MR. CHOKLTON returned to the subject in a recent paper read before the Royal Society of Arts (J. Roy. Soc. Arts, Feb. 23, 1934), in which he directs attention to the policy of Great Britain, which has allowed water supply to remain in the hands of local authorities without any national plan devised in the interests of the population as a whole. As a result, there are 1,100 separate water undertakings in the country with a mosaic of disconnected entities and interlocking boundaries. Urban areas are best served, but many rural areas require adequate provision. A hydrogeological survey is needed before plans on a large scale can be matured. Furthermore, some pooling of supplies is essential because of the vagaries of rainfall within any given year, and lastly, special storage reservoirs should be constructed to serve abnormal demands in dry seasons. These might be in the Thames valley, for the south generally; in south Lincolnshire for the Ouse flood waters; and in the Lake District to serve the industrial areas of Lancashire. Such undertakings would, according to Mr. Chorlton, have many advantages in providing a certainty of good water in all areas, and a possibility of encouraging increased use of water without alarm of shortage, while the expenditure on labour would decrease unemployment for some years to come.
