An earth-closet is a toilet in which the faeces from the human body are received in a quantity of earth. The advantages of the earth-closet system are due to the fact that dry earth is one of the best disinfectants and deodorizers, and that the compound formed by the combination of the faecal matter and the earth is valuable and easily applied as manure. In large cities the earth-closet system would hardly be practicable on account of the expense of preparing and storing large quantities of earth, but in agricultural districts the system could be employed with great advantage, except for the inconvenience.
