As the "Druidical" origin has been popular, and lest there may still be a lingering doubt with some as to the natural origin of the "Pots and Pans," it may be added that upon the high grounds within a few miles of Todmorden there have been reckoned up nearly eight hundred similar cavities, the diameter varying from a few inches to four or five feet. They may be observed indeed in every stage of formation, thus altogether neutralizing the idea of their having been produced by artificial means. They occur, moreover, only in this particular series of the millstone-grit, other descriptions of grit in the neighbourhood--those not so amenable to the action of the weather--being entirely without. Very often, too, the basins are in positions such as neither Druids or any one else would ever select for ritual or ceremonials. The number of basins is itself an argument against the Druidical origin, since so many would never possibly be required, to say nothing of the fairly determined fact that the Druidical altar was usually a _cromlech_, formed by placing a great slab of stone horizontally upon the edges of two other slabs fixed in the ground vertically. But we are bound for Seal Bark. To get hither, the road must be quitted near the "Moorcock," and a way found through the fir-wood to the bottom of the valley, then re-ascending by the borders of the stream. A water so wild and beautiful it would be difficult to find nearer than Scotland or Carnarvonshire. Sliding, gliding, tumbling, in every conceivable mode, now it hurries along a smooth and limpid current; now it plays with the boulders, and changes to little cascades; now it fills little bays and recesses with reposing foam as white as snow, or that are alive with circular processions of untiring bubbles that swim awhile delicately, round and round, then, like the dancers in Sir Roger de Coverley, when they bend beneath the arch of lifted arms, rejoin their first partners and away down the middle, away and away, as swift as thought. Great defiles open on the right and left, Rimmon Clough and Birchen Clough, at the foot of which stands the one solitary tree of this grand wilderness--a mountain-ash, the tree of all others accustomed to loneliness. Above, at a vast height, is Ravenstone Brow, so named from the number of birds that once nested thereabouts, and where cuckoos still come. When at length we arrive at Seal Bark, who shall mistake it? All the waste and broken rock of a kingdom seems to have been pitched over the brow, and let fall and roll or stop just where it liked. The probability is that at some remote period the torrent undermined one side of the gorge, the ruins toppling over much in the same way as those of the ancient Clevedon shore, where it is plain that the fragments owe their present position to the remorseless beating of the sea.
