accomplished by sawing or clipping the horns close to the 

 head. Unless this skin is removed the horns will grow 

 again and produce what are known as scurs. 



The substance usually applied after removal of the 

 horns is pine tar. This helps to keep away flies and prob- 

 ably assists in checking the bleeding. If bleeding persists, 

 it can be stopped by passing a string around the horn- 

 stubs and twisting tightly over the poll. This string should 

 be removed as soon as danger of bleeding ceases, or in 

 about 12 hours. To avoid any trouble from flies it is best 

 to dehorn during the late fall, winter, or early spring. Ex- 

 periments indicate that the milk flow of dairy cows is not 

 seriously affected by dehorning.
