centages of the native and foreign bom of these various towns 

 bear about the same relation to that of the entire county as they 

 did in 1850, except Pleasant Prairie and Wheatland. When 

 Southport was divided and the southern part added to Pleasant 

 Prairie, the evident predominance of the Sew York and IN'ew 

 England elements in this district, had the effect of raising the 

 percentage of the native bom in this town from 57^ in 1850 to 

 66.3^ in 1860, which is .7^ above the county average in 1860. 

 The town of Pandall, which was formed out of what was a part 

 of Wheatland in 1850, has a percentage of native bom of 78.9^, 

 or IZ.Zfo above that of the county, while the percentage of the 

 native born of what is left of Wheatland, after the division, 

 sinks to 54.9^, or 10.7;^ below the county average. This is a 

 strong indication that, while the town was not arbitrarily 

 divided in 1850, it was nevertheless naturally divided by the 

 settlement of the foreign elements in the northern part and the 

 native in the southern part. This fact may have been what led 

 to the division of Wheatland in 1860. In 1870 the percentage 

 of the native born in Pleasant Prairie again sinks below the 

 county average, while the percentage of the native and foreign 

 bom for the other towns maintain about the same relation to 

 the county average as they did in 1850 and 1860. 



The sub-joined maps in Plate XL. show very clearly the loca- 

 tion of the native and foreign elements in the county in 1850, 

 1860, and 1870, and verify the conclusion drawn from Table 

 1 in regard to the location of the foreign elements.
