REPOET OF THE SECEETARY OF AGRICULTURE. 15 



calf showed fever, drooling, and mouth erosions ; but the case was not 

 diagnosed as foot-and-mouth disease because of the absence of foot 

 lesions. Neither these visits, these opinions, nor the results of the 

 inoculation were made known to the department in Washington until 

 October 10. 



The pathologist connected with the office of the State veterinarian 

 of Indiana, on October 12, received specimens from infected ani- 

 mals and made cultures which upon microscopic examination dis- 

 closed the necrosis bacillus. The presence of this organism was 

 considered sufficient to indicate that the lesions were those of necrotic 

 stomatitis. 



On October 5 the State veterinarian of Michigan, the president of 

 the Live Stock Sanitary Commission, and the inspector in charge of the 

 office of the Bureau of Animal Industry at Detroit went to Berrien 

 County to make another examination. A letter from the inspector, 

 in which he included no diagnosis but described in detail certain 

 symptoms pointing to the possibility of foot-and-mouth disease, was 

 received by the chief of the bureau in Washington Saturday after- 

 noon, October 10. This was the first information to reach him giv- 

 ing ground for suspicion that foot-and-mouth disease might be 

 present. The inspector at Detroit had not had any experience with 

 this malady and for that reason did not attempt a diagnosis. An 

 expert was sent from Washington to Michigan on the first train 

 after the letter was received, while calves were inoculated at the bu- 

 reau's experiment station near Washington. In addition to physical 

 examination, calves also were inoculated by the expert on the ground. 



Spread of infection and steps for eradication. — Immediately after 

 the discovery of the true nature of the disease a force of inspectors 

 was dispatched to the infected locality. A thorough canvass dis- 

 closed, up to October 17, 39 infected herds in southern Michigan and 

 7 in northern Indiana. An order, effective October 19, was issued, 

 placing under quarantine the counties of Berrien and Cass, in Michi- 

 gan, and St. Joseph and Laporte, in Indiana. 



The infection seems to have been carried in milk to the cream- 

 eries at Buchanan, Mich. The skimmed milk was fed to hogs and 

 the disease was communicated to them. A carload of the hogs, 

 before these facts were known, was shipped to Chicago and doubtless 

 carried the infection to the Union Stock Yards there. From that 

 point it was spread by shipments of live stock to various parts of the
