Among aromatic and ornamental plants may be mentioned magnolias, camellias, clematis, several kinds of roses, dahlias, ylang-ylang, papua, jessamine, and many species of orchids and ferns. These, however, grow wild in such profusion that little care is bestowed upon their cultivation. —Gardener's Magazine.

AMONG minerals of economic importance carbon minerals hold the unique position of being at the same time of the most common and the most rare occurrence. As far as external appearance indicates, a piece of common coal and the most brilliant diamond are widely separated; with regard to chemical composition they are closely related. Intermediate between the coal of the stoke furnace and the "brilliant" of the jewelry shop is still another well-known form of carbon, the graphite of the lead pencil. These three substances comprise the far greater part of carbon-containing minerals.
