As soon as she had gnawed through the thong, and nosed at Shasta to satisfy herself that he was not only free but able to make use of his legs, Nitka gave the sign to Shoomoo. What sign it was, no one not born of wolf blood could have told you. Even Shasta could not have done so, though he was aware that the sign was given, for the unspoken sign-language of the animals is not to be cramped into the narrow shapes of human speech. Whatever the sign was, Shoomoo obeyed. He slid round the nearest tepee as noiselessly as if his great body floated on the air. Shasta followed, with Nitka close behind. She had led the way into the camp, because of her greater cunning, but now it was for Shoomoo to find the way out. Her place now was close to her strange cub, so that she could protect him on the instant from any danger that might threaten.
Two grey shadows had drifted into camp. Now three were stealing out, under the stars, and no human eye watched their stealthy departure. All would have been well, if an unlucky husky dog had not happened to wake as the three shadows glided past.
There was a short bark, a rush, and a worrying snarl. Then one piercing yelp rent the silence, and the husky lay a bleeding form, thrown by Shoomoo's jaws three yards away. With that the whole husky pack was on its feet, roused from its slumbers in an instant. At least twenty furious dogs hurled themselves at the wolves. Never had Nitka and Shoomoo a finer chance to show their fighting power. From two large grey timber-wolves they seemed to transform themselves into leaping whirlwinds that snatched and tore, and flung husky dogs like chaff into the air. At first Shasta was in the centre of the fight. He could not, of course, help his foster parents, for his teeth and hands were useless at such a time; all he could do was to save himself as much as possible from the brunt of the attack. This he did by crouching, leaping and running when the right moment came. Beyond everything else, he kept his throat protected with his arms, for his wolf-knowledge and training taught him that this was the danger spot, which if you did not guard, meant the losing of your life.
Once or twice he felt a stinging pain, as a husky snatched at him and the sharp teeth scored his flesh; but each time the dog paid dearly for his rashness, and was not for biting any more. It was only when Nitka or Shoomoo was busy finishing a dog that the thing happened. Otherwise, they kept close to Shasta, one on each side, guarding him from attack. Each time Shasta was touched, Nitka's anger passed all bounds. She not only punished the offender with death, but she tore at the other dogs with redoubled fury.
So the fight rolled towards the forest—a yapping, snarling mass of leaping bodies and snatching teeth. In its track the bodies of dead and dying huskies lay bleeding on the dark ground.
The thing that Shasta dreaded most was lest the Indians should come to the rescue of their dogs. But having had one false alarm, they did not trouble to rouse themselves again, and even Looking-All-Ways remained on his bed of buffalo robes and said evil things of the huskies for disturbing his repose.
It was not many minutes before the fight was over. The huskies, finding themselves outmatched by the superior strength and fury of the wolves, began to lose heart. When the moment came that they had had enough of it, the wolves seemed to know it by instinct They passed in a flash, from defence to attack, and, covering Shasta's retreat towards the trees, they charged the pack with unequalled fury. Such an onset was irresistible. The huskies gave way before it, completely routed. Their only care was how to save their skins, as they fled, yelping into the night. Of the twenty dogs which had attacked the wolves, only ten found their way back to camp; and of these many had ugly wounds which they carried as scars to the end of their days. It had been so great a fight that the Indians marvelled when the morning light showed them the blood-stained ground and the bodies of the dogs that had died in the fray.
All the way back through the dark woods Shasta felt a great joy within him. And the gloom seemed alive with things that gave him greeting as he ran. He could not see them clearly—those things. Yet now and then something shadowy stirred, and swayed towards him, or drifted softly by. And though they were so faint and shadowy, he knew them for the good, secret things of the forest, which none but the wild creatures know. His wounds were a little sore, but, even as he ran, Nitka found time to doctor them with her tongue. She paid no heed to her own. There would be time enough to attend to them when they had reached the den. Neither she nor Shoomoo had really dangerous wounds, although they were bleeding in many places. A day or two's rest and licking would make them all right, and as long as their man-cub was safe they did not care.
It was bright morning before they reached the den. The sun had risen and was pouring down upon the Bargloosh all the freshness of his early beams. From the tip of a fir branch, a clear little song slipped into the morning air. It was Killooleet, the white-throated sparrow, trilling his morning tune. He had his nest somewhere near the den, only the wolves never found out where. All they knew him by was his song, and the flicker of his flight as he darted daintily past. The very fanning of his wings seemed to sweeten the air. As for his song—he spilt it out at them in little trickling tunes all through the day, or whenever he happened to wake up in the night. The old wolves didn't mind him much, one way or the other, but Shasta was fond of him, and used to make a gurgle in his throat whenever Killooleet spilt his voice. And now, as he approached the cave, the song of Killooleet seemed a welcome home, and when he looked up into the tree there was Killooleet perched on the fir-tip, with the sunlight shining full on his little wobbling throat!
