was burned. Holes where carcasses had been buried were partly 

 uncovered and filled with lime. Later Dr. Miller had the barn 

 disinfected with a strong solution of corrosive sublimate, of 1-1000 

 strength. By June 1st, the place was thoroughly disinfected, in- 

 cluding yard and grove in which dead animals had been buried, 

 where fifty barrels of lime had been used. The owner had then only 

 one horse left. He was advised to get a couple of cows and some 

 chickens, but to keep them out of the barn. One horse purchased 

 was placed in the orchard and died within six days. Further dis- 

 infection, including that of grain, was recommended. Dr. Miller 

 later authorized Mr. Kawson to purchase a vaccinated horse near 

 Kingsley. This "immune" lived seven days, dying very suddenly. 

 Slides made from the blood of this animal were found to contain 

 positive evidence of the disease. 



An outbreak of disease appeared about eight miles from the Raw- 

 son farm, and on examination of the blood, the disease was found to 

 be anthrax. 



In February this year, Peter Miller of near Remsen, lost six 

 cows from anthrax. These animals had been vaccinated the preced- 

 ing summer by a veterinarian from Le Mars. Potency of vaccine 

 is open to cpiestion. The trouble arose from feeding animals hay 

 from a meadow overflowed by a creek from infected premises. 



During the present summer an outbreak of anthrax occurred 

 near Mediapolis, Des Moines county. Twelve head had died when 

 this department was notified and we immediately quarantined the 

 premises. In all more than twenty head died. The infection in the 

 locality was confined to the premises of Edward McDonald, except 

 one case of human infection, that of Dr. H. M. Griffin, of Morning 

 Sun, whose arm was in bad condition. It was thought for a time 

 that it would be necessary to amputate the arm. However, he re- 

 covered without this drastic treatment. A son of McDonald's also 

 was infected. The seat of his infection was on the cheek. Prompt 

 measures were adopted for the control of this outbreak, after our 

 department had been called upon, and the work of veterinarians 

 in charge was very efficient and creditable. 



In May a call for vaccine was received from a farmer near Kings- 

 ley, who reported the death of two heifers near his place from an- 

 thrax. 



Owing to the tenacious nature of this disease its ultimate eradica- 

 tion from any locality is a matter of considerable time and pains.
