Half an hour later he looked down from the top of the slope through his glasses. He saw Muskwa, a black dot. The cub had stopped, and was waiting confidently for him to return.

And trying to laugh again, but failing dismally, Langdon rode over the divide and out of Muskwa's life.

[CHAPTER TWENTY]

For a good half-mile Muskwa followed over the trail of Langdon. He ran at first; then he walked; finally he stopped entirely and sat down like a dog, facing the distant slope. Had Langdon been afoot he would not have halted until he was tired. But the cub had not liked his pannier prison. He had been tremendously jostled and bounced about, and twice the horse that carried him had shaken himself, and those shakings had been like earthquakes to Muskwa. He knew that the cage as well as Langdon was ahead of him. He sat for a time and whimpered wistfully, but he went no farther. He was sure that the friend he had grown to love would return after a little. He always came back. He had never failed him. So he began to hunt about for a spring beauty or a dog-tooth violet, and for some time he was careful not to stray very far away from where the outfit had passed.

All that day the cub remained in the flower-strewn meadows under the slope; it was very pleasant in the sunshine, and he found more than one patch of the bulbous roots he liked. He dug, and he filled himself, and he took a nap in the afternoon; but when the sun began to go down and the heavy shadows of the mountain darkened the valley he began to grow afraid.

He was still a very small baby of a cub, and only that one dreadful night after his mother had died had he spent entirely alone. Thor had replaced mother, and Langdon had taken the place of Thor, so that until now he had never felt the loneliness and emptiness of darkness. He crawled under a clump of thorn close to the trail, and continued to wait, and listen, and sniff expectantly. The stars came out clear and brilliant, but to-night their lure was not strong enough to call him forth. Not until dawn did he steal out cautiously from his shelter of thorn.

The sun gave him courage and confidence again and he began wandering back through the valley, the scent of the horse-trail growing fainter and fainter until at last it disappeared entirely. That day Muskwa ate some grass and a few dog-tooth violet roots, and when the second night came he was abreast of the slope over which the outfit had come from the valley in which were Thor and Iskwao. He was tired and hungry, and he was utterly lost.

That night he slept in the end of a hollow log. The next day he went on, and for many days and many nights after that he was alone in the big valley. He passed close to the pool where Thor and he had met the old bear, and he nosed hungrily among the fishbones; he skirted the edge of the dark, deep lake; he saw the shadowy things fluttering in the gloom of the forest again; he passed over the beaver dam, and he slept for two nights close to the log-jam from which he had watched Thor throw out their first fish. He was almost forgetting Langdon now, and was thinking more and more about Thor and his mother. He wanted them. He wanted them more than he had ever wanted the companionship of man, for Muskwa was fast becoming a creature of the wild again.

It was the beginning of August before the cub came to the break in the valley and climbed up the slope where Thor had first heard the thunder and had first felt the sting of the white men's guns. In these two weeks Muskwa had grown rapidly, in spite of the fact that he often went to bed on an empty stomach; and he was no longer afraid of the dark. Through the deep, sunless canyon above the clay wallow he went, and as there was only one way out he came at last to the summit of the break over which Thor had gone, and over which Langdon and Bruce had followed in close pursuit. And the other valley—his home—lay under Muskwa.

Of course he did not recognize it. He saw and smelled in it nothing that was familiar. But it was such a beautiful valley, and so abundantly filled with plenty and sunshine, that he did not hurry through it. He found whole gardens of spring beauties and dog-tooth violets. And on the third day he made his first real kill. He almost stumbled over a baby whistler no larger than a red squirrel, and before the little creature could escape he was upon it. It made him a splendid feast.
