As this particular "porky" advanced upon Muskwa and Thor, he was communing happily with himself, the chuckling notes he made sounding very much like a baby's cooing. He was enormously fat, and as he waddled slowly along his side and tail quills clicked on the stones. His eyes were on the path at his feet. He was deeply absorbed in nothing at all, and he was within five feet of Thor before he saw the grizzly. Then, in a wink, he humped himself into a ball. For a few seconds he scolded vociferously. After that he was as silent as a sphinx, his little red eyes watching the big bear.
Thor did not want to kill him, but the path was narrow, and he was ready to go on. He advanced a foot or two, and Porky turned his back toward Thor and made ready to deliver a swipe with his powerful tail. In that tail were several hundred quills. As Thor had more than once come into contact with porcupine quills, he hesitated.
Muskwa was looking on curiously. He still had his lesson to learn, for the quill he had once picked up in his foot had been a loose quill. But since the porcupine seemed to puzzle Thor, the cub turned and made ready to go back along the slide if it became necessary. Thor advanced another foot, and with a sudden chuck, chuck, chuck—the most vicious sound he was capable of making—Porky advanced backward and his broad, thick tail whipped through the air with a force that would have driven quills a quarter of an inch into the butt of a tree. Having missed, he humped himself again, and Thor stepped out on the boulder and circled around him. There he waited for Muskwa.
Porky was immensely satisfied with his triumph. He unlimbered himself; his quills settled a bit; and he advanced toward Muskwa, at the same time resuming his good-natured chuckling. Instinctively the cub hugged the edge of the path, and in doing so slipped over the edge. By the time he had scrambled up again Porky was four or five feet beyond him and totally absorbed in his travel.
The adventure of the sheep-trail was not yet quite over, for scarcely had Porky maneuvered himself to safety when around the edge of the big boulder above appeared a badger, hot on the fresh and luscious scent of his favourite dinner, a porcupine. This worthless outlaw of the mountains was three times as large as Muskwa, and every ounce of him was fighting muscle and bone and claw and sharp teeth. He had a white mark on his nose and forehead; his legs were short and thick; his tail was bushy, and the claws on his front feet were almost as long as a bear's. Thor greeted him with an immediate growl of warning, and the badger scooted back up the trail in fear of his life.
Meanwhile Porky lumbered slowly along in quest of new feeding-grounds, talking and singing to himself, forgetting entirely what had happened a minute or two before, and unconscious of the fact that Thor had saved him from a death as certain as though he had fallen over a thousand-foot precipice.
For nearly a mile Thor and Muskwa followed the Bighorn Highway before its winding course brought them at last to the very top of the range. They were fully three-quarters of a mile above the creek-bottom, and so narrow in places was the crest of the mountain along which the sheep-trail led that they could look down into both valleys.
To Muskwa it was all a greenish golden haze below him; the depths seemed illimitable; the forest along the stream was only a black streak, and the parklike clumps of balsams and cedars on the farther slopes looked like very small bosks of thorn or buffalo willow.
Up here the wind was blowing, too. It whipped him with a strange fierceness, and half a dozen times he felt the mysterious and very unpleasant chill of snow under his feet. Twice a great bird swooped near him. It was the biggest bird he had ever seen—an eagle. The second time it came so near that he heard the beat of it, and saw its great, fierce head and lowering talons.
Thor whirled toward the eagle and growled. If Muskwa had been alone, the cub would have gone sailing off in those murderous talons. As it was, the third time the eagle circled it was down the slope from them. It was after other game. The scent of the game came to Thor and Muskwa, and they stopped.
