Round the camp, during the night, the cayeute keeps unremitting watch, and the traveler not unfrequently starts from his bed with affright, as the mournful and unearthly chiding of the wolf breaks suddenly upon his ear: the long-drawn howl being taken up by others of the band, until it dies away in the distance, or some straggler passing within hearing answers to the note, and howls as he lopes away. Our party crossed the south fork about ten miles from its juncture with the main stream, and then, passing the prairie, struck the north fork a day's travel from the other. At the mouth of an ash-timbered creek they came upon Indian "sign," and as now they were in the vicinity of the treacherous Sioux, they moved along with additional caution, Frapp and Gonneville, two experienced mountaineers, always heading the advance. About noon they had crossed over to the left bank of the fork, intending to camp on a large creek where some fresh beaver sign had attracted the attention of some of the trappers; and as, on further examination, it appeared that two or three lodges of that animal were not far distant, it was determined to remain here a day or two, and set their traps. Gonneville, old Luke, and La Bonté, had started up the creek, and were carefully examining the banks for sign, when the former, who was in front, suddenly paused, and, looking intently up the stream, held up his hand to his companions to signal them to stop. Luke and La Bonté both followed the direction of the trapper's intent and fixed gaze. The former uttered in a suppressed tone the expressive exclamation, Wagh!--the latter saw nothing but a wood-duck swimming swiftly down the stream, followed by her downy progeny. Gonneville turned his head, and, extending his arm twice with a forward motion up the creek, whispered, "Les sauvages." "Injuns, sure, and Sioux at that," answered Luke. Still La Bonté looked, but nothing met his view but the duck with her brood, now rapidly approaching; and as he gazed, the bird suddenly took wing, and, flapping on the water, flew a short distance down the stream and once more settled on it. "Injuns?" he asked; "where are they?" "Whar?" repeated old Luke, striking the flint of his rifle, and opening the pan to examine the priming. "What brings a duck a-streakin' it down stream if humans ain't behint her? and who's thar in these diggins but Injuns, and the worst kind? and we'd better push to camp, I'm thinking, if we mean to save our hair."
