SMOKELESS CITIES.

[TD TUE EDITOR OP THE .3PHOFATOR:1 Sin,—Though I am sure there will be no difference of opinion among your readers as to the almost intolerable evils caused by smoke in our great cities, I cannot agree that " there are practically no flowers and very few trees which can stand perpetual smoke" (Spectator, May 4th). I venture to enclose a list of trees and flowering shrubs that are at the present moment doing well in Hyde Park Gardens; while as regards flowers, we have an herbaceous border bright in summer with flowers too many to enumerate:—Trees I Acacia, tulip, thorn, silver birch, copper, beech, plane, catalpa, double-blossomed cherry, double-blossomed peach, laburnum, almond, ailantus. Shrubs : Lilac, hardy azalea, forsythia, rites, wistaria., magnolia (deciduous), pirus japonica, pirus mains floribunda, weigelia, rhododendron.—I am, Sir, em, P.S.—Should any of your readers be interested in the subject, I shall be very glad to show them over the gardens. •
