This valuable and useful animal has a ring put through its upper lip, to which is fixed a leathern strap which answers the purposes of a bridle; the saddle is similar to that used by the Moors, or what the mountaineers of Andalusia use. With a goat skin or (a bakull) a porous earthen pitcher filled with water, a few dates, and some ground barley,[88] the Arab travels from Timbuctoo to Tafilelt, feeding his heirie but once, at an oasis in the desert, for these camels, on an emergency, will abstain from drinking and from food seven days or more. A journey of thirty-five days caravan travelling will be performed by a Sebayee in five days; they go from Timbuctoo to Tafilelt in seven days. One of these animals once came from Fort St. Joseph, on the Senegal river, to the house of Messrs. Cabane and Depras, French merchants at Mogodor, in seven days. In the great desert of Africa, where cultivation is so rare that one may travel several days on an ordinary camel with baggage, without seeing any habitation, the use of the heirie must be evident, for it is more abstemious, and bears a longer continuation of fatigue, than the (Sh’rubah Er’reeh) desert horse, hereafter described. The self-exiled Muley Abdrahaman, a prince of undaunted courage and great penetration, son of the old Emperor, Seedy Mohammed bn Abdallah bn Ismael, of the Tafilelt dynasty whilst residing among the Arab clan of Howara in Suse, kept, night and day, at the door of his (keyma) tent, two heiries, ready caparisoned, one having a load of gold dust and jewels, and the other for riding, in case of a sudden surprise, that he might pass into the desert out of the reach of his father’s power. The Emperor’s soldiers, by their master’s order, having treated his highness’s woman in a manner disgraceful to a Mooselmin, he had retired to the confines of Sahara for more security. The swiftness of the heirie is thus described by the Arabs in their figurative style: “When thou shalt meet a heirie, and say to the rider, Salem Alick, ere he shall have answered thee, Alick Salem, he will be afar off, and nearly out of sight, for his swiftness is like the wind.[89]”
