think of each listed variety as having the status of 

 an individual rather than that of a race. 



The diversity of individul types becomes ex- 

 plicable if we consider the history of their devel- 

 opment. The apple has been under cultivation 

 for some thousands of years. It has qualities that 

 have made it a favorite with successive generations 

 throughout the entire period. It has been taken 

 everywhere with migrating races of men it was 

 brought to America, for example until it girdled 

 the globe and found its way almost to the Arctic 

 Circle. 



The different races of apples thus developed 

 have been from time to time intermingled through 

 migrations of the peoples who cultivated the fruit, 

 many of whom, doubtless from the earliest period, 

 carried it with them in a dried state on their voy- 

 ages, and thus incidentally transported its seeds 

 and carried it into new regions. 



The varieties thus brought together have been 

 cross-pollenized by the bees, and so the tendency 

 to vary and to keep a great variety of ancestral 

 traits in evidence has been perpetuated. 



Finally, in modern times there has been per- 

 haps more attention given the apple by the horti- 

 culturist than to any other single orchard fruit.
