animal food. The growth was over three times as rapid as under 

 another ration in which most of the protein was of vegetable 

 origin with enough skim-milk curd added to supply about one- 

 fourth of the total protein. 



In the general vigor and health of the chicks there was some 

 difference in favor of the animal food ration. This difference was 

 very pronounced with the ducklings. 



PRODUCTION OF FIELD CROrS. 



The experiments on Long Island in the use of commercial fer- 

 tilizers on potatoes have been continued with some enlargement. 

 Three acres of land are now in use on each of four farms. A fer- 

 tilizer experiment with onions was also carried on in 1898. 

 Twelve acres of land on the Station farm are now devoted to a 

 somewhat elaborate study of methods of maintaining fertility, and 

 although two years' results are already in hand, nothing will be 

 published for some time, perhaps not for several years.
