At last Blackstock called the party in, and around the solitary footprint they all sat down and smoked. One after another they made suggestions, but each suggestion had its futility revealed and sealed by a stony stare from Blackstock, and was no more befriended by its author.

At last Blackstock rose to his feet, and gave a hitch to his belt.

"I don't mind tellin' ye, boys," said he, "it beats me fair. But one thing's plain enough, Black Dan ain't here, an' he ain't likely to come here lookin' for us. Spread out now, an' we'll work on ahead, an' see ef we can't pick up somethin'. You, Big Andy, you keep right along behind me. There's an explanation to everything—an' we'll find this out afore along, or my name's Dinnis."

Over the next three or four hundred yards, however, nothing of significance was discovered by any of the party. Then, breaking through a dense screen of branches, Blackstock came upon the face of a rocky knoll, so steep, at that point, that hands and feet together would be needed to climb it. Casting his eyes upwards, he saw what looked like the entrance to a little cave.

A whistle brought the rest of the party to his side. A cave always holds possibilities, if nothing else. Blackstock spread his men out again, at intervals of three or four paces, and all went cautiously up the steep, converging on the entrance. Blackstock, in the centre, shielding himself behind a knob of rock, peered in.

The place was empty. It was hardly a cave, indeed, being little more than a shallow recess beneath an overhanging ledge. But it was well sheltered by a great branch which stretched upwards across the opening. Blackstock sniffed critically.

"A bear's den," he announced, stepping in and scrutinizing the floor.

The floor was naked rock, scantily littered with dead leaves and twigs. These, Blackstock concluded, had been recently disturbed, but he could find no clue to what had disturbed them. From the further side, however—to Blackstock's right—a palpable trail, worn clear of moss and herbage, led off by a narrow ledge across the face of the knoll. Half a dozen paces further on the rock ended in a stretch of stiff soil. Here the trail declared itself. It was unmistakably that of a bear, and unmistakably, also, a fresh trail.

Waving the rest to stop where they were, Blackstock followed the clear trail down from the knoll, and for a couple of hundred yards along the level, going very slowly, and searching it hawk-eyed for some sign other than that of bear. At length he returned, looking slightly crestfallen.

"Nawthin' at all but bear," he announced in an injured voice. "But that bear seems to have been in a bit of a hurry, as if he was gittin' out o' somebody's way—Black Dan's way, it's dollars to doughnuts. But where was Black Dan, that's what I want to know?"
