This profound valley, or rather, meeting-place of valleys, is a kind of rendezvous of many waters—the Machno, the Llugwy, the Lledr—pouring into the Conway. Fairy glens and waterfalls abound down below in those dense woods, and on still summer days, when the winds are hushed, one may hear the voices of those confluent streams and falls, mingled in a hoarse whisper. The pilgrim, strange to this road, adventuring afoot or awheel from these commanding heights onward and downwards to Bettws, is presently possessed with a curiosity to know how much further the descent goes. Downward and still down, meeting cyclists, carriages, and waggonettes crawling up, he goes and, passing another toll-house, comes at last to the valley, beside the Conway again. Here, where the road turns with a singular abruptness to the left, Telford has spanned that stream with the Waterloo Bridge, a single cast-iron arch, beautiful in itself, and, decorated with emblematic and symbolic representations of the Rose, Thistle, Shamrock, and Leek—the floral and vegetable badges of our composite kingdoms and principalities—proving that Telford had something of the artistic sense, as well as engineering genius. Cast-iron lettering, pierced and easily to be read, follows the course of the arch and explains why “Waterloo” Bridge was so named. “This arch,” it says, “was constructed in the same year the battle of Waterloo was fought.” The names of Telford, of the iron-founder, and of the foreman of works, are all recorded in cast iron.
