“Well, old lady,” challenged the leader, gruffly. “What are you looking at?”

“I just saw a head over the top of that deckhouse,” the woman said, sharply.

The captain groaned aloud. He had been so interested in the proceedings that he had raised himself up higher than he had intended, and the top of his captain’s hat had protruded over the edge of the deckhouse. The old lady had seen it against the faint light of the sky.

“What!” shouted Benito, whirling around.

Don and Jim held their breath, but the captain saw that the time for action had come. Slapping them sharply with either hand on the arms he leaped around the deckhouse.

“Up and at ’em, mates,” he roared. “Give ’em all you’ve got!”

Alone, he charged across the deck at the three men, and the boys lost a precious second in gathering their wits. But when they did awaken to the situation in hand they ran around the shelter and raced after the captain. The three outlaws, seeing one man, had intended to stand their ground, but when they saw the two boys loom up out of the darkness they sprang into action in their turn.

“Down the hatch!” roared the leader. The old lady, with surprising agility for one so old, had gotten out of the way and disappeared from sight. Marcy hurtled through the opening and jumped into the hold. Frank followed and Benito was halfway through when the aroused captain caught him by the coat tail.

“Not so fast, my friend!” panted the captain. “I have a little business with you!”

For a brief second Benito was in a bad fix, but his companions below seized his legs and pulled hard. The tail of his coat ripped off, the captain staggered back, and Benito thudded to the floor of the hold. Before Jim, who was foremost, could reach the companionway, the door was slid shut and a bolt slipped into place.
