ous to the business, and a source of annoyance to 

 every one who comes near the place. 



Irrigation* Where the factory is above a sloping 

 field or plot of land, the sewage may be used for 

 irrigating purposes with satisfactory results. It is 

 necessary to have a large storage tank or tanks in 

 order that the sewage may be applied when needed 

 by the crop. Roots, grass, garden truck, orchards, 

 and nursery stock are most benefited by the applica- 

 tion of factory sewage. Where the conditions are 

 favorable the factory owner may use this during the 

 summer time for forcing garden and other crops. It 

 will pay for the expense in a very short time. There 

 is no reason why a small plot of ground favorably 

 situated might not be used for growing all the fruit 

 and vegetables required on the table. The men 

 would relish this addition to their regular fare, and 

 the cost of " boarding the hands " may be very much 

 reduced. 



TANK OR BLIND WELL. 



With a porous subsoil the sewage may be allowed 

 to soak from a tank or blind well. It is very import- 

 ant that this tank or well shall be located in such a 

 position that there is no danger of polluting the water 

 supply for the factory. If the water supply be drawn 

 from a well, then the two must be at least 300 feet 

 apart. 



The sewage may be pumped from a tank and be 

 drawn to adjoining fields, but this plan as a rule 

 involves too much labor to be profitable.
