The nature of this work is such that uo permanent results 

 can be secured from one or two seasons' operations. The element 

 of time is an all-essgntial one for the solution of such problems. 

 This would be true even though the problem was merely the 

 development of wheats giving higher yields than those now being 

 grown in the State, but ivith the introduction of the problem of 

 increasing the gluten content, the element of time is even of 

 greater importance. With this in view, the experiments were 

 so planned that while the final results could not be expected for 

 several years, it was possible to obtain data of importance bearing 

 upon the entire question of cereal culture each year, material 

 progress thus being assured. 



As early as 1882 Clifford Richardson called attention to the 

 fact that wheats from the Pacific Coast were relatively low in 

 their protein content, and numerous analyses of California 

 grown wheats made at the California Agricultural Experiment 

 Station under the direction of Dr. E. W. Hilgard, in the earlier 

 years, also showed the same condition to exist. 



That this condition exists is undoubtedly true, whatever the 

 causes may be. To bear witness to the fact the following sum- 

 mary is given of anal3ses of white wheats grown in several 

 different states, as compared with the analyses of 149 samples 

 of wheats of the same class grown in California in the same 

 years. For the sake of comparison also the average results 

 obtained from the analysis of 49 hard winter wheats grown in 

 Kansas the same season are included, as well as those of three 

 soft white wheats grown in Kansas from seed originally obtained 

 from the state of Washington.
