The New York Herald of the 9th ult.
gives an account Of new invention for
military purposes from which we make the
following extract.


The scientific gentleman alluded to, Mr..
McCartey, who is now connected with the
navy yard, has invented new species Of
artillery, which will discharge thirty balls
in minute, or one every two seconds, for
hours together, in succession, and this by
mechanical power alone, without gunpow-
der. chemical substance, or any other pre-
paration. 1t is effected by merely putting
the balls into hopper and letting the ord
nance throw them out with immense mo-
mentum. at the rate Of one every two Sec
onds. On one occasion, Mr.. McCartey
exhibited the operation Of this invention in
the navy yard, before number Of naval
officers, who were all astonished by the
force and power exhibited, as well as by
the great simplicity ofihe machine. About
twelve 10 twenty pieces of solid timber
were united together, forming one com pact
body. Against this piece Of wooden breast
work, Mr. McCartey opened the battery
of his piece of ordnance, and in less than
ten minutes, the whole solid breastwork
was utterly demolished and shivered to
splinters, by the powerful and rapid sue
cession Of discharges upon it.
