84 THE LUNG PLAGUE OF CATTLE. 



but only as beef. Abattoirs will therefore be a necessary adjunct to all 

 such markets, and all the great stock-yards in the eastern cities are al- 

 ready provided with such. In such abattoirs the butchers may be 

 allowed to kill and dress their cattle for a reasonable consideration, 

 which should be prescribed and uniform. The beef may be removed to 

 any requisite distance as quarters, and at no very greatly increased 

 trouble or cost. 



The objection to letting cattle leave such markets alive is that it is 

 impossible to control the traffic, and a certain number are usually kept 

 for a week or more awaiting slaughter in contact with local store cattle 

 or in dangerous proximity to them ; further, it is no uncommon matter 

 for individual animals out of a herd from the stock-yards to be smuggled 

 into city cow stables in place of going direct to the slaughter-house. 

 Coming as they do from a common market where the sick and healthy 

 meet, they are constantly liable to carry infection along with them. 



The plan proposed may be held to represent the foreign animals 7 

 wharves in England, and is a legitimate and necessary means of pre- 

 venting any further diffusion of infection. By its means the stock-yards 

 at New York and Jersey City can supply all the surrounding cities with 

 fresh beef, while those who object to sending their cattle there from 

 healthy States, and those who wish to remove their cattle from the 

 yards for slaughter at their ow,n abattoirs have before them the bonded 

 cattle market offering every facility for such a course. 



POWER TO PROHIBIT ALL MOVEMENT OF CATTLE EXCEPT UNDER 



LICENSE. 



This is absolutely essential to success in dealing with this disease any- 

 ' where, but is especially so in the cities for reasons that are fully set forth 

 in an earlier part of this report. ( See under heading l i Why the lung plague 

 lias extended south onlyf page 22). 



POWER TO ENTER ALL PREMISES OCCUPIED BY CATTLE, AND TO IN- 

 SPECT ALL HERDS IN THE SUSPECTED DISTRICTS. 



The want of this is apparent without elucidation. 



POWER AND OBLIGATION TO SLAUGHTER ALL CATTLE SUFFERING 

 FROM LUNG PLAGUE, ACUTE OR CHRONIC. 



This is a sine qua non. So long as the sick live the virus is being mul- 

 tiplied. With their death and deep burial or disinfection, the increase 

 is arrested. 



POWEJt TO SLAUGHTER THE WHOLE SUSPECTED HERD WHEN FOUND 



EXPEDIENT. 



It is often of the highest imj>ortance that this power should be pos- 

 sessed and exercised. Cattle that have been exposed to infection but 

 are not yet sick may be so placed that in case of their sickening they 

 will infect other animals, and to obviate great losses it is often impera- 

 tive that such animals should be killed. 



A most important and successful exercise of this power occurred on 

 Montauk, L. I.,New York, where the slaughter of twenty calves saved 

 a herd of twelve hundred cattle of all ages.
