POMOLOGICAL DISTRICTS. 13 



contour line of 1,000 feet elevation, commencing at the British 

 boundary near longitude 122° and southward on said elevation to its 

 intersection with the Southern Pacific Railway in the upper Willamette 

 Valley, thence along the line of said railway to the Sacramento 

 Valley, thence east and south on the eastern rim of said valley and 

 that of the San Joaquin at an elevation of 1,000 feet to latitude 35°, 

 thence east on said latitude to the Colorado River. The characteristic 

 features of this district are the upper Columbia Valley and the Sierra 

 Nevada Mountains. An exception to the general recommendation 

 will appear in certain portions of Snake River Valley, where the 

 vinifera grapes and other tender fruits succeed.^ 



District No. 15. — The coast section of British America west of 

 longitude 122° and of Washington, Oregon, and California north of 

 about latitude 39° 30^, and bounded on the east by districts 15 

 and 17. This district embraces the highly developed fruit-growing 

 sections on Puget Sound and the lower Columbia and the Willamette 

 rivers.^ 



District No. 16. — The Sacramento and San Joaquin valleys, 

 bounded on the east by District No. 15 and on the west by the 

 western rim of this great interior basin. The diversified fruit and 

 nut products of this district are marvelous. There are localities in 

 which the semitropical species and other places where the apple, pear, 

 and other hardy fruits and nuts are grown to the highest perfection.^ 



District No. 17. — The coast section of California lying between 

 latitude 35° and about 39° 30' and bounded on the east by District 

 No. 17. Its characteristic features are the Coast Range of raountains, 

 the Russian River, and the Sonoma, the Santa Clara, and the P^^jaro 

 valleys.^ 



District No. 18. — California and Arizona south of latitude 35°. 

 The dominant characteristics are the valleys of the Gila, the Colorado, 

 the San Gabriel, and the Santa Ana, and the Sierra Madre Mountains. 

 It includes the celebrated fruit districts of Santa Ana, Riverside, 

 Santa Barbara, the Salt River Valley, San Diego, and many others.^ 



« Recent developments of the fruit industry in several isolated localities in District 

 No. 14 have demonstrated the fact that many of the deciduous fruits can be grown 

 with perfect success. This is especially the case in the Hood River and Rogue 

 River valleys in Oregon, in the Wenache and Yakima valleys in Washington, and 

 in other favored sections. ' 



b Districts 15, 16, 17, and 18 are peculiarly adapted to fruit and nut culture. Per- 

 haps no portion of the earth's surface is more highly favored in climate and soil and 

 affords a wider range of crop products than that lying within the boundaries of these 

 four districts. The commercial value of the fruit and nut products of this section 

 is recognized the world over.
