Tom was moving about now, and appeared to be scanning the rock at his feet eagerly. Undoubtedly he was looking for the well worn trail which, he had told his chum, he expected to discover, leading upward toward that dark spot in the rocky wall, where, according to his figuring, the animal's den had its yawning mouth, although as yet they had not actually looked into it.

So Felix stood there, waiting, and holding his gun in his hands, wondering what he might be expected to do should the grizzly appear unexpectedly from some other quarter, heading toward his den.

And possibly because Tom had impressed the necessity of a tree so strongly on his mind Felix even made sure that there was one of these growing close at hand which he believed might be scaled in a hurry if there arose any need.

He saw that his companion was now examining the ground more closely than ever; and there was that about his manner to tell that he must have made a discovery of some sort.

A few seconds later the Western lad arose to his feet, and his face shone with satisfaction as he turned toward his friend.

"It's here, just as I said, Felix," he whispered; "and from the signs I'm pretty sure the old fellow is right now squatted in his den. Things look all right to me, and the next thing is to coax him out. Like you, I only hope he's hungry; but no matter whether he is or not, he's just got to come, and that's all there is to it."

Like a general arranging his plan of campaign, so Tom looked around him, up at the place where the den of the monster was believed to be, and then in search of the available tree.

"That's where we ought to perch," he remarked, pointing to a spot close by. "We can each have a tree, which is really better than both getting up in the same one; for while he's trying to get at me, you can pump him full of lead. I'm only going to dip in here in a case of necessity, because I want you to say you got him all by yourself."

"Up a tree," muttered Felix, disconsolately; but his chum paid no attention to the half protest, being satisfied that time would vindicate his course.
