ises to separate the healthy from the reacting animals. It may be 

 of interest to notice what is demanded in this respect. The healthy 

 animals must be placed in a separate room. This ma}' be obtained 

 by placing in the stable a wooden partition reaching from floor to 

 ceiling, like that described on page 23 in Thurebylille. It has even 

 been necessary to permit a door to be placed in this wall to accommo- 

 date the fodder passage or the dung passage or even both. Under 

 such circumstances a complete exclusion is very difficult to maintain, 

 but the owner is always told that, for his interest, the separation 

 must be as complete as possible. If a door be placed in the wall it 

 must always be carefully closed after being used. 



With reference to the stable-workers, the owner is always told that 

 it is far better to have entirely different persons for the two divisions ; 

 but it is verv difficult to attain the ideal. On large farms, a near 

 approach is made, but the desirable is seldom reached. I believe, 

 however, that the danger of infection through persons is not very 

 great. It can doubtless be very much lessened by following the 

 simple rule to visit first the healthy division, and to wear there 

 separate shoes and outside garments. 



In Denmark the rules observed in su])duiug tuberculosis are not 

 guarded by the police. The state wishes simply to lend a helping 

 hand to the farmers in their struggle for freedom from the evil. The 

 chief task, therefore, is to give the owners a correct understanding 

 of the nature of tuberculosis and to explain the principal means of 

 contagion. When the farmer correctl}' understands these matters he 

 will succeed in the struggle, although local conditions may not favor 

 a desirable separation. While I have not insisted very strongly on 

 the last requirement I have done so knowingly and because I see 

 more chance for success when the farniers begin^their struggle ho})e- 

 fully. After having attained a few good results, they will doubtless 

 be more willing to make larger sacrifice in order to win greater 

 success. 



The larger majority of the tuberculin tests accomplished in Den- 

 mark have only Ijeen undertaken tluring the last year. It is there- 

 fore too early to look for great success. However, in many places 

 such has most certainly been attained. Many small herds have, 

 after the removal of the reacting animals, been entirely freed from 

 the disease. Where two divisions are kept on the same farm, the 

 test made after the first year has shown, as a rule, a decided increase
