CHAPTER XXXXII. 
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 dwelling. 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 offensive 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.
