He sees a tree that suits his fancy and immediately stands on his hind legs beside it. Then he scratches the bark, just as high up as he can reach. The idea seemed to be that if any other bear should journey along that way, should find that he couldn't reach as high, he would immediately quit the territory. But it doesn't work out in practice. Nine times out of ten there will be a dozen Woofs in the same neighborhood, no two of equal size, yet they hunt their berries and rob their bee trees in perfect peace. Perhaps the impulse still remains, a dim, remembered instinct, long after it has outlived its usefulness,--just as man, ten thousand years after his arboreal existence, will often throw his arms into the air as if to seize a tree branch when he is badly frightened. It was a roundabout trail home, but yet it had its advantages. It took him within two miles of Snowbird's lookout station, and at this hour of day he had been particularly fortunate in finding her at a certain spring on the mountain side. It was a rather singular coincidence. Along about four he would usually find himself wandering up that way. Strangely enough, at the same time, it was true that she had an irresistible impulse to go down and sit in the green ferns beside the same spring. They always seemed to be surprised to see one another. In reality, either of them would have been considerably more surprised had the other failed to put in an appearance. And always they had long talks, as the afternoon drew to twilight. "But I don't think you ought to wait so late before starting home," the girl would always say. "You're not a human hawk, and it is easier to get lost than you think." And this solicitude, Dan rightly figured, was a good sign. There was only one objection to it. It resulted in an unmistakable inference that she considered him unable to take care of himself,--and that was the last thing on earth that he wanted her to think. He understood her well enough to know that her standards were the standards of the mountains, valuing strength and self-reliance above all things. He didn't stop to question why, every day, he trod so many weary miles to be with her.
