But after a time this holiday journey is interrupted. A fearful change takes place. The careless waters are hurried down a long and sharp descent, over the rough, denuded, bowlder-studded bed-rock of the stream. Breaking and bounding, surging and resurging, flashing and foaming, rushing fiercely upon some huge bowlder, recoiling an instant, then madly leaping entirely over it, rushing on to others huger still, then breaking wildly around them, the troubled waters hurry on until, culminating in their sublimest aspect, they plunge sheer downward in the grandest of cataracts. And now the scene and the effect it produces on the beholder both change. The rapids are beautiful; the falls are grand; those are exhilarating, these are inspiring; those are noisy, turbulent, fickle; these are calm, resistless, inexorable. After the water has made the final plunge over the precipice the cataract acquires its most impressive characteristics; the majestic monotone, the bow, the cloud, which is its veil by night, its crowning glory and beauty by day. The combinations of grandeur and beauty have reached their climax in the fall, the foam, the voice, the spray, the bow. [Illustration: THE RAPIDS ABOVE THE FALLS] The chasm of the river from the Falls to Lewiston will be sufficiently described in treating of the geology of the district. From Lewiston to Lake Ontario, seven miles, the waters of the river flow on through an elevated and fertile plain, in a strong, calm, majestic current, smiling with dimples and reversed in occasional eddies, but neither broken by rapids nor impeded by islands. Finally it is lost in the lake, after passing an immense bar formed by the enormous mass of sedimentary matter carried down by its own current. The landscape, as seen from the top of the terrace above Lewiston, is one of the finest and most extensive of its peculiar character which can be found on the continent, all its features being such as appertain to a broad, open country. The visitor at Niagara, as he looks at the Falls, will have a profounder appreciation of their magnitude by considering that it requires the water drainage of a quarter of a continent to sustain them, and that the remoter springs, which send to them their constant tribute, are more than twelve hundred miles distant.
