EXPERIMENT STATION RECORD. 



The beans bloomed and fruited in the white as well as in the red hot- 

 house, but perished in the green and blue. Peas bloomed in all hot- 

 houses except the blue, where the plant did not grow any during the 

 two months of the experiment. The peas in the green house remained 

 in bloom for three weeks without fruiting. Only those in the red 

 and white houses fruited. 



The following assortment of vines was placed in each of the hothouses : 

 One of Chasselas, two of Frankenthal, and two of Melinet. The Chas- 

 selas, and one vine of Frankenthal, were planted in 1894, the vines of 

 Frankenthal and Melinet, in 1895. Beginning with April 10, a dirler-

ence in development could be noticed, due to the unequal temperature 

 of the hothouses. The vines in the white and red houses started earli-
