ALTAVISTA LOAM. 



The Altavista Loam consists of a light gray to dark gray silty loam 

 to fine sandy loam, passing into a pale yellow silty to fine sandy loam at 

 about 8 inches. This pale, yellow stratum extends to about 12 to 14 

 inches. The typical subsoil is a heavy, friable to plastic, silty, fine 

 sandy clay of yelloAv color. Slight hummocks or low ridges are more 

 nearly a fine sandy loam underlain by a pale, red, fine to medium sandy 

 clay. In slight depressions the surface soil is dark gray to almost 

 black, heavy, silty or clay loam, with a clay subsoil showing mottlings 

 of red and drab. This is naturally a strong and productive soil. It is 

 used now for the growing of cotton, corn, and oats, and the yields are 

 satisfactory.

ALTAVISTA SILT LOAM. 



The surface soil of the Altavista Silt Loam consists of a gray to 

 yellowish-gray silt loam, to a depth of about 8 to 10 inches. The sub- 

 soil, to a depth of about 15 to 20 inches is a dull, yellow, or drab, silty 

 clay. Below 20 to 24 inches, the material shows a yellow or drab, stiff, 

 plastic clay, showing also considerable mottling of red. In places the 

 red mottlings give way to gray. The surface soil is smooth, and pos- 

 sesses a floury feel, and when once plowed and harrowed, a good tilth 

 is secured. Corn and oats give best returns, although cotton can be 

 grown on the higher and better drained areas.

CONGAREE SERIES. 



The Congaree Series represents the River Flood Plains and first 

 bottom lands lying along the streams in the Piedmont Plateau Region. 

 These soils usually lie only a few feet above the normal water-level of 

 the streams. The surface is prevailingly flat, with slight undulating
