It is evident that the cows made but little better use of the branch 

 grass tliau did the sheep. Making the calculation explained under 

 black grass, we find it to be 24 per cent less valuable than English 

 hay. If the variation in live weight could also be brought into the 

 calculation there would be a still greater difference. Sheep showed 

 a 32 per ceut difference. We are confident, however, that had the 

 branch grass been in as good condition as the fox grass, it would 

 have produced equally good results.

Experiment IV. 

 Red top variety vs. English hay. Average results with 4 cows 

 for 14 days. This hay was very dry, but woody and tasteless, and 

 the animals showed no particular relish for it. They consumed how- 

 ever their entire daily ration.

* In figuring these rations, the coefficients of digestibility obtained with sheep 

 on branch grass were employed, hence the noticeably less amount of total diges- 

 tible matter in the branch grass ration.
