CABRINGTO.V S.^NDY LOAM. 



The surface soil of the Carrington sandy loam, to a depth of 10 

 inches, is a brown to dark-brown sandy loam. The subsoil is a 

 coarse yellowish-brown sandy loam, having a grayish cast and con- 

 taining considerable silty material. Many small pieces of rock, 

 coarse sand, and gravel are incorporated in both the surface soil 

 and subsoil. 



There is a considerable variation in texture over this type. The 

 more gentle slopes contain a higlier percentage of organic matter 

 and are of a more loamy character. Along the tops and sides of the 

 ridges and knoblike crests of the hills the surface covering is gener- 

 ally a sandy to fine sandy loam underlain by loose, calcareous, 

 gravelly material. Small rock fragments, assorted gravel, and oc- 

 casional bowlders are scattered over the surface and embedded in 

 the soil layer. 



The Carrington sandy loam is practically all found in the south- 

 eastern corner of the county, in Blaine and Vernon Townships, 

 where it occupies the conspicuous extended chain of hills in this 

 moraine section. A few smaller ridges and knolls covered with 

 this soil are scattered throughout the county, many of them too 

 small to justify separate mapping. Tavo miles northwest of Dows, 

 in section 26, Blaine Township, a prominent hill of glacial origin —
