“That will do, Silas,” broke in Mr. Dancer, “take Jupe and bring that ammunition at once.”

A few minutes later Silas and Jupe had brought the ammunition for the submarine gun from the steel-walled magazine in which it was kept. Naturally, steam being the driving power for the projectile, there was no powder necessary. In fact, the explosive bullet used looked much like the missile hurled from a four-inch, quick-firing gun.

It was highly polished, and at its extremity had a sort of mushroom-shaped tip. This was the “bow,” so to speak, of this submarine death craft. It was made broad so that it was not likely to miss anything at which it was aimed. The idea of the projectile was that as soon as it struck an object the mushroom-shaped tip drove down on a mercurial cap, which exploded the charge of high explosive when it detonated.
