SUMMARY. 



In Experiment I (Alfalfa, Second Cutting) each day's 

 feces were analyzed separately, but no great variation in com- 

 position was noted. 



In Experiment II (Alfalfa, Second Cutting) four dif- 

 ferent composite samples of the hay were made up and an- 

 alyzed with the following results : 



Average 6.25 



8.12 



1.48 



33.22 



14.10 



36.83 



This shows the necessity of extreme care in sampling, if 

 results obtained are to be relied upon, as hay from the same 

 plot of ground varies in composition. 



The average composition of the alfalfa used in the ex- 

 periments given in this bulletin are as follows :
