The Bedouins do not make cheese. The milk of their sheep and goats is shaken into butter or turned into curds: it is rarely or never drank fresh, new milk being thought very unwholesome, as by experience I soon found it to be, in the Desert. The sour milk, or sheneena, an universal beverage amongst the Arabs, is either buttermilk pure and diluted, or curds mixed with water. Camel's milk is drank fresh. It is pleasant to the taste, rich, and exceedingly nourishing. It is given in large quantities to the horses. The Shammar and Aneyza Bedouins have no cows or oxen, those animals being looked upon as the peculiar property of tribes who have forgotten their independence, and degraded themselves by the cultivation of land. The sheep are milked at dawn, or even before daybreak, and again in the evening on their return from the pastures. The milk is immediately turned into leben, or boiled to be shaken into butter. Amongst the Bedouins and Jebours it is considered derogatory to the character of a man to milk a cow or a sheep, but not to milk a camel. The Sheikhs occasionally obtain dates from the cities. They are either eaten dry with bread and leben, or fried in butter, a very favorite dish of the Bedouin.[125] To this spare and simple dish the Bedouins owe their freedom from sickness, and their extraordinary power of bearing fatigue. Diseases are rare amongst them; and the epidemics, which rage in the cities, seldom reach their tents. The cholera, which has of late visited Mosul and Baghdad with fearful severity, has not yet struck the Bedouins, and they have frequently escaped the plague, when the settlements on the borders of the Desert have been nearly depopulated by it. The small pox, however, occasionally makes great havoc amongst them, vaccination being still unknown to the Shammar, and intermittent fever prevails in the autumn, particularly when the tribes encamp near the marshes in Southern Mesopotamia. Rheumatism prevails somewhat, and Ophthalmia is common in the Desert as well as in all other parts of the East, and may be attributed as much to dirt and neglect as to any other cause. The Bedouins are acquainted with few medicines. The Desert yields some valuable simples, which are, however, rarely used. Dr. Sandwith hearing from Suttum that the Arabs had no opiates, asked what they did with one who could not sleep. "Do!" answered the Sheikh, "why, we make use of him, and set him to watch the camels." If a Bedouin be ill, or have received a wound, he sometimes comes to the nearest town to consult the barbers, who are frequently not unskilful surgeons. The women suffer little in labor, which often takes place during a march, or when they are far from the encampment watering the flocks or collecting fuel. They allow their children to remain at the breast until they are nearly two and even three years old, and, consequently, have rarely many offspring.
