SALEM SERIES. 



Soils of this series are derived from interbedded layers of sand- 

 stone, argillaceous and schistose rocks and a dense, close-grained 

 basalt, all highly ferruginous. 



Salem gravelly loam. — Brown or black loam containing a large 

 amount of gravel from 2 to 3 inches in diameter. This grades im- 

 perceptibly into a soil of the same material but containing more 

 gravel. A bottom soil generally well drained. Derived as a 

 stream wash from the same material as the Salem clay. Where 

 not too gravelly the soil is fairly well adapted to grain and fruit.

 inches deep, underlain by a coarse sandy loam grading into sand. 

 The surface soil usuallv contains considerable organic matter. A 

 bottom soil, subject to frequent overflow. Well drained when the 

 river is at normal stage. Forms an excellent truck soil. Gives 

 large yields of hops, but they are subject to disease.

Salem loam. — Brown to black loam 18 to 24 inches deep, con- 

 taining considerable organic matter, and being usually quite silty. 

 The subsoil is yellowish or red-clay loam or clay, becoming heavier 

 with depth, and often becoming mottled with gray and yellow. 

 Gently rolling or level valley land derived from transported sand- 

 stone material, with some basalt. Drainage generally good. Soil 

 is well adapted to general crops as well as to hops and small fruits. 

 Wheat produces from 25 to 30 bushels, oats from 35 to 60 bushels, 

 and hops about 15,000 pounds per acre.
