Noise enters largely into street life, and the native is invariably loud voiced. No bargain is concluded without an apparent squabble, and every tradesman in the street calls his wares, while drivers of vehicles are incessant in their cries of warning to foot-passengers. All the sounds are not unmusical, however, for from the minarets comes the "muezzin's" sweet call to prayer, to mingle with the jingling bells and the tinkling of the cups of the water-sellers. Then the donkey-boys, everywhere to be found in Cairo, add much to the liveliness of the streets. Their donkeys are fine animals, usually grey and very large, and their bodies are shaved in such a manner as to leave patterns on the legs and snout, which are often coloured. The saddles are of red leather and cloth, and from them hang long tassels which swing as they canter through the streets, while the musical rattle of coloured beads and the chains of copper and brass which all donkeys wear around their necks, add their quota to the many noises of the streets, through which in a low murmur one may distinguish the drone of flies. Among all the bustle and confusion, shimmering lights, and varied colour which constitute a Cairo street scene, the native woman passes with graceful dignity. Her features are hidden by the "bourka," or veil, which is generally worn, but her beautiful eyes fascinate; nor does the voluminous cloak she wears entirely conceal the dainty, if brilliant, clothing beneath, nor the extreme beauty of her well-shaped hands and feet. Quite as picturesque as the life of the streets are the buildings which enclose them, and the great glory of Cairo consists of its bazaars and mosques and old-time palaces. The streets are usually irregular in width and often winding, and are sometimes so narrow as to render driving impossible, for when Cairo was built wheeled vehicles were not in use, and space within its walls was limited. The houses are very lofty, and are built of limestone or rubble covered with white plaster, and the lower courses are often coloured in stripes of yellow, white, and red. Handsome carved doorways open from the street, and the doors are panelled in bold arabesque design, or enriched by metal studs and knockers of bronze. The windows on the ground-floor, which are usually small, are closed by a wooden or iron grating, and are placed too high in the wall for passengers to look through them, and frequently, even in the best houses, small recesses in the walls serve as shops. The upper storeys usually project beyond the ground-floor, and are supported on corbels or brackets of stone, which also are frequently carved. This method of building has two advantages, for the projecting upper storeys afford a little shade in the streets, and at the same time give greater space to the houses without encroaching upon the already narrow thoroughfares.
