Here, in a small enclosure with rails much higher than the other corrals, stood Satan, and Black Bart made straight for the stallion. He was seen from afar, and the black horse stood waiting, his head thrown high in the air, his ears pricking forward, the tail flaunting, a picture of expectancy. So under the lower rail Bart slunk and stood under the head of Satan, growling terribly. Of this display of anger the stallion took not the slightest notice, but lowered his beautiful head until his velvet nose touched the cold muzzle of Bart. There was something ludicrous about the greeting--it was such an odd shade close to the human. It was as brief as it was strange, for Black Bart at once whirled and trotted away towards the barns. By the time Doctor Byrne and Whistling Dan caught up with him, the wolf-dog was before the heaps and ashes which marked the site of the burned barn. Among these white and grey and black heaps he picked his way, sniffing hastily here and there. In the very centre of the place he sat down suddenly on his haunches, pointed his nose aloft, and wailed with tremendous dreariness. "Now," murmured the doctor to Dan, "that strikes me as a singular manifestation of intelligence in an animal--he has found the site of the very barn where he was hurt--upon my word! Even fire doesn't affect his memory!" Here he observed that the face of Whistling Dan had grown grim. He ran to Bart and crouched beside him, muttering; and Byrne heard. "That's about where you was lyin'," said Dan, "and you smell your own blood on the ground. Keep tryin', Bart. They's something else to find around here." The wolf-dog looked his master full in the face with pricking ears, whined and then started off sniffling busily at the heaps of ashes. "The shooting of the dog is quite a mystery," said Byrne, by way of conversation. "Do you suppose that one of the men from the bunk-house could have shot him?" But Dan seemed no longer aware of the doctor's presence. He slipped here and there with the wolf-dog among the ash-heaps, pausing when Bart paused, talking to the brute continually. Sometimes he pointed out to Bart things which the doctor did not perceive and Bart whined with a terrible, slavering, blood-eagerness. The wolf-dog suddenly left the ash-heaps and now darted in swiftly entangled lines here and there among the barns. Dan Barry stood thoughtfully still, but now and then he called a word of encouragement.
