JERSEY CATTLE AND PLEURO PNEUMONIA. 389 



Prof. Grange : Hardly. It resembles Texas fever in some respects and in 

 a given case without knowing the history of it I would hesitate about pro- 

 nouncing an opinion. Texas fever does not affect the lungs. 



Prof. Willits: I will say a word or two of my visit with Prof. Grange to 

 Chicago to see their management of the difllculty. You know Sheridan says 

 the only good Indian is a dead Indian, and so we say that the only good 

 pleuro pneumonia patient is a dead one. There are now before Congress lawa 

 for the settlement of this matter, but the question of jurisdiction and States* 

 rights is making trouble, and there seems to be doubt whether an efficient 

 law will be adopted. 



Prof. Grange : I saw 140 animals slaughtered in Chicago, all grade Short 

 Horns; one of them, the owner said, seemed to have had the disease before 

 and to have recovered. On killing it a cyst was found in the lung which was 

 liable at any time to break out again and spread the disease among fresh 

 animals. So there is no safety in any case that has once had or been exposed 

 to the disease. 



Question : How about disinfection of such animals? 



Prof. Grange: I do not know how it could be done to any purpose. In 

 the case of the cow mentioned I could not have told from an examination, 

 duriuj^ life, that she had pleuro pneumonia, though I might have been able 

 to s ly she had some lung difficulty. 



Question: Is there no cure? 



Prof. Grange: One of the greatest dangers is from the rases of apparently 

 complete recovery. Cysts still exist in the lungs ready to break forth on 

 provocation. The only thing to do in such cases is killing the affected ani- 

 mals and all others that have been exposed. Cattle are not subject to glanders^ 

 Cattle with pleuro-pneumonia generally do not stand up. With any lung^ 

 troubles cattle lie down and horses stand up. A horse under such cases has^ 

 to stand up to breath, while cattle with lung troubles breathe better lying 

 down. 



Mr. Dean: The question is asked as to manner of communication. A 

 friend in Peoria sold an animal from his farm that had spent a single night 

 in the same stable with a cow which afterwards gave evidence of plenro-pneu- 

 monia, and this animal from that one night's occupancy of the same stable 

 wiili a cow, which at the time had shown no illness, took the disease and 

 carried it to Missouri. In Quebec, in order to stamp out an outbreak, they 

 killed all exposed animals, and burned all the buildings, the clothes of the 

 men connected with the operations, and even the top eighteen inches of the- 

 soil, and yet it broke out again afterwards. 



President Willits: In these Chicago slaughterings they judged of the con- 

 'dition of the carcass by feeling of the lungs. If it v/as like liver in feeling, 

 the animal was affected. Some times there would be but slight traces — the 

 mere beginnings. There is no h'^lf way business in the matter possible^ 

 Congress is quarreling over the question of voting $1,000,000 to stamp this 

 thing out. They might better give 810,000,000 than to have it spread. 



Prof. Grange: As to eating the meat of affected animals. It is ordinarily 

 not dangerous unless in the acuter cases and in the later stages of the dis- 

 ease, and there have been no case^ of illness among human beingfs traceable 

 to the use of such affected meat. Eighteen thousand people in France were 

 ftd on meat from diseased animals (pleuro-pneumonia) and no ill effect 

 resulted. In the Chicago quarantine, of thirty-two animals slaughtered, 

 thirteen were affected and but two were condemned for food.
