In the next few years the two factors which have made
the present development of the submarine possible, reached
the period where they were become of some practicable
value. These factors are the automobile torpedo and
the electric storage battery. The automobile torpedo
furnished the submarine with a weapon with which it
could make an attack upon another vessel without dis-
astrous results to itself and in fact afforded a means of
reaching the ship attacked which lack of speed on the part

The storage battery effected the first satisfactory means of
propelling the vessel under water.
After the completion of the Fenian Ram Holland con-

accorded the credit for bringing it to its present day state
of practical value. He constructed four or five experi-
