EXPERIMENT II. 

 Alfalfa Hay (Second Cutting). 



This alfalfa was practically the same as that used in Ex- 

 periment I. Wethers were fed on alfalfa hay since the preced- 

 ing experiment. Preliminary feeding was begun February 17, 

 1905. For two days seven-eighths of a pound was fed twice 

 daily, then increased to one pound and preliminary continued 

 for five days. Sacks were put on February 24 at 8 a. m. and 

 experiment closed March i, at 8 a. m. 



The hay was cut for feeding as in the preceding experi- 

 ment. Sample was taken by removing a little from the top of 

 each sack immediately after cutting. Four samples were made 

 up, each representing a composite sample from ten sacks and 

 analyzed with the following results :
