He did not need eyes to follow the trail.  It was warm under his nose, and he started in the zigzag ascent of the mountain as fast as he could go.  There were places where progress was difficult for his short legs, but he kept on valiantly and hopefully, encouraged by Thor’s fresh scent.

It took him a good hour to reach the beginning of the naked shale that reached up to the belt of snow and the sky-line, and it was four o’clock when he started up those last three hundred yards between him and the mountain-top.  Up there he believed he would find Thor.  But he was afraid, and he continued to whimper softly to himself as he dug his little claws bravely into the shale.

Muskwa did not look up to the crest of the peak again after he had started.  To have done that it would have been necessary for him to stop and turn sidewise, for the ascent was steep.  And so, when Muskwa was halfway to the top, it happened that he did not see Langdon and Bruce as they came over the sky-line; and he could not smell them, for the wind was blowing up instead of down.  Oblivious of their presence he came to the snow-belt.  Joyously he smelled of Thor’s huge footprints, and followed them.  And above him Bruce and Langdon waited, crouched low, their guns on the ground, and each with his thick flannel shirt stripped off and held ready in his hands.  When Muskwa was less than twenty yards from them they came tearing down upon him like an avalanche.

Not until Bruce was upon him did Muskwa recover himself sufficiently to move.  He saw and realized danger in the last fifth of a second, and as Bruce flung himself forward, his shirt outspread like a net, Muskwa darted to one side.  Sprawling on his face, Bruce gathered up a shirtful of snow and clutched it to his breast, believing for a moment that he had the cub, and at this same instant Langdon made a drive that entangled him with his friend’s long legs and sent him turning somersaults down the snow-slide.

Muskwa bolted down the mountain as fast as his short legs could carry him.  In another second Bruce was after him, and Langdon joined in ten feet behind.

Suddenly Muskwa made a sharp turn, and the momentum with which Bruce was coming carried him thirty or forty feet below him, where the lanky mountaineer stopped himself only by doubling up like a jack-knife and digging toes, hands, elbows, and even his shoulders in the soft shale.

Langdon had switched, and was hot after Muskwa.  He flung himself face downward, shirt outspread, just as the cub made another turn, and when he rose to his feet his face was scratched and he spat half a handful of dirt and shale out of his mouth.

Unfortunately for Muskwa his second turn brought him straight down to Bruce, and before he could turn again he was enveloped in sudden darkness and suffocation, and over him there rang out a fiendish and triumphant yell.

“I got ’im!” shouted Bruce.
