    Dyke, one of the principal watercourses of the district, originally emptied through an open watercourse into the sea near the Manchester Hotel. Later, the last few hundred yards were covered in, forming a culvert alongside the sewer chamber discharging at the foot of the ludking. In the last few years this culvert has been extended some distance inland, and recently the outflow of the culvert has been turned into the penstock chamber, into which the main sewer runs (the chamber being divided by a partition separating the Spen Dyke water from the sewage), and the S]:)en Dyke water now flows out by the old iron sewer outfall extended to the same point on the foreshore as the new sewer outfall. During the re-construction of the penstock chamber necessitated by the widening of the Promenade, storm overflow pipes were provided to relieve the sewage chambers during heavy rains with an incoming tide, and also a pumping chamber, if required, for use when the sewerage system is full at high tide. (v.) A smaller system takes the sewage from a portion of Clare- mont Park, and from an estate in Claremont Ward, which contains Cheltenham, Chesterfield, Clifford, Carshalton, and Handsworth Roads, etc., and also from a portion of the Gynn Estate, outside the Borough in the district of Bispham. This sewage flows by gravitation to an outfall at the Gynn, which extends seawards to a distance of 440 yards, sewage discharging at all states of the tide. A portion of this sewer has been defective for some time, owing to sinking in the peaty subsoil, and this portion is being relaid on piles driven through the peat into solid clay. Sewer Ventilation. There is no complete system of sewer ventilation in the Borough. Formerly all sewers constructed had ventilating open gratings near the manhole covers at the street level. Many of these caused considerable nuisance and annoyance, and a large number have been closed, without other provision being made for efficient ventilation. In some of the newer streets there is no proper ventilation, and undoubtedly this leads, at times, to the intercepting traps being forced and sewer air escaping at unsuitable places. There are a few high ventilating shafts in certain parts of the Borough, and others have been proposed, and, I understand, some are to be erected in the near future. I think it is of great importance that such shafts should be provided at all tha main dead-ends, and also
