22 EEPOBT OF THE BUREAU OF ANIMAL INDUSTRY. 



No information has since been obtained which would lead to 

 the conclusion that the contagion of pleuro-pneumonia exists in 

 any part of the country west of the Alleghany Mountains. There 

 is, consequently, good reason to believe that it is now confined to 

 the Atlantic sea-board, and with every month that elapses without 

 hearing from it elsewhere this conclusion is strengthened. With 

 the quarantine restrictions now in force in the infected districts 

 there is but little danger of the plague again finding its way to the 

 West, and with the continual repression and diminution of it at all 

 points this danger, small as it is, is constantly becoming less. 



During the whole period required for the eradication of pleuro- 

 pneumonia from Chicago and vicinity, being from October,, 188G, to 

 April, 1888, inclusive, it was found necessary to slaughter and pay 

 for 176 affected and 999 exposed cattle. The total disbursements 

 were as follows: For salaries, $52,170.31, for traveling expenses, 

 $3,819.29; for miscellaneous expenses, $4,126.61; for affected cattle, 

 $3,260.80; for exposed cattle, $16,561.64. The entire disbursements 

 amounted to $79,938.65. 



WORK IN MARYLAND, 



Baltimore County, Md., has long been acknowledged to* be one of 

 the worst infected localities in the United States. At the beginning 

 of the work, the plague was very prevalent there, affecting nearly 

 every herd in Baltimore and vicinity and extending for a considerable 

 distance into the country. The contagion had existed in the stables 

 and pastures there for so long a time that they were saturated with 

 it, and in many cases it was extremely difficult to secure their thorough 

 disinfection. The work there has, consequently, been as difficult as 

 it is possible for such work to be. Pleuro-pneumonia was also found 

 to exist in the counties of Anne Arundel, Carroll, Howard, and Prince 

 George's, in the same State. The affected herds in all these counties, 

 with the exception of Baltimore, were immediately slaughtered, and 

 the plague was at once eradicated. 



In city districts it is much more difficult to discover affected herds. 

 The owners are often ignorant, with no knowledge of the law, or 

 having such knowledge they conceal the disease. It is therefore only 

 by constant watching and thorough supervision of the movement of 

 animals that the diseased herds are discovered. Until November 10, 

 1887, the State live-stock sanitary board were unwilling to quaran- 

 tine all herds in Baltimore and require that no cattle should be moved 

 from one premises to another or allowed upon any vacant lot or high- 

 way without a permit. Their reasons for not making such an order 

 were, first, that they thought the disease could be eradicated without 

 these stringent regulations; and, secondly, they doubted their ability 

 to enforce it. 



An order was issued, however, which took effect November 10, 

 quarantining all bovine animals within 6 miles of the city hall of 

 Baltimore, and prohibiting any movement of cattle within this dis- 

 trict without a permit. The order is as follows: 



SPECIAL QUARANTINE REGULATIONS, 



Whereas the disease known as contagious pleuro-pneumonia now exists as an epi- 

 zootic among 'cattle in the city of Baltimore and portions of the county of Baltimore, 

 in the State of Maryland: 



jTherefore, in order to prevent the further spread of said contagion, I, Robert Ward, 

 chief veterinary inspector of Maryland, and the State live-stock sanitary board, by
