discharging separately from the main slough; and is traversed lengthwise by a sand-bank 6 m. long, which may be called Lesueur's Terrace. For this Prairie or Bald isl. is no doubt that formerly known as Isle Pelée, on which was built Fort Lesueur, 1695. The middle opening of Vermilion slough is in common with a lower outlet of Vermilion r. This is Rapid r. of Long, and Rivière Jaune of the French; "R. Jaune" appears on Franquelin's map, 1688. The upper discharge of this river is at Hastings, and thus above the mouth of the St. Croix; Lake Isabel is a small sheet between the river and the town. The Minnesota county line between Goodhue and Dakota strikes the Mississippi just 1¼ m. below the lower mouth of Vermilion r. At the mouth of the St. Croix the Mississippi ceases or rather begins to separate Wisconsin from Minnesota; so that henceforth Pike proceeds in the latter State. [I-71] Hastings to Newport, 18½ m. by the channel; camp a mile and a half beyond this, vicinity of present Red Rock, Washington Co., at the point on the small strip of prairie where the Sioux had their celebrated red medicine-stone; this was the "large painted stone" Pike observed. It gave name to Red Rock, having meanwhile become a historical object. We read in Long, I. p. 287: "a stone which is held in high veneration by the Indians on account of the red pigment with which it is bedawbed, it is generally called the painted stone.... It is a fragment of syenite, which is about four and a half feet in diameter.... The Indians frequently offer presents to the Great Spirit near this stone," etc. The party found near the stone an eagle's feather, roots of _Psoralea esculenta_, and willow sticks painted red; they secured a fragment of the idol for their mineralogical collection. At the time of this visit (1823) there was an Indian burying-ground a short distance above--in sight from the spot--if that place can be called a burying-ground where the bodies are not buried in the ground but scaffolded in the air; a mode of disposition of the dead which might be called hypsitaphy, in distinction from bathytaphy or ordinary underground interment. See Pike's remarks on Sioux burial on the 21st. To reach the sacred spot, hallowed by association with the deepest religious emotions of the untutored aboriginal mind, Pike left Hastings, where the river was bridged by the C., M. and St. P. R. R. in 1871 (Act of Minn. Legisl., Feb. 7th, 1867), and soon passed the site of Nininger, Dakota Co., a small town built at the lower point of a steep bluff which fronts the river's edge on the S., at the mouth of the rivulet which serves as the upper discharge of Lake Rebecca or King l.--in fact the whole bottom on his left is an island 2¾ m. long, extending from Hastings to Nininger, being cut off by the slough of which King l. is a dilation. On the right, in Washington Co., bluffs front the river for a mile or more, to the lower opening of Boulanger slough, which cuts off an island 2½ m. long.
