pedal when he was still a couple of hundred feet away; and at long last he switched off the jeep’s laboring engine.
    The shrill whine of the generator blessedly squeaked to a halt, but in the sudden desert silence he felt even more conspicuous. He climbed stiffly out of the driver’s seat and plodded around to the back, and as he unstrapped his two cases he squinted over his shoulder at the campfire and the tents and the humps of camels grazing beyond, and his nostrils flared at the warm aroma of boiled rice and butter on the alkali breeze.
    The three men by the fire had stood up when the engine died, and Hale straightened the dusty kaffiyeh on his head and then hefted his cases and stepped away from the jeep. In spite of the head-cloth’s protection and the cloudy sky throughout the long day, he could feel the sting of sunburn on his nose and forehead.
    He trudged slowly across the gravel to the fires, noting that the camels had already been watered—the nearest well mound had been cleared of sand and its cover of lumber and skins had been pulled away, to be conscientiously replaced before leaving tomorrow morning, and the mound, a cement of sand and a hundred years of accumulated camel dung, glinted with muddy moisture in the firelight.
    “Al Kuwa,” he called. God give you strength. These men knew he was English—a Frank, a nominal Christian, a Nazrani —but he wanted to say nothing to emphasize it.
    “Allah-i-gauik,” the three of them replied, civilly enough. God strengthen you.
    “You camp right at the well?” Hale went on in Arabic when he had laid down his cases and embraced bin Jalawi. From one of the other men he accepted a small cup of hot coffee made from the well water, and drank it—it tasted fresh, but he knew that a laboratory analysis would show high concentrations of albuminoid ammonia, indicating contamination of camel urine in the well water.
    “We are on the border of the desolation of A’ad,” said the man who had handed Hale the cup. He was a lean, black-haired ’Al-Murra tribesman with a leather cartridge belt over his shoulder and what looked like an old single-shot .450 rifle propped against a camel saddle beside him. “Even the Saar tribes will have the sense to stay out of the Rub’ al-Khali in these nights.” He laughed quietly.
    “Or even in the days,” said bin Jalawi helpfully, crouching to sit by the fire again. “Men’s hopes are confounded when angels bend their courses down to earth.” Squinting up at Hale, he said, “I’ll wager the dibba came to Hufuf, after we left?”
    “Yes,” Hale admitted. Dibba was the Arab term for locusts in the wingless, crawling stage, and armies of them often followed the airborne migrations. “Nothing extraordinary.” In fact the dibba had advanced on Hufuf from out of the southern desert in a front four miles wide and two miles deep, and black masses of them had stripped the date trees so bare that they appeared to have been burned. When Hale had driven out of town at dawn, he had seemed to be driving over crunching black snow, and on the road he had seen half a dozen dog-sized monitor lizards springing up in the chilly air to catch strays from the low-flying last wave of winged locusts.
    “ ‘Nothing extraordinary,’ ” echoed bin Jalawi in a thoughtful tone, and the other two Bedu muttered to each other as they spread their robes and sat down. “Perhaps to the Franks the end of the world is nothing extraordinary.”
    Hale found a place to sit on the windward side of the fire, and he accepted a plate of rice ladled from the pan that would recently have served as the camels’ drinking trough. He dug in hungrily with his right hand, licking his fingers, for he had brought only bread and cheese to sustain him during the day’s jolting drive.
    “A few million bugs don’t make the end of the world,” he said to bin Jalawi around a mouthful of rice.
    “It is metaphorical,” said bin Jalawi, using the English word.
    In the twilight Hale could see several of the ruined forts of ancient Jabrin silhouetted against the purple sky. He knew that Jabrin had been a prosperous city long ago and that at some point the citizens had been driven out into the desert by a killing fever; the illness had abided at the place like a curse, and struck all the Arabs who had periodically made the attempt to live here since then. Oddly, travelers who stopped at the oasis never contracted the malady, and now the Bedu visited Jabrin only
