Comparison of Timothy and Clover Hays. 



It appears from the above figures that the dry substance of the 

 Timoth}' hay proved to be nearh' as digestible as that of the clover. 

 Moreover, the digestibility of the several ingredients is not re- 

 markabl}'^ unlike in the two hays. Tliere is, however, an important 

 difference in the amount of certain kinds of material that was di- 

 gested, which is due to tlie unlike composition of the hays. The 

 small lots of ha}' used in the digestion experiments were selected to 

 represent as nearly as possible large lots of hay that were in each 

 case the product of one acre. An acre of pure Timothy grass and 

 an acre of nearl}' pure alsike clover were cut and stored separately. 

 The two lots were weighed when housed, and again on Dec. 20th. 

 "We have therefore the following data, from which we can reckon 

 the amounts of digestible material of various kinds, per acre : 



(1) The composition of the dry hays. 



(2) The digestibilit}' of the several ingredients of the hays. 



(3) The production of dry hay per acre. 



The composition of the hays as shown in the previous fodder 

 analyses is given in this connection. 



The yield of dry hay from the acre of Timothy was 3875 pounds, 

 and from the acre of clover, 4075 pounds, the difference being only 

 two hundred pounds. They were representative lots of grass with
