Whopper arose, and waiting to make certain that his companion was wide awake, Shep threw himself on the couch, which had been formed of some leaves found at the rear of the hollow. He soon fell into a troubled sleep, which lasted about three hours, when he awoke at the sound of Whopper's voice calling him.
"Is it time to get up?" he questioned, sleepily.
"Shep, I hear wolves!"
"Wolves!" and now the doctor's son leaped to his feet and glanced toward his shotgun, which rested against the rocky wall. "Are you certain?"
"Listen!"
Both boys bent their ears and for a full minute neither made a sound.
Then Shep shook his head.
"I can't hear anything now," he said.
"Well, I heard them before," answered Whopper, positively. "Must have been a million of 'em, too!"
"Whopper, you've got a million wolves on the brain."
"Have I? Well, I know—Listen!"
