I had been in and out of Constantinople a good many years before I even heard of the Sacred Caravan. The first I heard of it then was on the Bridge one day, when I became aware of a drum beating out a curious slow rhythm: _one_, two, _three_, _four_, five, six; _one_, two, _three_, _four_, five, six. I waited to see what would happen, and presently from the direction of Stamboul straggled a procession that, of course, I had no camera to photograph, against the grey dome and springing minarets of Yeni Jami. It was led by two men with tom-toms beating in unison the rhythm I had heard. I later learned that those tom-toms have a special name, _kyöz_. After the drummers marched a number of boys in pairs, carrying small furled flags of red silk embroidered with gold. Behind the boys strode a serious-looking person who held a small round shield and a drawn sword. He was followed by a man bearing a big green standard, embroidered and fringed with gold, on a white staff tipped by a sort of brass lyre in which were Arabic letters. Next came a palanquin of white wood slung between mules. It had glass windows and wooden shutters, and looked very cosy with its red silk cushions; but nobody was there to enjoy them. In the rear of the palanquin were men carrying staves with bunches of dyed ostrich feathers at their tips, like enormous dusters. And then slouched along a magnificent camel. He wore a green silk saddle-cloth embroidered in white, and above that a tall green silk hoodah with gold embroidery; and ostrich plumes nodded from him in tufts, and at his knees he wore caps of coloured beads. Behind him trotted a lot of mules in pairs, all loaded with small hair trunks. I did not know that the trunks were full of presents for the good people of Mecca and Medina.
