The Louisiana mission of the Jesuits, while producing several martyrs, and rich in striking examples of missionary zeal, has yielded but meagre documentary results; few of the papers in the present series touch upon its work, and indeed detailed knowledge thereof is not easily obtainable. Severed from Canada by a long stretch of wilderness, communication with the St. Lawrence basin was difficult and spasmodic, and in the case of the Jesuits generally unnecessary; for, having their own superior at New Orleans, his allegiance was to the general of the order in France, not to his fellow-superiors in Quebec and Montreal. The several missions of New France played a large part in American history; that of Louisiana, although interesting, is of much less importance. THE RELATIONS. A few explorers like Champlain, Radisson, and Perrot have left valuable narratives behind them, which are of prime importance in the study of the beginnings of French settlement in America; but it is to the Jesuits that we owe the great body of our information concerning the frontiers of New France in the seventeenth century. It was their duty annually to transmit to their superior in Quebec, or Montreal, a written journal of their doings; it was also their duty to pay occasional visits to their superior, and to go into retreat at the central house of the Canadian mission. Annually, between 1632 and 1673, the superior made up a narrative, or _Relation_, of the most important events which had occurred in the several missionary districts under his charge, sometimes using the exact words of the missionaries, and sometimes with considerable editorial skill summarizing the individual journals in a general account, based in part upon the oral reports of visiting fathers. This annual _Relation_, which in bibliographies occasionally bears the name of the superior, and at other times of the missionary chiefly contributing to it, was forwarded to the provincial of the order in France, and, after careful scrutiny and re-editing, published by him in a series of duodecimo volumes, known collectively as _The Jesuit Relations_.
