DISPOSAL OF REACTORS. 
The disposal of reactors depends largely upon the State laws and 
live-stock regulations of the State in which the herd belongs. If the

THE ACCREDITED-HERD PLAN—EVERY CATTLE OWNER 
ELIGIBLE. 
A tuberculosis-free accredited herd is one which 
has been tuberculin tested by the subcutaneous 
method or any other approved method under the 
supervision of the Bureau of Animal Industry, 
or of a regularly employed veterinary inspector of 
the State in which cooperative tuberculosis eradi¬ 
cation is being conducted. 
It is a herd in which no animal affected with tuber¬ 
culosis has been found upon two annual or three 
semiannual tests, made as described, and by 
physical examination. 
Owners of tuberculosis-free herds receive a cer¬ 
tificate issued by the bureau and the State live¬ 
stock sanitary authorities. The certificate is good 
for one year from the date of the test, unless re¬ 
voked at an earlier date.
