EXPERIMENT STATION. 



[Jan. 



Summary of Coefficients, Period II. {Per Cent.). 



This corn is of substantially the same tyi)e as the one imme- 

 diately preceding. It appeared to be slightly less digestible, 

 althongh the ditference may have been partly due to the indi- 

 vidnality of the two lots of sheep. 



Alfalfa Hay. — The alfalfa hay used in these experiments 

 was grown on the college farm. It was cut while in early blos- 

 som, and was quite free from weeds and grass. Period III. 

 represented the first cutting of the third-year growth, period 

 IV. the second cutting of the third-year growth, and period V. 

 the first cutting of the first-year growth. Owing to different 

 weather conditions which prevailed at the time of cutting, and 

 which necessitated different methods of handling, the amount of 

 leaves lost in curing was not uniform; hence a strictly fair 

 comparison could not be made between the different cuttings. 

 The results are therefore reported together, and the average 

 given for the several lots. In order to draw accurate concJu- 

 sions between cuttings, the crop should either be fed green or 

 cured under uniform conditions. Owing to frequent weather 

 changes this is often not possible in New England.
