REPORT OF THE BUREAU OF A1STIMAL INDUSTRY. 33 



spread by these cattle that the Department offered to purchase and 

 slaughter without cost to the State all exposed animals which the 

 local authorities were unwilling to destroy at State expense. A fav- 

 orable reply was made to Ijhis proposition, and after much correspond- 

 ence with the special agent of the governor, who has charge of this 

 branch of the service in that State, an agreement adopting a modifi- 

 cation of these rules was decided upon. The chief modification of the 

 rules was that no herd should be slaughtered as affected with pleuro- 

 pneumonia until it had been examined and the diagnosis confirmed by 

 the State veterinarian, who should be paid for this service from the ap- 

 propriation of the Bureau. It was further agreed that the governor 

 would issue a proclamation placing all cattle in quarantine which 

 were on any premises situated within 8 miles of the city hall of Phil- 

 adelphia. 



The proclamation was issued to take effect upon April 9, 1888, and 

 at that time a force of men employed by the Bureau began work in- 

 specting, tagging, and registering all cattle in the specified district. 

 Post-mortem examinations were made on all carcasses of cattle which 

 had died and had been taken to rendering works, and of all cows 

 from this district which were slaughtered for food. With these reg- 

 ulations in force it becomes possible to locate the herds affected with 

 pleuro-pneumonia in the vicinity of Philadelphia, and to eradicate 

 the disease. The relations between the State authorities and the 

 officers of the Bureau have been harmonious, and all differences of 

 opinion in regard to diagnosis have been settled by the slaughter and 

 post-mortem examination of the affected animals. 



From January 1 to November 30, 1888, there were inspected in 

 Pennsylvania 5,291 herds, containing 72,565 head of cattle. Of this 

 number 18, 763 .were re-examined by deputies, in addition to the pro- 

 fessional inspections, and 51,820 were tagged with numbers and reg- 

 istered upon the books of the Bureau. 



There were 23 herds found affected with pleuro-pneumonia, and 

 these herds contained 260 animals, 49 of which were pronounced dis- 

 eased when the inspections were made. There were purchased for 

 slaughter 63 affected cattle, at a cost of $1,243.50, an average of 

 $19.73 per head ; also 131 exposed cattle at a cost of $3,167.50, an aver- 

 age of $24.18 per head. 



It was considered advisable to disinfect 117 stables, stock-yards, 

 or other premises ; and 13,157 post-mortem examinations were made 

 upon the carcasses of bovine animals, of which 72 were found dis- 

 eased with pleuro-pneumonia. 



The total expenses in Pennsylvania from January 1 to November 

 30, 1888, have been $37,978.23, of which $4,411 was paid for cattle 

 purchased for slaughter as either diseased or exposed. The remain- 

 der constitutes the expense for disinfection, inspection, tagging, reg- 

 istering, making post-mortem examinations, and maintaining that 

 close supervision of all the cattle in the infected district which is ab- 

 solutely essential for the complete success of the effort for the total 

 eradication of pleuro-pneumonia. 



It has been decided that the governor should issue a proclamation 

 removing the quarantine restrictions at Philadelphia, to take effect 

 December 15, 1888, and at that time the greater part of the force 

 stationed there by this Department will be withdrawn. There is 

 every reason to -believe that Pennsylvania is now entirely free from 

 this contagion, but it is deemed advisable to maintain a supervision 

 of the cattle in transit through Philadelphia, and also to watch the
