So George, baffled in this respect, had to give it up, and confess himself altogether at sea. But if Josh had simply gone and lost himself, then why had he not answered their shouts?

They had now been following the trail of the missing chum quite some time, and found themselves at a considerable distance from camp. Every now and then, apparently, Josh had made his way to the shore, to find out whether there were any flocks of birds in sight; but as he still kept moving on, he evidently met with disappointment.

That he continued to wander on was evidence of a determination to find some sort of game. Josh was not much of a hunter, and he did hate to be unmercifully guyed by Jimmy and Nick, whenever he came back empty handed.

“It can’t be long now, before we make some sort of discovery,” George finally remarked.

“I agree with you,” Jack said, over his shoulder.

“How far are we from camp now, Jack?” continued the skipper of the Wireless.

“Perhaps a mile, more or less,” answered the pilot of the expedition.

“But not so far as to be beyond the sound of the yell we put up, eh?” continued George.

“Unless Josh suddenly became stone deaf, he must have heard us,” replied the other.
