The current should be sufficiently strong to pre- vent deposits, which might, in time, silt up the channel, or cause a nuisance by their decomposition. 3. The sweep of the current should be such as to prevent the stranding along the shore of unsightly or otherwise objectionable objects contained in the sewage. 4. There should be no suspicion of contamination of water used in the town, or at a distance from it, as a drinking supply, and there should be no considerable fouling of a stream used for watering cows. 5. The fouling of water used in industrial processes, where clean water is required, is actionable. The possibility of this should in certain cases be regarded as a bar to crude discharge into a stream. Where these conditions can be satisfied, crude dis- charge, or discharge after very partial cleaning, is often to be recommended. At the same time, we must have an eye to future conditions and requirements, as well as to those of to-day. With a view to these, it is some- times advisable so to regulate the alignment of the sewers that the possible future need of interception and artificial purification may be met without too much change of existing work. Due regard should be had to the interests and to the legal rights of riparian owners on the stream below the town, or of littoral proprietors within reach of the tidal
