It was plain to Calumet that she was badly hurt over the dog's death. Certainly, despite her cold composure, she must be filled with rage against him for killing the animal. He might now have exhibited his arm, to confound her with the evidence of his innocence of wantonness, and very probably she would have been instantly remorseful. But he had no such intention; he was keenly alive to his opportunity to show her that he was answerable to no one for his conduct. He enjoyed her chagrin; he was moved to internal mirth over her impotent wrath; he took a savage delight in seeing her cringe from the evidence of his apparent brutality. He grinned at her. "He's dead, ain't he?" he said. "An' I ain't makin' no excuses to you!" She gave him a scornful glance and went over to Malcolm, who had clambered to his feet and was crouching, his face working with passion. At the instant Betty reached him he was clawing at his six-shooter, trying to drag it from the holster. But Betty's hand closed over his and he desisted. "Not that, grandpa," she said quietly. "Shooting won't bring Lonesome back. Besides"--she turned toward Calumet and saw the cold grin on his face as his right hand dropped to his hip in silent preparation for Malcolm's menacing movement--"don't you see that he would shoot you as he shot Lonesome? He just can't help being a brute!" She turned her back to Calumet and spoke in a low voice to her grandfather, smoothing his hair, patting his shoulders--calming him with all a woman's gentle artifices. And Calumet stood watching her, marveling at her self-control, feeling again that queer, thrilling sensation of reluctant admiration. He had forgotten Bob. Betty had left the boy standing alone when she had gone over to Malcolm, and Bob had hobbled forward when Calumet had turned to follow the girl's movements, so that now he stood just behind Calumet. The latter became aware of the boy's presence when the latter seized his left hand from behind, and he turned with a snarl, his six-shooter half drawn, to confront the boy, whose grip on the hand had not been loosened. Calumet drew the hand fiercely away, overturning Bob so that he fell sprawling into the dust at his feet. The youngster was up again before Betty and Malcolm could reach him, hobbling toward Calumet, his thin face working from excitement, his big eyes alight over the discovery he had made. "He didn't kill Lonesome because he is mean, Betty!" he shrilled; "I knew he didn't! Look at his arm, Betty! It's all bloody! Lonesome bit him!" In spite of Calumet's efforts to avoid him, the boy again seized the arm, holding it out so that Betty and Malcolm could see the patches on the sleeve and the thin red streak that had crawled down over the back of his hand and was dripping from the finger tips.
