THE GRASSES OF MILWAUKEE COUNTY, WISCONSIN. 
BY CHARLES T. AND BEIRNE B. BRUES. 
Milwaukee County includes an area of about 180 square 
miles in the southeastern part of Wisconsin, and is adjacent to 
Lake Michigan along its entire eastern boundary. All of the 
county is covered by glacial drift and presents the moderately 
undulating surface characteristic of such drift deposits. Lake 
Michigan is about 580 feet above mean sea-level, and along the 
lake the shore rises in most places abruptly in the form of 
bluffs from 60 to 120 feet high. From these westward, the 
undulations assume a more or less parallel direction, defining 
slight ridges with a north and south trend, until in the western 
part of the county elevations of from 220 to 260 feet above the 
lake are attained. FTo large rivers traverse the county, although 
there are several streams of considerable size which empty their 
waters into the lake. The most important of these is the Mil¬ 
waukee river which enters the county on the north, and due 
to the position of the previously mentioned ridges, follows a 
southward course only from one to three miles removed from 
the lake shore, finally turning abruptly eastward near the cen¬ 
ter of the city of Milwaukee where it reaches Lake Michigan. 
The next in size, known as the Menomonee river, enters the 
county at the northwest corner and flows south and east 
through Wauwatosa into the Milwaukee river about three- 
fourths of a mile from its mouth. In the southern part of the 
city of Milwaukee is a third stream, the Kinnickinnic river, 
scarcely over five miles in length, which enters the lake with 
the Milwaukee river; and finally in the extreme southeastern 
part of the county, another small stream, Oak creek, flows into 
the lake. There are no lakes within the county, except two or
