On the 24th of April 1820, he arrived at St. Louis, on his way from Philadelphia to Council Bluff, to rejoin the party. He was accompanied by Captain John R. Bell, attached to the exploring Expedition by order from the War Department, and by Dr. E. James, who had been appointed to serve as botanist and geologist, in consequence of recommendations from the Honourable Secretary of the Navy, from Dr. Torrey and Captain Le Conte.[49] [49] John R. Bell was a New Yorker, who was graduated from West Point in 1812, and served in the light artillery through the War of 1812-15. For a short time prior to his departure for the Missouri, he was commandant of cadets and instructor in infantry tactics at West Point. Afterwards he was in garrison at Savannah and Fort Moultrie; breveted major in 1824, he died the succeeding year. For sketch of Edwin James, the compiler of this account of the expedition, see preface of volume xiv. The secretary of the navy at this time was Smith Thompson, of New York (1768-1843). He succeeded George Crowinshield, of Massachusetts, in this office (1818), and held the post until 1823. Previous to his appointment he had been on the supreme bench of New York (since 1802), and had become chief justice (1814). In 1823 he was made associate justice on the federal bench. John Torrey (1796-1873), one of America's greatest botanists, was the son of a New York Revolutionary officer. Entering the army as a surgeon in 1824, he taught the sciences at West Point until 1828; from that time until 1855 he was connected, as professor of chemistry and botany, with Princeton College, the University of the City of New York, and the College of Physicians and Surgeons in New York City. He was one of the founders (1817) of the New York Lyceum of Natural History, which became the New York Academy of Sciences, and was the preceptor and lifelong associate of Asa Gray, with whom he also collaborated. Of especial interest to readers of the present volumes is the fact that Dr. Torrey undertook the examination of the botanical collections made on Long's expedition. He also examined the collections made by several later exploring parties, notably those of Frémont to the Rocky Mountains (1845) and California (1853). John Eatton Le Conte (1784-1860) was descended from a Huguenot family which settled at New Rochelle, New York, about the close of the seventeenth century. He served in the corps of topographical engineers from 1818 to 1831, gaining the brevet rank of major. Known as the author of special botanical and zoological studies, he was also a member of the New York Lyceum of Natural History, and vice-president of the Philadelphia Academy of Natural Sciences.—ED. Having procured horses, and equipped ourselves for a journey in the wilderness, we left St. Louis on the 4th of May, intending to proceed by the most direct route across the country to Council Bluff.
