“ The shores of Lake Michigan are generally low and sandy, and the land slopes gradually to the water. The northern shore of the lake is irregular and more rugged and picturesque than the other shores, the summit of the highest peak being about 1400 ft. above the sea. On the eastern side are numerous sand hills, formed by the wind into innumerable fantastic shapes, sometimes covered with stunted trees and scanty vegetation, but usually bare and rising to heights of from 150 to 250 ft. ”
