ducing germs will be in the dirt and manure of the stable. 

 If the stable is thorough^ cleaned most of the bacteria 

 will have been removed. 



All loose woodwork, especially box mangers, should be 

 removed. The walls, ceilings, and floors should be mois- 

 tened by spraying with a solution of corrosive sublimate 

 so as to prevent dust in the subsequent operations. The 

 loose material should all be removed ; the walls and floors 

 scraped until all dried manure and dirt is removed and 

 the bare wood or concrete exposed. All the material re- 

 moved should be burned, not thrown into the yard with 

 the cattle. The stable should now receive a good coat of 

 whitewash applied with a spray pump so .that it will 

 penetrate all cracks. Both walls and ceilings should be 

 treated, and the floors sprinkled with the dry water-slaked 

 lime. The mangers should be, scrubbed with a hot solu- 

 tion of lye, or a 5 per cent solution of carbolic acid. The 

 actual process of disinfection should be supplemented by 

 making provision for abundant , light and air. A half- 

 hearted job of disinfection is worse than none at all, since 

 it gives a fancied security, but little real security against 

 a re-occurrence of the disease. 



The disinfection of x yards is difficult. It can only be 

 attempted. The sprinkling of a liberal amount of dry 

 water-slaked lime is the best that can be done. The dis- 

 infection of fields is impossible. Small areas may be 

 limed or burned over. Neither of these methods is likely 

 to be effective in the case of spore-forming bactria. All 

 other forms will soon die without the addition of any 

 disinfectant.
