than the corresponding members of the Marshall series, but they do not pro-

"The clay loam is the most important for general farming, and forms the 

 principal type of soil in western Ohio and central and eastern Indiana. It is 

 especially well adapted to small grain and grass crops. The silt loam is more 

 rolling and hilly than the clay loam and is not so well suited to general 

 farming. Wheat does better upon it than upon the Marshall silt loam, with 

 which it is closely associated, but the yields of corn are considerably less. 

 It is also well adapted to fruit, especially apples. The sandy loam and fine 

 sandy loam are used for general agriculture, but are especially adapted to me- 

 dium and late truck crops and fruit. The loam is suited to corn and potatoes, 

 while small grain and grass are grown, but with less success than upon the clay 

 loam. Strawberries and raspberries, as well as other small fruits, do well on 

 this type. The stony sand, gravelly sand, and gravel are not of much agricul- 

 tural value under present conditions. The stony loam is a good general farm- 

 ing soil, is also well adapted to apples, and furnishes excellent pasture, while 

 in New York alfalfa is grown upon it very successfully. The stony sandy 

 loam and gravelly sandy loam are not strong soils, but are fairly well suited 

 to light farming, fruit, and truck. The sand and fine sand are not adapted 

 to general farming, but are the best early truck soils of this section. 



"The acreage of the different types so far encountered is shown in the 

 preceding table." 



silt loam, and that mapped as Miami silt loam in Clinton and St. Claire counties, 

 Illinois, is Marshall silt loam. 



7 The soil mapped as Miami clay loam in Toledo area, Ohio, is Dunkirk clay 

 loam, and that mapped as Miami clay loam in the Stuttgart area, Arkansas, is 

 Crowley silt loam.
