Clark signs on

From the Falls of the Ohio, William Clark pens a letter accepting Meriwether Lewis’s invitation to join the “enterprise” to explore the Missouri River to its source and from there to the Pacific Ocean. In Philadelphia, one of Lewis’s mentors, Caspar Wistar, seeks information about the Missouri River.

Clark Accepts

Clarksville July 18th 1803

Dear Lewis

. . . . .

I will cheerfully join you in an “official Charrector”[1]Earlier drafts read “I will cheerfully join in an ‘official Charrector’ on equal footing &c.” (emphasis added). See Clark’s Military Rank. as mentioned in your letter, and partake in the dangers, difficulties, and fatigues, and I anticipate the honors & rewards of the result of such an enterprise, should be successful in accomplishing it

This is an undertaking fraited with many difeculties, but My friend I do assure you that no lives with whome I would perfur to undertake Such a Trip &c. as your self, and I shall arrange my matters as well as I can against your arrival here.

With every sincerity & friendship Yr. Obt. Sevt.

What Direction the Missouri?

Philada. July 18, 1803.

Dear Sir

I beg leave to trouble you with the inclosed for Captain Lewis, they do not include many points, because his instructions have really anticipated every thing which occurred to me, & of course admitted of no additions but in detail.

. . . . .

What is the real direction of the Missouri? ’till the publication of McKenzie’s book I believed it to be nearly west, & if I am not mistaken M. Pirroux spoke of it in the same way for 2000 miles of its extent—but McKenzies account is Confirmed by the Gentleman who gave the account of the Wild Sheep, in his narrative he mentions the Missouri as existing no great distance from the Saskatchevine river. I shall write this day to Mr Peter Pond (who is mentioned by McKenzie) on the subject, he lives in Connecticut & I believe will give any information in his power without any particular explanation respecting the reason for asking it.[3]With this phrase, Wistar refers to Jefferson’s request to publicly state that the Western Expedition would go up the Mississippi, not the Missouri. See Jefferson’s Secrecy

With the greatest respect I am your affectionate friend
