 must seek safety in the pasteurization or boiling of the 

 milk, or at any rate, must patronize the dairyman who 

 honestly endeavors to keep tuberculosis out of his herd.

 way into milk. Under favorable temperature condi- 

 tions, their increase may be very rapid and the milk 

 may then become the cause of a more or less serious 

 outbreak of typhoid fever. Many an epidemic of typhoid 

 has been traced to milk. Too much cannot be said 

 against the carelessness that makes such epidemics 

 possible. 



A few typhoid germs derived from polluted water 

 soon multiply to thousands in the warm milk, and, 

 when distributed along the milk route, bring disease 

 and perhaps death to many families. The dairyman 

 should remember that a few drops of water from his 

 well or brook, left in the milk can, is sufficient to bring

He should be careful, also, to exclude from his dairy-
