The above results show that when considered ton for ton of water 

 free matter, the black grass contained from 87 to 94 per cent as 

 much digestible matter as found in the English hay, the fox grass 

 from 88 to 91 per cent as much, a typical sample of branch giass 

 88 per cent as much, etc. We are therefore convinced that the 

 present digestion experiment with branch grass fails to express its 

 true value when in good condition. 



In order if possible to draw closer conclusions, let us consider the 

 digestibility of both the 1894 and the 1897 samples on the basis of 

 14 per cent water for the English hay, and 18 pei' cent water for 

 the salt grasses, these being the water percentages the several hays 

 would be most likely to contain under nalural conditions.

 with a ton of average English hay receiving similar treatment, and

We have therefore concluded that a ton of black grass hay con- 

 tains 10 per cent less nutritive matter, a ton of fox and branch 



* Red top variety contains but 13 to 14 per cent of moisture and hence sho"ws a 

 value about equal to branch grass. If it contained 18 per cent moisture, i. e. vas 

 as damp as other salt hays, it would show a relative value of 81.
