The centrifugal gun, according %

partment, is capable Of firing about
1000 balls minute. When It IL de-

flow Of balls into the breech-block.
Then the motor is stopped. Other
wise the balls would continue to be
elected at a decreasing range 40 the
motor slowed down.
The hopper is 4 patented container
with revolving bottom fitted with
grooves. AS the machine gunner turns
crank or handle the balls are ground
one by one into tube which leads to
the breech-block. Instead Of grinding
them out by hand, the same power
that operates the gun may be utilized
to drive the mechanism Of the hop

AS now designed two men can carry
the machine and tripod, and two more
men can transport the batteries.
Fire control with our gun Is con-
slant" said Mr.. Moore. 'There Is no
smoke. noise or flash. Instead of q
600 men being exposed to enemy dre
and covering much ground and area,
less men than make up one squad
would be used in operating our gun.
and the fire control would come from
one central point. Distributing our
guns at certain intervals would cover
an enormous front line. The lack Of
fire or noise from our gun conceals
the position Of the same and prevents
the enemy from ascertaining its To-
cation"
1t is a well known fact that bullets
fired from gun held rigid will not
all strike in the same place. but will
show a lateral and vertical spread.
Mr.. Moore has figured that the lateral
spread Of ball from the centrifugal
gun is approximately FIVE feet for each
hundred feet that the ball travels, and
the vertical spread three feet for each
hundred feet. Thus, at distance Of
300 feet the centrifugal gun would
cover street Is feet wide for a dis
lance Of nine feet above the ground,
at the rate Of 1000 shots q minute.
thereby rendering anybody's chances
Of remaining alive in that area ex-
ceedingly slim. The territory that
could be covered by the gun without
aiming It increases CORRESPONDENCE %
the range is increased.
Major Moore explained that he felt
free to discuss the mechanism and
principles Of the gun because the re-
strictions placed upon him not to re-
veal or discuss any details connected
with the gun have recently been lifted
by the war department.
