Straight at the man it shot, and as it reached him he sprang aside.

The same mischance that had upset the animal now proved the undoing of the man's well-aimed thrust. As he drew back his arm to strike, Polaris felt his feet flying from under him.

By exercising all of his tigerish agility he prevented himself from rolling right under the ponderous body of his antagonist. Backward he threw himself, struck a softer spot in the snow crust, and disappeared in it up to his shoulders.

Had Bruin stopped to consider his predicament, that would have been a tight situation for Polaris; but the enraged mountain of flesh paid no further attention to him. Instead he scrambled to his feet at the foot of the slope, snarling more viciously than ever because of his downfall, and charged on into the group of Sardanians.

Before they could realize what was happening, and that Polaris had failed to wound or turn the animal, he was upon them. They scattered, thrusting their spears as they leaped from the path of the monster.

One of them, Kard the Smith, was not so fortunate as the rest. He stood directly in the path of the charge. As he leaped to one side a huge paw whirled in the air and one of the curved talons caught in the slack of his rough tunic, hurling him down as a mouse is spun from the claw of a cat. Before his companions could return to his aid the bear was tearing at the prostrate body of the smith.

As soon as he fell through the snow crust Polaris threw himself forward on his face along the surface, seeking a spot that would allow him to stand upright. In an instant he was on his feet and forward in the wake of the furious bear. His spear had fallen from his hand when he broke into the soft snow, and had glided away over the glary crust for many feet. There was no time to regain it if he was to aid Kard. Plucking the knife from his belt, he rushed in.

Seeming to sense the new danger, the bear whirled on its haunches, and, holding the body of the Sardanian beneath it with one forepaw, struck out madly at Polaris with the other.

Polaris evaded the sweep of the blow by the smallest margin. He had thrown off his gloves, and he caught the long hair on the flail-like paw with his left hand. As the bear drew in his paw to deliver another buffet, the man came with it.

Never in all his bear fights had he come to grips with one of the antarctic monarchs from the front in this wise; but there was no help for it if he would save the smith. He was swept in against the wide chest of the animal, and its terrible front paws were closed to crush him as it raised one armed hind leg to rip him with its down-stroke, and at the same time strove to bend its head down and tear with its jaws.
