dreadnoughts, will stand the pressure to which
they are subject when fired, but it is believed that
their life Is somewhere between 100 and 200 shots.
No one wishes to find out by experience what
their longevity is. Therefore, practice except
at the prescribed times may be done with the
big guns. Even at target practice they may be
fired only eighteen times through the entire prac-
tice period At the end of couple of years they
are refined, and in this way get new lease of
life.
"Ping-pong" practice as it is called and sub
calber practice have solved this difficulty Very
small guns shooting tiny bullets are attached to
the big guns In front Of these small guns swing
targets whose distance and motion be regu-
lated to correspond to the conditions under which
the turret's guns are fired. The aiming is done
by the movement of the large guns but the firing
Is done with the tiny, pistollike firearms. In this
way the manipulation of the guns in every respect
is like that in target practice, except the actual
