^DISTRICT 3 



Figure 1. — Map of the Pacific Coast States and Arizona. District 1 — high 

 mountainous parts of Washington, Oregon, and California, which in general 

 are not suited for fruit growing. District 2 — mountain slopes and elevated 

 areas having a growing season of 90 to 150 days; only especially hardy and, in 

 some cases, drought-resistant varieties may be grown. District 3 — western 

 and river-valley areas of Washington and Oregon, foothill slopes in California, 

 and parts of Arizona having a growing season of 150 to 240 days, where 

 a considerable variety of fruits and nuts may be grown ; irrigation required east of 

 the Cascade Mountains in Washington and Oregon, in southeastern California, 

 and in Mohave, Yavapai, Gila, and Graham Counties, Ariz. District 3a — 

 rather narrow coastal strip of Washington, Oregon, and northwestern California 

 having the same length of growing season as district 3, but summer tempera- 

 tures too low for the best growth of many fruits. District 4 — northern and central 

 river valleys and coastal areas of California having a growing season of more 

 than 240 days; in the interior valleys high summer temperatures prevail, and 

 many fruits and nuts may be grown under irrigation. District 5 arid parts oi 

 southern California and Arizona having a growing season of more than 240 days 

 and high summer temperatures, where a considerable range o\' fruit varieties 

 may be grown successfully under irrigation.
