The block of alabaster that we saw a moment ago on a boat towed by hundreds of human arms has been delivered to the sculptors and has put on, under their hands, the rough form of a mitred, human-headed bull. It will be completed after being put in place; the last touches of the chisel and the brush will then be given to it; but the heaviest part of the work is already done and the block has lost much of its original size and weight. Firmly packed with timber, the bull lies upon its side upon a sledge which is curved in front like a boat, or a modern sleigh. Two cables are fastened to its prow and two to its stern. The engineer is again seated upon the stone and claps his hands to give the time, but now he is accompanied by three soldiers who appear to support his authority by voice and gesture. In order to prevent friction and to facilitate the movement of the sledge, rollers are thrust beneath its runners as they progress. Before the huge mass will start, however, the straining cords and muscles have to be helped by a thrust from behind. This is given by means of a huge lever, upon which a number of men pull with all their weight, while its curved foot is engaged under the sledge. A workman is occupied with the reinforcement of the fulcrum by thrusting a wedge in between its upper surface and the lower edge of the lever. When everything is ready a signal will be given, the men behind will throw their weight upon the lever, the sledge will rise a little, the ropes will strain and tighten, and the heavy mass will glide forward upon the greased rollers until arms and legs give out and an interval for rest is called, to be followed presently by a repetition of the same process. Every precaution is taken to minimize the effect of any accident that may take place in the course of the operation. Behind the sledge spare ropes and levers are carried, some upon men's backs, others on small handcarts. There are also a number of workmen carrying rollers.
