A Correspondent of the Southern Cultivator recommends the following for training over arbors, etc.: Upon the arbor in the center is twined the splendid Cloth of Gold and the beautiful crimson Queen of Ayr-shires, the flowers large and full, and the contrast of colors is very fine. It is well to train these running roses to arbors that they may be kept within bounds, for they grow so rapidly as to require the free use of the scissors, and need close tying to the sides and top. The Cloth of Gold can be trained to represent a miniature tree, by cutting back the branches and keeping one main stem. This stem in a few years becomes quite large and strong, and can support a good sized head. As the flowers of Roses are always produced on the new spring growth, the eutting back does not interfere with a fine display of blooms. There are several Roses here trained in this manner and produce a charming effect, being now covered with a profusion of elegant flowers. Here is the Luxemburg, which is about eight feet high, with a large strong stem, and a fine symmetrical head. The splendid flowers upon it shows that this manner of growth suits it remarkably well.

The Devoniensis to its right, is quite large enough to accommodate a comfortable bench underneath its shade, and its large creamy flowers hang in graceful' profusion around.

The hybrid perpetual Roses are loaded with elegant blooms. They can be cultivated within such limited space, that a good many can be accommodated in any ordinary sued bed. It is best to train them up to stakes as their stems are slender and are apt to fall to the ground when loaded with heavy clusters of flowers. Every one has favorites; among mine is the General Jacqueminot with its brilliant crimson flowers, so large and bright that the eye is dazzled while looking at it; also, the Caroline de Sansal with such clear flesh-colored petals, so pure and delicate in its setting of dark rich leaves; the Jules Margot-tin is exceedingly rich, its carmine purple flowers are so double, it seems almost impossible that so many petals could be collected in one flower.
