Dr. "Wray remained at Cynthiana until June 22, or about three 

 months after the last affected animal was slaughtered, and no case 

 of this disease was discovered during that time. _ I have recently had 

 reliable reports from that vicinity, and I am satisfied that no case of 

 pleuro-pneumonia has occurred since the slaughter of the infected 

 cattle in March. 



This outbreak in Kentucky by itself indicates the great superiority 

 of a method which secures the prompt extirpation of the contagion 

 over any temporizing measures, the effect of which is to preserve in- 

 stead of to destroy it. As soon as pleuro-pneumonia was known to exist 

 in Kentucky the other States of the Union quarantined against Ken- 

 tucky cattle, and the enormous commerce in these animals was pros- 

 trated. The local quarantine measures were looked upon by the au- 

 thorities of other States as an insufficient guarantee of the safety of 

 cattle from Kentucky, and therefore no bovine animals were allowed 

 admittance from there except under rigid and burdensome restrictions. 

 These restrictions, maintamed for nearly two years, are estimated 

 to have caused a loss to the cattle-breeders of the State of from 

 $10,000,000 to $12,000,000; a loss which would have been entirely pre- 

 vented if there had beeii authority for this Department to cause the 

 prompt destruction of the infected herds when the plague was first 

 discovered. 



ILLINOIS. 



In September, 1886, pleuro-pneumonia was found by the State vet- 

 erinarian to exist among cattle in the city of Chicago and vicinity. 

 It was first discovered on the farm of John Carne, at Kidgeland, near 

 Austin, a station on the Chicago and Northwestern Railroad, 6 or 7 

 miles from Chicago. The diseased animal was killed September 12, 

 and the jMst mortem examination showed conclusively that it was 

 affected with lung-plague. This cow had been on the premises a long 

 time, but she had recently been exposed to an ailing cow that Mr. 

 Carne had taken for trial with the intention of purchasing. This sick 

 cow was brought on the place by Silas Palmer, a cow dealer, who had 

 pastured her for some time previous on tlie Harvey farm, near Hum- 

 boldt Park. It was represented to Mr. Carne that the cow was suf- 

 fering from bad treatment and would soon recover. After doctoring 

 it for two or three weeks with no success the dealer was notified that 

 it was not wanted, and he removed it. 



In an attempt to trace the contagion the Harvey farm was visited 

 by the State veterinarian September 15 and 16, and he found there 250 

 head of cattle, among which were 8 affected with pleuro-pneumonia. 

 These animals were at once quarantined. An investigation of the 

 history of the disease at this farm led to the conclusion that it had 

 been introduced by a herd of 38 cows brought there to pasture by a 

 milkman named Quinn, who had recently removed his animals from 

 the Phoenix Distillery stables. This led to an examination of the cat- 

 tle in the distillery stables, and to the discovery that many of them 

 were affected with pleuro-pneumonia. 



The Phoenix stables were quarantined September 10. They con- 

 tained 1,185 animals, of which 207 were Western steers and bulls 

 which had lieen placed there to fatten September 15 by Nelson Morris. 

 The remainder of the animals were milch cows, belonging to a number 

 of different owners. The stables of the Chicago and Empire Distil-
