A comparison of the composition of green rye with that of 

 Italian rye-grass will show that both possess about equal nutritive 

 value. Green rye, it thus appears, is inferior to the better sorts 

 of clover as a feeding-stuff. 



IL COMPOSITION OF RAPE. 



Water. (a..) In leaves. The proportion of water varies to 

 some extent in rape, as will be seen by the following determina- 

 tions, which indicate the amount of water in different samples of 

 rape-leaves, taken from the field at different periods : 



1. Per-centage of water,

 the amount of water was

The stems are thus more watery than the leaves. 

 (c.) In roots. 



Per-centage of water, 

 The first determination was made with a sample of the more lig- 

 neous older roots, the second with the more tender young roots. 



Ash. (a.) In leaves. The proportion of ash in different samples 

 of fresh leaves was found as follows :
