and renovation of all infected barns is imperative and good drain- 

 age, light and ventilation should be secured. 



Where these conditions cannot be obtained it would in many 

 cases be more economical and satisfactory to build new stables, 

 always observing the recommendations suggested for healthy herds.

In a bulletin lately published in the United States Bureau of 

 Animal Industry, the following methods of disinfection are recom- 

 mended : 



(a) Corrosive sublimate (mecuric chloride,) one ounce in about 

 eight gallons of water (one-tenth per cent.) The water should be 

 kept in wooden tubs or barrels and the sublimate added to it. The 

 whole must be allowed to stand for twenty-four hours, so as to give 

 the sublimate an opportunity to become entirely dissolved. Since 

 this solution is poisonous it should be kept covered up and well 

 guarded. It may be applied with a broom or mop and used freely 

 in all parts of the stable. Since it loses its virtue in proportion to 

 the amount of dirt present, all manure and other dirt should be first 

 removed and the stables well cleaned before applying the disinfec- 

 tant. After it has been applied the stable should be kept vacant 

 as long as possible. Before the animals are allowed to return it is 

 best to flush those parts which the animals may reach with their 

 tongues to remove any remaining poison.
