“Quick! In with you!” cried Jack, as he fairly pushed his two companions into the boat.

Then he gave it a hard shove and scrambled in himself.

At that moment, from behind, came the sound of running footsteps and a hoarse voice of command:

“Fire!”

There was a deafening crash and a hail of bullets sped over the little boat, for at the command fire Jack had cried out:

“Down!”

All three lay flat in the bottom of the boat, Jack, with one hand behind him, doing the steering from that position.

A second and a third hail of bullets from behind passed without harming them, and then no more came.

The three sat up in the boat.

“Pretty close, if you ask me,” said Jack.
