204 AN AGRICULTURAL WAR PROBLEM 



nutrition of farm animals have been worked out! 

 on a basis which is as essentially scientific as that 

 which underlies the practice of medicine or en-< 

 gineering. Work is in progress which will rapidly 

 bring these principles into more direct practical 

 touch with British conditions. The exigencies of 

 the war have compelled even the most conservative 

 of farmers to recognize how directly scientific 

 knowledge can help them in buying and using the 

 cheaper foods on the market. It remains for those 

 of us who are responsible for the scientific side of 

 the subject to extend our knowledge and our teach- 

 ing, or we may lose the opportunity thus afforded 

 of influencing stock-keepers in the direction of 

 economy in production.
