by mechanicaland natural processes. As the result of many investi-gations and experiments it has been found that certainmicro-organisms, technically known as anaerobes, be-cause they thrive without air, are capable of reducingsolid organic matter to liquids and gases. Other bac-teria, called aerobes, which are present in all fertilesoils, have the power to purify the liquid product byoxidation and nitrification, and thus convert deadorganic matter into pure water and harmless mineralelements needed for vegetable life. They are Naturesmethods of ridding the earth of undesirable animalmatter, and are at our disposal everywhere if only weprovide suitable conditions for the bacteria to multiplyand work to the best advantage. The system or labor-atory for this bacterial transformation is simple in itsconstruction, inexpensive, and consists mainly of twooperations: the collection of all waste matter into aseptic tank, and a subsequent distribution to the soil iyo THE FARMER HIS OWN BUILDER

SANITARY DISPOSAL SYSTEM 191 by subsurface irrigation. The first step converts thesolids into liquids and gases, and effects about a 40 percent, purification. The second operation oxidizes orburns up the impure gases and thereby completes thepurification. SETTLING CHAMBER The basic idea, then, or keynote to a successful plantlies first in providing a suitable settling chamber, wherethe raw sewage may become finely divided or highlydiluted; second, in applying the diluted product to thesoil alternately with plenty of air, or what is termed theintermittent method of operating a plant. Thetheory is quite apparent: the aerobes or bacteria livein the air in the soil near the surface of the ground, andshould be fed with the sewage—but not drowned in it.They must have a breathing spell, so to speak. Hence,if sewage is applied continuously and in such a con-centrated form that the system is kept saturated, thefilter or disposal area becomes water-logged or sewagesick and ceases to be effect
