cated by the decreased number of samples that failed to be as 

 good as the guarantee. There has been a considerable decrease 

 in the amount of mixed feed stuffs consumed in the state, partly 

 due to the large corn crop raised the previous year, and partly 

 due to the fact that we have continuously urged the people to 

 grow their feed at home. The effect of the boll weevil on 

 the cotton crop has also aided in bringing about the home pro- 

 duction of our supply of feed stuff's. Very few samples of 

 Paris green have been analyzed, as there has been no considera- 

 ble amount of Paris green used, either for fighting the cotton 

 caterpillar or the boll weevil. Twenty-two hundred and ninety- 

 six analyses of fertilizers were made during the fiscal year, cov- 

 ering 5999 samples; and 4422 analyses of feed stuffs, covering 

 9381 samples. During the latter part of the year we con- 

 structed a fire-proof hood adjoining the main laboratory, thus 

 eliminating the very great danger of fire that has constantly 

 menaced us heretofore. The capacity is such as to also increase 

 the amount of work tliat may be accomplished in a given time 

 in the laboratory. We have been very fortunate in maintaining 

 a corps of chemists of high efficiency and exceptional devotion 

 to their work. In every instance arising in which there has 

 been a dispute over the result of analyses referees have verified 

 the result secured in the laboratory. 



Changes in staff: Mr. H. L. Green resigned to take up the 

 study of medicine and was succeeded by Mr. Gr. D, Cain. Mr. 

 R. E. Graham resigned as assistant chemist at Audubon Park 

 to take up the study of medicine. 



SPECIAL DEMONSTRATION TRAIN. 



From the second to the fourteenth of October, 1910, some 

 of the members of the Experiment Station staff and of the 

 University faculty, in co-operation with the Southern Pacific 

 Railway Company, operated a special train over the Southern 

 Pacific lines, in an effort to stimulate greater interest in diver- 

 sified farming and stock raising. The train carried two carloads 

 of improved agricultural implements, a carload of cattle, repre- 

 senting two breeds of beef type, the dual purpose cow, and the 

 dairy cow. Examples of the leading breeds of hogs were car- 

 ried in another car provided especially for exhibition purposes. 

 One passenger coach was transformed into a general exhibit
