Blackstock followed his gaze. The tree was an ancient rock maple, its branches large but comparatively few in number. Blackstock could see clear to its top. It was obvious that the tree could afford no hiding-place to anything larger than a wild-cat. Nevertheless, as Blackstock studied it, a gleam of sudden insight passed over his face.

"Jim 'pears to think Black Dan's gone to Heaven," remarked Saunders drily.

"Ye can't always tell what Jim's thinkin'," retorted Blackstock. "But I'll bet it's a clever idea he's got in his black head, whatever it is."

He scanned the tree anew and the other trees nearest whose branches interlaced with it. Then, with a sharp "Come on, Jim," he started towards the knoll, eyeing the branches overhead as he went. The rest of the party followed at a discreet distance.

Crippled as he was, Jim could not climb the steep face of the knoll, but his master helped him up. The instant he entered the cave he growled savagely, and once more the stiff hair rose along his back. Blackstock watched in silence for a moment. He had never before noticed, on Jim's part, any special hostility toward bears, whom he was quite accustomed to trailing. He glanced up at the big branch that overhung the entrance, and conviction settled on his face. Then he whispered, sharply, "Seek him, Jim." And Jim set off at once, as fast as he could limp, along the trail of the bear.

"Come on, boys," called Blackstock to his posse. "Ef we can't find Black Dan we may as well hev a little bear-hunt to fill in the time. Jim appears to hev a partic'lar grudge agin that bear."

The men closed up eagerly, expecting to find that Blackstock, with Jim's help, had at last discovered some real signs of Black Dan. When they saw that there was still nothing more than that old bear's trail, which they had already examined, Long Jackson began to grumble.

"We kin hunt bear any day," he growled.

"I guess Tug ain't no keener after bear this day than you be," commented MacDonald. "He's got somethin' up his sleeve, you see!"

"Mebbe it's a tame b'ar, a trained b'ar, an' Black Dan's a-ridin' him horseback," suggested Big Andy.
