From the Director . . . 



Research in an agricultural ex- 

 periment station is not conducted 

 exclusively for the benefit of fanners 

 hut is intended to he of value to all 

 people. For example, I would like to 

 call your atteiition particularly to 

 the articles appearing in this issue 

 on Warfarin and Newcastle disease. 

 Warfarin was discovered at the Uni- 

 versity of Wisconsin in a study to 

 determine the cause of hemorrhage 

 in cattle that had consumed sweet 

 clover. This research led not only to 

 the use of Warfarin as a poison for 

 rodeJits but also to the discovery of a 

 similar chemical in the treatment of 

 embolism in humans. 



Although our study of Newcastle 

 disease is directed toward the solution of problems related to the poultry in- 

 dustry, the fundamental information gained from this study may eventually 

 lead to the formulation of a cure for such important virus diseases as the 

 common cold and influenza. 



For the average person, the secondary benefits derived from agricidtural 

 research are, in many instances, of greater interest and more practical im- 

 portance than the primary information.
