Table I shows the moveinent of population in the state, in the 

 county and in the three groups of the county. 



It will be observed that from the year 1860 to 1890 there was 

 a steady, consistent rise in the population, both of the state, in- 

 cluding Cook County, and in the state outside of Cook County. 

 The state outside of Cook County, while it started at 28.1 per 

 square mile in 1860, rose to 47.2 in 1890. But Jo Daviess 

 County, while it started in 1860 wuth a population of 46.2, in- 

 stead of rising, fell to 42.4 in 1890.^ !N'ow let us examine the 

 movement of population in the three gToups. In Group I, out- 

 side of the city of Galena, the population started in 1860 at 

 44.1. This shows the densely populated condition of the lead 

 mining areas. After 1860, the miners and the younger portion 

 of the population left the country in swarms, and the result has 

 been a steady, rapid decline, till in 1890 the population had 

 reached 30.6 per square mile. From the table it will be noticed 

 that in the second and third groups, w^here agriculture was the 

 predominating industry, the region in 1860 was not so thickly 

 settled as in Group I ; yet they both enjoyed a continuous rise 

 in population till 1880, and although they declined from 1880 



1 The reason why the population per square mile of Jo Daviess County is high, is ou 

 account of the relatively large effect of Galena, where about 20 per cent, of the popula- 

 tion of the county live on one per cent, of its area.
