The landscape on either side of the falls has little of the picturesque or tumultuous about it, being generally slightly rolling, and giving no indication of eruptive disturbance; so that scientists are still searching for a plausible theory upon which to base a conclusion as to the cause that produced this sudden dip in the limestone formation. The astounding power displayed by the river dropping over a wide and lofty ledge is scarcely more bewildering than that exhibited by the Rapids, which extend for half a mile from the point of descent, and meeting a swift current, the flood is lashed into a fury that is frightful to behold, rising in the center like huge beasts in combat, and tossing wave-caps nearly fifty feet above the surface. At times the spray rises in such clouds as to completely obscure the falls, and borne some distance by the winds is condensed, and a long-continued rain follows, which renders a considerable stay in the neighborhood somewhat disagreeable.

Nature, aided by the embellishments of art, has made the place an exceedingly attractive resort, which grows in favor with each passing year. No imaginary picture, be it ever so attractive, could surpass in picturesqueness the scene so beautifully photographed on this page. ] ------------------------------------------------------------------------ [Illustration: AMERICAN FALLS, VIEWED FROM GOAT ISLAND.]
