That is what happened at this dinner. As soon as you had started a nice conversation with a lady a sort of roaring was heard without; her eyes gleamed, her nostrils quivered like a horse planning a gallop, and in the middle of one of your best sentences she simply faded away with some horrible man at the other end of the table who was probably "the only man in London who can do the Double Straddle properly." This went on the whole of the meal, and it made connected conversation quite difficult. For my own part I went on eating, and when I had properly digested I went out and looked at the little victims getting their money's worth. From the door of the room where the dancing was done a confused uproar overflowed, as if several men of powerful physique were banging a number of pokers against a number of saucepans, and blowing whistles, and occasional catcalls, and now and then beating a drum and several sets of huge cymbals, and ceaselessly twanging at innumerable banjoes, and at the same time singing in a foreign language, and shouting curses or exhortations or street cries, or imitating hunting-calls and the cry of the hyena, or uniting suddenly in the war-whoop of some pitiless Sudan tribe. It was a really terrible noise. It hit you like the back-blast of an explosion as you entered the room. There was no distinguishable tune. It was simply an enormous noise. But there was a kind of savage rhythm about it which made one think immediately of Indians and fierce men and the native camps one used to visit at the Earl's Court Exhibition. And this was not surprising. For the musicians included one genuine negro and three men with their faces blacked; and the noise and the rhythm were the authentic music of a negro village in South America, and the words which some genius had once set to the noise were an exhortation to go to the place where the negroes dwelt. To judge by their movements, many of the dancers had in fact been there, and had carefully studied the best indigenous models. They were doing some quite extraordinary things. No two couples were doing quite the same thing for more than a few seconds, so that there was an endless variety of extraordinary postures. Some of them shuffled secretly along the edge of the room, their faces tense, their shoulders swaying like reeds in a light wind, their progress almost imperceptible; they did not rotate, they did not speak, but sometimes the tremor of a skirt or the slight stirring of a patent-leather shoe showed that they were indeed alive and in motion, though that motion was as the motion of a glacier, not to be measured in minutes or yards.
