 owner loses, unless the disease is found in the udder. 



In other words, the "Bang system" calls for the tuberculin 

 test upon all animals ; the destruction of all showing clinical 

 symptoms; the complete isolation of all reacting animals, in 

 separate bams ; separate attendants ; pasteurizing the milk ; 

 selling it for just what it is in competition with healthy milk, 

 usually only to creameries, to be made into butter; the sound 

 animals to be tested once in six months, and any reacting one? 

 to be placed with the diseased ones; the calves from diseased 

 animals used for the propagation of stock, to be immediately 

 taken away and raised on healthy cows or on pasteurized milk. 



Denmark pays for animals diseased in the udder; pays for 

 the tuberculin testing of all animals ; pays nothing for animals 

 that are diseased and destroyed unless the disease is in the 

 udder. 



In one experiment 245 cattle were tested and 82% reacted. 

 From this 82% calves were raised, and in four years only one 

 calf reacted. 



This was the best experiment he gave. In another experi- 

 ment it took eight years to bring the herd out with only 2 

 reacting animals. 



This herd consisted of 264 head and were tested semi-annu- 

 ally. So that the Bang system is as he says "a gradual purifi- 

 cation of an infected stock during the course of several years." 



The originally infected stock die off in their isolated quarters 

 and being isolated no infection comes from them. Prof. Bang 

 stated that they were not doing enough in his country and that 

 he wished they could do more. Even in Denmark, there has 

 been according to his own report, "a sad falling ofif." Accord- 

 ing to the report, out of 1,000,000 cattle, there were tested in the 

 year 1907. some 22,982 head and 2,252 reacted, which is 10%. 

 This number includes cattle under treatment. This would not 

 seem to be a very extensive business as compared with Maine, 

 as we have 300,000 cattle and during the same year we tested 

 nearly 25,000 head, yet this is nothing against the Bang method. 

 The government of Denmark appropriates 100,000 Krones, or 

 $25,000 of our money, yearly for a term of 5 years, and we 

 spent $32,000 during the year 1907. If their per cent of udder
