From Skeletons on the Zahara: A True Story of Survival, by Dean King (Little, Brown, 2004), Kindle pp. 4-6:
Like all successful caravan drivers, Ishrel was tough but just. Imposing and erect of bearing, the Arab leader had flashing eyes beneath an ample turban and a thick beard to his chest. He wore a long white haik of good cloth, befitting his status, drawn tight around his body and crisscrossed by red belts carrying his essentials: a large powder horn, flints, a leather pouch with musket balls, and his scabbard with a broad and burnished scimitar. He carried his musket night and day, always prepared for a sudden attack from the wild bedouins of the desert. His constant nemeses, however, were the terrain and the sun.
For six days, Ishrel’s caravan weltered in the deep drifts, the cameleers alternately singing to their camels and goading them with clubs, constantly dashing on foot here and there to square the loads. They gave violent shoves to bulges in woven sacks and tugged on ropes with the full weight of their bodies. For all their efforts, uneven loads were inevitable, causing strains to the camels’ joints and bones. It did not take long for an inattentive master to lame a camel, and a lame camel was a dead camel, a communal feast. In that way, Allah provided for them all. It was his will, and there was no compensation for the camel’s owner in this world. “We only feed you for Allah’s sake,” says the Quran. “We desire from you neither reward nor thanks.”
On the seventh day, the irifi roared in from the southeast, and the sand swirled. Sidi Ishrel ordered the camels to be unloaded and camp made. In a hurry, the Arabs stacked their goods—iron, lumber, amber, shotguns, knives, scimitars, bundles of haiks, white cloth and blue cloth, blocks of salt, sacks of tobacco and spices—in a great pile. They circled up the camels and made them lie down.
All around them the sand blew so hard that the men could not open their eyes, and if they did, they could not see their companions or their camels even if they were nearly touching them. It was all they could do to breathe. Lying on their stomachs, Hamet and Seid inhaled through the sheshes wrapped around their heads and across their faces, which they pressed into the sand.
They did not fear much for their camels, which have their own defenses: deep-set, hirsute ears and long eyelashes that protect against flying grit, collapsible nostrils that add moisture to the searing air they breathe, and eyes with lids so thin that they can close them during a sandstorm and still see. They did not worry about them overheating either, for camels have a unique ability to absorb heat in their bodies while their brains remain insulated and stable. They conserve their body water by not sweating or panting, instead retaining the heat during the day and releasing it later. On bitterly cold nights, their owners often took refuge in their warmth. As all good cameleers knew, these prized beasts were as impervious to the abuse of the desert as it was possible to be, and they were as long-lived as they were ornery, some reaching half a century in age. Many would outlive their masters.
For two days, sand filled their long-sleeved, hooded wool djellabas and formed piles on their backs until they shifted to ease the weight. Hamet and Seid and the rest of the traders and cameleers beseeched, “Great and merciful Allah, spare our lives!” When the wind at last halted and the sand fell to the ground, three hundred men lay dead on the desert. Hamet and Seid, who were strong, rose and joined the rest of the survivors in prayers of thanksgiving to Allah for saving them. They spent two more days burying the dead men, always on their sides, facing east toward Mecca, and topping their graves with thorny brush to keep the jackals away. All but two hundred of the camels had been spared. As the men dug them out, the beasts rose, grunting and snapping madly, weak-kneed, snorting out the beetlelike parasites that grew in their nostrils. There were no plants for the camels to eat where they had stopped, so the men watered and fed them from the dwindling provisions.
