The outcast put his finger in the sand and traced a boat there.
"Ah, some kind of a craft on that island," guessed Dave. "Do you mean that? All right, I'll investigate."
Dave disrobed and swam to the island the man had pointed out.
He went all over it, and finally, among a thick clump of reeds, he came across a canoe. "Good!" cried Dave, feeling that he had been well rewarded for his care to the sufferer. "Why, it's a splendid little craft, paddles and all. The man must have brought it here and hidden it. He made for this spot when pursued."
When Dave got back to his patient with the canoe, the latter could not conceal his satisfaction and delight.
He motioned Dave to drag the canoe close up to him, which Dave did. He reached over into the bow and pulled out a bag made of skin.
This he handed to Dave with a free, hearty gesture, indicating that it was a gift.
Dave opened the bag. His pulses beat pretty high. His hopes grew immensely.
"More of the gold--the same gold, part of the treasure!" he exclaimed, with glowing eyes. "I was surely right. This man knows all about the treasure."
Dave looked at the outcast speculatively. He wondered how he could make him indicate more. He, too, began tracing in the sand. It was an intricate and laborious task. At the end of an hour Dave looked triumphant.
