Norfolk silt loam. — A brown loam 10 inches deep, underlain by 

 a heavy yellow loam subsoil, both containing a rather high per- 

 centage of silt. Occurs as level or gently rolling upland or ter- 

 races. Esteemed the most valuable soil of the Atlantic Coastal 

 Plain for general farm crojis. Adapted to wheat, corn, and grass. 

 In Xew Jersey this soil produces as high as 25 or 35 bushels of 

 wheat, 1 to 2 tons of hay, and from 50 to 70 bushels of corn per 

 acre. It is esteemed an excellent soil for dairy farming. On the 

 Eastern Shore of ]Maryland the yields are almost as high as in 

 New Jersey. In southern Maryland the yields are much less, 

 wheat producing from 12 to 18 bushels, and corn 25 to 40 bushels 

 per acre, while the yield of hay is proportionally small. It is 

 believed that this difference in productiveness is due almost en- 

 tirelv to the methods of cultivation.

« Mapped in part as Sassafras sandy loam and in part as Sassafras gravelly 

 loam, which names will hereafter only be vised in Maryland and New Jersey. 



b Mapped as Sassafras loam. It is recognized clearly now that this belongs 

 to the Norfolk series. The name Sassafras loam will be used hereafter only in 

 Maryland and New Jersey. 



<* Mapped in part as Sassafras loam and Sassafras gravelly loam. The latter 

 name will not again be used, and similar soils will in the future be mapped as 

 Norfolk silt loam with a gravel symbol and the gravelly phase described in 

 the report, except in Maryland and New Jersey, where it will be mapped as 

 Sassafras loam with a gravel symbol. The silt content of this soil, as shown 

 by the averages, is rather low for a .'Jilt loam, but in many individual .samples
