For a long second Lennox gazed at him in open-mouthed astonishment. "My stars, boy!" he cried at last. "Was I mistaken in thinking you were a born tenderfoot--after all? Can it be that a little of your old grandfather's skill has been passed down to you? But you can't do it again." But Dan did do it again. If anything, the bullet was a little nearer the center. And then he aimed at a more distant tree. But the hammer snapped down ineffectively on the breech. He turned with a look of question. "Your gun only holds five shots," Lennox explained. Reloading, Dan tried a more difficult target--a trunk almost one hundred yards distant. Of course it would have been only child's play to an experienced hunter; but to a tenderfoot it was the difficult mark indeed. Twice out of four shots Dan hit the tree trunk, and one of his two hits was practically a bull's-eye. His two misses were the result of the same mistake he had made before,--attempting to hold his aim too long. The shots rang far through the quiet woods, long-drawn from the echoes that came rocking back from the hills. In contrast with the deep silence that is really an eternal part of the mountains, the sound seemed preternaturally loud. All over the great sweep of canyon, the wild creatures heard and were startled. One could easily imagine the Columbian deer, gone to their buckbrush to sleep, springing up and lifting pointed ears. There is no more graceful action in the whole animal world than this first, startled spring of a frightened buck. Then old Woof, feeding in the berry bushes, heard the sound too. Woof has considerably more understanding than most of the wild inhabitants of the forest, and maybe that is why he left his banquet and started falling all over his awkward self in descending the hill. It might be that Lennox would want to procure his guest a sample of bear steak; and Woof didn't care to be around to suggest such a thing. At least, that would be his train of thought according to those naturalists who insist on ascribing human intelligence to all the forest creatures. But it is true that Woof had learned to recognize a rifle shot, and he feared it worse than anything on earth. Far away on the ridge top, a pair of wolves sat together with no more evidence of life than two shadows. One of the most effective accomplishments a wolf possesses is its ability to freeze into a motionless thing, so the sharpest eye can scarcely detect him in the thickets. It is an advantage in hunting, and it is an even greater advantage when being hunted. Yet at the same second they sprang up, simply seemed to spin in the dead pine needles, and brought up with sharp noses pointed and ears erect, facing the valley.
