These figures show a considerable variation in the relative value 

 of beet pulp and silage especially in the first experiment. But in 

 this experiment the amount of hay fed was not constant, so that it 

 would ))erhaps be fairer to draw our conclusions fi-om the second 

 experiment where the other constituents of the ration were con- 

 stant and where the relation of the value of the two foods is much 

 more uniform. 



The low ratio given by Mollie is explained by the fact that she 

 ate a comparatively small quantity of beet pulp. Although her 

 average consumption of dry matter during the period of feeding 

 pulp was about IT pounds per 1,000 pounds live weight, still she 

 managed to produce nearly as much milk as during a period of simi- 

 lar length when on silage and averaging over 23 pounds of dry mat- 

 ter per 1,000. This is a forcible illustration of a fact that has been 

 frecpiently noticed, namely, that the ration of a well-nourished cow 

 may often be considerably reduced for a period of some length with- 

 out materially reducing the flow of milk. The average for eleven
