When thus dried the soil may be conveyed about without any unpleasant smell arising therefrom. The walls of these buildings may be constructed of brick, stone, concrete, or other suitable material, and the roof should be so made 5 as to prevent the escape of any of the noxious gases arising from the sewage, for which purpose I prefer to coat the roof with felt or asphalte underneath the slating, which felt or asphalte may be laid on a base either of wood planks or thin iron sheets. The roof should also be provided with strong iron frames for skylights, and with man-holes, 10 so that men may be let into the pits for any purpose that may be required. The bottoms of the pits I prefer to face with concrete of sufficient thickness, and to construct with an inclination so as to facilitate the clearing of the pits. These pits may be used in connection with sewers 15 now existing. LONDON : Printed by George Edward Eyre and William Spottiswoode,
