"At the sound of her voice, the dog, who had been trying to get at the hat, commenced his manoeuvers to attract her across the gorge, bounding ahead, calling her with his short, excited barks, and making all the signs of a hunting dog impatient to lead to the quarry. She tried to get to her feet, but I put my hand on her shoulder. 'Wait, madam,' I said. 'You must rest a little longer before you try to start back. You were so tired you fainted. And your eyes must have played you a trick.' "'You mean,' she began and stopped. "I am not much of a dissembler, and I found it hard to meet her look, but I answered with all the assurance I could muster. 'I mean, madam, you are mistaken about that hat.' "She waited a moment, watching the setter, then her glance moved back incredulously to me. 'Then what excites Jerry?' she asked. "'Why,' I hurried to answer, 'just another bunch, of ptarmigan, probably. But while you are resting here, I will go over into that pocket to satisfy him.' "The setter, content with my company, ran ahead, and I followed him across the ice-bridge. The pocket was thickly strewn with broken rock, but at the upper end there was a clear space grown with heather. And it was there, as I feared, between a bluff and a solitary thumb-shaped boulder that the dog had found his master." Tisdale paused, looking off again with clouding brows to the stormy heights. Eastward the moon in a clear sky threw a soft illumination on the desert. The cry of the cougar had ceased. The electrical display was less brilliant; it seemed farther off. Miss Armitage moved a little and waited, watching his face. "But of course," she ventured at last, "you mixed another draught from your emergency flask. The stimulant saved his life."
