blackened by sun and rain, cropped out of the ground. At half-past ten
we

[p.69] found ourselves in an “Acacia-barren,” one of the things which
pilgrims dread. Here Shugdufs are bodily pulled off the camel’s back and
broken upon the hard ground; the animals drop upon their knees, the
whole line is deranged, and every one, losing temper, attacks his
Moslem brother. The road was flanked on the left by an iron wall of
black basalt. Noon brought us to another ridge, whence we descended
into a second wooded basin surrounded by hills.

Here the air was filled with those pillars of sand so graphically
described by Abyssinian Bruce. They scudded on the wings of the
whirlwind over the plain,—huge yellow shafts, with lofty heads,
horizontally bent backwards, in the form of clouds; and on more than
one occasion camels were thrown down by them. It required little
stretch of fancy to enter into the Arabs’ superstition. These
sand-columns are supposed to be Jinnis of the Waste, which cannot be
caught, a notion arising from the fitful movements of the electrical
wind-eddy that raises them, and as they advance, the pious Moslem
stretches out his finger, exclaiming, “Iron! O thou ill-omened one[FN#15]!”

During the forenoon we were troubled by the Samum, which, instead of
promoting perspiration, chokes up and hardens the skin. The Arabs
complain greatly of its violence on this line of road. Here I first
remarked the difficulty with which the Badawin bear thirst. Ya Latif,—“O
Merciful!” (Lord),—they exclaimed at times; and yet they behaved like
men.[FN#16] I had ordered them to place the

[p.70] water-camel in front, so as to exercise due supervision. Shaykh
