“Yes, I—I only hope we—we get stunned when we fall,” replied Jim, his voice breaking. “The—then we won’t suffer so much.”

Scarcely had he spoken when the bear again threw himself at the rock. With a crackling of ice the bowlder gave and swayed perilously. The boys clutched wildly at the ice-filled crevices. They knew that one more such effort on the part of the bear would send the rock crashing over.

And then a new light came into their eyes, their hearts beat faster. From beyond the next ridge had come the sound of yelping dogs, the shrill shout of an Eskimo.

The bear, despite his rage, had heard it too. With lowered head and swaying neck he stood listening. The next instant the galloping dogs swung over the ridge. Behind them came the sledge with a fur-clad figure shouting and brandishing the long whip. At the top of their lungs the boys screamed, shouted and yelled. Forgetting their precarious position, they leaped to their feet and waved their arms. Unavik’s sharp eyes had taken in the situation at a glance. Midway in its mad career, he overturned the sledge and swung it sidewise. The dogs, suddenly arrested in their race, tumbled head over heels, and the next second, Unavik was among them, slashing through the thongs and traces and shouting commands.

Already the scent of the bear had reached the dogs’ nostrils. With stiff hairs bristling on their shoulders they hurled themselves forward. Like a pack of great, tawny wolves they came plunging towards the bear. At their heels came Unavik, his old musket in his hands. As the bear turned to face the snapping, snarling, savage ring of big dogs, the Eskimo approached within a dozen feet, raised his heavy 50-caliber Remington and fired at the bear’s broad chest.

With a gurgling roar the great beast lurched forward, struck wildly with his paws at the dogs and sank lifeless on the snow.

“Gee Christopher!” cried Tom, as the two boys scrambled from their perch. “It was lucky you came, Unavik. Another minute and we’d have been killed.”

The Eskimo grinned. “Sure Mike!” he replied. “How you feller likeum hunt bear?”

“We didn’t,” declared Jim. “He hunted us. My, but isn’t he a whopper!”

“Mos’ big all same Ukla, me say,” agreed Unavik. “Why you no killum?”
