the ramp, to the slab of desert that lifted on pneumatic hinges to admit scalding floods of light and to reveal again the shimmering horizons of our journey. The Hulul Depression, its gravels and crusty sands ruddy in color, as if the rivers that had long ago emptied into this cracked lakebed had been tinged with blood, gave way, while the sun climbed toward its incandescent apogee, to the foothills of the Bulub Mountains. The piste diminished to a winding track, treacherously pitted and strewn with a flinty scrabble that well challenged the mettle of our Michelin steel-belted radials. The distances became bluish; as we rose higher, clots of vegetation, thorny and leafless, troubled the rocks with their grasping roots. In the declivities that interrupted our grinding, twisting ascent, there were signs of pasturage: clay trampled to a hardened slurry by hooves, excrement still distinguishable from mineral matter, some toppled skeletons of beehive huts, their thatch consumed as a desperate fodder. Aristada, which thrives on overgrazed lands, tinged with green this edge of desolation. Our route went not directly across the Bulubs, but along their shoulder; to the east the horizon was low, though undulating, and the smoke of a nomadic encampment, of Teda or the dreaded Tuareg, manifested itself to the keen eyes of my companions. I, in seeking to verify their glimpse of potentially sinister smoke, seemed to see an altogether different apparition: two golden parabolas showed above a distant deckled ridge and, as I gazed incredulously, slowly sank from sight, the motion of the car carrying us behind an escarpment. Neither Mtesa nor Opuku could confirm my sighting, though we halted the car and prowled the searing terrain for a vantage. The rocks here held iridescent streaks of strange sleek minerals. Having halted, we performed our salat az-zuhr and fell asleep in the shade of a ledge, where lizards came to skitter across us as if our dozing bodies had joined the vast insensate chorus of changeless stone, the touch of their feet daintier than the first tingling drops of a rain. The days of the journey merge in my memory after that poisonous glimpse of golden parabolas; a sort of delirium of distance overtook us. We traversed many sorts of naked soil-flinty orange gorges, black clay where slatelike slabs had been set with the regularity of a demented divine masonry, stretches of purple gravel varied by shifting hillocks of amber sand. In the wide belt of transition between withered sudan and stark desert, there were islands of what had been, before the drought, pasture land, whose inhabitants, human and animal, had been stranded by the rising sea of dearth. We saw strange sights; we saw naked women climbing mimosa trees to crop the twig-tips for cooking, we saw children gathering the wild nettle called cram-cram, we saw men attacking and pulverizing anthills to recover the crumbs of grain that had been stored there. Even the most brackish water holes had been drunk dry, and the trees rimming them reduced to stumps stripped of bark by savage hunger. My hand grows too heavy to write as I remember this misery. iMost grotesquely, the sun each day beat upon these scenes with the serene fury of an orator who does not know he has made exactly the same points in a speech delivered the day before. As we neared our destination on the northwest border, and the population thickened in consequence of the rumored excitement there, I abandoned the Mercedes and assumed the wool rags of a Sufi, the better to mingle with my people in their suffering. A party of itinerant well-diggers took me up, to bring them luck. In truth, they had need of it-a party of four, two male Moundangs, a Galla dwarf, and a Sara woman who cooked and serviced us all. The leader, Wadal, a tall morose man whose lassitudinous brown length seemed an enlarged analogue of his impotent penis, which he kept morosely displaying through the rents in his tattered galabieh, had no nose
