BULLETIN 1189, U. S. DEPARTMENT OF AGRICULTURE. 



In the northern Panhandle of West Virginia the outlook for fruit 

 growing is not promising, because for a distance of 1 to 3 miles east 

 of the Ohio River soot from the chimneys of the factories along the 

 river covers the fruit while still on the trees and makes it necessary 

 to wipe the apples before marketing them. The fruit of some 

 varieties is so stunted in growth by the soot as to become almost un- 

 marketable. Aside from the soot, however, the conditions are favor- 

 able to orcharding. The Willowtwig is the principal variety grown. 

 Other varieties common in this section are the Ben Davis, Grimes 

 Golden, Baldwin, and Hubbardston. 



INTERIOR LOW PLATEAU REGION. 



PHYSICAL FEATURES. 



The Interior Low Plateau region occupies the greater part of Ken- 

 tucky and a large part of middle Tennessee. To the north it extends

 Plateau region. Part of these orchards are in sod, and only a space around each tree 

 is kept tilled. Compare with Figure 4. 



to and beyond the Ohio River in certain places. Its eastern boundary 

 is the western boundary of the Cumberland Plateau and Allegheny 

 Plateau regions. Southward it extends beyond the Tennessee-Ala- 

 bama boundary line and westward to the Tennessee River, which 

 forms the eastern boundary of a small section of the Gulf Coastal 

 Plains region. Many subdivisions of this Interior Low Plateau re- 

 gion could be made to correspond with the physiographic subdivi- 

 sions, such as the Highland Rim, the Nashville basin, the bluegrass, 

 and the western coal-fields sections. The pomological features of 

 these sections do not vary greatly at present, and the names are used 

 only for convenience in describing the region. 



The altitude of this region ranges from about 350 feet above sea 

 level along the river bottoms to more than 1,000 feet near the Cum- 

 berland Plateau region. The hills do not usually rise more than 100 

 feet above the surrounding country, though in certain localities 

 higher relative elevations occur.
