Almost instantly there was a terrific crack out in the middle of the pond, followed by a tremendous splash. An old beaver had seen Thor and with the flat side of his broad tail had given the surface of the water a warning slap that cut the still air like a rifle-shot. All at once there were splashings and divings in every direction, and a moment later the pond was ruffled and heaving as a score of interrupted workers dove excitedly under the surface to the safety of their brush-ribbed and mud-plastered strongholds, and Muskwa was so absorbed in the general excitement that he almost forgot to follow Thor.
He overtook the grizzly at the dam. For a few moments Thor inspected the new work, and then tested it with his weight. It was solid, and over this bridge ready built for them they crossed to the higher ground on the opposite side. A few hundred yards farther on Thor struck a fairly well-beaten caribou trail which in the course of half an hour led them around the end of the lake to the outlet stream flowing north.
Every minute Muskwa was hoping that Thor would stop. His afternoon's nap had not taken the lameness out of his legs nor the soreness from the tender pads of his feet. He had had enough, and more than enough, of travel, and could he have regulated the world according to his own wishes he would not have walked another mile for a whole month. Mere walking would not have been so bad, but to keep up with Thor's ambling gait he was compelled to trot, like a stubby four-year-old child hanging desperately to the thumb of a big and fast-walking man. Muskwa had not even a thumb to hang to. The bottoms of his feet were like boils; his tender nose was raw from contact with brush and the knife-edged marsh grass, and his little back felt all caved in. Still he hung on desperately, until the creek-bottom was again sand and gravel, and travelling was easier.
The stars were up now, millions of them, clear and brilliant; and it was quite evident that Thor had set his mind on an "all-night hike," a kuppatipsk pimootao as a Cree tracker would have called it. Just how it would have ended for Muskwa is a matter of conjecture had not the spirits of thunder and rain and lightning put their heads together to give him a rest.
For perhaps an hour the stars were undimmed, and Thor kept on like a heathen without a soul, while Muskwa limped on all four feet. Then a low rumbling gathered in the west. It grew louder and louder, and approached swiftly—straight from the warm Pacific. Thor grew uneasy, and sniffed in the face of it. Livid streaks began to criss-cross a huge pall of black that was closing in on them like a vast curtain. The stars began to go out. A moaning wind came. And then the rain.
Thor had found a huge rock that shelved inward, like a lean-to, and he crept back under this with Muskwa before the deluge descended. For many minutes it was more like a flood than a rain. It seemed as though a part of the Pacific Ocean had been scooped up and dropped on them, and in half an hour the creek was a swollen torrent.
The lightning and the crash of thunder terrified Muskwa. Now he could see Thor in great blinding flashes of fire, and the next instant it was as black as pitch; the tops of the mountains seemed falling down into the valley; the earth trembled and shook—and he snuggled closer and closer to Thor until at last he lay between his two forearms, half buried in the long hair of the big grizzly's shaggy chest. Thor himself was not much concerned in these noisy convulsions of nature, except to keep himself dry. When he took a bath he wanted the sun to be shining and a nice warm rock close at hand on which to stretch himself.
For a long time after its first fierce outbreak the rain continued to fall in a gentle shower. Muskwa liked this, and under the sheltering rock, snuggled against Thor, he felt very comfortable and easily fell asleep. Through long hours Thor kept his vigil alone, drowsing now and then, but kept from sound slumber by the restlessness that was in him.
It stopped raining soon after midnight, but it was very dark, the stream was flooding over its bars, and Thor remained under the rock. Muskwa had a splendid sleep.
Day had come when Thor's stirring roused Muskwa. He followed the grizzly out into the open, feeling tremendously better than last night, though his feet were still sore and his body was stiff.
