A frame being fixed on the back of the animal, the bride is placed in it, and, while thus sitting, is housed over with carpets, shawls, and ostrich feathers. In travelling from place to place, or in searching for pasture ground, the people make use of these frames; but they are in such cases generally uncovered, and have baskets, or other frame-work, attached to their sides, in which the young children are placed. An Arab family on its march presents a very extraordinary appearance, the camels being laden with tents, cooking utensils, women, and children. The men walk, driving their flocks before them, or ride their horses, frequently without bridle or saddle. Should the journey exceed one day, a temporary tent is erected at night; and at the dawn of morning, all is again placed on the camels. The operation of erecting or taking down one of their hair houses does not occupy much time, as the women always assist the men on these occasions. The dogs guard the flocks during the night, and are very fierce. In colour they are white, resembling wolves in form, and having long bushy tails. They howl rather than bark, and with great apparent courage attack every stranger who approaches them, though when threatened with a stick or stone, they run yelping away. It frequently happens, that the spot fixed on as a temporary residence is far distant from any well, sometimes even three days of the ordinary march of flocks; yet this does not dishearten the persevering Arab, who, notwithstanding, drives his sheep once a week to drink. They feed as they go and come, and therefore do not suffer much on their long journey. The wants of the people are easily supplied; a few skins of water being brought at stated times by a camel, and economised with great care. I have remarked, that not only the Arabs and their camels, but all animals in this country have the power of remaining a great length of time without water. Sheep, (provided they have tolerable herbage), will pass even a month without drinking. Antelopes and buffaloes, I should conceive, in some cases never taste water, none being found on the surface of the desert, and they are unable to obtain that which is in the wells. On the other hand, wolves, hyænas, foxes, and jackals, are less capable of enduring thirst. They descend such wells (or more properly pits) as are not deep; and the vicinity of one of these places is frequently ascertained from observing the tracks of animals, which, during the night, go there to drink.
