Our travelling continued in rocky tracks, at the rate of a mile an hour, until we recovered the Llandilo road; from which we soon turned off, on the right, to visit Glenheir waterfall, in the grounds of Mr. Dubaison, about five miles south of Llandilo. At this place the Loughor river pursues its course between steep banks clothed with various trees and shrubs. On one of the descents a walk is traced, with some ingenuity, in front of a small picturesque cascade formed by a tributary stream to the Loughor. This might be mistaken for the object sought; but, crossing a rustic bridge, the eye on a sudden encounters the whole river rushing beneath a portal of trees, and throwing itself over a ledge of black rock in a single fall of eighteen feet. The effect of the whole, seen through the gloom of pendent trees, is undoubtedly striking; though, it must be confessed, the sheet of water presenting the formality of an unbroken square is somewhat unpicturesque. The person who attended us pointed out the effects of the torrent at fifteen feet above its surface, to which height it was swelled in the morning by the late storm; a greater rise than was ever known before: the cataract then exhibited a scene more tremendously grand than imagination can picture, or words describe; yet some idea may be formed in conceiving so vast a bulk of water, bursting over the precipice, stunning with its roar, and filling the atmosphere with its spray; while up-rooted trees, the shattered fragments of buildings, and other ruins, swept headlong on by the irresistible torrent, would illustrate its terrors, and complete a spectacle great indeed! Yet, alas, at how high a purchase, appeared from the lamentations of the neighbourhood! Nor were we without a share in the general calamity; for, crossing the Loughor at a ford about two miles further, my poney on a sudden slipped out of his depth, and we had separately to swim for our lives to the opposite bank. This disagreeable business was much aggravated; for my books, papers, and some other articles which I carried in a leather-case behind the saddle, were completely soaked, and several drawings utterly spoiled. My companion, having a taller horse, escaped, with only his boots full of water. Here it may not be amiss to apprize the traveller through Wales, that these fords (frequently occurring) are not unattended with danger after great falls of rain: at such times, a careful enquiry should be made of the people near them: a precaution that would have saved us our ducking; for it afterwards appeared, that no other travellers had crossed the ford during the day, but avoided it by taking a circuitous route.
