CAST. Sir, is this fair? You have played the eaves-dropper. Why come you here?
EV. To counsel you to silence on these mysteries, sweetest Castaly: remember the fate of Master Kirke, of Aberfoyle, for his dabbling in elfin matters, which you may read in Sir Walter’s “Demonology.” Yet I will not flout all your fayrie legends; there may be _innocent_ illusions, that carry with them somewhat of morality and retribution,—seeing that there are good and bad spirits, which reward and punish mortality. But, in sooth, I never think of fairyland, without remembering that good Sir Walter, as sheriff of Selkirkshire, once took the deposition of a shepherd, who affirmed that he saw the good neighbours sitting under a hill-side: when, lo! it was proved that these were the _puppets of a showman_, stolen and left there by some Scotch mechanics. And, better still, the story of the Mermaid of Caithness, as related to Sir Humphrey Davy, and recorded in his “Salmonia;”—the mermaids, as I take it, being nearly allied to the _Nereid_, or Sea-fairy, and the reality of one about as true as that of the other.
Nature is wild and beautiful enough, without these false creations. Read her _truth_, fair lady, and leave the _fables_ to the fairies. There is not a ripple or a stone that is not replete with scientific interest, and yields not a study that both ennobles and delights the mind.
The doublings, or _horse-shoes_, of this Wye, or _Vaga_ as the Romans named it, within its circle of rocks, so exquisitely fringed with green and purple lichens (like the Danube, round the castle of Hayenbach in the gloomy gorge of Schlagen, or the Crook of Lune, in Westmoreland, and many others), illustrate at once the nature of the stratification on the earth’s surface; even the varied tints of these mountain streams may read the student a practic lesson in geology.
From the lime-rock springs the azure-blue, as the Glaslyn stream, at Beddgelert, the Rhone, and the Traun in Styria; from the chalk ripples the grey water of the Dee and the Arve; from the clay hills the stream comes down yellow, as “the Derwent’s amber wave;” and where the peat-mosses abound, especially in the autumnal flood, the stream is of a rich and dark sienna brown, as the Conway, and the Mawddach, in Merioneth; or even of transparent black, as the Elain, which flows down through the white schist rocks of Cardiganshire.
