tour line of 1,000 feet elevation, commencing at the British boundary 
near longitude 122° and southward on said elevation to its intersection 
of the Southern Pacific Railway in the Upper Willamette Yalley, thence 
along the line of said railway to the Sacramento Yalley, 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 Yalley and the Sierra Nevada Mountains. An 
exception to the general recommendation will appear in certain portions 
of Snake River Yalley, where the vinifera grapes and other tender 
fruits succeed. 
District No. 16. — The coast section of British America west of longi- 
tude 122° and of Washington, Oregon, and California north of about 
latitude 39° 30', and bounded on the east by Districts Nos. 15 and 17. 
This district embraces the highly developed fruit-growing sections on 
Puget Sound, the Lower Columbia, and the Willamette. 
District No. 17. — 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 semi- 
tropical species and others in which the apple, pear, and other hardy 
fruits and nuts are grown to the highest perfection. 
District No. IS .■ — The coast section of California lying between lati- 
tude 35° and about 39° 30' and bounded on the east by District No. 17. 
Its characteristic features are the Coast Range of mountains, the 
Russian River, the Sonoma, the Santa Clara, and the Pajaro valleys. 
District No. 19. — 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 Yalley, San Diego, and many others. 
Districts 16 , 77, 18 , and 19 are peculiarly adapted to fruit and nut 
culture. Perhaps 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 are 
already felt and recognized the world over.
