Fig. 62. — The West produced one-third of the apples grown in 1910 despite the fact 

 that it possessed only one-seventh of the acreage of bearing trees. Washington led all 

 States in production, with a total almost equal to that of New York and Virginia 

 combined. The three famous apple districts of Washington — the Yakima Valley, the 

 Wenatchee Valley, and Spokane Countv — stand out clearly on the map ; also the Hood 

 Eiver and Willamette Valleys of Oregon, the Boise, Idaho, district, the Sonoma Valley 

 in California, and the Grand Junction-Del ta-Montrose district of Colorado. In the 

 East, the New England area, the two noted New York districts, the Appalachian, the 

 western Michigan, the Ozark, and the northwestern Missouri districts are the most 

 Important. 



Fig. 63. — The commercial crop of apples in 1919 — that is, the quantity " sold or to 

 be sold " — was nearly 100 million bushels, according to the census, constituting three- 

 fourths of the total crop. The West produced over two-fifths of this commercial crop, 

 Washington alone reporting over one-fifth of the total quantity in the United States. 

 Eighty per cent of the commercial crop was produced in the 15 apple districts already 

 referred to. It will be noted that the production of the commercial crop of apples is 

 more concentrated than the total production, and the total production in turn, more 

 concentrated than the acreage. Diseases and pests diminish the production or tu« 

 nnsprayed home orchards several years before they kill the trees.
