cliiied in importance, she was able, on account of her good har- 

 bor a,nd fine location, to turn her attention to other lines of busi- 

 ness and to continue as pros]3erous as ever. 



The middle area in Dubuque County was neither an impor- 

 tant lead producing section nor a good farming region, so that 

 after its mines were exhausted it declined in importance. 



The non lead producing area was settled last, but it has 

 gi'own rapidly and steadily ever since settlement. The wealth 

 of the county centered at first in the lead area. In 1875 the 

 middle area had equalled the lead area, while the non lead pro- 

 ducing area had outstripped them both. In 1895 the third area 

 had a per capita valuation of $212.5, the middle area $184.7, 

 and the lead area $143.5. 



Along with this change in relative rank in population and 

 wealth, these three areas show certain parallel differences in 

 political affiliations. The third area has always been more 

 Republican, while the lead and middle areas had just as strongly 

 a Democratic tendency. Thus is shown the influence of eco- 

 nomic factors upon social and political life.
