The three counties which, in 1850, showed a majority of foreign born inhabitants were Manitowoc, Milwaukee, and Washington (the last named including the present Ozaukee County); and in each case Germans constituted more than half of that majority. Together those three counties had over 20,000, which was considerably more than one-half of all the Germans (38,054) domiciled in Wisconsin at that time. The other lake shore counties, together with Calumet, Fond du Lac, Dodge, Jefferson, and Waukesha, accounted for 15,000 of the balance, leaving about 3000 scattered over the rest of the state. Thus the area embraced by Lake Michigan, Lake Winnebago and lower Fox River, the upper reaches of Rock River, and the south boundary of Jefferson, Waukesha, and Milwaukee counties was all strongly and in the main distinctively German. Investigating the causes which may have operated to concentrate the German population within such clearly defined geographic limits, our first inquiry concerns the land on which settlement was taking place. And here we find that the distinguishing fact marking off the region in which Germans abounded from most of the other settled or partially settled areas of the state was its originally thickly wooded character. In a way almost startling, and superficially conclusive, the German settlements coincided with the great maple forest of southeastern Wisconsin, spreading also through the included pine forest on Lake Michigan south of Green Bay. Returning now to the Yankee element, we find that although it was strong in all of the settled districts save the five counties named, it was more completely dominant in some districts than in others. For example, in Walworth County the northeastern states furnished 96.5 per cent of the American population, while 3.5 per cent was furnished by sixteen other states. The foreign born constituted less than 16 per cent of the total.[2] Walworth County was a section of the new “Yankee Land,” which included in its boundaries also the counties of Racine and Kenosha, Rock, and at that time parts of Waukesha and Jefferson. Nowhere in that region were foreigners very numerous, and in many localities non-English speaking foreigners were almost scarce. Physically, this new Yankee Land comprised those portions of the prairies and openings of southern Wisconsin which lay not more than from sixty to seventy-five miles from the lake ports at Milwaukee, Racine, and Kenosha. The region was just as characteristically “open country” as that occupied so extensively by Germans was forested. One land type, the glacial marsh or swale--good for hay and pasture--was common to the two districts of country. But for the rest, the Yankee’s land was all ready for the plow if it was prairie, and if oak openings the labor of felling the scattered trees and dragging them away before the breaking team was comparatively light.
