Another prominent apple growing region T& in the 
northwest is the Hood River Valley in Northern Oregon* 
This Valley has a rainfall equal to that in New York 
SE& differing widely from the Wenatchee and Yakima Val¬ 
leys. In spite of this fact irrigation has been found 
advisable and is common in most of the orchards. Due 
to the fact that light bearing varieties, such as the 
Yellow Newtown and Spitzenburg predominate, the yields 
do not compare with those in the important valleys in 
the state of Washington. 
In order of importance the principal apple growing 
states in the Northwest are Washington, California, Ore¬ 
gon, Idaho, and Colorado. Small areas in other western 
states may be found in Utah, Montana, and New Mexico. 
The unusual development in all of these states reached 
its height during the decade from 1900 to 1910 when many 
important public and private irrigation projects were 
completed. 
By ignoring state lines we find that the leading 
apple districts of the West are as follows:
