"What's the matter?" he cried as he hurried forward.
"Afraid I've sprained or broken my ankle," he groaned.
"Maybe it's not so bad as you think," Bob encouraged as he put his hands beneath his shoulders and helped him to get to his feet.
But Jack sank down again with a low moan of pain.
"I can't do it," he groaned.
"Let me have a look at it."
Bob unfastened the thongs which held the foot to the snow-shoe and carefully unlaced the moccasin.
"Am I hurting?" he asked.
"Some, but it doesn't matter."
By the time he had drawn off the heavy sock the ankle had swollen somewhat and, as carefully as possible, he examined it. First aid to the injured had been taught them at the military college and both boys knew not a little about such injuries.
