and lay squat out in the sunshine on their rocks; the eagles soared so high above the peaks that they were mere dots; the hawks, with meat-filled crops, had disappeared into the timber; goat and sheep were lying down far up toward the sky-line, and if there were any grazing animals near they were well fed and napping.

The mountain hunter knew that this was the hour when he should scan the green slopes and the open places between the clumps of timber for bears, and especially for flesh-eating bears.

It was Thor's chief prospecting hour. Instinct told him that when all other creatures were well fed and napping he could move more openly and with less fear of detection. He could find his game, and watch it. Occasionally he would kill a goat or a sheep or a caribou in broad daylight, for over short distances he could run faster than either a goat or a sheep, and as fast as a caribou. But chiefly he killed at sunset or in the darkness of early evening.

Thor rose from beside the rock with a prodigious whoof that roused Muskwa. The cub got up, blinked at Thor and then at the sun, and shook himself until he fell down.

Thor eyed the black and tan mite a bit sourly. After the sapoos oowin he was craving red, juicy flesh, just as a very hungry man yearns for a thick porterhouse instead of lady fingers or mayonnaise salad—flesh and plenty of it; and how he could hunt down and kill a caribou with that half-starved but very much interested cub at his heels puzzled him.

Muskwa himself seemed to understand and answer the question. He ran a dozen yards ahead of Thor, then stopped and looked back impudently, his little ears perked forward, and with the look in his face of a small boy proving to his father that he is perfectly qualified to go on his first rabbit hunt.

With another whoof Thor started along the slope in a spurt that brought him up to Muskwa immediately, and with a sudden sweep of his right paw he sent the cub rolling a dozen feet behind him, a manner of speech that said plainly enough, "That's where you belong if you're going hunting with me!"

Then Thor lumbered slowly on, eyes and ears and nostrils keyed for the hunt. He descended until he was not more than a hundred yards above the creek, and he no longer sought out the easiest trail, but the rough and broken places. He travelled slowly and in a zigzag fashion, stealing cautiously around great masses of boulders, sniffing up each coulee that he came to, and investigating the timber clumps and windfalls.

At one time he would be so high up that he was close to the bare shale, and again so low down that he walked in the sand and gravel of the creek. He caught many scents in the wind, but none that held or deeply interested him. Once, up near the shale, he smelled goat; but he never went above the shale for meat. Twice he smelled sheep, and late in the afternoon he saw a big ram looking down on him from a precipitous crag a hundred feet above.

Lower down his nose touched the trails of porcupines, and often his head hung over the footprints of caribou as he sniffed the air ahead.

There were other bears in the valley, too. Mostly these had travelled along the creek-bottom, showing they were blacks or cinnamons. Once Thor struck the scent of another grizzly, and he rumbled ill-humouredly.

Not once in the two hours after they left the sunrock did Thor pay any apparent attention to Muskwa, who was growing hungrier and weaker as the day lengthened. No boy that ever lived was gamer than the little tan-faced cub. In the rough places he stumbled and fell frequently; up places that Thor could make in a single step he had to fight desperately to make his way; three times Thor waded through the creek and Muskwa half drowned himself in following; he was battered and bruised and wet and his foot hurt him—but he followed. Sometimes he was close to Thor, and at others he had to run to catch up. The sun was setting when Thor at last found game, and Muskwa was almost dead.

He did not know why Thor flattened his huge bulk suddenly alongside a rock at the edge of a rough meadow, from which they could look down into a small hollow. He wanted to whimper, but he was afraid. And if he had ever wanted his mother at any time in his short life he wanted her now. He could not understand why she had left him among the rocks and had never come back; that tragedy Langdon and Bruce were to discover a little later. And he could not understand why she did not come to him now. This was just about his nursing hour before going to sleep for the night, for he was a March cub, and, according to the most approved mother-bear regulations, should have had milk for another month.
