Rear Admiral Howell has been con-
Quoting experiments for several years
to improve the vesuvius' guns and OBJ
yiate the difficulties which they pre-
sent. He believes that the only means
by which q safe, accurate and effective
gun can be secured is by embodying In
the projectile the two-fold character
of piece and projectile; that is, to have
1t receive impulse from forces residing
within itself. Upon these lines he has
worked until he has evolved a gun
which will speed a rocket containing
the explosive with the accuracy OF a
rife ball. He believed the rocket must
be made to revolve with the same TO
tary motion Of a steel projectile hurled
from an ordinary gun. To do this the
enormous pressure Of twenty tons to a
square inch would be required in an
ordinary gun. Such force would de-
tomato any mass Of high explosive at
the instant of discharge. He therefore
conceived the idea Of revolving both
the gun and the charge. The projectile,
consisting, In the 10-inch caliber, Of
one hundred pounds Of gun cotton, is
incased in a thin metal envelope, the
rear end OF which contains rocket COM
position and the head a percussion fuse
which is set in action by the force OF
impact This Is placed in the gun, and
when, by q mechanical contrivance. Il
has been spun up to twenty-five hun
dred revolutions per minute, friction
cap ignites the rocket composition,
and the banked up pressure at the base
starts the rocket. This, then, begins
its flight with a rotary motion corre-
spending to that of the gun. The fact
that this motion Is due to neither the
resistance of the atmosphere against
vanes nor to the escape of part OF the
prope1ling gas from a number Of vents,
gives 1t great range, velocity. and,
above all. perfect aecuracy-while the
absence Of any initial shock Of dis
charge renders II absolutely safe.
The heaviest war rocket fired from
the new Howell gun win weigh three
hundred pounds, the range will be
about three thousand yards, and its ac-
curaey almost equal to that OF a rife
prejectile. The piece. though IL can
not be called a high angle IRE gun, nor
one Of point-blank range. is between
the mortar and the rife. The new gun
can be used in both offensive and de-
fensIve operations, ashore or afloat-in
