of corn, wheat, clover, and grasses. Of these crops corn, clover, 

 and grasses give the best returns. Apples do well on this soil and 

 there are many small orchards on it. It is a soil which has to be 

 handled with considerable care. The loam is used for the produc- 

 tion of corn, wheat, grass, clover, apples, and small fruits. Grazing, 

 stock raising, and dairying are practiced on a small scale. With 

 judicious management good yields of corn, wheat, and grasses can 

 be secured. The sandy loam is a small and unimportant agricultural 

 soil. The greater part of it is in forest. This soil was formerly 

 used for wheat and tobacco, but now corn and wheat are the principal 

 crops grown. 



The Penn stony loam is of very limited extent and of little agri- 

 cultural importance. When the stones are removed corn, wheat, and 

 a few apples and small fruits are grown. The gravelly loam has a 

 very small representation in the State. It will produce corn and 

 wheat, but cultivation is difficult where the gravel is plentiful. 



York series. — The types included in the York series are gray to 

 light gray at the surface and have yellow subsoils. They are derived 

 from talcose and micaceous schists and imperfectly crystalline slates. 

 The texture and structure of the soil are unfavorable to the mainte- 

 nance of good tilth, as the surface bakes and checks readily, making 

 cultivation difficult. Crop yields are generally low, and the soils are 

 exceedingly difficult to improve. 



The York fine sandy loam is considered a thin soil, and small 

 yields of tobacco, corn, wheat, and oats are secured. This soil is 

 slightly less productive than the Louisa fine sandy loam. Heavy 

 fertilization is necessary to produce profitable crops. The York 

 loam is held in low esteem as an agricultural soil and practicall} 7 

 none of it is under cultivation. 



Worsham, series. — The soils of the Worsham series are composed 

 of light-gray surface soils and yellowish or mottled yellow, grr,:/. 

 and red plastic clay subsoils.' They occur throughout the Piedr o.r_c 

 region in comparatively small areas, in which, owing to the imper- 

 viousness of the subsoils, the drainage is poorly established. The 

 parent rocks consist principally of granite, gneiss, and associated 

 formations. The agricultural value of these soils is low and they 

 should be left in forest. 



The sandy loam, the only type so far mapped in the State, is of 

 very small extent. This soil is suited to the production of orchard 

 grass, herd's-grass, and timothy. On some small areas a heavy ship- 

 ping tobaco is grown. 



Conowingo series. — The Conowingo series is characterized by the 

 grayish-yellow to brownish color of the soils and the yellowish color 

 of the subsoils. Some areas mapped have a red subsoil and represent
