28 The Diseases of Animals 
YARDS AND CORRALS 
Yards and corrals in which animals have been con- 
fined for feeding or other purposes should be thoroughly 
renovated at least once a year, preferably in the spring. 
All manure, litter and rubbish should be removed, and 
puddles should be drained or filled. If any loose earth 
remains it should be carried away; but if this is not 
possible it can be stirred several times by means of a 
harrow or hoe, to allow the sun free aecess to it. If 
any sheds exist, they should be thoroughly cleaned and a 
eoat of whitewash or other disinfectant applied. Allow-

the summer is an excellent method of disinfecting. 
Weeds should not be allowed to grow in the yard.

healthy animals of those suffering from a contagious 
or infections disease. Whenever there is suspicion of 
a contagious disease the animals should be quarantined 
until the nature of the disease is known. Healthy 
animals should be removed from those that are sus-

have been confined. This is better than to remove the 
sick animals from the healthy, leaving the latter in 
infected quarters or on ground that may have hecome 
infected from the excretions of the sick animals. 
Care should further be taken that the healthy ani- 
mals are not exposed by means of infected food, water-
