This shows that the action of the sulphates increased the 

 woody fibre at the expense of the flowers and leaves. The 

 relative proportion of flowers, leaves and stems was : 



The entire crop on each plat was as follows : 



The ash constituents were increased in the same propor-

 The ash of the air-dry clover hay was : 



From an inspection of these tables it will readily appear

 that an application of gypsum is not favorable for the de- 

 velopment of the seed crop, but well suited to increase the
