Of these by far the most important are the township of Wauwatosa (pop., 1905, state census, 11,132), and the city of the same name, separated from the township in 1897 and having in 1905 a population of 2913; the city and township are on the Menominee river, immediately adjoining the city on the west.
In the Menominee river valley the peculiar cream-coloured Milwaukee bricks are made.
Milwaukee was on the direct route of travel between Fort Dearborn (Chicago) and the flourishing settlement at Green Bay, and at once after the treaties between the United States and the Menominee in 1831 and 1833 for the extinguishing of the Indian titles, settlers began to come to the neighbourhood.
Of these districts the Lake Superior regionwhich embraces the Marquette range (opened in 1854), the Menominee (1872), the Gogebic (1884), the Vermilion (1884) and the Mesabi (1892)first attracted exploration about 1844, when the copper deposits of the same region were opened, and produced from 1854 to 1908 a total of 1/210,239,551 long tons, of which 341,036,883 were mined in the period 1889-1908.
To the south of this is the Menominee iron district, marked somewhat regularly by east and west ridges.
