STATISTICS RELATING TO ANIMALS ON FARMS 273 



cows have been made on the basis of the number reacting 

 to the tuberculin tests. These estimates indicate that a 

 larger percentage, possibly 25 per cent., of the dairy 

 cows in the country will be slaughtered in the campaign 

 of exterminating this threatening disease. The near 

 future for this reason will see a still greater increase 

 in the value of sound cows.
