a large arm or bay on the west side of Lake Michigan, forming a part of the boundary between Wisconsin and the upper peninsula of Michigan. It is above 100 miles long, and from 15 to 35 broad. The epithet "Green" has been applied to it on account of the colour of the water, which is said to exceed 500 feet in depth. At the head of the bay, on the right bank of the Neenah, or Fox River, is a thriving town of the same name. The bay and river afford a perfectly secure harbour, and the largest steamers of Lake Michigan stop here, making it the principal place of deposit and transit for the imports and exports of Northern Wisconsin. Pop. (1853) about 2500.
