94 Tlie Lung Plague of Cattle. 



er's stable and tlie pestiferous system of peddling c<.wa 

 fi-om herd to herd and of placing infected cows for trial 

 in a number of herds successively. 



In such a city as New Tork it was impracticable to 

 stop the cow market ; but by this arrangement we can 

 control it so as to reduce its evils to the minimum. The 

 system as above sketched has only been perfected for a 

 short time, but already it has given the most encouraj,'- 

 ing results having almost completely extinguished the 

 plague in that city. The milkmen heartily approve it, 

 as they now receive their cattle with a guarantee ol 

 health, and by buying at the yards they have a better 

 choice and can make better terms than under the old 

 system of buying from the dealer's stable and peddler's 

 drove. Then, too, they find that the introduction of a 

 fresh cow is not the signal for a new appearance of dis- 

 ease, as was so commonly the case in times past. It 

 would be difficult, to-day, to impose upon a New Tork 

 milkman a cow that comes without General Patrick's 

 permit and the inspector's marks. Most dealers who 

 formerly kept their cows at the Union Stock-Yards like 

 the system, for a sale is now a bona fide sale and brings 

 the money in place of promises to be redeemed little by 

 little at uncertain intervals. Some grumble, but only 

 because they can no longer pursue their calling at the 

 expense of a constant propagation of disease. 



Disuse of Quarantine Notices. — In a locality controlled 

 as New York city now is, the posting of quarantine no- 

 bices on buildings is more injurious than beneficial. No 

 cows can enter the premises except with a permit on 

 which the destination is stated and none can leave except 

 for immediate slaughter. The object of the notice is 

 fully attained by these measures, and the notice on the 

 building without accomplishing any good, imperils the 

 sale of milk from the herd, and, in fear of this, the 

 owner is liable to hide the existence of disease. For
