Isabel gave a little start, as if she had almost thought of something she was trying to think of.
They occasionally met ladies driving, and sometimes they encountered a couple making a tour of the island on foot.

But none of these people were young, and Basil reported that the Three Sisters were inhabited only by persons of like maturity; even a group of people who were eating lunch to the music of the shouting Rapids, on the outer edge of the last Sister, were no younger, apparently.
Isabel did not get out of the carriage to verify his report; she preferred to refute his story of her former panic on those islands by remaining serenely seated while he visited them.

She thus lost a superb novelty which nature has lately added to the wonders of this Fall, in that place at the edge of the great Horse Shoe where the rock has fallen and left a peculiarly shaped chasm: through this the spray leaps up from below, and flashes a hundred feet into the air, in rocket-like jets and points, and then breaks and dissolves away in the pyrotechnic curves of a perpetual Fourth of July.

Basil said something like this in celebrating the display, with the purpose of rendering her loss more poignant; but she replied, with tranquil piety, that she would rather keep her Niagara unchanged; and she declared that, as she understood him, there must be something rather cheap and conscious in the new feature.

She approved, however, of the change that had removed that foolish little Terrapin Tower from the brink on which it stood, and she confessed that she could have enjoyed a little variety in the stories the driver told them of the Indian burial-ground on the island: they were exactly the stories she and Basil had heard twelve years before, and the ill-starred goats, from which the island took its name, perished once more in his narrative.
Under the influence of his romances our travelers began to find the whole scene hackneyed; and they were glad to part from him a little sooner than they had bargained to do.
