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- 

 tion as the crop. Phosphoric and sulphuric acids were 

 much increased in quantity above the other ash constituents. 

 The ash of the air-dry clover hay was :

From an inspection of these tables it will readily appear 

 that the sulphates checked the development of the flowers 

 and also of seed. A larger crop of leaves and stems may 

 be secured by the application of gypsum, but not of seed, so 

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

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