imperceptibly into the Norfolk fine sandy loam, usually without any 

 appreciable change in level or of slope. It possesses better natural 

 drainage than any other soil in the area and consequently is highly 

 prized for truck crop production. Practically all of it is cleared and 

 used for cropping or for the location of dwellings and grounds. 



Norfolk fine sandy loam. — The surface soil of the Norfolk fine sandy 

 loam, to a depth of 9 inches, is a brown to grayish-brown loamy fine 

 sand. This is underlain to a depth of 18 to 20 inches by a yellow fine 

 sand, only slightly coherent. The deeper subsoil, from 20 inches to 36 

 inches or more, is a yellow to brownish-yellow, stiff sandy loam. 

 The surface of the type is level or but gently sloping, natural drain- 

 age conditions are good, and the land is highly esteemed for truck 

 crop production. Owing to its greater extent, not only in this area 

 but in the entire district, it is more important than the Sassafras 

 fine sandy loam for the production of truck crops. Both soils are 

 recognized as excelling any other in the district for this type of 

 farming. 



Keyport fine sandy loam. — The surface soil of the Keyport fine 

 sandy loam consists of about 8 inches of grayish-browm fine sandy 

 loam, somewhat coherent and tending to form crusts and clods. The 

 upper 14 inches of the subsoil is a mealy yellow loam to fine sandy 

 loam, and the deeper subsoil a heavy yellow loam, somewhat mottled 

 with gray below a depth of 24 inches. 



The surface of this soil is level and somewhat depressed below the 

 adjacent soils. Natural drainage is fairly good but has been supple- 

 mented in the Churchland area by extensive systems of tile under- 

 drainage. (PI. Ill, fig. 1.) 



The Keyport fine sandy loam is chiefly used for the growing of 

 truck crops and is almost completely under tillage for that purpose. 



Suffolk fine sandy loam. — The surface soil of the Suffolk fine sandy 

 loam, to a depth of about 9 inches, is a gray to brownish-gray fine 

 sandy loam. It is usually quite coherent and loamy. The subsoil, 

 from 9 to 18 inches, is a pale yellow or gray loam. The deeper sub- 

 soil to 36 inches or more is in most "places a gray fine sand, slightly 

 loamy and sometimes mottled with yellow iron stains. The material 

 in the lower part is frequently decidedly wet. 



The type occupies level to depressed areas in the upland and 

 occurs along some poorly marked streamways. It is poorly drained 

 in its natural condition, but has been generally underdrained and 

 rendered available for truck crop production in the Churchland area. 

 (PL III, fig. 2.) 



Norfolk fine sand. — The surface soil of the Norfolk fine sand, to a 

 depth of 8 inches, is a yellowish-brown or yellow fine sand, slightly 

 loamy. The subsoil, which extends to a depth of 36 inches or more, 

 without change, is a yellow fine sand.
