But soon the trot declined once more into a walk, and a slow one too,for we entered a gloomy pass or gorge, whose rocky walls on either side effectually excluded what little light yet lingered in the sky. Cautiously picking our way, we slowly travelled on, until at length we became sensible of a faint red flush in the narrow strip of sky overhead. It seemed as though the sun had just wheeled back to give a forgotten message to some starry-night-watcher,or so my companion intimated. But, unfortunately for his theory, the dull red glare above us, which every moment deepened in intensity, was evidently the reflection of earthly, not heavenly fire. I had seen too many conflagrations to doubt that for an instant. Presently a dull, confused sound fell on our ears, and at a sudden turn round an angle of our mountain road we stood speechless as we gazed on a spectacle which Milton might have conceived and Martin painted.
"Far other light than that of day there shone
Upon the wanderers entering Padalon,"
murmured the artist, as he gazed on the strange scene. And strange indeed was it to our startled eyes. We stood on the end and summit of a mountain spur, some two thousand feet above the valley, or rather basin, below, from the centre of which burst forth a thousand fires, whose dull roardulled by distancewas like "the noise of the sea on an iron-bound shore." The extent of space covered by those strange, fierce fires must have amounted to many acres,in fact, did so, as we afterwards ascertained,and the effect produced by them may be partially imagined when it is remembered that these flames were of all hues, from rich ruby-red, to the pale lurid light of burning sulphur. Fancy all the gems of Aladdin's Palace or Sinbad's Valley in fierce flashing combustion, immensely magnified, and you may form some faint idea of the scene in that Welsh valley.
Stretching out, like spokes of a gigantic wheel, from their fiery centre, were huge embankments, like those of Titanic railways, whose summits and sides, especially towards their extremities, glowed in patches with all the hues of the rainbow. As I gazed wonderingly on one of these,a real mountain of light, far surpassing the Koh-i-Noor,I observed a dark figure gliding along its summit, pushing something before it, like a black imp conveying an unfortunate soul from one part of Tophet to another. At the extremity of the ridge the imp stopped, and suddenly there shot down the steep, not a tortured ghost, but a shower of radiant gems even more brilliant than those to which I have already referred.
