form, and can be easily recognized, there are some localities where 

 the j are slightly lighter in texture, but their generally loamy, mellow 

 nature is noticed wherever the formation occurs. These soils have 

 for a long time been cultivated, and on certain portions of the for- 

 mation many prosperous farms are located. In other portions the 

 farms are largely in the hands of tenants, and although the soils are 

 productive, the general condition of these places is somewhat run 

 down and neglected. 



In good years from 20 to 25 bushels of wheat per acie can be 

 raised, but in poorer years 12 to 15 bushels are considered an average 

 crop. Corn will produce from 40 to 60 bushels per acre, about the 

 same yield as the Cecil loam. Oats will yield from 40 to 50 bushels 

 per acre, and good crops of clover and timothy hay are also raised. 

 Tomatoes are grown in small quantities with success on these soils. 



The following table gives the mechanical analyses of the soils and 

 subsoils :

NORFOLK SAND. 



The largest continuous area of Norfolk sand is just south of 

 Elkton, the county seat, and north of Chesapeake City. In addi- 

 tion to this large area the formation occurs as a fringe, varying in 

 width from one-fourth of a mile to slightly more than 2 miles, border- 

 ing all of the deeply indented river necks of the southeastern part of
