It was the fact that Neewa made no sound, that no cry came from him, that brought Miki to his feet with his lips drawn back and a snarl in his throat. All at once fear went out of him and in its place came a wild and almost joyous exultation. He recognized their enemy—A BIRD. To him birds were a prey, and not a menace. A dozen times in their journey down from the Upper Country Challoner had shot big Canada geese and huge-winged cranes. Miki had eaten their flesh. Twice he had pursued wounded cranes, yapping at the top of his voice, AND THEY HAD RUN FROM HIM. He did not bark or yelp now. Like a flash he launched himself into the feathered mass of the owl. His fourteen pounds of flesh and bone landed with the force of a stone, and Oohoomisew was torn from his hold and flung with a great flutter of wings upon his side.

Before he could recover his balance Miki was at him again, striking full at his head, where he had struck at the wounded crane. Oohoomisew went flat on his back—and for the first time Miki let out of his throat a series of savage and snarling yelps. It was a new sound to Oohoomisew and his blood-thirsty brethren watching the struggle from out of the gloom. The snapping beaks drifted farther away, and Oohoomisew, with a sudden sweep of wings, vaulted into the air.

With his big forefeet planted firmly and his snarling face turned up to the black wall of the tree-tops Miki continued to bark and howl defiantly. He wanted the bird to come back. He wanted to tear and rip at its feathers, and as he sent out his frantic challenge Neewa rolled over, got on his feet, and with a warning squeal to Miki once more set off in flight. If Miki was ignorant in the matter, HE at least understood the situation. Again it was the instinct born of countless generations. He knew that in the black pits about them hovered death—and he ran as he had never run before in his life. As Miki followed, the shadows were beginning to float nearer again.

Ahead of them they saw a glimmer of sunshine. The trees grew taller, and soon the day began breaking through so that there were no longer the cavernous hollows of gloom about them. If they had gone on another hundred yards they would have come to the edge of the big plain, the hunting grounds of the owls. But the flame of self-preservation was hot in Neewa's head; he was still dazed by the thunderous beat of wings; his sides burned where Oohoomisew's talons had scarred his flesh; so, when he saw in his path a tangled windfall of tree trunks he dived into the security of it so swiftly that for a moment or two Miki wondered where he had gone.

Crawling into the windfall after him Miki turned and poked out his head. He was not satisfied. His lips were still drawn back, and he continued to growl. He had beaten his enemy. He had knocked it over fairly, and had filled his jaws with its feathers. In the face of that triumph he sensed the fact that he had run away in following Neewa, and he was possessed with the desire to go back and have it out to a finish. It was the blood of the Airedale and the Spitz growing stronger in him, fearless of defeat; the blood of his father, the giant hunting-hound Hela. It was the demand of his breed, with its mixture of wolfish courage and fox-like persistency backed by the powerful jaws and Herculean strength of the Mackenzie hound, and if Neewa had not drawn deeper under the windfall he would have gone out again and yelped his challenge to the feathered things from which they had fled.

Neewa was smarting under the red-hot stab of Oohoomisew's talons, and he wanted no more of the fight that came out of the air. He began licking his wounds, and after a while Miki went back to him and smelled of the fresh, warm blood. It made him growl. He knew that it was Neewa's blood, and his eyes glowed like twin balls of fire as they watched the opening through which they had entered into the dark tangle of fallen trees.

For an hour he did not move, and in that hour, as in the hour after the killing of the rabbit, he GREW. When at last he crept out cautiously from under the windfall the sun was sinking behind the western forests. He peered about him, watching for movement and listening for sound. The sagging and apologetic posture of puppyhood was gone from him. His overgrown feet stood squarely on the ground; his angular legs were as hard as if carven out of knotty wood; his body was tense, his ears stood up, his head was rigidly set between the bony shoulders that already gave evidence of gigantic strength to come. About him he knew was the Big Adventure. The world was no longer a world of play and of snuggling under the hands of a master. Something vastly more thrilling had come into it now.

After a time he dropped on his belly close to the opening under the windfall and began chewing at the end of rope which dragged from about his neck. The sun sank lower. It disappeared. Still he waited for Neewa to come out and lie with him in the open. As the twilight thickened into deeper gloom he drew himself into the edge of the door under the windfall and found Neewa there. Together they peered forth into the mysterious night.

For a time there was the utter stillness of the first hour of darkness in the northland. Up in the clear sky the stars came out in twos and then in glowing constellations. There was an early moon. It was already over the edge of the forests, flooding the world with a golden glow, and in that glow the night was filled with grotesque black shadows that had neither movement nor sound. Then the silence was broken. From out of the owl-infested pits came a strange and hollow sound. Miki had heard the shrill screeching and the TU-WHO-O-O, TU-WHO-O-O, TU-WHO-O-O of the little owls, the trap-pirates, but never this voice of the strong-winged Jezebels and Frankensteins of the deeper forests—the real butchers of the night. It was a hollow, throaty sound—more a moan than a cry; a moan so short and low that it seemed born of caution, or of fear that it would frighten possible prey. For a few minutes pit after pit gave forth each its signal of life, and then there was a silence of voice, broken at intervals by the faint, crashing sweep of great wings in the spruce and balsam tops as the hunters launched themselves up and over them in the direction of the plain.

The going forth of the owls was only the beginning of the night carnival for Neewa and Miki. For a long time they lay side by side, sleepless, and listening. Past the windfall went the padded feet of a fisher-cat, and they caught the scent of it; to them came the far cry of a loon, the yapping of a restless fox, and the MOOING of a cow moose feeding in the edge of a lake on the farther side of the plain. And then, at last, came the thing that made their blood run faster and sent a deeper thrill into their hearts.
