“That’s easy,” answered Tad. “When you’re not making a noise we know you’re somewhere else. Let’s see what the ice did to our camp.”

“Heap one piece ice fall,” grunted the guide. “Him sit on fire. Innua him mad, by jink!”

“Is Innua the scoundrel who has been throwing sections of mountains at us?” demanded Walter.

“He means the mountain spirit,” explained Tad. “Don’t you recall that Anvik wouldn’t start out with us the first day because he said 175the mountain spirit was in a blue funk, or something of the sort?”

“Oh, yes.”

“Old Innua must have been in a rage to-night then, and we are lucky that we weren’t in range of his projectiles,” chuckled Tad.

Beyond destroying their fire, no damage had been done to the camp. However, after the excitement no one felt like sleep, so the boys sat about the fire discussing the ice avalanche for an hour or more. Then, at the Professor’s urgent insistence, they turned in. Anvik long since had wound himself up in his blanket and gone to sleep.

Just as the dawn was graying, Tad got up, and shouldering his rifle slipped from the camp unobserved by anyone except the Indian. Anvik opened one eye, regarded the boy inquiringly, then closing the eye, dozed off. He was by this time too well used to Tad’s morning excursions to ask any questions. He knew the boy was well able to take care of himself.

Tad had a two-fold purpose in view in going out this morning. He wanted to get some fresh meat for the outfit and he also was curious to know what the smoke of the previous evening had meant. While he did not expect to come up with any strangers, he thought that, perhaps he might discover something.

176Tad did. He had proceeded less than a mile from camp when he smelled smoke. At first he thought the odor must come from his own camp, then he saw that the slight breeze was from the opposite direction.
