“No-no! Are you mad?” returned Helen. “The bear will kill Pedro.” “He might kill you.” “You ride that way and yell for Dale,” rejoined Bo. “What will--you do?” gasped Helen. “I'll shoot at the bear--scare him off. If he chases me he can't catch me coming downhill. Dale said that.” “You're crazy!” cried Helen, as Bo looked up the slope, searching for open ground. Then she pulled the rifle from its sheath. But Bo did not hear or did not care. She spurred the mustang, and he, wild to run, flung grass and dirt from his heels. What Helen would have done then she never knew, but the fact was that her horse bolted after the mustang. In an instant, seemingly, Bo had disappeared in the gold and green of the forest slope. Helen's mount climbed on a run, snorting and heaving, through aspens, brush, and timber, to come out into a narrow, long opening extending lengthwise up the slope. A sudden prolonged crash ahead alarmed Helen and halted her horse. She saw a shaking of aspens. Then a huge brown beast leaped as a cat out of the woods. It was a bear of enormous size. Helen's heart stopped--her tongue clove to the roof of her mouth. The bear turned. His mouth was open, red and dripping. He looked shaggy, gray. He let out a terrible bawl. Helen's every muscle froze stiff. Her horse plunged high and sidewise, wheeling almost in the air, neighing his terror. Like a stone she dropped from the saddle. She did not see the horse break into the woods, but she heard him. Her gaze never left the bear even while she was falling, and it seemed she alighted in an upright position with her back against a bush. It upheld her. The bear wagged his huge head from side to side. Then, as the hound barked close at hand, he turned to run heavily uphill and out of the opening. The instant of his disappearance was one of collapse for Helen. Frozen with horror, she had been unable to move or feel or think. All at once she was a quivering mass of cold, helpless flesh, wet with perspiration, sick with a shuddering, retching, internal convulsion, her mind liberated from paralyzing shock. The moment was as horrible as that in which the bear had bawled his frightful rage. A stark, icy, black emotion seemed in possession of her. She could not lift a hand, yet all of her body appeared shaking. There was a fluttering, a strangling in her throat. The crushing weight that surrounded her heart eased before she recovered use of her limbs. Then, the naked and terrible thing was gone, like a nightmare giving way to consciousness. What blessed relief! Helen wildly gazed about her. The bear and hound were out of sight, and so was her horse. She stood up very dizzy and weak. Thought of Bo then seemed to revive her, to shock different life and feeling throughout all her cold extremities. She listened.
