including many dairy herds of large cities, were quarantined 

 in whole or in part because of the foot-and-mouth disease. 

 To prevent contagion, there should be absolutely no 

 passing between diseased herds and other territory. Vis- 

 itors should stay away from affected farms; dogs and cats 

 should not be allowed to roam about; even birds such as 

 have the habit of alighting in barnyards may carry the 

 germs. The pasteurizing of milk renders it less dangerous, 

 and this precaution should never be neglected at times and 

 places where the foot-and-mouth disease prevails.
