Collington gravelly sandy loam. — The surface soil of the Colling- 

 ton gravelly sandy loam, to a depth of about 6 inches, is a brown 

 sand, well filled with small white quartz pebbles. The subsoil, to a 

 depth of about 24 inches, is a greenish-yellow gravelly sand. It is 

 usually compact and so filled with gravel as to.be almost impene- 

 trable. This rests upon a greenish-yellow sticky sandy loam or upon 

 the unweathered greensand at a depth of about 24 inches. 



The type occurs as narrow bands and small scattered areas asso- 

 ciated with the Collington fine sancry loam. 



Where the type occurs as narrow belts in better arable soils it is 

 tilled. Along the margins of areas or on stream slopes it is usually 

 left in forest. 



Portsmouth sandy loam. — This type is the same as described in the 

 Hartford and Thorofare areas. It occurs only around stream heads 

 where drainage has been partially established. Where drained it is 

 used for growing general farm crops. 



Small areas of the Hyde sandy loam, of the Freneau sandy loam, 

 and of fresh-water swamp were also mapped, together with the up- 

 land types. They are chiefly or entirely used for pasture and their 

 area is not considered in detail in the discussion of the upland soils 

 and their crop uses. 



The total and relative areas of the diiferent upland soils is shown 

 in Table VIII :

It will be observed that while there is a considerable variety both 

 in the origin and in the texture of the different soils as mapped, yet 

 the area as a whole is dominated by sandy and sandy loam soils, and 

 that the soils of the Sassafras series are of the greatest importance, 

 two types of that series comprising 63.1 per cent of the total area 

 mapped. The Colts Neck loamy sand and the Collington fine sandy 

 loam are the only types of any extent which do not fall within the 

 limits of the Sassafras series. Nearly 76 per cent of the total area
