and unlocked for result occurred, it being
deeply penetrat ed or the left-hand side by
the two shots fired from the 6-inch gun,
and the shot in the center from the S-inch
gun; while the two shots on the right-hand
side from the 6-inch gun penetratel only to
the depth of . and 515 inches. respectively.
This would indicate lack of uniformity in
the temper, or the possibility of defect in
either Of the shells fired
The tests to-day have been pronounced on
all sides to be most wonderful, and are
proof of the great progress made in the
making of armor in the United States. The
guns used were the same as at the test of
October 81, a forty-caliber, six-inch gun,
and thirtv-fve caliber, S-inck gun. The
six-inch prof ectiles were also the same as
those used be fore, being made by Hotter,
in France.
One of the eight iach projectiles. was of
the Firth-Firminy make, the same as used
in the first trial, but as no more of this
make were on hand, the 9TH two were
Carpenter proiectiles, mad. by the Carpen-
ger Steel Company, of Reading, Pa. Four
six-inch projectiles were fired at each plate,
one at each corner, ami then ore eight-inch
proiectile at the center of the plate. The
pounds. The powder charge was 42.4
pounds of Dupont brown prismatic powder,
giving a striking velocity of 2,075 feet per
second.
Size and Weight OF the Projectiles.
The Firminv eight-inch proiectile weighed
210 pounds, and was fired with 741% pounds
Of powder giving striking velocity of
1,750 feet per second. The Carpenter eight
inch proiectiles weighed go pounds, and to
equalize the striking energy, the powder
charge was reduced to 7214 pounds, reduc-
ing the yelocity to LOO feet.
The first shot was fired at the upper left
hand corner of the high-carbon nickel-steel
plate, not Harveyized from Carnegie,
Phipps s. Co. The point of impact was
two feet from the left-hand edge, and two
feet from the top. The projectile rebounded
intact. The penetration was 12% inches.
A few small radial cracks were developed in
the burr around the shot hole The wood
backing could be seen through the shot hole
The second shot was at the corresponding
corner of the Harveyized low carbon nickel
steel plate from Carnegie, Phipps & Co
The projectile apparently uniniured, re-
mained in t.. plate with its base projecting
beyond the face, and its point 141I inches
deep in theplate and backing. Short radial
cracks appeared il the burr.
Shot No. was al the corresponding cor
ner of the high carbon nckel-steel Harvey
lied plate from the bethlehem Iron Works
Il rebounded badly broken, leaving a hole
u inches deep. Small pieces of the burr
were broken Oft
A Badly BrokenCp PrcjectiIe
Shot No. 4 was at the upper right hand
corner Of high carbon Carnegie plate. 1t
penetrated l0s4 inches. and rebounded
broker Up. Short radial cracks appeared
in the bur-.
The fifth shot was al the upper right hand
corner Of the Harveyized low-earbon Car
ne@ie plate. The shot was almost a dupli-
cafe Of the frst one fired at this plate, the
penetration being 142z inches, and the pro-
jectile remaining in the plate intact
The sixth shot was at the upper right
hand corner Of the high carbon Harvevized
plate from Bethlehem. The proiectile was
virtually smashed 20 small fragments on the
face Of the plates. The point was left stick
ing in the hole with o.: apparent penetra-
tinn OF but five inches.
Tic seventh shot was at the lower left
hard ccrner of the high-carbon Carnegie
plate. The rroiectile penetrated II inches,
and rehounded broken, leaving the wood
visible through the mole. \ crack, appar-
emily through TO the backing, extended
from the hole to the bottom of the plate.
Shot No. was al the lower left-hand
corner of the low-carbon Harv eyized Car
ncgie plate. The projectile penetrated 90
inches and reboundcd, shortened two inches.
The ninth shot was at the lower left-hand
corner % the high carbon Harveyized Beth
lehem plate. The penetration was 124
inches. Tie prc;ectile rebounded intact,
ard left eight lair-!ine cracks about the
shot hole.
Another One Not Quite the Best
TIC tenth shot was at the lower right
hand corner OF the high-carbon Carnegie
plate. The penetration was 11I5 inches,
ana the prcjeetile rebounded intact A
deep crack extended f-om the shot-hole
through the lower left-han6 hole to the lett
ed=c o! tie plate
Tne eleventh shot was at the lower right
