ARMY AND NAVY NOTES
Navy Department Testing !Gyro-
SC0pic Compass.
From The Tribune Bureau.I

Washington, June IS.
AN ELECTRICAL .DEyICE.-Extens've
experiments with costly apparatus known
as the gyroscopic compass. which is a
mechanism much more extensive than the
ordinary compass with which every one is
familiar, are about to be made by the
Navy Department This is an electrical
device which tends to improve the ac-
curacys of the compass and is an aid to
navigation. II has been purchased by the
Navy Department at an expense Of about
S12, 900 from the German makers and has
been installed on the scout cruiser Bir-
mingham, where 1t is under the observa-
ton of the experts who will report on the
advisability of extending its use. In that
event arrangements will be made with the
foreign inventors to have 1t built In this
country at probably one-fourth the cost OF
the initial, machine. The gyroscope over
comes the effect of metal ON the compass,
and one Of the possibilities which impress
the naval authorities is the doing away
with non-magnetic metal. which costs
about twenty times the ordinary steel en-
tering into the construction of ships OF war.
Then, too, the gyroscope will be Of i'm
mense value on submarines. where the
compass IS worthless and where the di-
rection of the boat depends largely on
observation with the aid Of the more or
less inadequate periscope. There are times
when the submarine is under he surface
when observation cannot be depended on
and when a compass would be of great use.
The practical possibilities of the device
have led to the experiment on board the
Birmingham, and results are awaited with
considerable interest by the officials OF the
,t~@
have to do with the navigation Of ships
and the important detail of adjusting the
compass.
