or MOKHA, a city and seaport of Arabia, in the province of Yemen, is situated on the Red Sea, about 40 miles N.W. of the Straits of Bab-el-Mandeb; Lat. 13° 20'. N., Long. 43° 20'. E. The town is built on the edge of a sandy plain, near the shore of a bay formed by two low promontories, on which are built forts for the protection of the harbour. The city, when viewed from the sea, presents a striking and beautiful appearance, as the houses along the shore, which are the best in the place, are high, well built, and white-washed; while in the background several mosques are conspicuous, one of which is of great size. On a nearer approach, however, Mocha is by no means so attractive; for its appearance is mean, and it is disfigured by ruinous buildings and dirty streets. The city is surrounded by walls, but the fortifications are not of great strength. The principal building is the residence of the dola, or governor. The bay is accessible to vessels drawing 10 or 12 feet of water, but those of a larger size are obliged to anchor in the roads outside the bay. The principal article of export is coffee, for which Mocha is famous. The plant does not grow in the immediate neighbourhood of the town, which is a barren desert, but among the forests and hills of the interior, whence the beans are conveyed and sold to the Mocha merchants. Before the beginning of the present century the great demand for coffee in Europe contributed greatly to the wealth and prosperity of Mocha. Since then, however, the cultivation of coffee in the West Indies, and its exportation from thence at a cheaper rate, have affected the coffee trade of this port. The quantity annually exported is estimated at more than 10,000 tons. The principal other exports of Mocha are—dates, gum of various sorts, frankincense, myrrh, balm, gold-dust, ivory, sharks' fins, rhinoceros' horns and hides, aloes, &c.; and the principal imports are rice, iron, hardware, &c. The trade of Mocha is chiefly in the hands of Banian Indians. Pop. 7000.
