The present position OF the country !"
respect TO lis foreign relations, naturally
directs the minds OF men towards the best
methods of putting The country in de-
iensiye situation, should any difficulty
grow on, of our relations towards any
foreign nation.
, During the last few months series oil
governments have been made with a new
invention. originated by Mr.. McCarIey,
a gentleman connected with the Navy
Yard a, Brooklyn. These experiments
were ordered By the government. and
witnessed by distinguished persons, and
were considered by .hem to be the most
novel, mos, original, and most startling,
| in n naval and military point oil view.
Commodore Stewart, it will he remem-
bcred, spoke OF project by when II
would be possible TO defend the whole
harbor of New York against the combln-
ed fleets OF all the powers al The world.
This may appear 10 be gasconade, but
from information which has been COM
manicated TO us, we are fully assured that
Commodore Stewards assertion is per-
lecly correct aud literal.
The scientific gentleman alluded to.
Mr.. McCar,ey, 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 success

or any other preparation. 1t is effected
by merely putting the balls into hop

out with immense momentum, at the rate
of Que every two seconds. On one &C.

Grafton 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 10y the great
simplicity of the machine. About twelve
to twenty pieces Of solid timber were uni
ted together, forming one compact body.
Against this piece OF wooden breasIwork,
Mr.. McCauey opened the battery Of his
piece OF ordnance, and IN less than ten
minutes, the whole solid breastwork was
utterly demolished and shivered to spin-
tiers, by the powerful and rapid success.

The simplicity OF this invention is one
of its most singular features. The secret
of il is known and recorded in history
from the time when David went forth
with sling and stones 10 combat the proud
Goliah. The principle of this new IN
veniion is simply modification OF HE
principle of the sling, applied TO mach'-
merry, in connection with tube or gun,
throwing out discharge of balls. The
machine is so constructed that on putting
in at one end The balls to be discharged,
a rotary motion is produced by means Of
a crank, and, by qAv rapid revolutions,
each ball receives, force and momentum
equal to that communicated by any guam.
tIly Of gunpowder. When this has been
done, slide starts and allows each ball
10 escape in succession from the chamber
into a tube, when they are thrown To al
most any distance, and with unerring
aim.
This ingenious invention. for which
patent has been taken out a, Washington,
and which ought to be purchased, is worth
$500, OCO-nay, even millions, 10 the
American Government, in the present crl-
sis Of lis affairs. By means of such ma
chimes, placed in the forts a. the Narrows,
capable Of discharging any number Of
balls OF any calibre, the whole combined
fleets of Europe could be torn in pieces
and annihllaled before they could reach
