    it is considered highly expedient that their flow should be accelerated by a complete flushing apparatus, having the floodgates placed across the sewer, say every fifty yards apart. By these means a large head of water is collected and suddenly discharged through the sewer as required. In the meantime, however, and until another and better supply of water can be introduced into the city, arrange- ments ought to be made with the present Water Company to flush all the sewers, at frequent intervals, which are with- in workable distance of the company's reservoirs at Kotten Row and Garnet Hill. 3d. In order to facilitate the flow of all sewage matter at the various junctions, it ought to be made imperative that all those junctions should be formed to a regular curve of a quarter circle, having as long a radius as possible, and that they should never be connected at right angles. These statements are supported by the following facts, as elicited by repeated experiments :— For a curved junction of 20 feet radius, resistance 100 For a curved junction of 5 feet radius, resistance 146 For a curved junction at right angles, resistance 316 4th. All the gully-holes in streets, as also every connection with main and branch sewers and drains, should be trapped upon the most approved principle, so as to prevent any effluvia from contaminating the surrounding atmosphere, or finding its way back through the private drains into the various dwellings of the city. 5th. Were the supply of water copious, the declivities of the sewers considerable, and the drains all properly con- structed as above described, the necessity of all flushing would be obviated, and comparatively little foul air would be generated. But in Glasgow, as in many other manufac-
