Above the palm trees swept the jewelled vault of Egypt's sky, and set amid the clustering leaves gleamed little red electric lamps; fairy lanterns outlined the winding paths and paper Japanese lamps hung dancing in long rows, whilst in the centre of the enchanted garden a fountain spurned diamond spray high in the air, to fall back coolly plashing into the marble home of the golden carp. The rustling of innumerable feet upon the sandy pathway and the ceaseless murmur of voices, with pealing laughter rising above all, could be heard amid the strains of the military band ensconced in a flower-covered arbour.  
Into the brightly lighted places and back into the luminous shadows came and went fantastic forms. Sheikhs there were with flowing robes, dragomans who spoke no Arabic, Sultans and priests of Ancient Egypt, going arm-in-arm. Dancing girls of old Thebes, and harem ladies in silken trousers and high-heeled red shoes. Queens of Babylon and Cleopatras, many Geishas and desert Gypsies mingled, specks in a giant kaleidoscope. The thick carpet of confetti rustled to the tread; girls ran screaming before those who pursued them armed with handfuls of the tiny paper disks. Pipers of a Highland regiment marched piping through the throng, their Scottish kilts seeming wildly incongruous amid such a scene. Within the hotel, where the mosque lanterns glowed, one might catch a glimpse of the heads of dancers gliding shadowlike.
 
"A tremendous crowd," said Sime, "considering it is nearly the end of the season."
 
Three silken ladies wearing gauzy white yashmaks confronted Cairn and the speaker. A gleaming of jewelled fingers there was and Cairn found himself

half-choked with confetti, which filled his eyes, his nose, his ears, and of which quite a liberal amount found access to his mouth. The three ladies of the yashmak ran screaming from their vengeance-seeking victims, Sime pursuing two, and Cairn hard upon the heels of the third. Amid this scene of riotous carnival all else was forgotten, and only the madness, the infectious madness of the night, claimed his mind. In and out of the strangely attired groups darted his agile quarry, all but captured a score of times, but always eluding him.
 
Sime he had hopelessly lost, as around fountain and flower-bed, arbour and palm trunk he leapt in pursuit of the elusive yashmak.
 
Then, in a shadowed corner of the garden, he trapped her. Plunging his hand into the bag of confetti, which he carried, he leapt, exulting, to his revenge: when a sudden gust of wind passed sibilantly through the palm tops, and glancing upward, Cairn saw that the blue sky was overcast and the stars gleaming dimly, as through a veil. That moment of hesitancy proved fatal to his project, for with a little excited scream the girl dived under his outstretched arm and fled back towards the fountain. He turned to pursue again, when a second puff of wind, stronger than the first, set waving the palm fronds and showered dry leaves upon the confetti carpet of the garden. The band played loudly, the murmur of conversation rose to something like a roar, but above it whistled the increasing breeze, and there was a sort of grittiness in the air.
 
Then, proclaimed by a furious lashing of the fronds above, burst the wind in all its fury. It seemed to beat down into the garden in waves of heat. Huge leaves began to fall from the tree tops and the mast-like trunks bent before the fury from the desert. The atmosphere grew hazy with impalpable dust; and the stars were wholly obscured.
