The Arabs preferred to think of saving their own lives. So terrible was the sand-storm that the Bedouins could neither sit on the camels, nor could the camels remain standing. Chamis and Gebhr sprang to earth to hold the curb-bits, which were fastened under the lower jaws of the animals. Idris pushed Stasch off the back of the saddle and endeavored to control his camel. The animals stood with their legs far apart so as to resist the raging storm, but strength failed them, and the caravan was blown about in the sand, which pricked like pins, and torn to pieces as though with lashes from sand-thongs. Slowly at first, then faster, they began to twist and stagger as the hurricane advanced. From time to time the sand whirls dug grave-like hollows beneath their feet, or the sand and gravel, rebounding from the flanks of the animals, instantly formed hillocks, which reached up higher than their knees. In this manner hour after hour passed, the situation becoming more and more alarming. Idris at last realized that the only means of deliverance lay in remounting the camels and racing with the storm. But that meant returning in the direction of Fayoum, where Egyptian courts and the gallows awaited them.

“Ha! There is nothing else to be done,” thought Idris. “The hurricane has delayed our pursuers also, and as soon as it ceases we will gallop once more toward the south.”

So he cried out for them to remount. But just then something happened that completely changed the situation. The dark sand-clouds, now almost jet black, were suddenly permeated with bluish light. Then the darkness grew still more intense, and now arose in the higher regions of the air the slumbering thunder. Awakened by the whirlwind, it began to roll loudly, threateningly, and angrily between the Arabian and Libyan deserts. It seemed as if mountains were falling from the sky. The deafening noise increased; it made the earth tremble, and began to encircle the entire horizon.[[7]] From time to time the sound crashed with such terrible force that it seemed as though the firmament was broken and falling to earth. Sometimes it was like a hollow, distant rumbling; then again it broke forth still louder, flashed its blinding lightning, threw thunderbolts, rose and fell and crashed again. This continued a long while.

At last the wind ceased, as if terrified, and after a long, momentous pause the doors of heaven closed and a stillness as of death ensued.

A little later the voice of the leader rang through the silence:

“God is over the storm and hurricane! We are saved!”

They started off again; but the darkness was so impenetrable that although the camels ran side by side, their riders could not see each other, being obliged to call out every minute so as not to become separated. From time to time the lightning pierced the sand-filled air with vivid blue and red flashes, and then the darkness became so intense that it might almost be felt. Despite the confidence that the leader inspired in the Sudanese, they still felt uneasy, for they ran on blindly, not knowing where they were going, whether turning round in a circle or going toward the north or south. The animals stumbled every minute and made but little speed, panting so peculiarly and breathing so hard that it seemed to their riders as if the whole desert was gasping from fright. At last came the first large raindrops that generally follow a hurricane, and the leader shouted through the darkness:

“Khor!”

They had reached a ravine. At first the camels stood motionless at the edge, then began to descend very carefully.
