"Alfred said he hadn't seen even a teepee-trail, and that they must be all up hunting buffalo. Besides that, you don't imagine for a moment that your father would take you all this way to Deadwood just for a lark, if there was the slightest danger, do you?" "I don't know; I made him." She looked out over the long sweeping descent to which they were coming, and the long sweeping ascent that lay beyond. The breeze and the sun played with the prairie grasses, the breeze riffling them over, and the sun silvering their under surfaces thus exposed. It was strangely peaceful, and one almost expected to hear the hum of bees as in a New England orchard. In it all was no sign of life. "We'd get lost," she said, finally. "Oh, no, we wouldn't!" he asserted with all the eagerness of the amateur plainsman. "I've got that all figured out. You see, our train is going on a line with that butte behind us and the sun. So if we go ahead, and keep our shadows just pointing to the butte, we'll be right in their line of march." He looked to her for admiration of his cleverness. She seemed convinced. She agreed, and sent him back to her wagon for some article of invented necessity. While he was gone she slipped softly over the little hill to the right, cantered rapidly over two more, and slowed down with a sigh of satisfaction. One alone could watch the directing shadow as well as two. She was free and alone. It was the one thing she had desired for the last six days of the long plains journey, and she enjoyed it now to the full. No one had seen her go. The drivers droned stupidly along, as was their wont; the occupants of the wagons slept, as was their wont; and the diminutive Alfred was hiding his blushes behind clouds of dust in the rear, as was not his wont at all. He had been severely shocked, and he might have brooded over it all the afternoon, if a discovery had not startled him to activity. On a bare spot of the prairie he discerned the print of a hoof. It was not that of one of the train's animals. Alfred knew this, because just to one side of it, caught under a grass-blade so cunningly that only the little scout's eyes could have discerned it at all, was a single blue bead. Alfred rode out on the prairie to right and left, and found the hoof-prints of about thirty ponies. He pushed his hat back and wrinkled his brow, for the one thing he was looking for he could not find--the two narrow furrows made by the ends of teepee-poles dragging along on either side of the ponies. The absence of these indicated that the band was composed entirely of bucks, and bucks were likely to mean mischief. He pushed ahead of the whole party, his eyes fixed earnestly on the ground. At the top of the hill he encountered the young Easterner. The latter looked puzzled, in a half-humourous way.
