In large cities, like Philadelphia for instance, it is only with great difficulty that societies for the encouragement of general horticulture can be sustained. Brick and mortar push the gardens far into the suburbs, and the suburb on the north becomes farther away from the suburb on the south, than if there were no great city between them. But the cut flower trade and the trade in plants for temporary decoration, and kindred branches grow on just what the other loses, and becomes in time almost a commonwealth of its own. Recognizing this fact, the city florists of Philadelphia have determined to see what can be done in the way of forming a sort of City Horticultural Society, in which this sort of horticulture should be the great central idea. There seems to be no reason why such an organization may not prove a success. At any rate the attempt will be watched with interest elsewhere.
