FOR many years the National Smoke Abatement Society, from headquarters in Manchester, pursued its modest efforts to secure a purer air and for the last ten years it has issued a quarterly journal. Since its removal to London, its efforts have been accompanied by greater progress. Even Whitehall has almost gone over to smokeless fuel and the L.C.C. has become more active. The extensive rebuilding in progress all over Great Britain is providing an unusual opportunity to diminish atmospheric pollution. Even the coal industry, long indifferent to the manner in which its wares were consumed, is showing an increased desire to avoid the reproach of causing smoke. The Society has taken a further step by issuing its journal in a new form, larger, more ambitious and under the more attractive name of Smokeless Air. This will be issued quarterly at 1s. and for 2s. 6d. post free per annum. The first number of the new series is bright and well produced, containing news of the movement and interesting articles on the subject of atmospheric pollution. At its price it ought to receive a much wider circulation.
