THE effect of coal smoke on foliage in London gardens has had conspicuous attention directed to it by Sir Alfred Mond’s reception of a deputation of the Coal Smoke Abatement Society at the Ministry of Health. At Kew coal smoke and the presence of sulphurous acid in the air have long been considered two of the greatest difficulties with which it has to contend. In winter it is almost impossible to cultivate certain evergreen trees. The worst wind for carrying it comes from the north and north-east. The smoke is worst when it takes the form of dense fog. A fog of a few hours will make the flowers and leaves of many indoor plants fall. Everything outdoors becomes covered with a thick deposit of greasy soot. The breathing pores of leaves become clogged and the plants are enfeebled.
