Many of the Sioux are semi-civilized; some are "blanket-Indians," so called, but there are no longer any murderous or predatory bands, and all save a few stragglers are on the reservations. From 1812 to 1876, more than half a century, they were the scourge of the West and the Northwest, but another outbreak is highly improbable. They once occupied the vast region included between the Mississippi and the Rocky Mountains, and were always migratory in their methods of living. Over fifty years ago, when the whites first became acquainted with them, they were divided into nearly fifty bands of families, each with its separate chief, but all acknowledging a superior chief to whom they were subordinate. They were at that time the happiest and most wealthy tribe on the continent, regarded from an Indian standpoint; but then the great plains were stocked with buffalo and wild horses, and that fact alone warrants the assertion of contentment and riches. No finer-looking tribe existed; they could then muster more than ten thousand warriors, every one of whom would measure six feet, and all their movements were graceful and elastic. According to their legends, they came from the Pacific and encountered the Algonquins about the head waters of the Mississippi, where they were held in check, a portion of them, however, pushing on through their enemies and securing a foothold on the shores of Lake Michigan. This bold band was called by the Chippewas Winnebagook (men-from-the-salt-water). In their original habitat on the great northern plains was located the celebrated "red pipe-stone quarry," a relatively limited area, owned by all tribes, but occupied permanently by none; a purely neutral ground--so designated by the Great Spirit--where no war could possibly occur, and where mortal enemies might meet to procure the material for their pipes, but the hatchet was invariably buried during that time on the consecrated spot. The quarry has long since passed out of the control and jurisdiction of the Indians and is not included in any of their reservations, though near the Sisseton agency. It is located on the summit of the high divide between the Missouri and St. Peter's rivers in Minnesota, at a point not far from where the ninety-seventh meridian of longitude (from Greenwich) intersects the forty-fifth parallel of latitude. The divide was named by the French Coteau des Prairies, and the quarry is near its southern extremity. Not a tree or bush could be seen from the majestic mound when I last was there, some twenty years ago--nothing but the apparently interminable plains, until they were lost in the deep blue of the horizon.
