 of average ensilage: 



PROBLEMS. 



1. From the above table calculate the per cent of water in each of 

 the crops named. 



2. Which of the feeds named in the foregoing table, has the widest 

 and which has the narrowest nutritive ratio? Which comes nearest being 

 a balanced ration for cows? 



Silo Construction. 



The construction and use of the silo has become in recent 

 years one of the most important additions to the science of 

 agriculture. 



The importance of the silo to our agricultural interests may
