In her beautiful description, given elsewhere in our story, Margaret Fuller explains the effect of the Rapids by moonlight on the heart of one who, during the day, had passed through the familiar throb of disappointment in the great spectacle at Niagara.

Now I take it one must see in Niagara this element of repose or find in it something less than was hoped for. To one who expects an ocean pouring from the moon, a rush of wind and foam like that to be met with only in the Cave of the Winds, there is bound to come that common feeling that the fact is not equal to the picture imagination had previously created. Take the Whirlpool; seen from the heights above, it

has that effect of sculpturesque repose [writes Mr. Howells], which I have always found the finest thing in the Cataract itself. From the top the circling lines of the Whirlpool seemed graven in a level of chalcedony. . . . I have no impression to impart except this sense of its worthy unity with the Cataract in what I may call its highest æsthetic quality, its repose.[8]

All this is most impressively true of the central wonder of the entire spectacle, the Falls themselves. That mighty flood of water, reborn as it dies, forms a marvellous spectacle. Writes Mrs. Schuyler Van Rensselaer:

Very soon we realise that Niagara's true effect is an effect of permanence. Many as are its variations, it never alters. It varies because light and atmosphere alter. Tremendous movement thus pauseless and unmodified gives, of course, a deeper impression of durability than the most imposing solids. . . . As soon as this fact is felt, the Falls seem to have been created as a voucher for the permanence of all the world.[9]

But how conform this repose and spirit of permanency with the echoing tones of that never-ending, never-satisfied dominant chord? How reconcile the repose of those dropping billows with the tantalising unrest of that for ever incomplete, unfinished recessional that has been playing down this gorge since, perhaps, darkness brooded over the deep—that seems to await its fulfilment in the thunders of Sinai at that Last Day?

And what could be more human than this in any river—a seeming calm with over it all a never-ending cry of unrest, of wonder, of unsatisfied longing never to find repose until in that far resting-place of which Augustine thought when he wrote:
