From the upper point of Goat Island a bar stretches up the river, and can be plainly seen dividing the rapids which pass on either side to the American and Canadian falls. A foot-bridge from Goat Island, on the American side, leads to the pretty little Luna Island, standing at the brink of the cataract and dividing its waters. The narrow channel between makes a miniature waterfall, under which is the famous "Cave of the Winds." Here the venturesome visitor goes actually under Niagara, for the space behind the waterfall is hollowed out of the rocks, and amid the rushing winds and spray an idea can be got of the effects produced by the greater cataracts. Here are seen the rainbows formed by the sunlight on the spray in complete circles; and the cave, one hundred feet high, and recessed into the wall of the cliff, gives an excellent exhibition of the undermining processes constantly going on. Upon the Canadian side of Goat Island, at the edge of the fall, foot-bridges lead over the water-worn and honeycombed rocks to the brink of the great Horseshoe. Amid an almost deafening roar, with rushing waters on either hand, there can be got in this place probably the best near view of the greater cataract. Here are the Terrapin Rocks, and over on the Canadian side, at the base of the chasm, are the fragments of Table Rock and adjacent rocks which have recently fallen, with enormous masses of water beating upon them. In the midst of the rapids on the Canadian side of Goat Island are also the pretty little islands known as the "Three Sisters" and their diminutive "Little Brother," with cascades pouring over the ledges between them--a charming sight. The steep descent of the rapids can here be realized, the torrent plunging down from far above one's head, and rushing over the falls. This fascinating yet precarious region has seen terrible disasters and narrow escapes. The overpowering view of all, from Goat Island, is the vast mass of water pouring down the Canadian falls. This is fully twenty feet in depth at the brink of the cataract, and it tumbles from all around the deeply recessed Horseshoe into an apparently bottomless pool, no one yet having been able to sound its depth. In 1828 the "Michigan," a condemned ship from Lake Erie, was sent over this fall, large crowds watching. She drew eighteen feet water and passed clear of the top. Among other things on her deck were a black bear and a wooden statue of General Andrew Jackson. The wise bear deserted the ship in the midst of the rapids and swam ashore. The ship was smashed to pieces by the fall, but the first article seen after the plunge was the statue of "Old Hickory," popping headforemost up through the waters unharmed. This was considered a favorable omen, for in the autumn he was elected President of the United States. THE RAPIDS AND THE WHIRLPOOL.
