213 Brown County

Lake Shabine or Shawruno is the name of a lake near the head of Wolf river, from which there is a portage to the Oconto river of Green Bay.

Green Bay which derives its name from a fancied deeper green color of its waters than usual may be considered as a lake connected with Lake Michigan at the "Forte du Morts" or Death's Door. At this point there are several islands, the largest of which [is] called the Potawatomee Island, twenty eight miles in circumference & is about five miles in diameter. Rock Island (5 3/8 m. in circuit) lies near the north east corner of it, and Detroit and Plum islands lie between it and the main shore at the south. Detroit island is four miles long, [and] half a mile wide & 9 and 1 /4 miles around.

Chambers island is near the middle of Green Bay and may be considered as belonging to Michigan. It is four miles long & two broad and contains a lake or pond about a mile in length.

Sturgeon Bay and Little Sturgeon Bay are two small arms of Green Bay on the east side about half way between the town of Green Bay and Death's Door. At this point gypsum or plaster of Paris has been found, and probably exists in sufficient quantities to become important, and may hereafter be worked to advantage.
