The great work of discovery was reserved for Robert Cavelier de la Salle, a Frenchman. By his commands, Father Louis Hennepin made the discovery of the Upper Mississippi, as far as the Falls of St. Anthony. In January, 1682, La Salle himself, with twenty-three Frenchmen and eighteen Indians, set out for the exploration of the Lower Mississippi, entering the river from the Illinois, and descending it until he arrived at the Passes of the Delta. Here, to his surprise, he found the river divided into three channels. A party was sent by each, La Salle taking the western, and on April 9th the open sea was reached. The usual ceremonies attendant upon any great discovery were repeated here. Enlivened by success, the party returned to Quebec. La Salle returned to France, and in 1684, aided by his Government, set sail with four vessels, for the discovery of the river from the sea. In this he was unsuccessful. After encountering several storms and losing one of his vessels, the expedition entered St. Louis Bay (St. Bernard) on the coast of Texas. The party disembarked, one of the vessels returned to France, and the others were lost on the coast. Thus cut off, La Salle made every effort to discover the river by land; but in every attempt he failed. At length he was assassinated by one of his followers on the 19th of March, 1687. Thus terminated the career of the explorer of the Mississippi. The discovery of the mouth of the river from the sea, was an event of some years later, and was consummated by Iberville, in 1699. This person spent some time in navigating the river and the waters adjacent to its mouth. His brother, Bienville, succeeded him in these enterprises. A few years later, and we find settlements springing up upon the banks of the river. Since that time it has attracted a numerous population, and to-day, though desolated in parts by the contentions of armies, there is certainty in the belief that at some time these people of the great river will wield a mighty power in the political and commercial destiny of the American continent.
