POETEB S SANDY LOAM. 



The surface soil of the Porter's sandy loam consists of a yellowish- 

 gray to gray, medium to coarse sandy loam varying in depth from 

 6 to 12 inches. In a few places a gray fine sandy loam is encountered 

 while in other spots where erosion has been active or where the rocks 

 are more thoroughly decomposed a reddish to brown sandy loam or 

 loam is found. The heavily forested areas are usually darker in color 

 and contain more organic matter than the soil in the cultivated fields. 

 In many places mica scales occur in the soil and here and there quartz 

 gravel and ro^k fragments are scattered over the surface. The Porter's 

 sandy loam is a mellow, friable soil, easily tilled and if properly 

 managed never bakes or clods. . 



The subsoil consists of a reddish or yellowish brown, heavy, sticky, 

 sandy loam which passes into a red or yellow clay loam or clay. In 

 many places it is a stiff, red clay, while in other places it is very 

 friable and the disintegrated rock comes near the surface.
