    fixed in a pen-stock chamber beneath the Promenade, serve to kee]) all sea water from the sewage chambers and sewers whilst the outfall is tide- locked. Sewage is discharged immediately the level of the sea is below the le^’el of the sewage in the storage chamber, until ij- hours below low water, when the valves are again closed. Both the Sewer outfall and the Spen Dyke surface water outfall terminate sea-ward, at a depth of about five feet below the lowest level of low water of a high spring tide. During the re-construction of the penstock chamber necessitated by the widening of the Promenade, storm overflow pipes were provided to rehevc 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. (\-.) A smaller system takes the sewage from a portion of Clare- mont Park, and from an estate in Claremont Ward, which contains Cheltenham, Chesterfield, Chfford, 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 Gyun, 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, but I am informed by the Borough Surveyor that a commencement has been made with a system of ventilating the sewers by means of tall columns 30 to 40 feet in height, placed at intervals of about 200 yards, and in such positions as not to be a nuisance or injurious to the inhabitants of adjacent houses. Practically all the surface ventilators ha\’e been closed. COLLECTION OF EXCRETA AND HOUSEHOLD REFUSE. Black])()ol is almost entirely a water carriage town. There are no cesspools or pail closets or privies in any of the inhabited parts, but on the outskirts there are a few of these. On the extension of the sewerage
