ENCYCLOPEDIA OF PRACTICAL HORTICULTURE 



COMPOSITION OF APPLES 



The following tables showing the com- 

 position of certain varieties of apples are 

 the averages taken from more elaborate 

 tables worked out by Alwood and David- 



son of the Virginia Experiment Station. 

 Apples vary in composition with the 

 variety and slightly with the environment. 

 This variation determines to some extent 

 the uses to which they shall be put.
