I thought I could make out, too, the gloomy opening's of great galleries leading into the principal room. It looked like a subterranean town with streets and squares. I stopped short, deeming it dangerous to venture alone into that vast labyrinth. Suddenly one of the galleries below me was lit up brilliantly, and I saw a great number of torches, which appeared to come out of the sides of the rocks as though they formed a great procession. At the same time a monotonous chanting rose up, which recalled the singing of the Arabs as they recited their prayers. Soon I could distinguish a vast multitude advancing slowly. At their head stepped a black man, almost naked, his head covered with an enormous mass of stubbly hair. His white beard fell on his breast, and contrasted with the brown colour of his chest, which was gashed with bluish-tinted tattooing. I quickly recognised the sorcerer of the previous evening, and, soon after, saw the little girl near him who had played the part of Eurydice, with her fine eyes, and her silk pantaloons, and the embroidered handkerchief on her head. Women and children and men of all ages followed them, all holding torches, all dressed in strange costumes of vivid colour, with trailing skirts and high caps, some made of metal, which reflected the light from the torches on all sides. The old sorcerer stopped exactly below me, and the whole procession with him. The silence was profound. I was twenty feet above him, protected by great stones, from behind which I hoped to see everything without being perceived. At the feet of the old man I noticed a large slab of stone, almost round, with an iron ring in the centre. He pronounced some words in a tongue unknown to me, which I felt sure was neither Arabic nor Kabylic. A rope and pulleys, hung from somewhere, fell at his feet; several of the assistants attached it to the ring, and at a given signal twenty stalwart arms all pulled at the stone simultaneously. It seemed of great weight, but they raised it and put it to one side. I then saw what looked like the opening down a well, the water of which was at least a yard from the top. Water, did I say? I do not know what the frightful liquid was; it was covered over with an iridescent film, disturbed and broken in places, and showing a hideous black mud beneath. The sorcerer stood in the midst of the gathered crowd, near the kerbstone which surrounded the well, his left hand on the little girl's head; with his right he made strange gestures, whilst uttering a kind of incantation.
