Less than a hundred feet from the enemy, Frank made out several forms forward.

"This is close enough," he whispered to Jack.

Jack shipped his oars and picked up his rifle. Frank did likewise.

"You get the one on the left; I'll take the one on the extreme right," said Frank. "Then get the one next your first man if you have time before he ducks, and I'll do the same."

"All right," said Jack. "Give the word when you're ready."

"Ready! Aim! Fire!" said Frank quietly.

Two sharp cracks broke the stillness of the night, followed almost instantly by two more.

When the lads lowered their rifles and gazed toward the foe, there was not a man in sight.

"Don't know whether we got them or they just ducked," said Frank. "We'll fire a couple of more shots, enough to make them take their light off The Hawk."

They did so, and a moment later their efforts were rewarded. The searchlight aboard the enemy, moved by an unseen hand, turned and swept the sea carefully.
