Neither Baron La Hontan nor M. Charlevoix speaks of the number of water-falls. But Father Hennepin, it will be remembered, mentions three, two of which were to the south and west of Goat Island. And the Rev. Abbé Picquet, who visited the place in 1751, seventy years after Father Hennepin, says (Documentary History, I., p. 283): "This cascade is as prodigious by reason of its height and the quantity of water which falls there, as on account of the variety of its falls, which are to the number of six principal ones divided by a small island, leaving three to the north and three to the south. They produce of themselves a singular symmetry and wonderful effect." [Illustration: LUNA FALL AND ISLAND IN WINTER] The geological indications are that Goat Island once embraced all the small islands lying near it, and also that it covered the whole of the rocky bar which stretches up stream some hundred and fifty rods above the head of the present island. At that period, from the depressions now visible in the rocky bed of the river, it would seem probable that the water cut channels through the modern drift corresponding with these depressions. In that case there would then have been a third fall in the American channel, north of Goat Island, lying between Luna Island and a small island then lying just north of the Little Horseshoe, and stretching up toward Chapin's Island. On the south side of Goat Island, there would have been a fall between its southern shore and an island then situated about two hundred feet farther south. The highest point in the American Fall, the salient and beautiful projection near the shore at Prospect Park, is upheld by a more substantial foundation than is revealed at any other accessible portion of the face of the precipice. This is made manifest on entering the "Shadow-of-the-Rock," where the spectator sees a massive wall of thoroughly indurated limestone, disposed in regular layers more than two feet in thickness, with faces as smooth as if dressed with the chisel. Passing in front of this, across the American Fall, under the Horseshoe and Table Rock, there must have been formerly a broad cleft of soft, friable limestone, to the disintegration and removal of which was due the great overhanging of the upper strata noticed by Father Hennepin and Baron La Hontan. For three miles above the Falls, the course of the river is almost due west. But after leaving the precipice it makes an acute angle with its former direction, and thence runs north-east to the railway suspension bridge. The formation of the rapids--one of the most beautiful features of the scene--is due to this change of direction. At no point below its present position could there have been such a prelude--musical as well as motional--to the great cataract. And when these rapids shall have disappeared in the receding flood it is not probable that there will be other rapids that can equal them in length, breadth, beauty, and power.
