NOTES AND QUERIES. 



CHARITON. 



In the map that accompanies the copy of Lewis and Clark that I have, Char- 

 iton is laid down as Charlatan, but in the text it is given as stated by Mr. Broad- 

 head. Perrin DuLac, who ascended the Missouri river in 1802, gives in his 

 "Voyage to Louisiane," published at Paris, 1805, an elaborate map of that river 

 and its branches, on which the Chariton is laid down as Grand and Little Charle- 

 ton. Brown's Western Gazetteer, pubUshed at Auburn, N. Y., 181 7, has the 

 name Charlatan. Breckenridge, in his " Views of Louisiana," published at Pitts- 

 burgh, Pa., 1 8 14, calls it Charlatan and Chareton. Breckenridge ascended the 

 Missouri in 181 1. J.

In the early part of the present century, there was a fort on the Missouri 

 river, between the Grand river and mouth of the Kansas, called Fort Osage, af-

In the year 1797, a Welshman named Evans and an American named Mac-

 the Americans. Is there any confirmation of this ? Otoe.
