[12] Bartema's account of its productions is as follows: "The soil beareth wheat and hath abundance of flesh and divers other commodious things. It hath also oil, not of olives, but of some other thing, I know not what. There is also plenty of honey and wax; there are likewise certain sheep having their tails of the weight of sixteen pounds, and exceeding fat; the head and neck are black, and all the rest white. There are also sheep altogether white, and having tails of a cubit long, and hanging down like a great cluster of grapes, and have also great laps of skin hanging down from their throats, as have bulls and oxen, hanging down almost to the ground. There are also certain kind with horns like unto harts' horns; these are wild, and when they be taken are given to the Sultan of that city as a kingly present. I saw there also certain kind having only one horn in the midst of the forehead, as hath the unicorn, and about a span of length, but the horn bendeth backward: they are of bright shining red colour. But they that have harts' horns are inclining to black colour. Living is there good and cheap." [13] The people have a tradition that a well of sweet water exists unseen in some part of the island. When Saad el Din was besieged in Zayla by the Hatze David, the host of El Islam suffered severely for the want of the fresh element. [14] The singular is Dankali, the plural Danakil: both words are Arabic, the vernacular name being "Afar" or "Afer," the Somali "Afarnimun." The word is pronounced like the Latin "Afer," an African. [15] Occasionally at Zayla--where all animals are expensive--Dankali camels may be bought: though small, they resist hardship and fatigue better than the other kinds. A fair price would be about ten dollars. The Somal divide their animals into two kinds, Gel Ad and Ayyun. The former is of white colour, loose and weak, but valuable, I was told by Lieut. Speke, in districts where little water is found: the Ayyun is darker and stronger; its price averages about a quarter more than the Gel Ad. To the Arabian traveller nothing can be more annoying than these Somali camels. They must be fed four hours during the day, otherwise they cannot march. They die from change of food or sudden removal to another country. Their backs are ever being galled, and, with all precautions, a month's march lays them up for three times that period. They are never used for riding, except in cases of sickness or accidents. The Somali ass is generally speaking a miserable animal. Lieut. Speke, however, reports that on the windward coast it is not to be despised. At Harar I found a tolerable breed, superior in appearance but inferior in size to the thoroughbred little animals at Aden. They are never ridden; their principal duty is that of carrying water-skins to and from the walls.
