should be promptly eliminated. They should be destroyed if 
the disease is evidently far advanced, if not, they may be 
slaughtered for food under proper inspection. 
All milk from tuberculous cows that is used for food pur- 
poses should be thoroughly pasteurized. ‘This means that it 
must be heated sufficiently to kill or to render harmless, any 
tubercle bacilli that may be present in it. For this, it is neces- 
sary to heat the milk for twenty minutes at 149° F. or for five 
minutes at 176° F. It is important that pails or other utensils 
used in carrying the unpasteurized milk should not be used, un- 
less previously sterilized, for storing the milk after it is pasteur- 
ized. 
When diseased animals are found, the stables from which 
they are taken should be thoroughly cleansed and disinfected. 
To accomplish this, all litter should be removed; floors, walls 
and ceilings carefully swept and the floors together with mangers 
and gutters, thoroughly scrubbed with soap and water. Thor- 
ough cleaning before the application of the disinfectant, can- 
not be too strongly emphasized. After cleansing, the disinfect- 
ant should be applied. A five per cent (5%) solution of carbolic 
acid, a I-1,000 solution of corrosive sublimate or a four per cent 
(4%) solution of sulphuric acid may be used. 
When the stable can be tightly closed, formaldehyde gas prop- 
erly used is reliable and satisfactory. 
If tuberculous cattle have been kept in a small yard the litter 
should be removed, the surface plowed and the fencing and other 
fixtures thoroughly cleansed and disinfected
