Note 31 — VOYAGES AND TRAVELS

For the history of Mackinac, see “Story of Mackinac,” in Thwaites’s How George Rogers Clark won the Northwest, and Other Essays in Western History (Chicago, 1903). By the “isthmus” the author means the Upper Peninsula of Michigan; the “point of land” must signify the island of Mackinac. The “mouth of the Illinois” is the outlet of Lake Michigan.—Ed.
