The ventilated privy system descriptionbed here is simple, cheap and effective and employs the forces of nature alone to overcome the passage of disease. By doing so It can be relied upon to maintain protection, without supervision for long periods of time. Properties such as these are very desirable and make the extra effort of digging pits deeper, wider or simply digging more of them certainly worthwhile. The ultimate aim, of course, would be to provide one privy for every family, a possibility which the present system may allow.
