Rising at the head of the outermost eastern gorge of the Black Mountains, the Monnow runs a course from its source to its mouth of unremitting loveliness. Met at the base of the mountains by the Honddu, coming fresh from the sacred pastures of mountain-girdled Llanthony, the united streams are still further reinforced at Pontrilas by the waters of the Golden Valley. Thence, running under the high-poised ruinous Castle of Grosmont, through the chase of Kentchurch Court, where another daughter of Glyndwr lived and her descendants live to-day, and onward yet down a deep, narrow vale overhung by hills over a thousand feet in height, washing the ivy-clad ruins of Skenfrith Castle, the beautiful stream slacks something for the last half-dozen miles of its pilgrimage to Monmouth. For the number and average weight of its fish the Monnow is perhaps the best trouting stream on the whole Welsh Borderland, which is saying a good deal, though the introduction of grayling has not been favourable to its maintaining its former high standard. It has given its name at any rate to a town, a county, and a king. A great king too was Harry of Monmouth, of whose birthplace, the Castle, there is not a great deal left, beyond the very perfect gateway on the Monnow Bridge. Regarding the county whose boundary against Herefordshire the Monnow forms for the greater part of its career, this was named, of course, from the town when Henry the Eighth created it out of many lordships. It would be ill forgetting, however, Geoffrey of Monmouth, whose "study," by a pious fiction, is pointed out to the stranger in a fragment still remaining of a twelfth-century Benedictine Priory. Whether Geoffrey as a historian was over-credulous or a bit of a wag does not matter. The later poets and their readers are much indebted to him for the Arthurian legend. If Arthur did not hold his Court at Monmouth, he held it at Caerleon, in the next valley, and the glorious Usk, child of the Black Mountains, and almost the Wye's equal in its upper reaches, is nowhere an English river--happily for our space. With the memory of many a ramble by the Teme and Lugg, the Monnow and the Honddu, it goes hard enough to pass them by, but the passing of the Usk in such light fashion would be harder still. As for Monmouth itself, there is nothing else remarkable about it, nor yet, fortunately, is there anything calculated to disturb the peaceful and romantic nature of its setting.
