To make a desert of bricks and mortar bloom like a Garden of Eden—that is the great object of the National Gardens 'Guild; an object not so very hard to achieve, as those will realize who remember the transformation scene in Charlie Chaplin 's film, The Kid. That transformation was effected simply by the use of flowers, and, with window-boxes, as the yearly competitions of the Guild have shown, a drab and dreary house or street may be turned into a delight to the eye. This evening's talk on window-boxes is to be given by Sir William Lawrence , who, as Treasurer of the Royal Horticultural Society, speaks with the highest possible authority on everything relating to flowers.
