PENNSYLVANIA. 



October 3 and 4 I visited Chester County, Pennsylvania, in company 

 -with Mr. T. J. Edge, special agent of the governor, and Dr. Bridge, State 

 Veterinarian. On the farm of W. P, Thomas I witnessed the slaughter 

 of 3 cows, and on the farm of J. H. Garret I saw 5 others killed, 

 these having been condemned by the State authorities as affected with 

 contagious pleuro pneumonia. The autopsies revealed the existence of 

 a \ ry similar condition in each of the animals. In most cases a whole 

 lung was hepatized and firmly attached to the diaphragm and ribs. In 

 several of the animals both lungs were affected. The pleural cavity 

 contained large quantities of straw-eolored effusion, and the connective 

 tissue of the iungs was excessively distended with exudation of a simi- 

 lar liquid. The inflammation was very plainly of a progressive char- 

 acter, and the marbling of the lung was as distinct as in any cases I have 

 ever seen. 



The disease was introduced into this section by a car-load of 14 cows 

 brought by John Xoble from Baltimore. Where these cows were orig- 

 inally infected is a contested point between the authorities of Penn- 

 sylvania and those of Maryland ; but there is no reason to doubt that 

 the outbreak near West Chester was caused by this lot of animals. 



These cows were sold as follows : July 19, to W. H. Shepherd, 1 j July 

 2G, to W. P. Thomas, 3; July 20, to H. Euches, 4; July 27, to J. H. 

 Garret, 2 ; August 1, to J. Kelly, 2 ; not traced .at time of report, 2. 



Mr. Shepherd's cow was found sick with symptoms of pleuro-pneu- 

 monia September 8, and slaughtered by the State authorities. The 

 autopsy revealed the characteristic lesions of lung plague. September 

 13 a cow was found affected with the same disease and slaughtered on 

 Mr. Garret's farm. September 20 it was necessary to slaughter one of 

 Mr. Thomas' cows. October 1 it was found that two cows had already 

 died on Mr. Euches' farm, and that six others were sick. 



According to information received from Dr. Bridge, October 23, 1884, 

 the number of cattle exposed and slaughtered on account of sickness 

 was as follows :
