She looked at him as if she had made the most satisfying statement, and he thought he had better not ask further then, but wait in hope that the meaning would come to him. They walked on in silence till they came to the Biddle Stairs, at the head of which is a notice that persons have been killed by pieces of rock from the precipice overhanging the shore below, and warning people that they descend at their peril. Isabel declined to visit the Cave of the Winds, to which these stairs lead, but was willing to risk the ascent of Terrapin Tower. “Thanks; no,” said her husband. “You might find it unsafe to come back the way you went up. We can't count certainly upon the appearance of the lady who is so much like you; and I've no fancy for spending my life on Terrapin Tower.” So he found her a seat, and went alone to the top of the audacious little structure standing on the verge of the cataract, between the smooth curve of the Horse-Shoe and the sculptured front of the Central Fall, with the stormy sea of the Rapids behind, and the river, dim seen through the mists, crawling away between its lofty bluffs before. He knew again the awful delight with which so long ago he had watched the changes in the beauty of the Canadian Fall as it hung a mass of translucent green from the brink, and a pearly white seemed to crawl up from the abyss, and penetrate all its substance to the very crest, and then suddenly vanished from it, and perpetually renewed the same effect. The mystery of the rising vapors veiled the gulf into which the cataract swooped; the sun shone, and a rainbow dreamed upon them. Near the foot of the tower, some loose rocks extend quite to the verge, and here Basil saw an elderly gentleman skipping from one slippery stone to another, and looking down from time to time into the abyss, who, when he had amused himself long enough in this way, clambered up on the plank bridge. Basil, who had descended by this time, made bold to say that he thought the diversion an odd one and rather dangerous. The gentleman took this in good part, and owned it might seem so, but added that a distinguished phrenologist had examined his head, and told him he had equilibrium so large that he could go anywhere. “On your bridal tour, I presume,” he continued, as they approached the bench where Basil had left Isabel. She had now the company of a plain, middle-aged woman, whose attire hesitatingly expressed some inward festivity, and had a certain reluctant fashionableness. “Well, this is my third bridal tour to Niagara, and my wife's been here once before on the same business. We see a good many changes. I used to stand on Table Rock with the others. Now that's all gone. Well, old lady, shall we move on?” he asked; and this bridal pair passed up the path, attended, haply, by the guardian spirits of those who gave the place so many sad yet pleasing associations.
