Washington Mar. 22. 07.
It is with great pleasure that, at the request of Govenor Lewis, I send you the seeds now inclosed, being a part of the Botanical fruits of his journey across the continent: I cannot but hope that some of them will be found to add useful or agreeable varieties to what we now possess. these, with the descriptions of plants, which, not being in seed at the time, he could not bring, will add considerably to our Botanical possessions. he will equally add to the Natural history of our country. on the whole, the result confirms me in my first opinion that he was the fittest person in the world for such an expedition. he will be with you shortly at Philadelphia, where I have no doubt you will be so kind as to shew him those civilities which you so readily bestow on worth. I send a similar packet to mr McMahon, to take the chance of a double treatment. in confiding these public deposits to your & his hands, I am sure I make the best possible disposition of them. Accept my friendly salutations & assurances of great esteem & respect.
