According to a circular before us this is an association for the promotion of planting and protection of trees; the erection of drinking fountains, and otherwise to suggest and carry out measures to render the city of Brooklyn more attractive. The society has rooms where trees, ornamental plants, flowers, and garden ornaments of every description are received, exhibited and the meritorious encouraged. Just why a body like this should not be called a horticultural society it is difficult to imagine, except that a large number of horticultural societies have degenerated to mere fruit-growers' meetings, and have abandoned all endeavors to foster a spirit of true horticultural improvement in the community. The Brooklyn folks, evidently ashamed of the degeneracy, have thought it best to select some other name.
