« IREDELL CLAY LOAM. 



The surface soil of this type consists of a dark gray, dark brown to 

 ahnost black heavy clay, containing a high percentage of small rounded 

 iron pebbles or concretions, and having a depth of 4 to 8 inches. The 

 subsoil is a yellowish-brown to greenish-brown, plastic, sticky, heavy 

 clay, which at about 24 inches passes into the partially decomposed 

 rock. It is the heaviest type in the series so far encountered. Where 

 the subsoil comes near the surface, cultivation is difficult. Owing to 

 the impervious character of both the soil and the subsoil, it is restricted 

 as to its crop adaptation. The soil is suited, however, to both wild and 

 cultivated grasses, which can be used advantageously for grazing of 

 sheep and cattle. Wheat, oats, and corn also, can be successfully grown 

 under proper treatment. 



ALAMANCE SERIES. 



The soils of the Alamance Series constitute a large part of the land 

 in Union, Stanly, Montgomery, and Randolph counties, and are well 

 developed in Cabarrus, Davidson, Anson, Moore, Rowan, Chatham, 

 Granville, and spots in a few other counties in that general region. 

 These soils have been derived from the "Carolina slate"i formation,
