Eighteen years after Groseilliers and Radisson’s first trip, Joliet and Marquette navigated the Mississippi for a long distance southward from the Wisconsin river, to the Arkansas; and again, after seven years more, in 1680, it was navigated between the Illinois and Rum rivers by Hennepin, and also, above the Wisconsin, by Du Luth. In 1682 La Salle led an expedition from the Illinois to the mouth of the Mississippi, and there proclaimed its vast drainage area to be the property of France. A few years later, about 1685–90, Le Sueur and his relative by marriage, Charleville, canoed from Lake Pepin far upward beyond the Falls of St. Anthony, probably to Sandy Lake; and in the last year of the seventeenth century, just forty-five years after Groseilliers superintended corn-raising by the Hurons on Prairie Island, Le Sueur and a large mining party navigated the whole extent of the Mississippi from near its mouth to the Minnesota river, and then advanced up that stream to the Blue Earth river. Without seeking or suggestion by himself, the name of Amerigo Vespucci (also commonly known, in Latin, as Americus Vespucius) was bestowed upon the New World, of which, next after Columbus, he was the most notable discoverer in the sense of bringing to the knowledge of Europe what he saw in four voyages. Though not in command of these expeditions, Vespucci was a skilled geographer, and his services as astronomer and pilot were required to determine and chart their courses, with the newly discovered lands. His letters of description, written to friends without expectation of publication, were printed and proved to be of such popular interest that they passed through many editions and translations, leading to the adoption of the name America, after his death, on maps and globes. It was at first applied to Brazil, which Vespucci coasted on his second, third, and fourth voyages, and was later extended to both North and South America. In his first voyage, with four vessels, leaving Spain May 10, 1497, and returning October 15, 1498, he appears to have sailed along the shores of Honduras, Yucatan, the Gulf of Mexico, Florida, and our southeastern seaboard north to Pamlico Sound.
