Delay in the Publication of the Analyses. 



L'nder the law it is the duty of the Commissioner of Agricul- 

 ture to collect the samples of fertilizers, and it is the duty of 

 the Director of the Station to make the analyses. The collection 

 of samples usually begins by Alarch 10 and ends by May 25. 

 This year (1915) the first samples were received April 5, and 

 the last sample September 17. It was not possible to complete 

 the analyses until the end of September. The reports of the 

 analyses were sent to the Commissioner of Agriculture fro'n 

 time to time during the summer as they were completed. 



The samples as received at the Station were identified by 

 number, but without information as to the brand, the guaranty, 

 and the maker. This information for most of the samples was 

 received at the Station October 13 but the data for the last of 

 the samples were not received until November 19. 



As the results could not be put in tabular form for printing 

 until after all the data were at hand, the copy for the tables 

 could not be sent to the printer until late in November. The 

 law requires the Director of the Station to "publish the official 

 bulletin giving the results of analyses that are deemed of public 

 importance annually in the month of October." It Avas impos- 

 sible to comply with the law the present year for the reasons 

 stated above. As it takes from 8 to 10 w^eeks from the time 

 the copy is sent to the printer before the completed pamphlet is 

 received from the binder, the fertihzer analyses for 191 5 will 

 be distributed about 3 months late.
