for a considerably longer period, until all signs of a discharge 

 disappear. 



(4). -The stable used for the isolated animals should be kept 

 thoroughly disinfected, care being taken to spray with a solution 

 of corrosive sublimate in water, 2 per cent solution, every day or 

 two, the floor and partitions until all discharge stops. 



(5). Do not breed affect&d cattle until absolutely certain that all 

 danger of infection has disappeared.

DEHORNING DAIRY cows is becoming more common and is, under 

 most conditions, quite the best practice. A good plan is to dehorn 

 as calves. This can be done by burning the horn buttons with 

 caustic potash or concentrated lye, when the calves are about ten

 into contact with the hands. Sufficient moisture should be used to
