The sun shone brightly. All over the fields and fallow ground that lay between the halting-place just described, and the foot of the steep mount, the visitors were scattered--pedestrians, with here and there a horseman; sight-seers--the old and the young--men of science from various parts of the world--infantry soldiers, sappers and miners, ladies and gentlemen, sailors, marines, country people, railway laborers, policemen, boys and girls, and--far in the rear of all, with disapproving looks--two or three old women in spectacles. Renovated by his gingerbread and apples, Sir Valentine made his way manfully up the steep grassy ascent of the hill, chalk mountain it might be more properly termed, and, in the course of a quarter of an hour, he found himself at the spot where the explosion was to take place. It was a tolerably level surface, of some hundred yards in diameter. Transverse belts of excavated chalk, with several trenches and pits half filled up, marked out the huge fragment of the solid mass which was to be separated. The boundary was further indicated by small flagstaffs, and also by sentinels, who prevented any of the visitors from trespassing on the dangerous ground, whereon, of course, they all had a half-delightful tingling wish to perambulate, and to feel themselves liable to be blown to atoms by a premature explosion. Beneath the part marked off by the flagstaffs and sentinels, at a great depth in the chalk rock, were buried many thousand (the Brighton Herald said twenty-seven thousand!) pounds of gunpowder, distributed in different chambers and galleries, one communicating with another by means of a platina wire. This wire was carried up through the rock into a little wooden house, in which certain chemical mysteries were being secretly carried on by engineer officers. There was a little window in front, out of which the mysterious officer now and then half thrust his head, looked out, with profound gravity, upon the belts of chalk on the space before him, and, without appearing to see any of the crowding visitors, withdrew from the window. Presently another officer came, and did the same. "Come like shadows," muttered Sir Valentine, "so depart!"
