By this time the descent on the grass was getting too steep and slippery to admit of our continuing to advance in that direction. We turned, therefore, down the valley in the direction of the sea. It was but a narrow cleft, and narrowed much towards a deeper cleft, in which we now saw the tops of trees, and from which we heard the rush of water. Nor had we gone far in this direction before we came upon a gate in a stone wall, which led into what seemed a neglected garden. We entered, and found a path turning and winding, among small trees, and luxuriant ferns, and great stones, and fragments of ruins down towards the bottom of the chasm. The noise of falling water increased as we went on, and at length, after some scrambling and several sharp turns, we found ourselves with a nearly precipitous wall on each side, clothed with shrubs and ivy, and creeping things of the vegetable world. Up this cleft there was no advance. The head of it was a precipice down which shot the stream from the vale above, pouring out of a deep slit it had itself cut in the rock as with a knife. Halfway down, it tumbled into a great basin of hollowed stone, and flowing from a chasm in its side, which left part of the lip of the basin standing like the arch of a vanished bridge, it fell into a black pool below, whence it crept as if half-stunned or weary down the gentle decline of the ravine. It was a perfect little picture. I, for my part, had never seen such a picturesque fall. It was a little gem of nature, complete in effect. The ladies were full of pleasure. Wynnie, forgetting her usual reserve, broke out in frantic exclamations of delight. We stood for a while regarding the ceaseless pour of the water down the precipice, here shot slanting in a little trough of the rock, full of force and purpose, here falling in great curls of green and gray, with an expression of absolute helplessness and conscious perdition, as if sheer to the centre, but rejoicing the next moment to find itself brought up boiling and bubbling in the basin, to issue in the gathered hope of experience. Then we turned down the stream a little way, crossed it by a plank, and stood again to regard it from the opposite side. Small as the whole affair was--not more than about a hundred and fifty feet in height--it was so full of variety that I saw it was all my memory could do, if it carried away anything like a correct picture of its aspect. I was contemplating it fixedly, when a little stifled cry from Wynnie made me start and look round. Her face was flushed, yet she was trying to look unconcerned. "I thought we were quite alone, papa," she said; "but I see a gentleman sketching."
