Fountains in the Sand by Norman Douglas — Read

A person unacquainted with tropical vegetation would be amazed at the prodigality of the oasis of Nefta; in point of exuberance it is as superior to Tozeur as that to Gafsa. But the cathedral-like gravity of Tozeur is lacking; there is too much riot and opulence, too many voluptuous festoons and spears and spirals, a certain craving, so to speak, after the purely ornate: if Tozeur represents the decorative style of Louis Quatorze, this is assuredly Louis Seize. One great drawback is that the thick undergrowth often obstructs the view; and another, that you cannot walk about in all directions, as at Tozeur, because there is too much running water -- perhaps one should say too few paths and bridges. For the last two days a sand-storm of unusual violence has been raging. On the ridges above the town one can hardly stand on one's feet; the grains fly upwards, over the crest of the hill, in blinding showers, mighty squadrons of them careering across the plain below.

The landscape is involved in a dim, roseate twilight. But occasionally there comes a sickly radiance from behind the curtain of cloud that glimmers lustreless, like an incandescent lamp seen through a fog: it is the sun shining brightly in the pure regions of the upper air.
