THE Times Trade and Engineering Supplement of July 28 contains a special section devoted to a consideration of “Water Economy and Supply”. In view of the continued predominance of the topic of the drought, the appearance of a symposium of the opinions of various competent authorities, including engineers and men of science, on the subject is undoubtedly opportune and appropriate, though it appears that the publishers, when the idea was first mooted, entertained misgivings lest a change of weather might destroy the basis of the number before its publication. The first article on “Lessons of the Drought”, by Sir E. Hilton Young, the Minister of Health, is generally of the nature of a reassuring statement calculated to allay public anxiety. “There is,” he says, “great need for care and attention to the situation, but none for alarm.” He counsels economy in the use of water “where reserves are not abundant”, and recommends water undertakers to look ahead and “assume that the drought will continue in large measure until the rains of November and December and that even then there may not be more rain than last year, when it was much below the normal”. The Water Shortage Act, passed in May last, has proved of signal service in enabling water authorities to augment their supplies.
