In the days before railways, such a canal as this was an engineering work of the very first importance.  It was to connect the Mersey, the Dee, and the Severn, and it passed over ground which rendered necessary some immense aqueducts on a scale never before attempted by British engineers.  Even in our own time, every traveller by the Great Western line between Chester and Shrewsbury must have observed on his right two magnificent ranges as high arches, which are as noticeable now as ever for their boldness, their magnitude, and their exquisite construction.  The first of these mighty archways is the Pont Cysylltau aqueduct which carries the Ellesmere Canal across the wide valley of the Dee, known as the Vale of Llangollen; the second is the Chirk aqueduct, which takes it over the lesser glen of a minor tributary, the Ceriog.  Both these beautiful works were designed and carried out entirely by Telford.  They differ from many other great modern engineering achievements in the fact that, instead of spoiling the lovely mountain scenery into whose midst they have been thrown, they actually harmonize with it and heighten its natural beauty.  Both works, however, are splendid feats, regarded merely as efforts of practical skill; and the larger one is particularly memorable for the peculiarity that the trough for the water and the elegant parapet at the side are both entirely composed of iron.  Nowadays, of course, there would be nothing remarkable in the use of such a material for such a purpose; but Telford was the first engineer to see the value of iron in this respect, and the Pont Cysylltau aqueduct was one of the earliest works in which he applied the new material to these unwonted uses.  Such a step is all the more remarkable, because Telford’s own education had lain entirely in what may fairly be called the “stone age” of English engineering; while his natural predilections as a stonemason might certainly have made him rather overlook the value of the novel material.  But Telford was a man who could rise superior to such little accidents of habit or training; and as a matter of fact there is no other engineer to whom the rise of the present “iron age” in engineering work is more directly and immediately to be attributed than to himself.

Meanwhile, the Eskdale pioneer did not forget his mother.  For years he had constantly written to her, in print hand, so that the letters might be more easily read by her aged eyes; he had sent her money in full proportion to his means; and he had taken every possible care to let her declining years be as comfortable as his altered circumstances could readily make them.  And now, in the midst of this great and responsible work, he found time to “run down” to Eskdale (very different “running down” from that which we ourselves can do by the London and North Western Railway), to see his aged mother once more before she died.  What a meeting that must have been, between the poor old widow of the Eskdale shepherd, and her successful son, the county surveyor of Shropshire, and engineer of the great and important Ellesmere Canal!
