REPORT OF THE DIRECTOR. 



The work of the station during the past year has followed 

 the usual lines. There has been some increase in the amount 

 of research work. This has been made j)ossible by the increase 

 in the amount received from the Adams fund for the current 

 year. Especial attention is called to the fact that innnediate 

 results cannot in most cases be expected from such fundamental 

 scientific investigations as are allowed under the Adams fund. 

 A number of important problems arc receiving most careful 

 investigation and study. Among them, the more important 

 are the following : — 



Studies in milk secretion. 



Molasses and digestion depression. 



Why arsenicals burn foliage. 



Plant breeding, and subsidiary thereto, variation in garden peas and 

 ai^ples. 



Determination of physiological constants. 



Investigation to determine the economic importance of digger wasps 

 in relation to agriculture. 



Studies of pyrallidse and tortricidae. 



Experiments to determine the plant food requirements of asparagus. 



Cranberry investigations to determine plant food requirements. 



Relations of climate to plants in health and disease. 



Cranberry insect work. 



In some of the investigations, results, from which practical 

 lessons which seem to be of importance even now, have been 

 obtained; but no one of them has yet been carried to comple- 

 tion, and most of them are of such a nature that long and 

 patient research will undoubtedly be essential before the funda- 

 mental laws which determine the results can be determined.
