fore, be carried in ice under certain favorable conditions. 

 They are not killed by dessication and may, therefore, 

 be blown about in dust. A few hours exposure to strong 

 sunlight, however, or boiling proves fatal to them. 



The infection of the water-supply is, perhaps, the most 

 serious source of danger. Cisterns may become polluted by 

 leakage from privies or sewers through cracks in the walls 

 or by filtration through porous walls which filter out the odor 

 and appearance of sewage but still transmit the bacilli. It 

 is obvious then that in cities like our own universal sewer 

 connections should be required and a pure water supply made 

 available in order that all cisterns may be abolished. 



Danger of contracting typhoid fever then usually comes 

 from improper regard for the following conditions : Drink- 

 ing infected water; eating uncooked vegetables sprinkled 

 or washed with infected vv^ater; using eating utensils, espe- 

 cially those used for milk, cleansed in infected water; 

 eating raw oysters subjected to the absurd process of 

 "fattening" in river water usually packed with bacilli; and 

 improper screening from flics, v/hich are knov/n to carry 

 bacilli from privy vaults on their feet and thus infect food.
