The upland rices show their derivation by 

 requiring somewhat moist soil, and they are not 

 grown to advantage in California, except in the 

 moist retentive soils of the Sacramento Valley, 

 and to a certain extent in the Coachella Valley. 

 In the former region, however, the growth of 

 the upland rice has proved to be exceedingly 

 profitable. 



I have tested different kinds of rice here on 

 several occasions, but the results were not such 

 as to induce me to continue its culture, the condi- 

 tions not being favorable. 



But the fact that varieties of rice have been 

 developed that grow on the upland gives assur- 

 ance that further development may be possible 

 in the direction of adapting the plant to general 

 cultivation on lands suitable for growing of 

 other cereals, as already demonstrated in the 

 South. Doubtless a good deal can be done also 

 to make rice a hardier plant through selective 

 breeding; and few attempts at plant develop- 

 ment could have greater importance, for rice is 

 a grain hardly inferior to wheat itself in nutri- 

 tional value, and one that might be cultivated 

 far more extensively in this country, to very 

 great advantage, 



My own experiments have had in view the 

 possibility of the development of the American
