convinced that conditions have improved. All are unanimous in placing 

 their stamp of approval upon the work thus far conducted, and all hope 

 the work in connection with the problem of eradication may be carried 

 through to a successful finish. 



We believe that the results both of our scientific work and of its practical 

 application may be confidently depended upon and that examination will 

 convince even the most skeptical. Poultrymen who have suffered great 

 losses wiU be unanimous in supporting the views of workers in this De- 

 partment; i.e., that it is possible to rid Massachusetts for the most part 

 of this disease, and that a campaign should be organized against bacillary 

 white diarrhea infection. 



The problem of eradicating Bacterium pulloriwi infection involves 

 organization, clerical detail and a constant observation of the laws govern- 

 ing the study and progress of disease. It is a problem in practical pathol- 

 ogy, and can be solved only by the pathologist and poultryman co-operat- 

 ing. The methods of the laboratory play an important part in the 

 campaign. Therefore, intelligent, efficient and conscientious co-operation 

 of all concerned is essential for success. 



To efiiciently handle the situation the work of the campaign must be 

 centered in a strictly scientific atmosphere, since it requires pathological 

 organization, efficient laboratory analyses and record keeping based on 

 such knowledge. Therefore, if funds are provided, the Department of 

 Veterinary Science with its laboratory equipment already established 

 would be in a position to continue the work to help eliminate domestic 

 fowls in the State of Massachusetts carrying Bacterium puUorum infection, 

 which has been the cause of great mortalitj^ of j^oung cliicks.
