Percentage increase English over 

 Fox grass ration, -fl.O +1.07 +4.10 — 



Fox grass composed about 40 per cent of the digestible matter of 

 the ration and therefore calculated as explained under black grass, 

 a ton of dry fox grass would prove to be but 4 per cent less valuable 

 than a ton of dry P^nglish hay. The results with sheep show it to 

 be 9 per cent less valuable on the same basis. The above results 

 indicate that fox grass, if in good condition, did uearlj' as well in 

 the ration fed in the present experiment, as did English hay.

ItXPERIMENT III. 



Branch grass ration vs. English hay ration. Average results with 

 six cows for 21 da^^s. Attention has already been called to the fact 

 that this hay was quite damp and mouldy. In some cases we were 

 obliged to cut the hay, and mix the grain ration with it, before the 

 animals would eat it.
