lisease should be undertaken on those lines applicable to con- 
agious diseases in general. When the disease is recognized 
n a stable, the affected animals should be promptly removed, 
nd the stable thoroughly disinfected, close watching being 
naintained for new cases. Thorough ventilation tends to les- 
en the virulence of the contagion. Public stables where the 
lisease exists should be thoroughly disinfected, and diseased 
nimals properly isolated, or the stable closed to transient 
nimals. Careful feeding on light laxative diet, with light 
york or exercise, taking especial care not to work the animal 
fter the development of the disease, will do much to modify 
he severity of the attack. Convalescents should not be al- 
bwed to mingle with unexposed animals until after five or 
ix weeks, and not even then should traces of the disease re¬ 
gain manifest. Animals known to have been recentlv ex¬ 
posed to the disease should not be allowed in close contact 
dth other horses at fairs, horse shows, race meetings, and 
t other places where large numbers of horses congregate. 
Then the disease breaks out at such places, the affected ani- 
lals should be isolated as carefully as possible, and the ex- 
osed animals closely watched. Its control by protective in- 
culation has been attempted, but so far without being ren- 
ered practicable, although, as would be expected, a degree 
;f immunity has apparently been attained.
