From these examples it will be seen that there is a rather 

 wide range of fruit soils, although as a rule those which ap- 

 proximate the following analysis are best adapted to most 

 fruits : 



Per cent 



Aggregate of all sands 20-50 



Silt 20-50 



Clay 10-30 



Hall and Russell give the following as an ideal fruit soil: 



Per cent 



Fine gravel 1.0 



Coarse sand 6.8 



Fine sand 42.0 



Silt 23.3 



Fine silt 7.3 



Clay 10.9 



116. Orchard soils. — Since an orchard soil is judged 

 more from its mechanical make-up than from its chemical 

 constitution, it may be well to define further the types best 

 adapted to the several fruits. It is impossible to state within 

 narrow limits just what may be termed an orchard soil. 

 Indeed, perhaps a fourth or a third of the arable land of this 

 country might be used with considerable success for orchard- 

 ing if other factors were favorable. While analyses have 

 been given of a few typical orchard soils, the list might be
