There has been a gradual increase in the digestibility of the 
rations of hulls and meal with the increased addition of meal. The 
digestibility of the dry matter of the 1 to 7 ration was 45 per cent., 
of the 1 to 6 ration 49 per cent.,* of the 1 to 4 ration 53.5 per cent. 
This increase here, as with the rations of silage and meal, is in excess 
of the average between the digestibility of hulls alone and of meal, 
as obtained from the rations referred to. 
The results upon this point for the ration of 1 to 4 are contained 
in the table herewith (XXXII[).

The nutritive ratio of the 1 to 4 ration of meal and hulls is one 
wider than the 1 to 12 ration of meal and silage. The increase in 
the digestibility of the 1 to 12 combination of meal and silage by 
both steers, and of the 1 to 4 combination of meal and hulls by 
Yellow Steer is practically the same, while the increase with Line-
