"At the distance of a quarter of a mile back from the river, extends a terrace or elevated prairie, running north from the village, and forming a kind of semicircle around this bathingplace; and on this terrace, which is some twenty or thirty feet higher than the meadow between it and the river, are stationed every morning several sentinels, with their bows and arrows in hand, to guard and protect this sacred ground from the approach of boys or men from any directions."
