Dan's reply was to lift the rifle lightly to his shoulder, glance quickly along the trigger, and fire. The bullet struck within one inch of the center of the pine.

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.

A human being likely would have wondered at their action. It is doubtful that human ears could have detected that faint tremor in the air which was all that was left of the rifle report. But of course this is a question that would be extremely difficult to prove; for as a rule the senses of the larger forest creatures, with the great exception of scent, are not as perfectly developed as those of a human being. A wolf can see better than a man in the darkness, but not nearly as far in the daylight. But the wolves knew this sound. Too many times they had seen their pack-fellows die in the snow when such a report as this, only intensified a thousand times, cracked at them through the winter air. No animal in all the forest has been as relentlessly hunted as the wolves, and they have learned their lessons. For longer years than most men would care to attempt to count, men have waged a ceaseless war upon them. And they have learned that their safety lies in flight.

Very quietly, and quite without panic, the wolves turned and headed farther into the forests. Possibly no other animal would have been frightened at such a distance. And it is certainly true that in the deep, winter snows not even the wolves would have heeded the sound. The snows bring Famine; and when Famine comes to keep its sentry-duty over the land, all the other forest laws are immediately forgotten or ignored. The pack forgets all its knowledge of the deadliness of men in the starving times.

The grouse heard the sound, and, silly creatures that they are, even they raised their heads for a single instant from their food. The felines—the great, tawny mountain lions and their smaller cousins, the lynx—all devoted at least an instant of concentrated attention to it. A raccoon, sleeping in a pine, opened its eyes, and a lone bull elk, such as some people think is beyond all other things the monarch of the forest, rubbed his neck against a tree trunk and wondered.
