should be provided at points which would not necessitate long journeys 

 on the part of stock to secure drink. By proper treatment ranges 

 which still have a sufficient supply of grass left to reseed them maj^ be 

 reclaimed by disking and allowing a period of rest or Iw alternating 

 periods of pastiu'e and rest, allowing the grasses to produce seed. 

 Where there are facilities for irrigation there is little trouble in the 

 selection of good forage plants. Alfalfa can be successfully grown in 

 most portions of the region. In the Santa Cruz Valley barley is grown 

 extensivel}' for green feed and hay. Alfalfa is also an important crop 

 here. The different varieties of nonsaccharine sorghums and also the 

 millets may be prohtabh^ produced under irrigation. 



THE PACIFIC COAST. 



CONDITIONS AND PROBLEMS. 



The Pacific Coast region, as discussed here, will l>c confined to the 

 countr}" lying west of the Cascade and Coast Range mountains. There 

 is considerable variation in the climatic conditions at various points in 

 this region. For instance, near the southern part of California the 

 annual rainfall averages 10 inches, while on the coast of northwestern 

 Washington there is a small area having an annual rainfall of 100 

 inches. From San Francisco northward, however, the differences are 

 not so great, the annual precipitation varying from 30 to 100 inches. 

 The rainy season in this region is during the winter, the greatest rain- 

 fall occurring in December and January, with a rapid decrease of pre- 

 cipitation as the spring and summer advances, so that during June, 

 July, and August there is little and sometimes no rain. It will he 

 noticed that over the greater portion of this region there is a sufficient 

 moisture supph' to meet the needs of most forage plants, so that it is 

 onlj'^ in vcr^^ limited areas that arid conditions are to be met with. 

 The real range lands here are quite restricted as compared with those 

 in the Great Basin and Rocky Mountain region, as there are extensive 

 forest areas all along the coast. There are, however, frequent open- 

 ings in the woodlands which are termed '"prairies," and in many places 

 open or brush-covered range lands in the foothills and mountains. 



The dairying industry is perhaps the most important one in this 

 region. Stock growing, however, assumes consideralile importance at 

 certain points in California and Oregon, 



The control of the shifting sands, which arc menacing and in man}' 

 places destroying the agricultural lands at certain points along the 

 coast, is a matter of great importance. 



WORK DONE. 



Considerable work remains to be done here, as there has been 

 opportimity thus far to do but a limited amount of investigation.
