We hear that in India, in spite of the earth system, typhoid is rife, and the opinion is very general there that typhoid spreads through the air. I have never been in India, and am not competent to express any opinion, but I have heard that in some places in India the excreta are _deeply_ buried, and if this be the case, it appears to me that if the ground gets deeply fissured during drought, the torrential rains which follow may very well wash this too deeply buried and unchanged excreta into the water sources. If excreta are to be used for agricultural purposes, no chemical antiseptics must on any account whatever be mixed with them. Antiseptics are a source of serious danger to the agriculturist. The best antiseptic for such a purpose is earth. IN-DOOR EARTH CLOSET. It has been supposed that the method of excrement disposal which I advocate necessitates the compelling of delicate persons to go out of doors in all weathers. I do not believe that it is necessary to ask delicate persons to run the risk of exposure in houses where dry methods of excrement disposal are employed. If a very small amount of the ingenuity which has been lavished upon water carriage had been devoted to overcoming the difficulties which attend the safe and decent management of dry methods, these difficulties would, I believe, have long since disappeared. If architects and builders can be impressed with the _necessity_, on scientific, moral, sanitary, and economic grounds, of overcoming these difficulties, the thing is done. The house which I own at Andover (see fig. 14, B) becoming vacant, I tried the experiment of giving it a dry privy, which should be of such a kind that no lady would object to use it. Now I hold that every closet, whether a dry closet or a water closet, should be sequestered from the main structure of a house, and should be approached by a lobby having cross ventilation. Those who in the present day put closets and waste-pipes within the four walls which enclose the living-rooms are not abreast of modern civilisation. The simplest plan for effecting my object in the present case seemed to be to throw an arch across the entrance to the stable yard, to place the ventilated passage on the top of the arch, and the closet on the far side of it, on a level with the first floor, and with a capacious vault or 'catch' beneath it. (See figs. 17 and 18.) The catch, though larger, is exactly on the same principle as that which has been described, and it has been provided with eight large air bricks, three of which are just below the level of the closet seat, three near the ground level, and two intermediate in position. The bottom of the door of the catch is about an inch above the ground level, and in addition there is an opening for a dust-shoot, protected by a fine grating, so as to insure that only dust and ashes and not cinders or clinkers are thrown into it. There can be no doubt that plenty of fresh air will get access to this receptacle.
