 received special attention. 



The main interest of our inquiry, however, consists in the partial 

 or entire substitution under otherwise corresponding circumstances 

 of dry corn fodder, or corn stover or corn ensilage, for English hay 

 as far as net cost of feed and quality and quantity of milk are con- 

 cerned. The results of former years are already on record, in our 

 respective annual reports ; they lead to the same conclusions. The 

 net cost of the daily feed during our late experiment has been stated 

 on preceding pages of this bulletin. The quality of the milk and 

 cream obtained on that occasion may be learned from the subsequent 

 tabular record. More details of a similar character are reserved 

 for our next annual report.
