by Louis XIV to Crozat. This grant empowered him " to carry on exclusively the trade in all our territories by us possessed and bounded by New Mexico, and by those of the English in Carolina; all the establishments, ports, harbours, rivers, and especially the port and harbour of Dauphin Island, formerly called Massacre Island ; the River St Louis, formerly called the Mississippi, from the sea-shore to the Illinois ; together with the River St Philip, formerly called the Missouri River, and the St Jerome, formerly called the "Wabash (the Ohio), with all the coun tries, territories, lakes inland, and the rivers emptying them selves directly or indirectly into that part of the river St Louis. All the said territories, countries, streams, and islands, we will to be and remain comprised under the name of ' The Government of Louisiana,' which shall be dependent on the general government of New France, and remain subordinate to it; and we will, moreover, that all the territories which we possess on this side of the Illinois be united, as far as need be, to the general government of New France, and form a part thereof, reserving to our selves to increase, if we think proper, the extent of the government of the said country of Louisiana." This document defined with tolerable precision the province of Louisiana.
