THE SELECTION OF VARIETIES 201 



CoIorado.-^-Thh state has several dififcrent ajjple 

 districts quite different in their character and require- 

 ments. The varieties mostly grown, however, are 

 those of Kansas — that is, Ben Davis and Gano, Grimes 

 and Jonathan, with Winesap, Rome Beauty and 

 Wealthy following-. 



The Pacific Coast. — While the Pacific coast, from 

 British Columbia to California, is a large district, and 

 while the apple-growing localities are widely sepa-

 same throughout the area. Yellow Newtown and 

 Esopus Spitzenberg are the leading varieties, but they 

 are closely followed by Jonathan. Then comes Belle- 

 llower, Arkansas Black and Winesap, with a few other 

 varieties of decidedly minor importance. 



KEEPING QL'ALITY OF VARIETIES 



The behavior of different varieties in storage is a 

 matter of vital importance in the handling of the com- 

 mercial apple crop. The length of time to which ap- 

 ples may be expected to keep in merchantable condi- 

 tion is of especial interest. The following general 

 principles are fairly well established : 



1. Apples grown in a northern latitude or high al- 

 titude will keep longer than apples of the same variety 

 grown farther south or at a lower altitude, 



2. Apples from, old or mature trees will keep 

 longer than the same varieties grown on young trees. 



3. Fruit from sandy soil will usually keep longer 

 than the same sorts grown on clay or loam. 



4. Well-colored, well-ripened fruit will keep longer 

 in good condition than fruit not fully ripe. This is
