No. 4.] CATTLE COMMISSIONERS. 563 



this source of danger is greatly miniraized, when we consider other 

 possibilities of infection. 



Careful and regular inspection of dairy herds by competent 

 veterinarians is, in my opinion, a duty that the State should not 

 ignore ; but that the inspectors should limit themselves to the 

 detection of tuberculosis only, I believe to be unwise. Various 

 inflammatory and septic conditions of the udder, for instance, are 

 acknowledged causes of bad, unwholesome milk ; it is, therefore, 

 evident that milk from such udders should never be used. Pure 

 milk, however, is dependent upon the general health of the ani- 

 mals supplying it, and this, in turn, is dependent upon good 

 hygienic surroundings. Bad hygienic conditions, again, are con- 

 ducive to the spread of tuberculosis ; hence, broad work in this 

 direction would materially assist in reducing the amount of tuber- 

 culosis in cattle. Therefore, until manifestly sound laws for the 

 direct suppression of tuberculosis in cattle are forthcoming, there 

 is a wide field for energetic labor which indirectly will gradually 

 be attaining a similar end. 



Respectfully submitted, 



LANGDON FROTHINGHAM.
