IN a naval battle, the range is ob-
tained principally by men stationed
in the mast-tops, the readings of the
instruments being tele-
phoned down to the officers
in the plotting-room below
the warship's deck. Here
the instrument readings are
quickly transcribed into
terms of gun ranges and of
angles of horizontal deflec-
tion. :
These calculations are
then sent to the gunners
through speaking-tubes, al-
though telephones and nu-
meral indicators are often
used, to make sure that the
orders will be understood.
For, when the battle waxes
hottest, either a voice-tube
or a telephone is likely to be
swept away.
In big battles the gun that has but
one channel of communication stands
grave chances of being cut off from the
rest of the ship. Should that happen,
the gunners would have to depend
upon the gun's telescopic sights, and
there would be no checking
up of hits or misses by
the spotters in the mast-
tops.
Thus the means of com-
munication is the crux in the
modern method of pointing
and firing a battleship’
guns. In our Navy, voice-
tubes are generally pre-
ferred to electrical appara-
tus.
The speaking-tubes are
metallic pipes made air-
tight to conduct the sounds
efficiently. Nothing short
of a rupture or a large hole
torn in the tube by shell-
fire will impair its operation
to a dangerous extent.
