"Hello! I didn't expect this!" cried the senator's son. "Why, a fellow can't see a hundred feet in any direction."
"What are the natives going to do now?" asked Dave of Captain Marshall, who had been awake for some time.
"Soko says they must rest and wait," answered the captain. "He cannot go ahead, for he knows not in what direction to steer."
"I've got a pocket compass!" cried Phil, bringing it forth. "How odd that I didn't think of it before."
The captain took the compass and showed it to the native who could speak English. He had seen such things before, and, after a short talk with the master of the Stormy Petrel, set the others to using the sweeps as before.
It was about ten o'clock of the forenoon that one of the natives, who was watching in the bow, uttered a short cry. At once those at the sweeps stopped pulling.
"What is it?" asked Captain Marshall, quickly.
"Big ship over dare!" announced Soko, a moment later.
