Approaching, he sought by instinct the cover of trees and bush-clumps, moving smoothly and noiselessly; Jager had been noted during his service in the Army of the Frontier for his ability to scout at night, an ability which he credited to the fact that he had been born in the darkest hours. He made almost as good progress as though he had been moving in broad daylight. At eleven o'clock sharp, as he guessed--like many men who never carry watches, he had become good at judging the time--he was within two hundred yards of the rock itself, and cover had run out. There he paused, chin-deep in a clump of early weeds. Lanark and the girl, as he surmised, must be well into the gulley by this time. He, Jager, smiled as he remembered with what alacrity Lanark had accepted the assignment of bodyguard to Enid Mandifer. Those two young people acted as if they were on the brink of falling in love, and no mistake.... His eyes were making out details of the scene ahead. Was even the full moon so bright as all this? He could not see very clearly the ruined foundations, for they sat in a depression of the earth. Yet there seemed to be a clinging blue light at about that point, a feeble but undeniable blue. Mentally he compared it to deep, still water, then to the poorest of skimmed milk. Jager remembered the flames that once had burned there, blue as amethyst. But the blue light was not solid, and it had no heat. Within it, dimmed as though by mist, stood and moved--figures. They were human, at least they were upright; and they stood in a row, like soldiers, all but two. That pair was dark-seeming, and one was grossly thick, the other thin as an exclamation point. The line moved, bent, formed a weaving circle which spread as its units opened their order. Jager had never seen such a maneuver in four years of army service. Now the circle was moving, rolling around; the figures were tramping counter-clockwise--"withershins" was the old-fashioned word for that kind of motion, as Jager remembered from his boyhood in Pennsylvania. The two darker figures, the ones that had stood separate, were nowhere to be seen; perhaps they were inclosed in the center of the turning circle, the moving shapes of which numbered six. There had been six of Quantrill's guerrillas that died in almost that spot. The ground was bare except for spring grass, but Jager made shift to crawl forward on hands and knees, his eyes fixed on the group ahead, his beard bristling nervously upon his set chin. He crept ten yards, twenty yards, forty. Some high stalks of grass, killed but not leveled by winter, afforded him a bit of cover, and he paused again, taking care not to rustle the dry stems. He could see the maneuvering creatures more plainly.
