"Someone must remain in case the boats heave in sight," Neal replied in a positive tone, and the engineer said carelessly:

"I didn't think of that; but it'll be all right, I'll keep my eyes peeled," and he added to himself, "I wish he wasn't so certain about the others coming, an' then the disappointment wouldn't be quite so great."

Jake cautioned the boys against going very far from the beach because of the danger of getting lost in the forest, and as they disappeared among the underbrush he threw himself upon the ground, unable longer to fight against the despair which was rapidly overpowering him.

He understood perfectly well how great would be the danger in attempting to make their way through the wooded portion of the country at this season of the year, when fever germs lurked in every spot where stagnant water was to be found, and knew at the same time how extremely difficult it might be to find a place offering any more advantages than did the narrow strip of sand on which they had been thrown.

"It wouldn't be quite as bad if I knew where we are," he said to himself. "It can't be possible that we're on the coast of South America; but if that should prove to be the case we'd make a pretty mess of it by trying to cross."

Then came the thought that perhaps it would be better to travel up the coast, and as to the advisability of this he studied a long while without being able to arrive at any satisfactory conclusion.

Two hours were spent in this profitless speculation, and then the boys returned, bringing with them two large hoccos, birds looking not unlike wild turkeys.

"We shan't starve while such game as this is to be found," Neal cried triumphantly. "I believe we might have shot a dozen by staying longer; but there was no sense in doing so just for the sake of killing. It will be a hard job to eat all this meat before it spoils."

"How far in did you go?" Jake asked, rising to his feet quickly and trying to banish from his face the look of dejection, lest his companions should suspect how desperate he believed the situation to be.

"Not more than half a mile," Teddy replied.
