“Pretend not to see them; keep on dancing,” he hissed in her ear. He had no distinct plan in what he said, but spoke merely from an instinct of self-preservation, which told him that when they stopped, the Indians would be upon them. But as she mechanically, and really more dead than alive, obeyed his direction and resumed the dance, and he in his excitement was treading on her feet at every step, the thought flashed upon him that there was a bare chance of escaping violence, if they could keep the Indians interested without appearing to notice their presence. In successive whispers he communicated his idea to Miss Dyer: “Don't act as if you saw them at all, but do everything as if we were alone. That will puzzle them, and make them think us supernatural beings, or perhaps crazy: Indians have great respect for crazy people. It's our only chance. We will stop dancing now, and sing awhile. Give them a burlesque of opera. I 'll give you the cues and show you how. Don't be frightened. I don't believe they 'll touch us so long as we act as if we did n't see them. Do you understand? Can you do your part?” “I understand; I 'll try,” she whispered. “Now,” he said, and as they separated, he threw his hat on the ground, and, assuming an extravagantly languishing attitude, burst forth in a most poignant burlesque of a lovelorn tenor's part, rolling his eyes, clasping his hands, striking his breast, and gyrating about Miss Dwyer-in the most approved operatic style. He had a fine voice and knew a good deal of music; so that, barring a certain nervousness in the performer, the exhibition was really not bad. In his singing he had used a meaningless gibberish varied with the syllables of the scale, but he closed by singing the words, “Are you ready now? Go ahead, then.” With that she took it up, and rendered the prima donna quite as effectively, interjecting “The Last Rose of Summer” as an aria in a manner that would have been encored in San Francisco. He responded with a few staccato notes, and the scene ended by their rushing into each other's arms and waltzing down the stage with abandon. The Indians sat motionless on their horses, not even exchanging comments among themselves. They were evidently too utterly astonished by the goings on before them to have any other sentiment as yet beyond pure amazement. Here were two richly-dressed pale-faces, such as only lived in cities, out in the middle of an uninhabitable desert, in the freezing midnight, having a variety and minstrel show all to themselves, and, to make the exhibition the more unaccountable, without apparently seeing their auditors at all. Had they started up the show after being captured, Indian cunning would have recognized in it a device to save their lives, but the two had been at it before the party rode up,-- had, in fact, first attracted attention by their gyrations, which were visible for miles out on the moony plain.
