 hay of aver.ipe quality con- 

 tains say 7A% of digestible 

 protein, 11.7'?' of digestible 

 fiber, 26.3^ of digestible car- 

 bohydrates other than fiber, 

 and 1.9'^ of digestible fat. 

 Then 2}^ times 1.9 is 4.3; 

 to this is added 11.7 and 2G.3, 

 making in all 42.3, or the 

 starch -equivalent of all the 

 beat- and fat-forming nutri- 

 ents. Then 42.3 divided by 

 7.4 equals f).". The nutritive 

 ratio of clover hay is, there-
