[I-29] _Not_ the Saline r. of Pike's map, which was passed on the 3d. "Saline river" of the present text is a slip of the pen or memory; Pike meant to say Great Gravel r., as correctly laid down by this name on his map on the left or south, being lettered "G. Gravel R." This is not the Great Gravel or Big Gravois cr. of present maps, but the considerable stream now known as Grand Auglaise cr.--a name also perverted from the F. word _glaise_, clay, into Glaize or Wet Glaize cr. It heads in Laclede and Pulaski cos., in close relation with sources of the Gasconade, and runs about N. N. W. through Camden Co. to fall into the Osage from the S., on the right bank of the river, on Pike's left, at or near a place called Blackman's Mills. The Osage is here turning from its E. course to N., whence it soon bends W., then loops N. and again E., where it receives present Big or Pike's Little Gravel r., and completes another ox-bow bend. Camp of the 7th, opposite the notable bluff called "La Belle Roche," is marked on Pike's map, not far above a place now called Damsel, on the other side of the Osage; whence the Yungar is reached for breakfast on the 8th. [I-30] _Sic_, usually in Pike, and I make no change. But "Cheveux Blanche" is a phrase joining a masculine plural noun to a feminine singular adjective. The English ed. alters to Cheveu Blanc; but as doubtless the savage had more than one hair of that color, probably Cheveux Blancs would be better in form and fact for the F. name of the person also known as White Hair. [I-31] Before the Youngar is reached Pike passes on his left Linn cr.; county seat called Linn Creek, a mile above its mouth. The name of the river has fluctuated widely. Pike has Yungar, Youngar, and also Nehemgar; the latest G. L. O. and U. S. G. S. maps letter Niangua. The word, whatever may be its preferable form, is the Osage name of the bear, though by some it is said to refer to the numerous springs at the sources of the stream. It is by far the largest tributary of the Osage thus far reached; Pike credits it with a canoe navigation of 100 m. The main stream heads in Webster Co., in relation with sources of the Osage fork of the Gasconade, and runs through Dallas Co., also touching the W. border of Laclede, into Camden; its tributaries are numerous and widespread. One called Little Niangua falls in on the W., 6 or 8 m. above the mouth of the main river. To-day's voyage takes the Expedition past Purvis, and finishes about 4 m. above Bolinger or Bollinger cr., from the S., on which are the Osage Iron Works.
