“I guess the best thing we can do is to go back to the boat,” said Dave. “We can’t discover much in this darkness. We can start out again early in the morning.”

“All right, back to the boat it is,” and the pair set out on the return along the sandy shore.

“I see a light!” cried Dave, after about half the distance to where the rowboat had been left was covered. And he pointed to a spot inland, among the trees.

“Maybe it’s a camp of some sort,” replied Roger. “It seems to be quite a distance away.”

“Shall we go and see what it is?”

“Hadn’t we better get the others first, Dave?”

“All right, if you think best.”

So they continued on the way to where the rowboat had been left. They came up to find that Captain Sanders and Phil had not yet returned. Smiley was snoring on the sand, while Billy Dill sat near by on guard.

“Find anybody?” queried the old tar, eagerly.

“We found one of the caves, and we saw a light at a distance,” answered Dave. “We want to investigate that light, as soon as the others get back.”
