We were now arrived at the close of our solitary journeyings along the St. Joseph’s trail. On the evening of the 23d of May we encamped near its junction with the old legitimate trail of the Oregon emigrants. We had ridden long that afternoon, trying in vain to find wood and water, until at length we saw the sunset sky reflected from a pool encircled by bushes and a rock or two. The water lay in the bottom of a hollow, the smooth prairie gracefully rising in oceanlike swells on every side. We pitched our tents by it; not however before the keen eye of Henry Chatillon had discerned some unusual object upon the faintly-defined outline of the distant swell. But in the moist, hazy atmosphere of the evening, nothing could be clearly distinguished. As we lay around the fire after supper, a low and distant sound, strange enough amid the loneliness of the prairie, reached our ears—peals of laughter, and the faint voices of men and women. For eight days we had not encountered a human being, and this singular warning of their vicinity had an effect extremely wild and impressive.
