EXPERIMENT III. 

 Alfalfa Hay (Second Cutting). 



The alfalfa for this experiment was grown upon the ranch 

 of Mr. C. P. Arnold, under the Pioneer Canal, near Laramie. 

 It was of the crop of 1904. Time of cutting" unknown, but was 

 well cured and good alfalfa hay. Wethers were on alfalfa 

 since preceding experiment. Preliminary feeding began March 

 13, 1905. Feed was cut into sacks as already described. Sam- 

 ples were taken by catching a portion from the cutter between 

 each sack. The feed sacks were weighed on the same day as 

 sample. It has been found that this method is the simplest 

 and most satisfactory method of sampling, and all other sam- 

 ples of feed for experiments enumerated in this bulletin have 

 been sampled in this manner. The principle is not a new one, 

 but has been used a great deal for sampling of other material 

 than feed.
