Local traditions here place the mouth of the Missouri River in 1803 at one
mile north of Maple Island; it is now four miles below the island. The mouth of
Wood River is one mile below Maple Island, and is supposed to have been in the
same place in 1803.—G. B. DORSEY, Gillespie, Ill.

This unfinished memorandum is found on the fly-leaf at beginning of the small
note-book designated by Elliott Coues—in his report upon the journals, made to the
American Philosophical Society, Jan. 20, 1893, and reprinted in our Appendix, post
—as "Codex A," from which book is here reproduced Clark's journal of the expedition
from May 13 to August 14, 1804. Occasional entries, written by Lewis during
that period, will be here designated by his name within brackets at the beginning of
such matter.

As stated in the Introduction to the present volume, there are two collections of
original journals of the explorers—that made by Thomas Jefferson and now in the
custody of the American Philosophical Society at Philadelphia; and that owned by
Mrs. Julia Clark Voorhis and Miss Eleanor Glasgow Voorhis, of New York—granddaughter
and great grand-daughter, respectively, of William Clark. In all references
to the Philadelphia codices, we shall for convenience give Coues's lettered designations
thereof (e.g., "Codex A"); the four Voorhis note-books will be designated by
their Arabic numerals (e. g., "Clark-Voorhis note-book, No.1"). Other Clark
manuscripts in the Voorhis collection will be specifically
alluded to, as they appear in our volumes.—Ed.

Lewis appears to have spent his time chiefly in St. Louis, where, on March 9
and, 10 he was principal witness to the formal transfer of Upper Louisiana. See act
of transfer, in Billon, Annals of St. Louis (St. Louis, 1886), pp. 360, 361,—Ed.
