Jacques Gravier, a French missionary in America, died in 1708. Soon after his arrival in Canada, in 1684, he was sent to the Illinois region, where he followed up the labors of Mar-quette and Allouez among the Kaskaskias and other bands of the Illinois, and became the real founder of the mission, which he directed for many years, meeting much opposition from the medicine men, and receiving at their hands a wound which ultimately caused his death. He compiled a grammar of the Illinois, which was highly esteemed and formed the basis of all subsequent works of the kind. When Iberville began the settlement of Louisiana, the Illinois prepared to go down the Mississippi; but the Kaskaskias, the first to move, were induced by Gravier to halt at the place which now bears their name. He went down to confer with Iberville, and has left a journal of his canoe voyage. He descended again in 1706, and went to Europe. He returned in February, 1708, but must have reembarked, as he died at sea in April. Of his writings the following have been printed: Relation de ce qui s'est passe dans la mission de l'Immaculee Conception au pays des Illinois 1693-'4 (8vo, New York, 1857); Relation ou Journal du voyage en 1700 depuis le pays des Illinois jusqu'a l'embouchure du Mississipi (1859); Lettre sur les affaires de la Iouisianc, fev. 23, 1708 (1865).
