"When next the moon is full," he said, "the Showut Poche-dakas will observe the Fiesta de Santa Maria de Refugio, as taught them years ago by the padres who came from Spain. Then will the Showut Poche-dakas dance the fire dance, which is according to the laws laid down by the wise men of their ancestors. Ride here to the Fiesta de Santa Maria de Refugio on the first night that the moon is full. _Adios, amigo!_" That was all; and Oliver had passed out into the bright sunlight and found Jessamy Selden. The two had talked over the circumstances often since that day, but neither could throw any light on the matter. But the first night of the full moon was not far distant now, and Oliver and the girl were awaiting it impatiently. Oliver felt that at the fiesta he would in some way gain an inkling of the mysterious question that had puzzled his father for thirty years, and which eventually had brought his son into this country to find out whether its answer was Yes or No. Oliver tilted back his chair and lighted his briar pipe. Out in the liveoak tree the linnet waited, head on one side, chirping plaintively occasionally, for the renewed clicking of the typewriter keys. But Oliver's thoughts were far from his work. That burning, colourless liquor that had so fiercely fired his brain was undoubtedly moonshine--and redistilled at that, no doubt. Jessamy had told him further that she had not so much as unscrewed the cap since old Adam had given her the flask, at her request, and had had no idea that the flask had not contained amber-coloured whisky. Was this in reality the reason why the Poison Oakers wished him to be gone? Had they been distilling moonshine whisky down at Sulphur Spring to supply the blind pigs controlled by the prosecuting attorney at the county seat? And had his inadvertent shutting off of Sulphur Spring's supply of water stopped their illicit activities? They had known, perhaps, that eventually he would discover that his own spring had been choked by some one and would rectify the condition. Whereupon Sulphur Spring would cease to flow and automatically cut off one of their sources of revenue. Oliver decided to look for Sulphur Spring at his earliest opportunity. His brows came together as he recalled the episode on the hill, when either the fiery raw liquor or the poison from the diamond-back's fangs--or both--had deprived him of his senses. He remembered perfectly what he had said--what he had done. He had heard sometime that a man always tells the truth when he is drunk. But had he been drunk, or rabid from the hypodermic injections of Showut Poche-daka? Or, again--both? One thing he knew--that he thrilled yet at remembrance of those satin lips which he had pressed again and again. Had he told the truth? Had he said that day what he would not have revealed for anything--at that time?
