Grazing for their camels, and herds of goats, and short-haired, lop-eared sheep, never lasts long in any one place, hence the nomad constantly shifts from one quarter to another. On occasions, owing to scarcity of vegetation, it is necessary to camp far out from water: a day, or a day and a half’s journey from the nearest point of supply. This means long treks to water for the herds, and a journey with camels at least once a week to fetch supplies in goat-skins for the pressing needs of camp. It is not uncommon to come upon one man, and, perhaps, two naked, athletic-looking, boys at a remote well-head in the open, alone on bare, sand-swept desert, with about eight to ten camels, employed on the task of filling goat-skins. Without surprise, they tell that they have eight, twelve, or fifteen hours’ journey before they will get back to their camp. In all likelihood they carry no food, and will not eat till they get home, unless one of the camels should chance to be a female with milk. The frail, gipsy-like huts of the Tuaregs are usually domed to shape like exaggerated mole-heaps. A dozen slim poles and lighter laths cut from acacias or palm-leaf stems, bent over and laced to form a framework, some grass matting and tanned skins indiscriminately thrown over them, and tied down in rude patchwork disorder, compose their low-crouched, diminutive dwellings wherever they select to pitch them near a chosen patch of grazing. Furnishing consists of a branch-built couch, about 15 inches off the ground. It occupies nearly all the floor space, and upon this the whole family are accustomed to sit or sleep, closely wedged together. In addition, there are a few equally primitive utensils, such as a couple of wooden mortar bowls and pestle-poles for crushing grains and herbs, some broken-edged calabash bowls and earthen jars and goat-skins, for holding food, milk, and water. But there end the main possessions of any nomad’s dwelling. The arms that defend them go abroad with the menfolk, or remain concealed. By their very humbleness these belongings have two qualifications that are commendable: they are easily moved from place to place; they are little to lose if abandoned in the panic of a raid. [Illustration: A TUAREG HOME] In their desert environment the nomads live in a constant atmosphere of sand, and surely there is nothing with greater discomfiting qualities. The clearings before the doors are sand, loose and trodden by the tread of live-stock and playful children. Wind and feet send it ever moving, outdoors and indoors; and clothes, food, and liquids, no matter how carefully guarded, are contaminated with an in-seeking, almost invisible dustiness. It is sometimes said of a creature that it “lived close to the earth”—_the Tuareg lives “close to the sand,”_ and knows no escape from it.
