DISEASES AND TREATMENT OF THE HORSE 243 



Treatment. — Do not attempt treatment of these tumors 

 until such time as they interfere with the usefulness of the 

 horse. Should treatment be advisable they may be cut off 

 with a. sharp knife, after which apply Monsell's solution of 

 iron to the spot with a feather to stop bleeding. They may be 

 treated with a cord as outlined in section 7, or with a ecra- 

 seur and afterward dealt with as an ordinary wound by bath- 

 ing twice a day with lukewarm water and applying, after 

 each bath, the white lotion. 



9. Mange. 



Mange is an insect para- 

 site that burrows into the 

 outer and nervous coating 

 of the skin, Fig. 31. It mul- 

 tiplies in enormous num- 

 bers and causes almost un- 

 bearable irritation. 



Causes. — Mange gener 

 ally originates with horses 

 that have long, dirty hair 

 and that are in poor con- 

 dition. Other horses ex- 

 posed to it may become af- 

 fected also, as the germ is 

 easily communicated by a 

 change of harness, coming 

 in contact with fences or 

 trees against which affect- 

 ed animals have been rub- 

 bing, the groom's clothes, 

 standing in the same stable 

 with others affected, and 

 so on. When mange is 

 suspected it is therefore 

 necessary to exercise the 

 greatest precaution to pre- 

 vent its spreading.
