be  adhered  to  by  this  Board  in  dealing  with  this  question  and  I 
submit  the  same  for  your  consideration. 
1.  Tuberculin  supplied  free  of  charge  by  the  Bureau  of  Ani- 
mal Industry  will  only  be  furnished  to  veterinarians  in  the  em- 
ploy of  the  territorial  or  county  governments  or  to  veterinarians 
working  under  the  direct  supervision  of  territorial  or  county 
veterinarians. 
2.  No  animal  or  herd  will  be  tested  by  officers  of  this  Board 
and  with  federal  tuberculin  unless  the  owner  first  agrees  to  segre- 
gate or  dispose  of  all  reacting  animals  in  such  a way  that  their 
milk  is  forever  precluded  from  being  used  for  human  consump- 
tion, nor  to  be  fed  to  calves  or  pigs  or  used  for  the  manufacture 
of  butter,  cheese  or  other  dairy  products  without  having  previ- 
ously been  pasteurized ; all  reacting  male  animals  to  be  excluded 
from  breeding  purposes ; all  reacting  animals  to  be  plainly  branded 
on  both  sides  with  the  registered  brand  of  this  Board  which  con- 
sist of  a TV  connected  at  the  top,  the  same  to  be  first  advertised 
and  announced  to  indicate  that  an  animal  which  bears  the  said 
brand  has  been  officially  tested  and  found  to  be  suffering  from 
tuberculosis. 
The  disposition  of  reacting  animals  is  a problem  which 
has  made  the  eradication  of  tuberculosis  among  cattle 
very  difficult  wherever  it  has  been  attempted.  Various 
methods  have  been  employed  among  which  the  most 
successful  has  been  the  so-called  “Bang”  method  which 
is  used  principally  in  the  old  country  and  in  some  of  the 
eastern  states  as  New  York  and  Pennsylvania.  This  method  con- 
sists in  the  absolute  segregation  of  reacting  from  non-reacting 
animals  on  the  premises  of  the  owner,  but  requires  separate  barns, 
yards,  milk  houses  and  utensils  and,  on  large  estates,  of  separate 
attendants.  This  method,  however,  is  principally  resorted  to 
where  the  question  is  to  preserve  a highly  developed  strain  of 
blood  or  valuable  breeding  animals.  The  principal  feature  of  the 
method  consists  in  the  removal  of  all  calves  from  the  reacting 
division  immediately  after  birth  and  a systematic  testing  of  all 
non-reacting  animals,  at  least  once  a year.  The  method  is  ex- 
pensive only  as  far  as  its  installation  is  concerned,  but  does  away 
with  the  destruction  of  all  reacting  animals  except  those  suffer- 
ing from  tuberculosis  in  an  advanced  state. 
The  next  method  consists  in  the  destruction  of  all  reacting  ani- 
mals, the  same  being  sent  to  slaughter  houses  where  Federal 
meat  inspection  is  maintained,  and  the  carcasses  disposed  of  ac- 
cording to  the  judgment  of  the  meat  inspector  as  to  whether  fit 
for  human  consumption  or  not.  This  method  is  principally  em- 
ployed in  those  states  of  the  Union  which  pay  a compensation 
to  the  owner  in  proportion  to  the  loss  suffered  by  him. 
Either  of  the  methods  might  be  employed  here  or  a cooperative 
breeding  farm  for  reacting  animals  might  be  established  with  sup-
