The Jefferson Papers also contain, in Jefferson’s handwriting, the Cypher establ ^d. with Captain Lewis. key. Artichokes.

Meanwhile, on April 23, before he had received Lewis’s letter, Jefferson had written to him: “ I have not been able to hear any thing of you since Mar. 7. till two or three days ago. Lieut ^t. Wilson told me you would leave Frederic the 18 ^th. inst. & that you had been detained till then at Harper’s ferry, where Capt Murray also told me he had seen you. I have no doubt you have used every possible caution to get off, and therefore we have only to lament what cannot be helped, as the delay of a month more may lose a year in the end.--will you be so good as to call on Doct ^r. Bollman with my compliments & pay him for some wine sent me? I suppose it will be about 12. Doll. but it must be whatever he says. I will also thank you to purchase for me a Leopard or tyger’s skin, such as the covers of our saddles were cut out of. in North 3 ^d. street & North 4 ^th. street a few doors only from Market street there used to be a considerable furrier’s store in each. at one of these it was that I saw a robe of what they called the Peruvian sheep, and I took to be of the Lama or Vigogna. it was made up of several skins, & was of the price of 12.D. if ther [sic.-- Ed.] be such a thing there now, you can either observe & report it to me, or if you think it good (for I have almost forgot it) I would take it at once. let me hear from you on your reciept of this, and inform me of your prospect for getting off. I have letters here for you from your friends in Albemarle. Accept my affectionate salutations. ”

After receiving Lewis’s letter, Jefferson wrote, on April 27: “ Your’s of the 20 ^th. from Lancaster was recieved the night before last. not having heard from you since the time of my leaving Washington, I had written to you on the 23 ^d. and lodged it in Philadelphia.

" you will therefore probably recieve that & this together. I inclose you a copy of the rough draught of instructions I have prepared for you, that you may have time to consider them, & to propose any modifications which may occur to yourself as useful. your destination being known to m ( ^~ r) Patterson, Doct ^rs. Wistar, Rush & Barton, these instructions may be submitted to their perusal. a considerable portion of them being within the field of the Philosophical society, which once undertook the same mission, I think it my duty to consult some of it’s members, limiting the communication by the necessity of secrecy in a good degree. these gentlemen will suggest any additions they will think useful, as has been before asked of them.--we have recieved information that Connor cultivates in the first degree the patronage of the British government; to which he values ours as only secondary. as it is possible however that his passion for this expedition may overrule that for the British, and as I do not see that the British agents will necessarily be disposed to counterwork us, I think Connor’s qualifications make it desireable to engage him, and that the communication to him will be as useful, as it was certainly proper under our former impression of him. the idea that you are going to explore the Missisipi has been generally given out: it satisfies public curosity, [ sic -- Ed. ] and masks sufficiently the real destination. I shall be glad to hear from you, as soon after your arrival at Philadelphia as you can form an idea when you will leave, & when be here. accept assurances of my constant & sincere affection. ”

Three days later, on April 30, Jefferson sent further instructions to Lewis: “ I think we spoke together of your carrying some cast iron corn mills to give to the Indians or to trade with them, as well as for your own use. lest however I should be mistaken, I mention them now. I make no doubt you have consulted with m ( ^~ r) Ellicot as to the best instruments to carry. I would wish that nothing which passed between us here should prevent your following his advice, which is certainly the best. should a time-piece be requisite, it is probable m ( ^~ r) Garnet can furnish you one. neither Ellicot nor Garnet have given me their opinion on the substituting a meridian at land, instead of observations of time, for ascertaining longi- ”
