Note 126 — Chapter IV

"The St. Clair (according to Dr. Bigsby) is the only river of discharge for Lakes Superior, Michigan, and Huron, which cover a surface of thirty-eight and a half million of acres, and are fed by numerous large rivers. Other able observers are of opinion that the Missouri and the Mississippi receive some of the waters of Superior and Michigan. Many persons think that a subterraneous communication exists between all the great lakes, as is surmised to be the case between the Mediterranean and the Euxine."—Montgomery Martin.
