we meet with the following differences in one and the same species 

 of clover : 



The percentage of water in the various clovers on an average 

 amounts to : 



Per Cent. 



According to Anderson 80 83 



Voelcker 78-65 



Way 78-24 



The amount of flesh-forming substances in the dry clovers on 

 an average is 



According to Anderson 14-40 



Voelcker 19-44 



Way 19-31 



I purposely abstain from drawing any practical deductions 

 from these analyses ; for although they show that some species 

 of clover are more nutritious than others, it does not follow that 

 this will be the case under all circumstances. It indeed appears 

 to me that the quality of the clover depends not so much upon 

 the species cultivated as upon the time when it is cut down, and 

 on the nature of the land on which it is grown. On one kind of 

 soil, it is more than probable that a particular species of clover 

 will delight more than another, and that consequently a great 

 difference in the nutritive value of the same kind of clover will 

 be observed when cultivated on land naturally suited for it or 

 otherwise. The period at which clover is cut down especially 

 affects its value. It has been observed already that young clover 

 is always richer in flesh-forming substances, and contains less 

 woody fibre than old clover, for which reasons it is more nutri- 

 tious. Under the head of clover-hay, I shall mention the details 

 of some direct experiments made in 1851 by Stockhard and Hell- 

 riegel, which show how great is the influence of the time of 

 cutting clover for hay on its nutritive qualities.
