 long- process of selection and which is peculiarly 

 adapted to his soil and situation, and he regards it 

 as superior to the original variety, and that is often 

 true. (See Fig. 21.) Such strains, however, often

 grown under different climatic conditions. 



Varieties have their preferences as to soil and

 melon districts of the middle West, the Rocky Ford
