Lewis, one of his father's uncles was a member of the king's council, before the revolution. Another of them, Fielding Lewis, married a sister of general Washington. His father, William Lewis, was the youngest of five sons of colonel Robert Lewis, of Albemarle, the fourth of whom, Charles, was one of the early patriots who stepped forward in the commencement of the revolution and commanded one of the regiments first raised in Virginia, and placed on continental establishment. Happily situated at home, with a wife and young family, and a fortune placing him at ease, he left all to aid in the liberation of his country from foreign usurpations, then first unmasking their ultimate end and aim. His good sense, integrity, bravery, enterprise, and remarkable bodily powers, marked him as an officer of great promise; but he unfortunately died early in the revolution. Nicholas Lewis, the second of his father's brothers, commanded a regiment of militia in the successful expedition of 1776, against the Cherokee Indians; who, seduced by the agents of the British government to take up the hatchet against us, had committed great havoc on our southern frontier, by murdering and scalping helpless women and children, according to their cruel and cowardly principles of warfare. The chastisement they then received closed the history of their wars, and prepared them for receiving the elements of civilization, which, zealously inculcated by the present government of the United States, have rendered them an industrious, peaceable, and happy people. This member of the family of Lewises, whose bravery was so usefully proved on this occasion, was endeared to all who knew him by his inflexible probity, courteous disposition, benevolent heart, and engaging modesty and manners. He was the umpire of all the private differences of his county—selected always by both parties. He was also the guardian of Meriwether Lewis, of whom we are now to speak, and who had lost his father at an early age. He continued some years under the fostering care of a tender mother, of the respectable family of Meriwethers, of the same county; and was remarkable even in infancy for enterprise, boldness, and discretion. When only eight years of age he habitually went out, in the dead of night, alone with his dogs, into the forest to hunt the raccoon and opossum, which, seeking their food in the night, can then only be taken. In this exercise, no season or circumstance could obstruct his purpose—plunging through the winter's snows and frozen streams in pursuit of his object. At thirteen he was put to the Latin school, and continued at that until eighteen, when he returned to his mother, and entered on the cares of his farm; having, as well as a younger brother, been left by his father with a competency for all the correct and comfortable purposes of temperate life. His talent for observation, which had led him to an accurate knowledge of the plants and animals of his own country, would have distinguished him as a farmer; but at the age of twenty, yielding to the ardour of youth, and a passion for more dazzling pursuits, he engaged as a volunteer in the body of militia which were called out by general Washington, on occasion of the discontents produced by the excise taxes in the western parts of the United States; and from that situation he was removed to the regular service as a lieutenant in the line. At twenty-three he was promoted to a captaincy; and, always attracting the first attention where punctuality and fidelity were requisite, he was appointed paymaster to his regiment. About this time a circumstance occurred which, leading to the transaction which is the subject of this book, will justify a recurrence to its original idea. While I resided in Paris, John Ledyard, of Connecticut, arrived there, well known in the United States for energy of body and mind. He had accompanied captain Cook on his voyage to the Pacific ocean; and distinguished himself on that voyage by his intrepidity. Being of a roaming disposition, he was now panting for some new enterprise. His immediate object at Paris was to engage a mercantile company in the fur-trade of the western coast of America, in which, however, he failed. I then proposed to him to go by land to Kamschatka, cross in some of the Russian vessels to Nootka Sound, fall down into the latitude of the Missouri, and penetrate to, and through, that to the United States. He eagerly seized the idea, and only asked to be assured of the permission of the Russian government. I interested, in obtaining that, M. de Simoulin, minister plenipotentiary of the empress at Paris, but more especially the baron de Grimm, minister plenipotentiary of Saxe-Gotha, her more special agent and correspondent there in matters not immediately diplomatic. Her permission was obtained, and an assurance of protection while the course of the voyage should be through her territories. Ledyard set out from Paris, and arrived at St. Petersburgh after the empress had left that place to pass the winter, I think, at Moscow. His finances not permitting him to make unnecessary stay at St. Petersburgh, he left it with a passport from one of the ministers; and at two hundred miles from Kamschatka, was obliged to take up his winter quarters. He was preparing, in the spring, to resume his journey, when he was arrested by an officer of the empress, who by this time had changed her mind, and forbidden his proceeding. He was put into a close carriage, and conveyed day and night, without ever stopping, till they reached Poland; where he was set down and left to himself. The fatigue of this journey broke down his constitution; and when he returned to Paris his bodily strength was much impaired. His mind, however, remained firm, and he after this undertook the journey to Egypt. I received a letter from him, full of sanguine hopes, dated at Cairo, the fifteenth of November, 1788, the day before he was to set out for the head of the Nile; on which day, however, he ended his career and life: and thus failed the first attempt to explore the western part of our northern continent.

In 1792, I proposed to the American Philosophical Society that we should set on foot a subscription to engage some competent person to explore that region in the opposite direction; that is, by ascending the Missouri, crossing the Stony mountains, and descending the nearest river to the Pacific. Captain Lewis being then stationed at Charlottesville, on the recruiting service, warmly solicited me to obtain for him the execution of that object. I told him it was proposed that the person engaged should be attended by a single companion only, to avoid exciting alarm among the Indians. This did not deter him; but Mr. Andre Michaux, a professed botanist, author of the Flora Boreali-Americana, and of the Histoire des Chesnes d'Amerique, offering his services, they were accepted. He received his instructions, and when he had reached Kentucky in the prosecution of his journey, he was overtaken by an order from the minister of France, then at Philadelphia, to relinquish the expedition, and to pursue elsewhere the botanical inquiries on which he was employed by that government: and thus failed the second attempt for exploring that region.

In 1803, the act for establishing trading houses with the Indian tribes being about to expire, some modifications of it were recommended to congress by a confidential message of January 18th, and an extension of its views to the Indians on the Missouri. In order to prepare the way, the message proposed the sending an exploring party to trace the Missouri to its source, to cross the Highlands, and follow the best water-communication which offered itself from thence to the Pacific ocean. Congress approved the proposition, and voted a sum of money for carrying it into execution. Captain Lewis, who had then been near two years with me as private secretary,
