cord too long, thus increasing the liability of its 

 becoming infected. These tumors continue to 

 grow, and in the worst cases attain the size of a 

 man's head. Cut down on a tumor the same as 

 in a simple case of castration. Separate the skin 

 from the tumor and then swallow up the cord with 

 the hands. Cut the cord ofif as high up as possible. 

 The wound may be healed by the use of any of the 

 common disinfectants. A teaspoonful of carbolic 

 acid in a quart of water may be used once daily 

 until the pigs are healed. Pigs should be kept in 

 a clean pen after the operation. 



WARBLES. — These are lumps in the skin of 

 cattle, caused by grubs or warbles. A simple treat- 

 ment is to cut the skin and squeeze out the grubs 

 where the lumps are noticed. If all the grubs are 

 killed in this way, there will be no mature flies to 

 cause trouble later on. See article on Bot Flies. 



WARTS. — The cause of these little tumors of the 

 skin is not definitely known. They occur on all 

 domestic animals, appearing most frequently on 

 horses and cattle. Pure acetic acid, dropped on 

 the wart until it is saturated and softened, de- 

 stroys in the early stages. Warts about which a 

 small cord may be tied are most easily treated in 

 that way. After they have sloughed off, apply a 

 little terchloride of antimony with a feather or cot- 

 ton. When the scab forms, remove it and apply 

 the chemical again. With a couple of applications 

 the spot will be lower than the surrounding skin. 

 Now use an ointment, made of 4 tablespoonfuls of 

 oxide of zinc and 8 tablespoonfuls of lard. Apply 

 this daily until the sore spot is healed. Sometimes 

 a form of warts suddenly appears on colts and 

 calves and scatter themselves about the lips, nose
