WHERE THEY LIVE 



Most bacteria grow out of doors on anything 

 that is moist and that contains food, either ani- 

 mal or vegetable. All decay is the result of the 

 growth of bacteria and moulds. Bacteria reduce 

 all living things to the simple earthly elements 

 of which they were formed. 



Great numbers of bacteria are attached to all 

 particles of decaying matter. Each speck of dust 

 blown by the air is a tiny airship carrying a 

 crew of living bacteria. Cow-feed and bedding 

 are coated with bacteria which feed upon them. 

 They follow feed into the intestines of the dairy 

 cows and grow inside the cow in great numbers. 

 The discharges from the intestines of dairy cows 

 are filled with uncounted millions of bacteria. 

 The dust of manure, the floor of the cow stable, 

 and the manure on the flanks of dairy cows are 

 loaded with intestinal bacteria. 



Old milk inside of milk pails, milk cans, or on 

 milk utensils, is the dwelling-place of enormous 

 numbers of bacteria waiting to contaminate and 

 injure any clean milk that may touch them.
