The expedition leaves Fort Massac, sets up a camp about three miles down the Ohio, and Lewis is “siezed with a violent ague” similar to malaria. In Vincennes, Indiana Territorial Governor William Henry Harrison pens a letter to William Clark providing maps and introducing John Hay of Cahokia.

Governor Harrison’s Assistance

Vincennes 13th Nov. 1803

My Dear Sir [William Clark]

The map mentioned in your letter of the 5th Instant had been taken from me by Mr. Jones who claimed it as the property of Mr. Hay of Cahokia, but as it was still in the possession of Mr. Jones I have had it copied & now send it to you by the Post rider . . . .

Your offer to let me hear from you occasionally I accept with a great deal of pleasure—& I beg of you to let me Know from Cahokia whether I can do any thing for you in yr. absence.

. . . . .

William H. Harrison1
