and various organs of pigs is being continued. We Ijave 

 collected quite a quantity of data, have repeated feed- 

 ing tests and liave made a large number of blood examina- 

 tions and also examinations of sections of various organs, 

 such as the liver, spleen, kidneys, heart, and , lungs. We 

 hav^ also made some observations, on the effects, of cotton, 

 seed. meal on the health and condition of horses and mules. 

 An experiment is now planned for carrying out a feeding 

 test in which cotton seed meal w.ill be used a's the chief or 

 only ingredient .of the ration. It has been obseryed.for some 

 time that hogs and pigs which are fed on peanuts become 

 affected. Tliis has-been investigated and experimental tests 

 will be made. ,. . . 



The sanitary conditions of, farms in their relation to the 

 health of the people and animals on the farm have com- 

 manded our attention. It has been especially noted that 

 careless methods in the disposal of carcasses of dead ani- 

 mals on the farm are responsible for the extension and 

 spread of a number of animal diseases. It should be espe- 

 cially noted that buzzards are carriers of infectious mate- 

 rials from farm to farm, and are consequently great factors 

 in the transmission of infectious diseases.
