"It's a man," he whispered. "And there's another and another," he added a moment later.

The dogs were now growling almost continually.

"What'll we do?" Jack whispered.

"We wait, see what um do," Lucky whispered back.

"How many have you seen?"

"Six so far," Bob whispered, and a moment later added: "They're working around where the dogs are."

"That no go," Lucky growled. "Mebby um keel dog."

As he spoke the Indian leaped to the edge of the snow and shouted:

"Who you, eh?"

For a moment there was silence broken only by the snarls of the dogs, then, from behind a tree, only about ten feet from where he stood, stepped a man. The boys could see that it was a man of large frame standing well over six feet, but it was not light enough to guess at his nationality until he spoke.
