CHAPTER XXVI. 



SEWAGE DISPOSAL FROM DAIRY AND DWELLING. 



To secure a high degree of sanitation in and about 

 the dairy house it is necessary to see that proper 

 disposal is made of the sewage from both the dairy and 

 the dwelHng. Where the latter is situated close to the 

 dairy house its surroundings may do fully as much harm 

 as those of the dairy itself. 



With open privies and the careless dumping of kitchen 

 slops near the dwelling, we have a double means of en- 

 dangering the dairy. If the ground near the dwelling 

 and privy slopes in the direction of the water supply, the 

 latter is likely to become contaminated through seepage in 

 the manner indicated in Fig. 63. In addition to this there 

 is the danger of flies carrying various kinds of bacteria 

 from these places to the dairy house. Flies not only carry 

 the obnoxious, putrefactive species, but too often also 

 the deadly pathogenic kinds, such as cause typhoid fever, 

 to say nothing of the ofifensive excrementitious matter 

 conveyed in this manner. 



Obviously the accumulation of sewage about the dairy 

 house is attended by practically the same danger as that 

 arising from the unsanitary surroundings of the dwelling. 

 Moreover there is certain to be trouble also from bad 

 odors.
