From the previous tables we take the average amounts per day 
of these various constituents contained in the dry dung, and by a 
simple calculation determine the digestibility of orchard-grass 
hay, as plan ita the following table: :

An inspection of the previous table shows that the sample of 
orchard-grass hay used in these experiments was fully as digestible 
as timothy or any of our best upland hay. By chemical analysis, 
which gives us the potential and not the nutritive value of & 
fodder, it has proven itself for the past two years a more highly 
nitrogenous hay than timothy. A further study of the feeding 
value of the hay will appear under the topic, “Influence of Food 
upon the Milk and Butter.” 
- OrncHARD—Grass Hay anp Corn Meat FEED. 
As previously stated, during the second digestion experiment 
there was fed to each cow eight pounds of corn meal per day and 
a known quantity of hay, as shown in the previous tables. 
The details for the entire experiment having already been given 
in former pages of this report, we need here only present a sum- 
mary of the results showing the digestibility of the ration and of 
the corn meal in the ration. In this we assume, for the present,
