Everyone keeps looking for sings of water. Then one day the men see patches of green grass. There are pools of water in the hollows. Men and animals begin to hurry, for they know that rain has fallen nearby. Farther on, they find enough grass for pasture and enough water in the hollows for their animals. Chief Omar gives the signal to make camp. Again the camels kneel. And again the men unload them. Quickly they put up their tents, with the openings facing east. They spread rugs and blankets on the ground and place pillows on them. A blanket divides the tent into two rooms. Then they unload the dishes and pots and bags of food and water. And one more the nomads are at home. Meanwhile the thirsty animals take a long drink at the water holes. The goats drink first. Next come the sheep. Then come the camels. They are the thirstiest of all. They drink and drink. They have travelled for days without water. But a last they, too, turn away. Rain has fallen here, and there will be pasture for many weeks. The animals will grow fat on the green grass. Then the men will choose the animals they want to sell. After they shear the sheep and fill the bags with wool, they will go to the big town on the oasis. Again the nomads break camp and move on. they pitch their tents on the sand at the edge of the oasis. The first days in town are exciting days. There is the excitement of seeing shops and streets and crowds of people. The men must sell their animals and wool, and buy supplies. They bargain at the bazaars, and they drink coffee in the cool shade and listen to the sound of flowing water. But soon the men become restless. They begin to miss the freedom and the quiet of the great open deser. Then one morning the black tents are gone. Far out from the oasis a caravan moves slowly out of sight.
