minor investigations executed from time to time by this de-

Composition of Sunflower Seeds. 



The work on composition of sunflower seeds was practically 

 all done in 1898, by Messrs. Howard and Vickery, at the time 

 assistants in the department, but the results have not been pub- 

 lished. Three lots of Russian sunflower seeds were used, two 

 of which were raised at the station, while the third was fur- 

 nished 'by Mr. A. Z. Norcross of Rindge, a member of the New 

 Hampshire College class of 1899. One lot of the seeds grown 

 at the station was black and the other striped. The seeds 

 grown in Rindge were striped and had been picked prematurely, 

 so that they were lighter in weight than the station lots. 



The seeds were separated into hulls and meats, which were 

 analyzed separately, in addition to the analysis of the seeds as 

 a whole. 



The analytical results are given in the following tables:
