crop grown. The analytical work connected with this experi- 

 ment will be completed during the next two months, and re- 

 sults will be forwarded to the chairman of the committee of the 

 association. 



During the year three series of pot experiments, two of rape 

 and one of millet, each comprising 46 pots, have been com- 

 pleted in the study of this same phosphoric acid availability 

 problem. Considerable analytical work still remains to be done 

 before results will be available to the association or for publica- 

 tion. 



3. Feed and Dairy Section. 



A summary of the work of the feed and dairy section in 

 charge of Mr. Smith, assisted by Messrs. Beals, Borden, Davis 

 and J. B. Smith follows: — 



(a) The Feeding Stuffs Law (Acts and Resolves for 1912, 

 Chapter 527). 



During the past year 1,109 samples of feeding stuffs were 

 collected at 170 different places of business. Thirteen hundred 

 and thirty-six brands of feeding stuffs have been registered 

 and permits for sale issued. 



There have been no local prosecutions, but in several in- 

 stances samples of interstate shipments have been taken and 

 forwarded to the Bureau of Chemistry at Washington for ex- 

 amination and prosecution if the evidence warranted. 



The cottonseed meal situation during the past season has 

 been most discouraging for the feeder. Never before has the 

 general quality of the meal been as poor nor the price as high. 

 The poor quality has been due, in part, to the fact that prac- 

 tically all of the lint has been removed from the seed and used 

 for the manufacture of gun cotton. The removal of the lint 

 prevents the hulls from matting together, and allows them to 

 slip through the sieves during the process of separating hulls 

 and kernels, thus increasing the proportion of hulls in the meal 

 and materially reducing the protein content. 



At the present time (December, 1916) the price of com- 

 mercial feeding stuffs has reached what is probably the highest
