INDUSTRY OF OZAUKEE COUNTY. 
BY JULIUS TOMLINSON, OF PORT WASHINGTON. 
The land in this county is all timber land, yet the growth is 
not large when compared with the finest growth of western 
N. Y. It consists of white and red oak, maple, hickory, beech, 
white ash, basswood, ironwood, &c., upon the uplands, and 
black ash, elms, tamarac and cedar upon the lowlands. Some 
bitternut, slippery elm, wild plum and grape are also found in 
many localities. 
Wild raspberries, blackberries, strawberries, and in some 
places cranberries, are very abundant. 
The surface of the soil is rolling, more level in the eastern 
part along the lake, and quite hilly in the western part. 
The soil is clay, mixed with lime gravel, although the pro¬ 
portion in which each component is found varies considerably. 
In the eastern part the clay greatly predominates, and in the 
western part the gravel. There are localities, however, which 
are more sandy; yet I think on the whole that clay and gravel 
are the chief constituents of the soil. In the immediate valley 
of the Milwaukee river the soil is a light loam, with a gravel 
subsoil. As near as I can judge, about one-eighth of the 
county is low and swampy, but there are few of our lowlands 
that cannot be drained and made productive. 
A ledge of limestone runs through the county from north¬ 
east to south-west. It is seen on the shore of the lake about 
three and a half miles north of Port Washington, and crops 
out in two places in the same town where it is crossed by 
Sauk creek, and also where the Milwaukee river crosses it at 
Grafton, and where it is crossed by Cedar creek at Cedarburg.
