(b) Water. When possible to provide otherwise reacting 
cattle should not be watered at running streams which after- 
wards flow directly through fields occupied by sound cattle. The 
water from drinking trough used by infected animals should not 
be allowed to flow into stables, fields or yards occupied by sound 
animals. 
(c) StasLe. Reacting cattle should be kept in barns or 
stable entirely separate from the ones occupied by the sound ani- 
mals. 
2. Calves of the reacting cows should be removed from their 
dams immediately after birth. Milk fed these calves must be 
from healthy cows, otherwise, it must be properly pasteurized. 
These calves should not come in contact in any way with the 
reacting animals. : 
3. The non-reacting animals should be tested with tuberculin 
in six months, and when reactors are found at the first six 
months, or any subsequent test, the others should be retested 
not more than six months later. When there are no more re- 
actors at the six months’ test, annual tests should thereafter be 
made. All reacting animals should at once be separated from 
the new herd and the stables which they have occupied thor- 
oughly disinfected. 
4. The milk of the reacting animals may be pasteurized and 
used. 
5. Any reacting animal which develops clinical symptoms of 
tuberculosis should be promptly slaughtered. 
6. An animal that has once reacted to tuberculin should un- 
der no circumstances be placed in the sound herd. 
7. As soon as the sound herd had become well established, 
infected animals should be slaughtered, under proper inspection. 
GROUP III. 
Herds that come within this group should be dealt with either 
as in Group II, where the herd is separated, or as in Group 
I, where all of the animals are considered as suspicious and an 
entirely new herd developed from the offspring. 
GENERAL PRECAUTIONS, 
In ALL cases animals that show clinical evidence of the disease
