If the Severn under its infant name of Hafren leaps towards such modified civilization as Llanidloes and the lonely trail of the Cambrian railway implies, amid solitudes profound, the Wye, though running even longer in the wild, has the company almost from its source of that ancient coach-road that in the good old stay-at-home days took even persons of condition on their wedding tours to Aberystwith. It was a wild and long way though, and its solitudes must have struck something like terror into the hearts of a Midland or East Anglian squire of the Regency period, getting outside the hedges as it were for the first time in his life, and looking possibly for the only one, upon actual mountains and tumbling streams. The Severn running north-east, and drawing mainly on the fountains of North Wales in its way to Welshpool and Shrewsbury, taps another country from the Wye. The latter is soon swollen into quite a large river by many lusty affluents from one of the wildest and most prolific watersheds in England or Wales. Birmingham, some of us may regret, has already discovered and laid this last under tribute. London engineers have had it all surveyed this ten years, and some day it is to be feared London will make it a burning question. The ordinary Londoner of intelligence, however, knows nothing about it outside possibly the path from Aberystwith to the top of Plinlimmon and back. Of its great lonely heart, tuneful only with the noise of waters, the bleat of sheep, and the plovers' cry, of its romantic girdle of crag and wood, of little white-washed sycamore shaded homesteads and rude hoary shrines of British saints through which these bog-fed torrents break, the outer world knows absolutely nothing at all. Here, however, are about 600 to 800 square miles of more continuously wild upland than anything even in North Wales, all lying in a block, to which the counties of Montgomery, Radnor, Brecon, Cardigan, and Caermarthen each contribute a slice. A land penetrated by no roads south of the Upper Wye, though pricked around its edges by rough and short-lived arteries [Illustration: THE WYE, HAY, BRECONSHIRE] [Illustration] for local use. A region whose hidden charms are for the stout pedestrian alone, but have remained so far undiscovered even by him, for practically no human form but the Welsh-speaking sheep farmer on his pony or some more than commonly adventurous angler or occasional grouse shooter ever breaks upon the solitude of this far-reaching mountain waste even in mid-August. This barrier, so broad, so lofty, and so long, which counted for so much in Welsh history, was known by the men of old as "the mountains of Ellineth." They have now no composite name, and there is not a range in Britain needs one more. It is as if Dartmoor and Exmoor, which could be together dropped into this other one, each lacked a concrete designation.
