DISEASES AND TREATMENT OF THE HORSE

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:. j.. ^ ,. .
