"It's Lonesome!" gasped Malcolm, his lips quivering as he looked at the beast; "Bob's Lonesome!" Calumet flashed around at him, cursing savagely. "What you gettin' at, you damned old gopher?" he sneered. "It's Lonesome!" repeated Malcolm, his weather-lined face red with resentment and anger. He showed no fear of Calumet now, but came close to him and stood rigid, his hands clenched. "It's Lonesome!" he repeated shrilly; "Bob's Lonesome!" And then, seeing from the expression of Calumet's face that he did not comprehend, he added: "It's Bob's dog, Lonesome! Bob loved him so, an' now you've gone an' killed him--you--you hellhound! You--" His quavering voice was cut short; once more his throat felt the terrible pressure of Calumet's iron fingers. For an instant he was held at arm's length, shaken savagely, and in the next he was flung with furious force against the corral fence, from whence he staggered and fell into a corner. Calumet turned from him to confront Betty. Her eyes were ablaze, and one hand rested with unconscious affection on Bob's head as the boy stood looking down at the body of the dog, sobbing quietly. Betty was trying to keep her composure, but at her first words her voice trembled. "So you've killed Lonesome," she said. Calumet had finished reloading his pistol, and he folded his arms over his chest, deliberately shielding the left, which Lonesome had bitten, thus hiding the red patches that showed on the shirt sleeve over the wound. He would not give Betty the satisfaction of seeing that he had been hurt. "Lonesome," explained Betty, frigidly, "was a dog--he was Bob's dog. Bob loved him. I suppose you didn't know that--you couldn't have known. We believed him to be part wolf. Bob found him on the Lazette trail, where he had evidently been left behind, probably forgotten, by some traveler who had camped there. Bob brought him home and raised him. He has never been known to exhibit any vicious traits. You were born in the West," she went on, "and ought to be able to tell the difference between a dog and a wolf. Did you take Lonesome for a wolf?" "I reckon," sneered Calumet, determined not to be lectured by her, "that I've got to give a reason for everything I do around here. Even to killin' a damn dog!" "Then," she said with cold contempt, "you killed him in pure wantonness?"
