greater than the average of the upland soils. They are strong soils, 

 which hold moisture and fertilizers well. In many respects they 

 resemble the Cecil clay, but the subsoils of these clays are of a 

 peculiar shade of red, and the soils are not as productive as the 

 Cecil clay. They will produce good crops of tomatoes and corn. 

 Wheat, for some reason, will not yield as well as on the Cecil clay 

 or Cecil loams, but it is rotated with the other crops. The forests 

 consist of a heavy growth of hard wood. 



The following table gives the mechanical analyses of the soil and 

 subsoil of the Conowingo clay:

SASSAFRAS LOAM. 



The largest areas of Sassafras loam are found on the Sassafras 

 Neck, Middle Neck, and the old historic Bohemia Manor, but there 

 are also areas of considerable importance north and northeast of 

 Elkton and east of Perry ville. This formation, unlike any of the 

 preceding, lies entirely within the borders of the Coastal Plain 

 country. It occurs in the southern part of the county as broad, 

 gently rolling terraces, from 40 to 80 feet above mean tide-level. In 

 the central portion of the county the formation occurs as sloping 

 terraces, which rise from 40 to 240 feet above tide-level. In many 

 places these terraces are level, with almost no difference in elevation 

 for miles. This is especially the case in the neighborhood of War- 

 wick, on Sassafras Neck. Here the country seems to present the
