Over the river, so still with its oily eddies and delicate wreaths of foam, just below the Falls they have in late years woven a web of wire high in air, and hung a bridge from precipice to precipice. Of all the bridges made with hands it seems the lightest, most ethereal; it is ideally graceful, and droops from its slight towers like a garland. It is worthy to command, as it does, the whole grandeur of Niagara, and to show the traveller the vast spectacle, from the beginning of the American Fall to the farthest limit of the Horse-Shoe, with all the awful pomp of the rapids, the solemn darkness of the wooded islands, the mystery of the vaporous gulf, the indomitable wildness of the shores, as far as the eye can reach up or down the fatal stream. To this bridge our friends now repaired, by a path that led through another of those groves which keep the village back from the shores of the river on the American side, and greatly help the sight-seer's pleasure in the place. The exquisite structure, which sways so tremulously from its towers, and seems to lay so slight a hold on earth where its cables sink into the ground, is to other bridges what the blood horse is to the common breed of roadsters; and now they felt its sensitive nerves quiver under them and sympathetically through them as they advanced farther and farther toward the centre. Perhaps their sympathy with the bridge's trepidation was too great for unalloyed delight, and yet the thrill was a glorious one, to be known only there; and afterwards, at least, they would not have had their airy path seem more secure.
