60 MASS. EXPERIMENT STATION BULLETIN 398 



Field Day. Because of the shortage of gasoline and tires, and the lack of farm 

 machinery for demonstration purposes, this annual meeting, which would have 

 been the twenty-fourth, was not observed. Special groups and individuals, 

 however, interested in certain particular experiments and trials visited the Station 

 at opportune times. Among them were the New England Carnation Growers 

 Association, Boston Market Gardeners Association, Greenkeepers Club of New 

 England, Society of American Florists and Ornamental Horticulturists, Massa- 

 chusetts Fruit Growers Association, U.S.D.A. Club, New England Seedsmen's 

 Association, and the New York-New England Fruit Spray Specialists.
