 Attention is directed to the large amount of work which has l)een done by the 

 experiment stations, aside from that carried on in coojjeration with the nutri-

 of the work are cited, particularly of studies pertaining to production and 

 distribution of food, improvement in yield and quality of cereals, improvement 

 in character of dairy products, food jireservation and preparation, and food 

 adulteration.
