MOWER COUNTY. 351

than it is on the hillsides or slopes adjoining, and on high hills or steep 

 slopes it is thin or wanting, the wash of the surface having carried it into 

 the valleys. Along streams it often consists of an arenaceous loam vari- 

 ously mingled with the detritus of the flood-plain. 



The soil of the county is everywhere characterized by the strength and 

 fertility that the drift soils of the Northwest are noted for. They are the 

 most reliable soils, for all the purposes of the farmer, that are known. 

 The states that are regularly and deeply buried in drift deposits are known 

 as the best farming states of the union. Certain rock soils, endowed with 

 unusual special qualities, may excel in the production of certain crops, 

 especially in favorable seasons, but for general tillage they cannot compete 

 with the homogeneous drift soils, through which are disseminated the good 

 qualities of the various rocks concerned in their production, in the propor- 

 tions that make stability and diversity equally certain. 



In the examination of the county the native varieties of trees and 

 shrubs were noted, and the following list comprises the species that were 

 seen. In respect to the trees it is probably nearly complete for the county, 

 but there are doubtless other species of shrubs.
