this water is good enough to drink; but it is not so, for you 

 have not removed the bad matter entirely but have liquefied it 

 and only made it possible to more easily dispose of the sewage. 



The protection of the water supply by taking care of the 

 sewage in this way would solve many vexatious problems. 



How far-reaching the effect of using impure water may be 

 can be illustrated by the thought of the awful possibilities of 

 spreading a contagious disease by using this bad water to wash 

 milk utensils, and as a means to cool milk by standing the cans 

 in a tub of water in which there may be germs of typhoid fever. 

 A farmer might be ever so particular about his cow barn, his 

 cattle and himself and then use polluted water and thus his 

 precautions be unavailing. 



To illustrate the successful use of this system of sewage dis- 

 posal I would like to tell you how, at Sugar Hill, New Hamp- 

 shire, where the people depend upon money made by taking 

 summer boarders, there were installed, at the suggestion of the 

 New Hampshire State Board of Health, 30 or 40 of the tanks 

 to eliminate a fly pest that was so severe that the summer 

 people all went away. The help of the State Board was asked 

 to remedy the difficulty, and an investigation showed that the 

 flies were breeding and feeding in the open cesspools, privies 

 and sink drains that were common at almost every place. 

 After the sewage was taken care of by this method the flies 

 disappeared and the summer people now go there as before. 

 In their official reports they speak of the work and also pub- 

 lished plans of a tank as designed by them. 



The United States government and different States and col- 

 leges approve of this method of disposing of a serious menace to 

 health in rural communities. 



If you have conditions out of the ordinary by all means con- 

 sult some one who understands the question thoroughly before 

 spending your time and money. 



The cost of the tank if constructed by your own labor should 

 not be over $16 or $17; of course it is hard to say how much 

 the piping would cost, as the lengths would vary for different 

 cases.
