"Got 'em!" Bud answered. "Soon as we saw the fire I went to where they had them tethered and led 'em over here. There they are, by that tree. Say, I wonder who started this thing?" "What makes you think someone started it?" Hawkins asked, looking at him closely. "Well, I figure it couldn't set itself--and it's not likely an accident would happen." "Can't tell--like as not a lamp turned over. Wow, look at that roof go! Where can those birds be keeping themselves? What chance have they got now?" "Probably trying to put it out from inside. Foolish thing to do, but they know as soon as they come out they're finished. I wouldn't deliberately set the place on fire, but it sure solved our problem for us." As the fire raged more fiercely, the ranchers looked at each other. What had happened to Delton? Could it be that he determined to stick it out until the last moment, and risk a horrible death? Surely he must realize that in peaceful surrender lay his only hope. Suddenly Bud uttered a cry. "Here comes someone! Out of the cellar! Look!" Running toward them was a bedraggled figure. Clothes torn, face blackened with smoke, it presented a truly pitiful picture. As it ran it waved its arms wildly. Something in the appearance, or possibly its gesture, caused Bud to exclaim: "Say, he looks familiar! Kid, Nort--know who that is?" The boys looked curiously at the wretched man. Now he was almost upon them, and they could see his eyes glaring wildly. He reached them and fell to the ground, exhausted. Bud dismounted quickly and bent over him. "Get up!" he commanded. "Let's have a look at you!" The man dragged himself to his feet. At a sight of his face, blackened as it was by the smoke, all started back. "Well, what do you know about that!" the Kid cried. "It's our Mexican cook!" "What are you doing here?" Nort asked sharply. "You with Delton? Hey? Tell the truth now or I'll hit you!" "He can't talk!" Bud protested. "Give him a chance. He's all in. Come here, Mex." The boy held out his arm and the Mexican seized it and steadied himself. "Were you with Delton?" Bud asked. The Mexican shook his head negatively. Then he pointed to the burning building and waved his arms wildly. "Steady up!" Bud commanded. "Take it easy!" The man took a deep breath and regained control of himself. But his gestures were still inexplainable. After a minute of vain gesticulating the Kid suddenly exclaimed: "I think I get it! Mex, listen here: Did you set that fire?" A vigorous nod of the head. The boys looked at each other in surprise. "What for?" The Mexican pointed to himself, then held up two fingers. Then he pointed to the house, and shook his fist. "Be means his brother!" the Kid said. "What about him, Mex? Did Delton get hold of him?" Another nod, and more furious gestures. "I see!" cried the Kid. "He means Delton put his brother up to some dirty work. That right, Mex?" Eagerly the man signified yes.
