Theexcreta are received directly into the proximal end of the trap,and when the water is turned on the sides of the bowl arewashed clean and everything in the bowl and trap swept directlyinto the soil-pipe. There is no complicated mechanism to getout of order, the trap is always in sight, and the entire appa-ratus can always be kept clean and inoffensive, as there are nohidden corners or angles for filth to lodge. This form of closetis, all things considered, one of the best for general use.
