Desmond and Billy felt very anxious while Tom was away, lest he should fall into the hands of the Papuans.

“If they get him they will cut off his head,” said Billy, “and we shall never see him again.”

“Tom knows what he is about; and unless the enemy suspect that we are in their rear, and are looking about, there is not much risk of his being discovered,” answered Desmond.

“It would have been better to have sent one of the black fellows,” observed Billy. “I say, Desmond, what are we to do for grub? I’m getting very sharp set, in spite of my feelings.”

“I suspect we shall get nothing to-night,” answered Desmond. “If we were to fire we should betray ourselves, and have the enemy down upon us. Perhaps Tom will report that they have moved away, and we shall after all be able to reach the beach. Lieutenant Norman is sure not to go away without us.”

“But he won’t stop if he fancies that we are killed; and that will be his opinion, depend upon it,” said Billy, in a melancholy tone.

“Hark! I hear some one coming,” said Desmond. “Keep quiet!” It proved to be Tom, who looked unusually grave.

“I have been a considerable distance,” he said, “and have had a sharp run for it to keep ahead of the enemy. They are coming this way, and I question whether this will prove a secure hiding-place; for, as I watched them, they seemed to be stowing themselves away between trees or behind hillocks and rocks, and some of them are sure to pop in here.”

Nick and Pipes appeared quickly to understand what he was saying. “Den we go on higher,” said Nick, pointing towards the bank of the river.

It at once occurred to Tom that the Papuan expected to find a canoe by which they might escape down the river and get out to sea. He accordingly without hesitation followed Nick’s advice; and the party set out, following the two Papuans as fast as they could run, hoping to avoid being seen by the enemy. Instead, however, of keeping down the stream, as Tom expected they would do, they proceeded up it.
