Sewage disposal . al plan (the Fiddian)is shown in Fig. 95, as adapted to a rectangular bed. The feedpipe is a siphon which moves in a trough at the side of the sections of the discharge buckets empty in oppositedirections, and at the end of each excursion a lever collides with abuffer and deflects the sewage to the other set of buckets, whichdrive the apparatus back again to the end of the bed from whichit started. These Fiddian distributors are costly and requiremore power to drive them than do the revolving pipes. Theirfreedom from small openings liable to clogging, their adaptionto rectangular beds and the fact that they will operate underwidely varying heads, are strong points in their favor. Where there is insufficient head for any of these automaticdevices, power-driven sprinklers have been introduced in manyEnglish towns. One of the earliest of these was devised by and is shown in Fig. 96 as it was used in experi- THE DISTRIBUTION OF SEWAGE ON TRICKLING BEDS 337. Fig. 95.
