SOILS OF SOUTHERN NEW JERSEY AND THEIR USES. ‘ 
drainage is in many places excessive. The Lakewood sand, fine sand, 
and gravelly sandy loam have been mapped. The soils of this series 
are cultivated to only a small extent. 
Sassafras series.—The surface soils of the Sassafras series are dis- 
tinguished by a brown or yellowish-brown color and the subsoils are 
a deep yellow or reddish yellow. In many places a distinct bed of 
gravel or of coarse sand and gravel underlies these soils at a depth 
ranging from 24 to 5 feet below the surface. The series is found in 
all parts of southern New Jersey, in somewhat scattered occurrences 
in the Atlantic slope, but especially well developed along the Dela- 
ware River and in the plain which extends between Trenton and 
New Brunswick. Most of the types in this series are well drained. 
The types of the series include the Sassafras coarse sand, sand, loamy 
sand, fine sand, gravelly sandy loam, coarse sandy loam, sandy loam, 
fine sandy loam, and loam. 
Collington series—The ~surface soils of the Collington series 
usually have a rather dark brown color and the subsoils are of a 
vellowish to greenish brown. The series is marked by the presence 
of glauconite or greensand in the subsoils. It occurs chiefly along a 
narrow belt extending southwestward from the vicinity ef Atlantic 
Mighlands nearly to Salem. This belt varies from 1 or 2 to nearly 
15 miles in width. It is not entirely occupied by soils of the Colling- 
ton series. The surface features of the soils of this series are varied, 
ranging from gently sloping or nearly level to distinctly hilly and 
broken. Probably 60 per cent of the area of these soils is sufficiently 
level to meet the requirements of cultivation. Drainage is well estab- 
lished over the greater part of the soils of the series, being defective 
only in the case of the heavier soils. The series includes the Colling- 
ton sand, loamy sand, sandy loam, fine sandy loam, gravelly loam, 
loam, clay loam, and clay. The sandy loam and fine sandy loam are 
most extensive and of greatest importance agriculturally. 
Colts Neck serics—The soils of the Colts Neck series are char- 
acterized by the brownish-red to dark-red color of the surface soils 
and by the bright to deep red color of the subsoils. They occur 
typically in the hilly to undulating areas of the marl belt and are. 
well drained and easily tilled where the surface slope is not too 
great. The series includes the Colts Neck gravelly sand, loamy sand, 
sandy loam, fine sandy loam, and loam. 
Norfolk series —The soils of this series are marked by the grayish 
color of the surface soils and by the yellow color and friable struc- 
ture oi the subsoils. Only the Norfolk fine sand has thus far been 
encountered in southern New Jersey. It is usually hilly to rolling, 
well drained, and for the most part forested. Only the more level 
areas are occupied by farms,
