The next morning Cobb and Hugh were up early, and, after a hearty breakfast, proceeded in the direction of the old inclined railways where Cobb had so often, in former years, made love and talked nonsense to the pretty girls of Niagara. A different sight met his eyes as he neared the balcony where formerly the best view of the grand falls was to be obtained. Niagara was still a mighty cataract, but not half the volume of water which had passed over its precipitous edge in former days now flowed over the walls of rock. Where formerly the great mass of surging, foamy floods rushed out over the top to a distance of fifty feet, and fell in one unbroken blue sheet into the boiling torrent below, now was a lighter sheet of white and broken water. Two artificial streams, one on either side of the river, below the falls, the beds for which had been carved out of the precipitous banks which marked the erosive power of the stream, carried an immense flow seven miles down the river. Along the banks, and from one hundred to seventy-five feet below the canals, were rows of houses of similar construction and color. From every house, in either line, poured forth a torrent of water which rushed and leaped down the rocks to the stream below. Electric wires and huge cables were to be seen in every direction. [Illustration] Turning back from the novel scene in front of him, Cobb moved nearer the edge of the balcony, and looked over towards the base of the falls. Great masses of ice rose from the depths below, half obscuring his view; but the field was clear enough for him to ascertain that a new order of phenomena had taken place since his last advent there. It seemed as if a hundred gigantic mouths in the face of the cliff were belching forth mighty torrents of seething, foamy water. Passing down the stairs to the first landing, which was sixty feet below the brink of the falls, he and Hugh came to the gate of a tunnel in the walls under the falls. The gatekeeper, after a few words from Hugh, touched an electric bell, and a young man who answered the summons was directed to show them about the works. Niagara Falls had, indeed, undergone a most remarkable change in a hundred years. The face of the cliff, from the Canadian, or "Ontario" side, as it was then termed, clear around to the city, had been pierced by huge tunnels, ten feet in diameter, extending under the rapids above for a distance of 1,000 feet. There were two rows of these tunnels; the first row was 120 feet below the top of the falls, and the tunnels were twenty feet apart. The next row was cut over the walls between the lower tunnels, and was ninety feet below the edge of the falls. Again, above this line, was a row of smaller tunnels, five feet in diameter and 100 feet apart. From the two rows of large tunnels mighty jets of water were pouring out, and breaking into foam as they reached the waters coming from over the cliff.
