"'If you insist.' I gave in reluctantly. 'Of course I'll put myself at your service. We'll look for him to-morrow.' All sorts of wild expedients to thwart a meeting were scurrying through my mind. "'We'll go to-day,' said she. "'But--' "'At once! If you're too busy I'll ask somebody else--' "'Very well!' said I. 'We'll drive out to the encampment.' And I sent for my buckboard. "I was delayed in spite of myself until nearly sundown, and meanwhile Alicia Harman waited in my office, pacing the floor with ill-concealed impatience. Before starting I ventured one more remonstrance, for I was filled with misgivings, and the more I saw of this girl the more fantastic and unnatural this affair seemed. But the unbridled impulses of her parents were bearing fruit, and no one could say her nay. She afforded the most illuminating study in heredity that I have ever witnessed. "We didn't say much during our fifteen-mile drive, for I was worried and Alicia was oddly torn between apprehension and exultation. We had left the French maid behind. I don't know that any woman ever went to her lover under stranger circumstances or in greater perturbation of spirit than did this girl, behind whom lay a generation of selfishness and unrestraint.

In the daylight it would have been sufficiently picturesque, but under the wizard hand of the darkness it became ten times more so. "When I finally tied my horses and led the girl into the heart of it I think she became a bit frightened, for these Indians were the Sioux of a bygone day. They were barbaric in dress and in demeanor. "I guided her through the tangle of tepees, through glaring fire-lit circles and through black voids where we stumbled and had to feel our way. We were jostled and elbowed by fierce warriors and by sullen squaws. At every group I asked for Running Elk, but he was merely one of five thousand and nobody knew his whereabouts. "The people have ever been jealous of their customs, and as a result we were frequently greeted by cold looks and sudden silences. Recognizing this open resentment, my companion let down a thick automobile veil which effectually hid her face. Her dust-coat was long and loose and served further to conceal her identity. "At one time we came upon a sight I would gladly have spared her--the spectacle of some wrinkled hags strangling a dog by the light of a fire. The girl at my side stifled a cry at the apparition. "'What are they doing?' she gasped. "'Preparing the feast,' I told her. "'Do they--really--'
