there proceeded up the Cumberland River by boat, as far as Clarksville; he then visited Nashville, Knoxville, Louisville, and Morganton, finally arriving at Charleston again in April, 179G. During all of this time he collected eagerly, and more or less extensively. His journals, however, give no indications of the species or the number of them found at Cahokia. He seems to have found a considerable number at Kaskaskia, at which place he spent most of his time while in Illinois. In his "Flora" we find mentioned about 100 species as occurring in the Illinois territory; this, however, at that time included all of the territory north of the Ohio which was visited by Michaux. This seems to have been his last extensive trip in America; and in August, 1796, he embarked for Amsterdam and was shipwrecked on the coast of Holland. He is said to have been nearly drowned himself, and a large part of his collections were lost. He remained in France for several years, studying his collections and preparing the manuscript for his "Flora." In 1800 he joined an expedition to Australia, but, becoming disgusted with the management, he landed on the Island of Mauritius, but from there he soon went to Madagascar; here he established a botanical garden and began collecting extensively; but he soon fell victim to the unhealthy climate, and died on November 13, 1802.
Michaux probably traveled more extensively in North America than any other early botanist. He was the author of numberless new species and many new genera of American plants. Unfortunately, the genus, Michauxia, which commemorates his name, is one discovered by himself in Persia; so that his name is not thus associated with North American botany, which was so greatly advanced by his studies and explorations.
Immediately following the exposition held at St. Louis in commemoration of the purchase of Louisiana from France, there was held another exposition upon the Pacific coast to celebrate the centennial of the arrival of the Lewis and Clark expedition at the mouth of the Columbia River. This expedition was the first to penetrate overland to the Pacific coast and the results of its successful termination were of immense importance to the entire northwestern country. The journals of the expedition contain many references to plants seen, and especially to those which were peculiar or interesting, or which were used by the Indians.
In the previously mentioned attempt at the exploration of the northwest country, Michaux was to accompany the party. In the expedition which finally did make the journey there was no person who could be called a botanist. Although Captain Lewis was a very keen and observant man, he could not overcome his lack of botanical training, and the results in this regard were hardly what they would have been had Michaux been with the expedition. The journey up the Missouri River was made in boats manned with oars and, owing to the rapid current of
