    The resolutions adopted by the Croydon Local Board of Health were to the effect that— 1. Alter the date of approval, no new house should be passed as fit for occupation that did not have a cistern fitted to the w.c. on self-flushing principles. That water from such cistern should not be used for dietetic puiposes. 2. That every branch of drain going into the public sewer should be properly ventilated by an extension of the soil-j)ipe of the w.c. upwards and outwards. 3. If the drain is not intended for a w.c, then by a ventila- ting pipe inserted between the trap and the sewer, and as close to the trap as possible. 4. That all rain-water pipes be untrapped. 5. That all overflow pipes from cisterns, baths, and waste- water sinks or closets, be cut ofi' from direct communi- cation with the sewer. 6. That no communication with the public sewer, or any sewer-pipe, be covered up until it has been inspected by the proper officer of the Local Board. A most important and necessary rule, that all such commu- nication be laid upon concrete, was rejected by the Local Board. —Carpenter, op. cit., p. 3. In a special report on sewer ventilation in SaLford, Dr. Tatham advises the committee that in all cases where there is not sufficient space for the immediate dilution and destruc- tion of noxious effluvia, they recommend the council—either, (ft) To cause ventilating shafts to be erected at frequent inter- vals, in connection with the sewers, of a sufficient diameter, and of such a height as to safely discharge the foul air above the' roofs of the houses ; or (b) In case the present street grids are retained, to use every diligence in purifying the sewer air, by means of charcoal, before permitting its escape into the street. The first plan, viz., that by ventilation above the roofs, seems to me the better one, inasmuch as all obstruction to a free circulation of air in the branch sewers being removed, there is less fear of that dangerous pressure at the distal, or house end of the drainage system, which so frequently forces pesti- ferous gases through the water-traps of om- dwelHng-housos. The following are the conclusions from the first and second reports of the Select Committee on the sewage of towns, dated 10th A.])vi\, 1862 :— Analysis of Evidence. 1. The evidence proves that sewage contains the elements of every crop which is grown.
