104 ANNUAL REPGRT OF THE Off. DoC. 



tested with the result that sixty were found to be tubercular. There 

 was absoluiely no leasou to siisijcct that anything ailed this herd 

 until after the introduction of a young bull from a New York State 

 herd in which there is considerable tuberculosis. This bull died 

 when he was three years old, of a lingering, wasting disease that was 

 accompanied by coughing. The deaths from tuberculosis in this 

 herd have not been numerous, and probably for the reason that the 

 owner makes a business of selling cows, marketing each one as soon 

 as possible after she is developed. But there is reason to pity their 

 purchasers. 



''I shall not occupy your time by citing more illustrations of 

 the ways by which tuberculosis is spread nor of the losses to cattle 

 owners. It would be easy to till a long paper with accounts of in- 

 stances wherein tuberculosis has ruined herds and their owners, or 

 wherein, to avoid ruin, men have sold infected herds and have scat- 

 tered disease and ruin widely. 



"In this country, there is less tuberculosis than abroad, because the 

 country is younger and the disease has not had time to spread — to 

 soak into the vitals of the cattle industry. In the older parts of the 

 United States, there are localities where the prevalence of tubercu- 

 losis approaches the prevalence in the badly infected countries 

 abroad. There are herds in this country that are infected to the 

 extent of 100 per cent, of their members, and it could be no worse 

 than that anywhere. This degree of infection has been found in iso- 

 lated instances in every Eastern State. So it is evident that condi- 

 tions exist in some parts of the United States that are decidedly fav- 

 orable to the progress of tuberculosis. 



"The slaughter house statistics of European countries show the 

 frequency' of tuberculosis among the animals killed for food. In Hol- 

 land, about 13 per cent, are tubercular; in Prussia, 15 per cent; in 

 Saxony, 30 per cent.; and in some slaughter houses one-half of all 

 cattle killed are tubercular. In England, McFaydean says 30 per 

 cent, of the cows are tubercular. Of course, these are not American 

 statistics but they show to what extent the disease will spread under 

 certain conditions. We have the words of Professor Nocard, the 

 greatest French authority, and of Professor P>ang, of Denmark, for 

 it that tuberculosis causes far more loss than cattle plague, foot and 

 mouth disease, anthrax and pleuropneumonia combined. Moreover, 

 serious losses from tuberculosis of swine result from feeding skim 

 milk and buttermilk from tubercular herds. 



''Some of the supernatural individuals who write for papers, are 

 in the habit of lightly throwing aside European experience as (hough 

 it were of no consequence to us. On this point President Charles W. 

 Eliot, of Harvard Universtiy, has said: "It is a disgrace to organized 

 education that any nation should refuse, as our own people are so apt
