Sampling Feeds and Milk. 



The hay was sampled at the beginning and end of each half 

 of the trial in the usual way, as described in other experiments 

 of this character. The grains were sampled daily and the 

 samples preserved in glass-stoppered bottles and brought to the 

 laboratory at the end of each half of the trial for dry-matter 

 determinations and complete analyses. 



The milk of each cow was sampled daily for five consecutive 

 days on the first, third and fifth week of each half of the trial. 

 The usual method of sampling was followed.
