Among the mountains of Wales it was my fortune to light on many a wild spot, where the poetry of nature fell like the sun-light on the heart of the peasant. In the beautiful vale of Neath there is the tiny hamlet of Pont-Neath-Vechan. I shall ever remember how fair and beautiful it seemed as I descended from the mountain rocks of Pen y Craig, the loftiest of the Alps of Glamorgan, which inclose Ystrad-Vodwg, the “village of the green valley.” Around its humble cottages is spread the most romantic scenery of Brecknockshire. The tributaries of its rolling river there blend their waters—those torrent streams which Drayton has impersonated in the Polyolbion, as “Her handmaids Meltè sweet, clear Hepstè, and Tragath.” On the Meltè is the wondrous cavern of Porth-Mawr, through which, in Stygian darkness, flows this Acherontic river. And on the clear Hepstè is that glittering waterfall which in the midst of leafy woods and bosky glens, throws itself, like a miniature Niagara, from the rock, forming an arch of crystal, beneath which the traveller and the peasant cross the river’s bed on the moss-green and slippery limestone. Oh! for the pencil of a Salvator, the pen of Torquato, to picture the wild vision which was before my eyes when I sought shelter beneath this crystal canopy from the deluge of a thunder-cloud. The lightning flash gleamed through the waterfall, forming a prismatic rainbow of transcendent beauty, while the deep peal swept through the echoing dingles, and the crimson-spotted trout leaped in sportive summersaults over the water-ousel that was walking quietly on the gravel, deep in the water.
