Cotton, corn, oats and wheat are the principal crops. Liming, incor- 

 poration of organic matter, and deeper and better preparation are 

 essential for the improvement of the Penn silt loam. 



AVERAGE MECHANICAL ANALYSIS. 



HEKNDON SERIES. 



The soils of the Herndon Series occupy high, isolated hills or ridges 

 in the Piedmont region, and are derived principally from quartzite 

 and quartzite schists. Many of the low mountains and monadocks will 

 be occupied by the Herndon soils. The Herndon stone loam mapped in 

 Caswell County, is the only member of the series thus for encountered. 



HERNDON STONY LOAM. 



The Herndon Stony Loam to a depth of about 6 inches is a yellowish- 

 gray or gray fine, sandy loam, containing about 30 to 60 per cent of rock 

 fragments of quartzite schists, and fine gravel. The subsoil is yellow, 

 fine, sandy clay, whicli passes into a red clay at about 12 to 15 inches. 

 Stone interferes with cultivation of this soil, and it is best suited to 

 forestry and pasturage. 



ROUGH GULLIED LAND. 



(This was mapped Caswell sandy loam in Caswell County.) In 

 "eality, the Caswell sandy loam should have been divided into Appling 

 sandy loam and Rough Gullied Land. The greater part of it or rather 

 that part of it occupying the more gently rolling to rolling areas, should 

 be Appling sandy loam; while the rough, broken, eroded hillsides, 

 should be included as Rough Gullied Land. The surface soil is a light 

 gray, yellowish-gray or ashy-colored medium sandy loam to a depth of
