"I am afraid that means trouble of some kind," said Lieutenant Carey, anxiously, after he had fired two answering shots.

Hurrying down the pathway, which they found led to the water on the opposite side of the island from that on which they had landed, they plunged into the forest, and were surprised to notice how dark it had already grown. Its intricacies were so bewildering and its difficulties so numerous that it was nearly an hour after they heard the shots before they came within sound of a voice answering their repeated calls.

At length they reached the place where they had left the boats, and here they found Worth alone, and so panic-stricken that it was with difficulty he could answer their eager questions.

"Why had he fired those shots?"

"Where was Quorum?"

"Where were the boats?"

"I fired them to call you back," answered the boy, "and I don't know where Quorum is nor where the boats are. They were here when I left, and when I came back they were gone. This was all I found here." With this Worth pointed to a bag of hardtack that lay on the ground at his feet. "And I'm afraid poor Quorum has been killed, for I know he never would have left us. I thought perhaps you were killed too, and that I was left here all alone, and I've been getting more and more frightened, until I think I should have gone crazy if you had not come when you did."

"You poor boy!" said the Lieutenant, soothingly, "I don't wonder that you were frightened. I should have been myself. But how did you happen to leave Quorum? and what was he doing when you left him?"

"He was sitting in the cruiser, and I only left him for a minute, because I heard such a big turkey gobbler right here in the woods close to us. I thought it would be such a pleasant surprise for you to have me get him for supper, and I was sure there weren't any panthers or rattlesnakes here. So I just crept into the bushes to get a shot at him, and he kept going farther and farther off, and I kept following him. I didn't see him at all, and after a while I didn't hear him any more either, so I thought I'd better come back. When I got here, I couldn't find Quorum or the boats, so I fired my gun as a signal."

"And you haven't seen nor heard anything of Quorum since?" inquired Lieutenant Carey, looking puzzled and anxious.
