Third-year growth. 



2 First-year growth. 



Unfortunately an exact record of the weather conditions 

 during- the curing process of the several lots Vv'^as not kept. It 

 would appear that the first cutting of the third year groiuth 

 was cured without the loss of a great deal of leafy matter. 

 This is shown by the relatively low fiber percentage and the 

 high digestibility. The second cutting of the third year growth 

 evidently lost a considerable portion of its leaves, as indicated 

 by its high fiber percentage and lessened digestibility. The 

 first cutting of the first year growth also must have lost an ex- 

 cess of leaves, as it also shows excessive fiber and low digestion 

 coefficients. It is possible that the markings of the first cut- 

 ting third-year growth and the first cutting first-year growth 

 were reversed, although we have not the slightest evidence to 

 that effect. 



While the coefficients obtained vary considerablv the aver- 

 age is about the same as the average for all trials, except that 

 the coefficient for fat is somewhat lower. It is believed that 

 the average coefficients obtained in our several trials show 

 fairly the digestibility of eastern-grown alfalfa under the ad- 

 verse conditions due to the loss of leaves in the process of 

 curing.
