|Ground polluted with kitchen refuse containing large amounts of fatty
material and soap becomes diseased, so that the natural fermentation
changes fail to take place, and the soil becomes "sewage sick" and gets
in such a condition that vegetation will not grow. Failure to properly
dispose of kitchen refuse is frequently the cause of the spread of germ
diseases, through the dust and flies that are attracted by the material
and carry the germs from the refuse pile to food.
