9fi EXPERIMENT STATION. [Jan. 



Only one Ayrshire breeder (G. E. Stone of Littleton) is at 

 present making a yearly test of his herd. 



The station has issued a speeial circular, giving breeders full 

 information relative to the making of such tests ; the circular 

 also states the rules and regulations governing the same. All 

 records, after being verified and sworn to, are forwarded to the 

 several cattle clubs and a duplicate copy kept on file at this 

 office. There have been completed during the year 5 Guern- 

 sey and 30 Jersey yearly records and 70 Holstein records (53 

 of which were of seven days' duration, 10 for fourteen days and 

 7 in excess of fourteen days). 



It hardly seems that it is the proper function of the experi- 

 ment station to do work of this kind, but it will continue to 

 give such matters attention until other facilities are provided 

 for the accommodation of breeders. 



10. Special Chemical Work. 



The station has co-operated with the association of official 

 agricultural chemists in studying the accuracy of methods for 

 the determination of nitrogen and in ascertaining the most suit- 

 able methods to be used in the analysis of condensed milk. 

 These results were reported to several referees of the association. 



Mention may also be made of a study to ascertain the best 

 methods to be employed in determining water and the several 

 sugars in molasses, also of a determination of the fat constants 

 of soy bean oil. These investigations will be published as a 

 part of this report or elsewhere. 



11. Work Completed. 

 Molasses and Molasses Feeds. 



The station has made a study of the value of molasses and 

 molasses feeds for dairy cattle, horses and swine, and has pub- 

 lished its findings, together with the most important results 

 seemed by German and French investigators, in Bulletin No. 

 IIS, which is now ready for distribution. 



The value of molasses was discussed under the following 

 headings: composition, effect of molasses on digestibility of 

 other feed stuffs, digestion coefficients for molasses, relative 

 values of molasses and corn meal, and the uses of molasses as
