We now took a farewel view of the Mynach’s glen, and quitted its interesting scenery, with such sensations as one feels in losing a friend whose intercourse has afforded both pleasure and improvement. We then descended to the vale of Ystwith, but unenlivened by its scenery, for a morning mist floated through the valley and spread a veil over its charms. A handsome park gate announced the entrance of HAFOD, and the thundering of an unseen waterfall formed a grand symphony to the spectacle that we were soon to witness.—Almost immediately the cloud of mist disappeared, rising like a huge curtain before us, and discovered such an assemblage of beauties, of cheerful walks and silent glens, of woody precipices, shadowy glades, garden thickets and waterfalls, that, considered with the barren wilds of the surrounding country, it secured a second Paradise rising from a newly-subsided chaos. This charming place, occupying a deep narrow valley, watered by the Ystwith, is the creation of Col. Johnes, whose persevering genius has forced a mantle of wood upon rocky precipices where nature seemed to deny the access of verdure, and who in his elegant and useful projects of farther improvement gives employment to the country around. Upon a spot judiciously chosen, where the banks of the valley gently incline, and the coverture of lofty woods afford a shelter from the north-eastern winds, stands the mansion, with a sloping lawn in front, commanding a comprehensive view of the enchanting valley; which if Dryden could but see, he would wish to recall the line, “God never made his works for man to mend.” On putting ourselves under the direction of the gardener, we were first led to the kitchen-garden, furnished with extensive forcing-houses, and replete with every necessary appendage. The flower-garden also displayed its appropriate charms; but from these atchievements of art we turned, without regret, to where the bold hand of nature reared the scene in stupendous majesty; “There along the dale, With woods o’erhung, and shagg’d with mossy rocks, Where on each hand the gushing waters play, And down the rough cascade white dashing fall,” we passed, enamoured with the incessant though congenial variety of our subject. After visiting the cold bath, a small sequestered building, a mazy walk romantically traced by the side of a brawling torrent, and amidst tangled shrubberies, led to a small cascade; and soon after a superior waterfall engaged our attention, where the whole volume of the Ystwith burst over a ledge of rocks in a composition truly grand and picturesque. But a scene of awful sublimity disclosed itself on exploring a dark cavernous passage in a rock and reaching its extremity, where a lofty cascade of transcendent beauty, throwing itself over a strata of black rocks, bounded close to the opening of the cave, and shrouded the aperture with its spray, as it became engulphed in a dark chasm beneath.
