It was a hot July day and, during the noon pause, the vendors of cooling drinks did a good business among the spectators of the upper tiers. To the ring-rope round the opening in the awning, over the middle of the arena, had been fastened a big, strong, pulley block. One of the lightest and most agile of the awning-boys hung by his hands from the radial rope stretched from nearest that pulley, worked out to it, sat on it, rove through it a light cord which he carried coiled at his waist, and worked back along the radial rope, leaving the cord trailing from the pulley- wheel to the sand of the arena. By means of the cord the arena-slaves rove through the pulley first a light rope, then a very strong one. The end of this rope they fastened to an iron ring, from which hung four stout chains, three of them of equal length, each about thirty feet, whose lower ends, at points precisely equidistant from each other, were fastened to a big iron hoop all of twenty-four feet across. From the hoop hung six lighter chains, like the fourth chain which hung from the ring. As the six were fastened to the hoop either where one of the upper chains ended or exactly between two of them each of the six was precisely twelve feet from those on either side of it and from the center chain hanging from the ring. The hoop hung perfectly level and each of the seven chains, about thirty feet below the level of the hoop, had hung to it an iron disk, a yard or more across, hanging by a ring-bolt in its center and perfectly level. From a second ring-bolt in the underside of each disk depended more of the same light, strong chain, to a length of some thirty feet below the disks. I, like all the arena-slaves and Choragium-slaves, like all the spectators, knew that this apparatus portended some unpredictable surprise; but I, like the others, like the audience, gaped at it, incredulous and unable to conjecture what it could be for. Then arena-slaves carried in and set down on the sand a full hundred feet from the hoop and chains, a dozen or more wicker crates full of quacking white ducks with yellow bills. They and the noise they made recalled unpleasantly to me my sensations as I clung to the alder bush immersed in Bran Brook, after Agathemer and I had crawled through the drain at Villa Andivia. Then there was a delay and I was called out to assist the mahout of the Choragium's best trick elephant, the smallest full-grown elephant I ever saw and the worst-dispositioned elephant of any age or size which ever I encountered. When I and the _mahout_ had put him in a good humor he entered the arena and stationed himself by the crates of quacking ducks. Then there marched out into the arena a procession of arena-slaves, four by four, each four carrying by two poles a strong cage housing a big African ape. These cages they set down each under one of the chains depending from the hoop. Then I was called to deal with the baboons.
