Jefferson showed his versatility in the instructions to Captain Lewis, which are a model of fulness and clearness. The route to be followed, natural products and possibilities--animal, vegetable, and mineral--climatic conditions, commercial routes, the soil and face of the country, were all dwelt on. The character, customs, disposition, territory occupied, tribal relations, means of subsistence, language, clothing, disease, moral attributes, laws, traditions, religion, intellectuality, extent and means of trade, war methods, with respect to the Indian tribes visited, were to be studied and reported. The topography of the country was to be accurately determined, astronomically and otherwise, and the maps and notes multiplied to avoid total loss. The good-will of the chiefs was to be sought, peaceful methods pursued, and the inflexible opposition of any extensive force promising bloodshed was to be met by withdrawal and retreat. The country then being outside the limits of the United States, passports from the ministers of Great Britain, Spain, and France were furnished. Meriwether Lewis was born August 17, 1774, near Charlottesville, Va., being the son of John Lewis and Miss Meriwether, and grand-nephew of Fielding Lewis, who married a sister of George Washington. Volunteering, at the age of twenty, in the militia called out by Washington to put down the Shay rising, he was made ensign of the Second Sub-Legion May 1, 1795, and appointed in First Infantry November, 1796, where he rose to be paymaster and captain in 1800. He was a considerate and efficient officer, an expert hunter, versed in natural history, familiar with Indian character and customs. Appreciating his deficiencies in certain branches of science important in this expeditionary duty, he at once sought instruction from competent professors. Jefferson describes Lewis as follows: "Of courage undaunted, possessing a firmness and perseverance of purpose which nothing but impossibilities could divert from its direction, ... honest, disinterested, liberal, of sound understanding and a fidelity to truth so scrupulous that whatever he should report would be as certain as seen ourselves." The management and success of the expedition, it may here be said, fully justified the selection by and encomiums of Jefferson.
