The results obtained in these trials have not been very encotiraging. 

 The fields in which the corn grew in 1909 and 19 10 were not well adapted 

 to corn, and the seasons were too cool and too dry for good corn-growing. 

 The advantage of soy-bean-and-com fodder in composition seems slight, 

 and in average yield the advantage is with corn alone. A separation of 

 the bean plants from some bundles of the mixed fodder in 1909 indicated 

 6 per cent of bean fodder in the mixture. It was lower, rather than 

 higher, in the other two years. The mixttire has not proven a success on 

 the university farm when grown in that manner. 



In 191 1 equal quantities of soy beans and corn were mixed and planted 

 in check rows about May 12. Hand planters were used to drop the seed. 

 The beans came up and flourished with the com in a few favored parts of 

 the field. The stand of corn varied from o to 5 stalks per hill, owing to 

 the varying proportion of com kernels and soy beans dropped in each hill. 

 On another part of the field where the com had made a good stand, soy 

 beans were planted by hand between the hills after the first cultivation. 

 A total failure of the beans resulted. They had no chance in competition 

 with the corn under such a handicap. 



The writer has failed to prove the real value of soy beans grown in corn- 

 fields for silage in the experiments just described. It therefore seems 

 desirable to quote from signed statements by our correspondents in regard 

 to their success with the mixed crop. The names of these correspondents 

 are withheld out of consideration for them. Any reader desiring to com- 

 municate with certain of them should write for their names to the author 

 of this bulletin. 



A florist at Hamilton, N. Y., who owns a farm that is occupied by a 

 tenant, writes: 



" As to varieties, we use the Early Green as the others will not mature 

 here. We formerly used the Leaming and Pride of the North com but
