Quality Glass II. This class embraces the stands of medium growth 

 on the great body of the upland soils of eastern N'orth Carolina. The 

 soils of this quality class include the greater portion of the flat woods 

 (consisting of the more level tracts of Norfolk fine sands; loams, and 

 silts, as designated by the Bureau of Soils) tbe Selma silt and Selma 

 loam, with the water table usually about 20 feet below the surface, 

 foi'merly largely occupied by the longleaf pine; compact clays occupied 

 by hardwood swamps; the rolling loams and clay loams of the Norfolk 

 series, largely north of the Eoanoke River and in Chowan, Gates, and 

 JSTortbampton counties, formerly partly occupied by shortleaf pine. 

 The usual depth of the water table in these soils is from 20 to 25 feet 

 below the surface. It is lowest for this quality in the fine grained sands 

 and loams. 



Quality Class III. This includes loblolly pine stands of very slow 

 growth. The soils characteristic of these are the better drained parts 

 of the flat woods, particularly the areas with compact clay soils (char- 

 acterized by roundleaf blackjack oak and post oak) ; the rolling piney 

 lands and the Piedmont uplands; the savannas, edges of pocosons, sand 

 hills, and swamps subject to prolonged overflow, or difficult to drain. 

 The upland soils as a rule have the water table during the growing 

 season from 20 to 45 feet below the surface. The soils of some of the 

 poorly drained areas (very level clays, silts and peats are frequently satu- 

 rated for long periods during the growing season, alternating in the 

 case of clays with periods of semi-drought on account of the large
