The Indian seemed pleased at the idea, and soon led the way toward the range of hills whither the foot-prints pointed.

"The first thing we know," Thede suggested, "we'll be running into a nest of black bears. They're thick as bees up in this country, and they'll be hungry, too, with all this snow on the ground."

The words were hardly out of his mouth before a succession of low, angry growls came to the ears of the boys, and the next moment they saw Oje springing into the lower branches of a great fir tree.

"I guess he knows what's good for his health!" shouted Sandy. "Me for a tree, too!"

The boys probably never made quicker motions in their lives.

"Have you got a searchlight with you?" asked Thede.

Sandy shook his head sadly.

"Then we can't see to shoot the beasts," wailed Thede, "and it looks to me like one of those long, cold nights in a tree!"
