COFFEE, the seed of an evergreen shrub which is cultivated in hot climates, and is a native of Abyssinia and of Arabia. This shrub (Coffea arabica) Is from 15 to 20 feet in height, and belongs to the Rubiaceae. The leaves are green, glossy on the upper surface, and the flowers are white and sweet-scented. The fruit is of an oval shape, about the size of a cherry, and of a dark-red color when ripe. Each of these contains two cells, COFFEE PLANT and each cell a single seed, which is the coffee as we see it before it under- goes the process of roasting. Great at- tention is paid to the culture of coffee in Arabia. The trees are raised from seed sown in nurseries and afterward planted out in moist and shady situations, on sloping ground or at the foot of moun- tains. When the fruit has attained its maturity cloths are placed under the trees, and upon these the laborers shake it down. They afterward spread the berries on mats, and expose them to the sun to dry. The husk is then broken off by large and heavy rollers of wood or iron. When the coffee has been^ thus cleared of its husk it is again dried in the sun. A tree in great vigor will produce 3 or 4 pounds. The best coffee is imported from 4 — Vol. Ill — Cyc
