Table i. Average Percentage Digestibility of Timothy Hay. 



The differences between the two animals shown by the fore- 

 going table are so small as to be scarcely significant, but if anything 

 seem rather in favor of the scrub animal, especially during the first 

 two years. At any rate the figures give no evidence of the posses- 

 sion of any higher digestive power by the pure bred animal. 



Digestibility of Grain. The digestiblity of the grain was de- 

 termined in the usual way by a difference computation. The re- 

 sults as between the two trials made in each year were somewhat 

 fluctuating, although the differences were not larger than might be 

 expected. The average results for the digestibility of the grain are 

 shown in Table 2.
