monly good to rather excessive. Seepage waters rise nearly to the 

 surface a.t the foot of slopes, rendering the lower lying portions of 

 the type somewhat more moist than the general average. The 

 natural tendency of the type to excessive drainage has been cor- 

 rected in the Swedesboro area through the incorporation of large 

 quantities of stable manure and of green crops plowed into the 

 surface soil. 



The type is practically all cleared and used for intensive forms 

 of crop production. 



Sassafras sandy loam. — The surface soil of the Sassafras sandy 

 loam is a brown, loamy, medium sand, 6 to 8 inches deep. It is 

 somewhat more sandy than in either the Hartford or the Thoro- 

 f are area. The subsoil is a loamy yellow sand to a depth of about 

 18 inches, where it is underlain by a sticky, coherent, sandy loam 

 of a reddish-yellow color. This is locally termed a " clay." A 

 small amount of gravel is found in both soil and subsoil. 



The surface of the type is gently sloping to nearly level. Drain- 

 age is well established but is not usually excessive. 



Sassafras gravelly coarse sandy loam. — The Sassafras gravelly 

 coarse sandy loam occupies gravelly slopes and knobs. The surface 

 soil to a depth of 5 to 10 inches is a yellowish-brown sandy loam filled 

 with fine gravel. The pebbles range in size from one-fourth to 1^ 

 inches in diameter. The immediate subsoil is a yellow, gravelly 

 loamy sand or gravelly sandy loam. The deeper subsoil usually 

 consists of a somewhat compacted and dense gravel bed containing 

 only a moderate amount of finer grained material. 



The type occurs on slopes or as small knolls and knobs, and drain- 

 age is complete to excessive. 



Sassafras coarse sand. — The surface soil of the Sassafras coarse 

 sand, to an average depth of about 8 inches, is a brown to yellowish- 

 brown coarse sand. It is scarcely coherent and constitutes the most 

 sandy soil in the area. The subsoil, extending from a depth of 8 to 

 86 inches, consists of a medium yellow sand, slightly orange in color 

 in the lower depths. A small amount of fine gravel occurs in the 

 deep subsoil. 



The type occurs chiefly on low ridges associated with the Sassafras 

 coarse sandy loam and sandy loam. It is well to excessively drained. 



Sassafras fine sandy loam: — The surface soil of the Sassafras fine 

 sandy loam, to a depth of about 8 inches, is a brown fine sandy loam 

 containing small quantities of fine gravel. From 8 to 16 inches the 

 subsoil is a reddish-yellow, sticky, fine sandy loam. This is under- 

 lain to a depth of 3 feet or more by a stiff reddish-yellow clay. 



The surface of the type is gently sloping and the drainage is good. 

 The stiff subsoil interferes somewhat with internal drainage.
