The two boys left behind rested for the best part of half an hour. Then, thinking it was time for Phil to rejoin them, they called their chum's name.
No answer came back, and, walking up the stream a short distance, Dave repeated the call. Still there was no reply.
"That's queer," he told Roger. "I wonder why he doesn't reply?"
"I am sure I don't know," said the senator's son. "Let us look for him." And both started after Phil, wondering what could be wrong.
