LEWIS (1774-1809)  , See also:American explorer, was See also:born near See also:Charlottesville, See also:Virginia, on the 18th of See also:August 1774 . In 1794 he volunteered with the Virginia troops called out to suppress the " See also:Whisky Insurrection," was commissioned as See also:ensign in the See also:regular See also:United States See also:army in 1795, served with distinction under See also:General See also:Anthony See also:Wayne in the See also:campaigns against the See also:Indians, and attained the See also:rank of See also:captain in 1797 . From 18o1 to 1803 he was the private secretary of See also:President See also:Jefferson . On the 18th of See also:January 1803 Jefferson sent aconfidential See also:message to See also:Congress urging the development of See also:trade with the Indians of the See also:Missouri Valley and recommending that an exploring party be sent into this region, notwithstanding the fact that it was then held by See also:Spain and owned by See also:France . Congress appropriated funds for the expedition, and the president instructed See also:Lewis to proceed to the See also:head-See also:waters of the Missouri See also:river and thence across the mountains to the Pacific Ocean . With Jefferson's consent Lewis See also:chose .as a See also:companion Lieut . See also:William See also:Clark, an old friend and army comrade . The preparations were made under the orders of the See also:War See also:Department, and, until the See also:news arrived that France had sold See also:Louisiana to the United States, they were conducted in secrecy . Lewis spent some See also:time in See also:Philadelphia, gaining additional knowledge of the natural sciences and learning the use of See also:instruments for deter-See also:mining positions; and See also:late in 1803 he and Clark, with twenty-nine men from the army, went into See also:winter quarters near St See also:Louis, where the men were subjected to rigid training . On the 14th of May 1804 the party, with sixteen additional members, who, however, were to go only a See also:part of the way, started up the Missouri river in three boats, and by the 2nd of See also:November had made the difficult ascent of the stream as far as 470 21' N. See also:lat., near the site of the See also:present See also:Bismarck, See also:North Dakota, where, among the See also:Mandan Indians, they passed the second winter . See also:Early in See also:April r8os the ascent of the Missouri was continued as far as the three forks of the river, which were named the Jefferson, the See also:Gallatin and the See also:Madison . The Jefferson was then followed to its source in the See also:south-western part of what is now the See also:state of See also:Montana .

Procuring a See also:

guide and horses from the Shoshone Indians, the party pushed westward through the Rocky Mountains in See also:September, and on the 7th of See also:October embarked in canoes on a tributary of the See also:Columbia river, the mouth of which they reached on the 15th of November . They had travelled upwards of 4000 M. from their starting-point, had encountered various See also:Indian tribes never before seen by whites, had made valuable scientific collections and observations, and were the first explorers to reach the Pacific by See also:crossing the See also:continent north of See also:Mexico . After spending the winter on the Pacific See also:coast they started on the 23rd of See also:March 18o6 on their return See also:journey, and, after crossing the See also:divide, Lewis with one party explored Maria's river, and Clark with another the Yellowstone . On the 12th of August the two explorers reunited near the junction of the Yellowstone and the Missouri, and on the 23rd of September reached St Louis . In spite of exposure, hardship and peril only one member of the party died, and only one deserted . No later feat of exploration, perhaps, in any See also:quarter of the globe has exceeded this in romantic See also:interest . The expedition was commemorated by the Lewis and Clark Centennial Exposition at See also:Portland, See also:Oregon, in 1905 . The leaders and men of the exploring party were rewarded with liberal grants of See also:land from the public domain, Lewis receiving 1500 acres; and in March 1807 Lewis was made See also:governor of the See also:northern part of the territory obtained from France in 1803, which had been organized as the Louisiana Territory . He performed the duties of this See also:office with See also:great efficiency, but it is said that in the unwonted quiet of his new duties, his mind, always subject to See also:melancholy, became unbalanced, and that while on his way to See also:Washington he committed See also:suicide about 6o m. south-See also:west of See also:Nashville, See also:Tennessee, on the rlth of October 1809 . It is not definitely known, however, whether he actually committed suicide or was murdered .
