said, and better results are being OBJ
tanned as the experiments continue. He
gave a description of the possibilities of
wireless telegraphy IN time of war. With
scout ships fitted with the apparatus, the
American feet and Washington could be
kept in touch with the whereabouts of the
enemy all the time, through messages sent
from the scout ships. The question of Sc
crecy is not serious, as a code can always
be used. The greatest danger is from in
reference from the enemy through the me-
dunn OF their wireless apparatus They
could keep sending out indefinite flashes,
which would break up other communfca-
lions. Efforts are being directed toward
tuning the Instruments so as to receive only
waves OF a certain length. If the enemy
should send out the same kind Of waves the
United States boats would change the tun-
ing of their instruments.
Maj Edgar Russell, u. S. A, told OF the
work done by the Signal Corps. The corps
made Its first experiments in 1899, and sent
messages from the War Department here
10 rort Myer, three miles. In 1902 the Sig
nal Corps used instruments in the maneu-
vers between the land and sea forces, and
a scout boat sent out to sea Tor twenty
or thirty miles from Fort Mansfield, where
a wireless station was established. gave
notice of the approach of the enemy's fleet.
Regarded as Best Test.
One of the best tests of the system has
been between st. Michael and Nome, IN
Alaska Communication was first estab-
lished there In 1904 and since then on ac-
count of the breaking of the cable, the
wireless has been carrying all messages
between those two points. Both commercial
and government business has been handled
over the 112 miles between the points, and
the service has been continuous. SIM
liar system IL now being established In the
Philippines.
ut is the hope of the corps" said Maj.
Russell, ito establish wireless systems in
all the artillery districts, connecting all the
forts or posts and to have communication
through the navy wireless stations from
each OF the districts to the fleet on the
ocean, so they may be kept in touch with
each other In time of war;
