 lence than by any other method, and the indemnity of the 

 owner in no niggardly spirit is a simple matter of justice 

 on the part of the nation toward the citizen. 



Measures for Extinction of a Prevailing Plague. It is 

 not within the province of this book to treat fully on the en- 

 tire subject of veterinary sanitary administration, yet it 

 seems desirable that the public at large should be made ac- 

 quainted with the leading principles that must guide such 

 administration. The measures will necessai-ily vary with 

 each animal plague, and to some extent according to the nat- 

 ure of the local animal industry, yet some general princi- 

 ples must dominate in all cases, and these may be stated un- 

 der separate headings. 



Setting aside the preliminary discovery of the plague in a 

 State or district toward which investigations must often be 

 made on the merest suspicion, in a counti-y where move- 

 ment is so free as with us, and in which the plague in ques- 

 tion already exists, we may note those fundamental meas- 

 m-es that look especially toward extinction. 



1st. The infected district must be proclaimed. 



2d. All movement of animals susceptible to the plague 

 in question must be temporarily stopped in the infected dis- 

 trict. 



3d. All mingling or contact of separate herds oi suscepti- 

 ble animals within said district must be put a stop to. 



4th. All exposure of susceptible animals on public high 

 ways or on unfenced pasturages must be vigorously inter- 

 dicted. 



5th. Insusceptible animals mingling with suspected herds 

 must be prohibited from passing into other herds of suscepti- 

 ble animals. 



6th. Attendants on suspected herds must be rigidly kept 

 from all other susceptible animals. Visitors except such as 

 attend oflScially must be excluded from all suspected herds.
