which throws The "Surprise," and The man.
ner OF regulating the fuse Is also the same;
The first gun invented is TO be constructed
Of steel, and has two barrels, though only
one can be used at time. One is thirty ana
,be other forty inches in length. The rea'
son given for the construction OF tuis
little cannon is to show how easily
old ordnance discarded by the Gov
eminent can, with little expense, be

and become more durable gun. The little
cannon carries one pound ball; but its
virtue lies wholly in the accuracy oil the
shot aud the velocity with which 1t can be
fred, which is twenty times a minute. In
the cannon line there are three magazine
canpons, one OF which is called the "anni-
hilator.~ This is capable Of throwing l2O

THE "0ENERAL GRANT"
It is also a magazine cannon, and can be
fired forty-five times in minute. The third
piece Of this pattern is similar to that OF the
other two in mechanism, but lacking III lis
death-deaing qualities.
There are, besides these huge cannon,
number OF rifles, which for fast shooting
the like was never heard OF before. The
Doctor hes also projectle torpedo, which

war-yessel capable Of travelling at the rate
of thirty miles an hour, portable forts, ana,

to have all these instruments constructed
shortly, and to test them at Washington In
