As we wished to make a comparison between the digesti- 

 bility of first and second cutting, it was decided to carry on 

 the work with alfalfa hay the second year, taking up the ex- 

 periments with first cutting and again with second cutting 

 from the same plot of ground. During the summer an attempt 

 was made to carry on a digestion experiment with green al- 

 falfa to make comparisons between the digestibility of that and 

 the alfalfa hay cut from the same plot of ground at the same 

 time. The forage was cut, placed in cold storage and the ex- 

 periment with the green feed begun, but by the time the pre- 

 liminary feeding was nearly over the fodder had begun heating 

 to such an extent that the experiment had to be abandoned. 

 The cooler was evidently too small to preserve the amount of 

 green fodder necessary for the experiment.
