"Thunder! what a Bear!" The nose-mark was a head and neck above Baldy's highest reach. Now, a simple Bear would have gone quietly away after this discovery; but Baldy felt that the mountains owed him a living, and here was a good one if he could keep out of the way of the big fellow. He nosed about the place, kept a sharp lookout for the present owner, and went on feeding wherever he ran across a good thing. [Illustration] A step or two from this ominous tree was an old pine stump. In the Bitter-roots there are often mice-nests under such stumps, and Baldy jerked it over to see. There was nothing. The stump rolled over against the sign-post. Baldy had not yet made up his mind about it; but a new notion came into his cunning brain. He turned his head on this side, then on that. He looked at the stump, then at the sign, with his little pig-like eyes. Then he deliberately stood up on the pine root, with his back to the tree, and put his mark away up, a head at least above that of Wahb. He rubbed his back long and hard, and he sought some mud to smear his head and shoulders, then came back and made the mark so big, so strong, and so high, and emphasized it with such claw-gashes in the bark, that it could be read only in one way--a challenge to the present claimant from some monstrous invader, who was ready, nay anxious, to fight to a finish for this desirable range. [Illustration: "HE DELIBERATELY STOOD UP ON THE PINE ROOT."] Maybe it was accident and maybe design, but when the Roachback jumped from the root it rolled to one side. Baldy went on down the canyon, keeping the keenest lookout for his enemy. It was not long before Wahb found the trail of the interloper, and all the ferocity of his outside-the-Park nature was aroused. He followed the trail for miles on more than one occasion. But the small Bear was quick-footed as well as quick-witted, and never showed himself. He made a point, however, of calling at each sign-post, and if there was any means of cheating, so that his mark might be put higher, he did it with a vim, and left a big, showy record. But if there was no chance for any but a fair register, he would not go near the tree, but looked for a fresh tree near by with some log or side-ledge to reach from. [Illustration]
