Note 245 — Chapter XXI

The boundaries are laid down on the great map of Franquelin, made in 1684, and preserved in the Dépôt des Cartes of the Marine. The line runs along the south shore of Lake Erie, and thence follows the heads of the streams flowing into Lake Michigan. It then turns northwest, and is lost in the vast unknown of the now British Territories. On the south, it is drawn by the heads of the streams flowing into the Gulf, as far west as Mobile, after which it follows the shore of the Gulf to a little south of the Rio Grande; then runs west, northwest, and finally north, along the range of the Rocky Mountains.
