Adal, Or Adel, a portion of the E. coast of Africa, between the Abyssinian highlands and the Red sea, and extending from the bay of Tajurra to Cape Bab-el-Mandcb, and from thence 300 m. along the shore of the Red sea to the town and harbor of Massowah; lat. 11° 30' to 15° 40' N. It is inhabited by the Dana-kil or Affar, a Mohammedan nation, from the most famous tribe of which, Ad Alli or Adaiel, its name is derived. The territory of Adal varies from 120 m. wide at the bay of Tajurra, to only 40 m. opposite Annesley bay. There is a low tract along the coast, which rises gradually to a height of 2,000 feet above the sea in a distance of 25 or 30 m., and then the ascent is very rapid to the table land of Tigre. On the highest terraces durra and barley are cultivated in small patches. Camels, mules, asses, goats, and sheep abound, the pasturage is generally good, and large quantities of butter are annually sent to Massowah, and thence to Arabia. Wild animals are numerous, and even the lion and elephant are occasionally seen. A largo plain, called Harho, is covered with salt three feet thick, which is not only used for culinary purposes, but in Abyssinia as a currency. Adal is peopled by many tribes, which appear to belong to the same stock.

They are of a dark brown color, muscular and full in body, with roundish face, thick crisp black hair, lively eyes, lips thinner than those of the negroes, and short straight nose, divided from the forehead by an indentation. They all live a nomadic life, travelling with their flocks and herds from pasture to pasture. The sultan of the Adaiel resides at Tajurra, and the sultan of the Mudaito Danakil at Aussa, near the Hawash, 80 m. W. by 8. of Tajurra. Salt is the only commodity exported.
