Once a year, in February, Biskra becomes really and excessively excited, and the occasion is its annual two-day race-meeting. Then the tribes and their chieftains and their horses and their camels arrive magically out of the four corners of the desert and fill the oasis. And the English, French, and Germans arrive from the Mediterranean coast, with their trunks and their civilisation, and crowd the hotels till beds in Biskra are precious beyond rubies. And under the tropical sun, East and West meet magnificently in the afternoon on the racecourse to the north of the European reserve. And the tribesmen, their scraggy steeds trailing superb horsecloths, are arranged in hundreds behind the motor-cars and landaus, with the pari-mutuel in full swing twenty yards away. And the dancing-girls, the renowned Ouled-Nails, covered with gold coins and with muslin in high, crude, violent purples, greens, vermilions, shriek and whinny on their benches just opposite the grand stand, where the Western women, arrayed in the toilettes of Worth, Doucet, and Redfern, quiz them through their glasses. And, fringing all, is a crowd of the adventurers and rascals of two continents, the dark and the light. And in the background the palms wave eternally in the breeze. And to the east the Aur�s mountains, snow-capped, rise in hues of saffron and pale rose, like stage mountains, against the sapphire sky. And to the south a line of telegraph poles lessens and disappears over the verge into the inmost heart of the mysterious and unchangeable Sahara.
