He ceased abruptly and suddenly turned pale.
The reason was not far to seek. A huge spear had whizzed past his head, missing it by only a very few inches!
For some time neither of the youths spoke. They stared fearfully into the green depths of the forest whence the spear had been thrown.
Then, seeing no signs of natives, Bob broke the silence.
“What do you think?” he asked in a low voice, never taking his eyes from the jungle.
Joe waited a moment before replying. He had not yet recovered from the horror that had seized him.
“I—I don’t know what to think,” he said tensely. “Savages, cannibals, maybe.”
“But why don’t they attack us?” asked Bob, greatly puzzled.
“More than I know.”
The youths remained where they were for several minutes, fearful to move on for fear of being struck from behind. But when after quite a while nothing more happened they concluded it was safe to go on.
