The hard stems are converted into bows, arrows, quivers, lance-shafts, masts of vessels, bed-posts, walking-sticks, poles of palanquins, rustic bridges, bee-hives, water-pipes, gutters, furniture, ladders, domestic utensils and agricultural implements. Split up finely they afford a most durable material for weaving into mats, baskets, window-blinds, ropes and even sails of boats. Perhaps the greatest use to which they are put is in building, for in India, China, Japan, Assam, Malay, and other countries of the East, houses are frequently constructed solely of this material.

Betel-nut (Areca Catechu), a palm cultivated in tropical Asia. The seed or nut resembles a nutmeg in size and in color. Pieces of this nut are rolled up with a little lime in leaves of Piper Betel, the Betel-pepper, and chewed by the natives. The pellet is hot, acrid, aromatic and astringent, tinges the saliva red, and stains the teeth. Its charcoal is used as toothpowder.

Cultivated extensively in the East Indies, where the consumption of leaves by chewing with the areca nut is enormous. Narcotic stimulant.

Cinchona, a genus of evergreen trees, includes thirty-six species, about a dozen of which are utilized. They are natives of the Andes, growing mostly between five thousand and eight thousand feet above the sea-level. It is the source of quinine, the most important drug in tropical medicine, and widely used throughout the world. Its cultivation is becoming quite extensive.

The bark introduced into Europe in 1639 by the Countess of Cinchon, whence the name. Now extensively cultivated in India, Japan, Ceylon and Jamaica.

Cotton (Gossypium herbaceum) is one of the most important cultivated shrubs. It is an annual and grows from two to four feet in height, with stalks branching extensively. At the bottom of the stalk the limbs are longest, and at the top they are light and short.

The flowers are white, or pale yellow, or cream-colored the first day. They darken and redden on the second day, and fall to the ground on the third or fourth day, leaving a tiny boll developed in the calyx. This boll develops and enlarges until maturity, when it is somewhat like a hen’s egg, both in size and shape. This boll is the house of the seed and lint—the products of commerce. In it are from three to five apartments or cells (often more than five in improved types), which hold the lint from its earliest formation until it is picked in the fall. The bolls of the cotton plant mature all the way from the last of August until frost attacks them. When matured, the fibrous wool, known as seed cotton, is gathered, ginned, and baled. When separated from the seed the lint becomes the cotton of commerce.

The chief commercial types of cotton are American upland, sea island, Egyptian, India, Brazilian and Peruvian. These differ in the length of the individual fibers (staple). The quality is indicated by the grading under such names as fine, good, good fair, fully fair, middling fair, good middling, middling, etc. Sea island cotton has the longest staple and is used for the finest qualities of yarn and fabrics. Egyptian cotton also has a long staple. Large amounts are imported into the United States.

Cotton is next to corn the most valuable farm crop of the United States. Nearly three-fourths of all the cotton produced annually in the world is grown in the south Atlantic and gulf states. The remainder comes mostly from India, Egypt, China, Brazil, and Asiatic Russia. A comparatively small percentage of the crop is sea island cotton from the coast of Georgia and from islands in the West Indies. The area of cotton production is spreading in the United States as well as in foreign countries.
