"Mor'n a capful, too," he said grimly.

Even as the two old salts exchanged glances the cloud seemed to grow, as if by magic, and by the time the awning was snugged home and lashed and everything had been hauled taut in preparation for the blow, the whole heavens were overcast with a sullen gray veil, and the sea began to rise with a low moaning sound that presaged what Ben Stubbs termed "a bad blow."

CHAPTER XVI.

IN DIRE PERIL.

"Get that thar dory aboard," was Ben's next order to the boys, who began to feel quite tired, what with their exertions and the oppressive weather. As he spoke, a livid streak of lightning tore across the overcast sky, followed by a long roll of thunder that made the boat vibrate.

"Come on, bear a hand, there's no time to lose," he insisted, "tumble aft there—tumble aft."

It was quite a task to get the dory aboard, even with the aid of the Bolo's stern davits. The sea was rising every minute and even when they had the "falls," as they are called, secured to the little dinghy, she threatened to stave either herself or the Bolo while she was being hoisted and lashed. At last, however, even that task was accomplished and the boys began to anticipate a rest. But the indefatigable Ben would not let them loaf, even then.

"I want her to set more by the stern," he said, "shift those gasolene cans aft here, and we will trim her down in good shape."

"You see," he explained to Frank, "when the sea gets real high she's going to lift her propeller out of the water if she isn't well down by the stern, and that would make the engine 'race,' and that we don't want it to do, as it is likely to put it out of business."

The boy nodded.
