In 1786, when Telford was nearly thirty, a piece of unexpected good luck fell to his lot. And yet it was not so much good luck as due recognition of his sterling qualities by a wealthy and appreciative person. Long before, while he was still in Eskdale, one Mr. Pulteney, a man of social importance, who had a large house in the bleak northern valley, had asked his advice about the repairs of his own mansion. We may be sure that Telford did his work on that occasion carefully and well; for now, when Mr. Pulteney wished to restore the ruins of Shrewsbury Castle as a dwelling-house, he sought out the young mason who had attended to his Scotch property, and asked him to superintend the proposed alterations in his Shropshire castle. Nor was that all: by Mr. Pulteney's influence, Telford was shortly afterwards appointed to be county surveyor of public works, having under his care all the roads, bridges, gaols, and public buildings in the whole of Shropshire. Thus the Eskdale shepherd-boy rose at last from the rank of a working mason, and attained the well-earned dignity of an engineer and a professional man.

Telford had now a fair opportunity of showing the real stuff of which he was made. Those, of course, were the days when railroads had not yet been dreamt of; when even roads were few and bad; when communications generally were still in a very disorderly and unorganized condition. It is Telford's special glory that he reformed and altered this whole state of things; he reduced the roads of half Britain to system and order; he made the finest highways and bridges then ever constructed; and by his magnificent engineering works, especially his aqueducts, he paved the way unconsciously but surely for the future railways. If it had not been for such great undertakings as Telford's Holyhead Road, which familiarized men's minds with costly engineering operations, it is probable that projectors would long have stood aghast at the alarming expense of a nearly level iron road running through tall hills and over broad rivers the whole way from London to Manchester.

At first, Telford's work as county surveyor lay mostly in very small things indeed—mere repairs of sidepaths or bridges, which gave him little opportunity to develop his full talents as a born engineer. But in time, being found faithful in small things, his employers, the county magistrates, began to consult him more and more on matters of comparative importance. First, it was a bridge to be built across the Severn; then a church to be planned at Shrewsbury, and next, a second church in Coalbrookdale. If he was thus to be made suddenly into an architect, Telford thought, almost without being consulted in the matter, he must certainly set out to study architecture. So, with characteristic vigour, he went to work to visit London, Worcester, Gloucester, Bath, and Oxford, at each place taking care to learn whatever was to be learned in the practice of his new art. Fortunately, however, for Telford and for England, it was not architecture in the strict sense that he was finally to practise as a real profession. Another accident, as thoughtless people might call it, led him to adopt engineering in the end as the path in life he elected to follow. In 1793, he was appointed engineer to the projected Ellesmere Canal.

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!

While Telford was working busily upon his wonderful canal, he had many other schemes to carry out of hardly less importance, in connection with his appointment as county surveyor. His beautiful iron bridge across the Severn at Build was was another application of his favourite metal to the needs of the new world that was gradually growing up in industrial England; and so satisfied was he with the result of his experiment (for though not absolutely the first, it was one of the first iron bridges ever built) that he proposed another magnificent idea, which unfortunately was never carried into execution. Old London Bridge had begun to get a trifle shaky; and instead of rebuilding it, Telford wished to span the whole river by a single iron arch, whose splendid dimensions would have formed one of the most remarkable engineering triumphs ever invented. The scheme, for some good reason, doubtless, was not adopted; but it is impossible to look at Telford's grand drawing of the proposed bridge—a single bold arch, curving across the Thames from side to side, with the dome of St Paul's rising majestically above it—without a feeling of regret that such a noble piece of theoretical architecture was never realized in actual fact.

Telford had now come to be regarded as the great practical authority upon all that concerned roads or communications; and he was reaping the due money-reward of his diligence and skill. Every day he was called upon to design new bridges and other important structures in all parts of the kingdom, but more especially in Scotland and on the Welsh border. Many of the most picturesque bridges in Britain, which every tourist has admired, often without inquiring or thinking of the hand that planned them, were designed by his inventive brain. The exquisite stone arch which links the two banks of the lesser Scotch Dee in its gorge at Tongueland is one of the most picturesque; for Telford was a bit of an artist at heart, and, unlike too many modern railway constructors, he always endeavoured to make his bridges and aqueducts beautify rather than spoil the scenery in whose midst they stood. Especially was he called in to lay out the great system of roads by which the Scotch Highlands, then so lately reclaimed from a state of comparative barbarism, were laid open for the great development they have since undergone. In the earlier part of the century, it is true, a few central highways had been run through the very heart of that great solid block of mountains; but these were purely military roads, to enable the king's soldiers more easily to march against the revolted clans, and they had hardly more connection with the life of the country than the bare military posts, like Fort William and Fort Augustus, which guarded their ends, had to do with the ordinary life of a commercial town. Meanwhile, however, the Highlands had begun gradually to settle down; and Telford's roads were intended for the far higher and better purpose of opening out the interior of northern Scotland to the humanizing influences of trade and industry.

Fully to describe the great work which the mature engineer constructed in the Highland region, would take up more space than could be allotted to such a subject anywhere save in a complete industrial history of roads and travelling in modern Britain. It must suffice to say that when Telford took the matter in hand, the vast block of country north and west of the Great Glen of Caledonia (which divides the Highlands in two between Inverness and Ben Nevis)—a block comprising the counties of Caithness, Sutherland, Ross, Cromarty, and half Inverness—had literally nothing within it worthy of being called a road. Wheeled carts or carriages were almost unknown, and all burdens were conveyed on pack-horses, or, worse still, on the broad backs of Highland lassies. The people lived in small scattered villages, and communications from one to another were well-nigh impossible. Telford set to work to give the country, not a road or two, but a main system of roads. First, he bridged the broad river Tay at Dunkeld, so as to allow of a direct route straight into the very jaws of the Highlands. Then, he also bridged over the Beauly at Inverness, so as to connect the opposite sides of the Great Glen with one another. Next, he laid out a number of trunk lines, running through the country on both banks, to the very north of Caithness, and the very west of the Isle of Skye. Whoever to this day travels on the main thoroughfares in the greater Scottish Islands—in Arran, Islay, Jura, Mull; or in the wild peninsula of Morvern, and the Land of Lorne; or through the rugged regions of Inverness-shire and Ross-shire, where the railway has not yet penetrated,—travels throughout on Telford's roads. The number of large bridges and other great engineering masterpieces on this network of roads is enormous; among the most famous and the most beautiful, are the exquisite single arch which spans the Spey just beside the lofty rearing rocks of Craig Ellachie, and the bridge across the Dee, beneath the purple heather-clad braes of Ballater. Altogether, on Telford's Highland roads alone, there are no fewer than twelve hundred bridges.

Nor were these the only important labours by which Telford ministered to the comfort and well-being of his Scotch fellow-countrymen. Scotland's debt to the Eskdale stonemason is indeed deep and lasting. While on land, he improved her communications by his great lines of roads, which did on a smaller scale for the Highland valleys what railways have since done for the whole of the civilized world; he also laboured to improve her means of transit at sea by constructing a series of harbours along that bare and inhospitable eastern coast, once almost a desert, but now teeming with great towns and prosperous industries. It was Telford who formed the harbour of Wick, which has since grown from a miserable fishing village into a large town, the capital of the North Sea herring fisheries. It was he who enlarged the petty port of Peterhead into the chief station of the flourishing whaling trade. It was he who secured prosperity for Fraserburgh, and Banff, and many other less important centres; while even Dundee and Aberdeen, the chief commercial cities of the east coast, owe to him a large part of their present extraordinary wealth and industry. When one thinks how large a number of human beings have been benefited by Telford's Scotch harbour works alone, it is impossible not to envy a great engineer his almost unlimited power of permanent usefulness to unborn thousands of his fellow-creatures.

As a canal-maker, Telford was hardly less successful than as a constructor of roads and harbours. It is true, his greatest work in this direction was in one sense a failure. He was employed by Government for many years as the engineer of the Caledonian Canal, which runs up the Great Glen of Caledonia, connecting the line of lakes whose basins occupy that deep hollow in the Highland ranges, and so avoiding the difficult and dangerous sea voyage round the stormy northern capes of Caithness. Unfortunately, though the canal as an engineering work proved to be of the most successful character, it has never succeeded as a commercial undertaking. It was built just at the exact moment when steamboats were on the point of revolutionizing ocean traffic; and so, though in itself a magnificent and lordly undertaking, it failed to satisfy the sanguine hopes of its projectors. But though Telford felt most bitterly the unavoidable ill success of this great scheme, he might well have comforted himself by the good results of his canal-building elsewhere. He went to Sweden to lay out the Gotha Canal, which still forms the main high-road of commerce between Stockholm and the sea; while in England itself some of his works in this direction—such as the improvements on the Birmingham Canal, with its immense tunnel—may fairly be considered as the direct precursors of the great railway efforts of the succeeding generation.

The most remarkable of all Telford's designs, however, and the one which most immediately paved the way for the railway system, was his magnificent Holyhead Road. This wonderful highway he carried through the very midst of the Welsh mountains, at a comparatively level height for its whole distance, in order to form a main road from London to Ireland. On this road occurs Telford's masterpiece of engineering, the Menai suspension bridge, long regarded as one of the wonders of the world, and still one of the most beautiful suspension bridges in all Europe. Hardly less admirable, however, in its own way is the other suspension bridge which he erected at Conway, to carry his road across the mouth of the estuary, beside the grey old castle, with which its charming design harmonizes so well. Even now it is impossible to drive or walk along this famous and picturesque highway without being struck at every turn by the splendid engineering triumphs which it displays throughout its entire length. The contrast, indeed, between the noble grandeur of Telford's bridges, and the works on the neighbouring railways, is by no means flattering in every respect to our too exclusively practical modern civilization.

Telford was now growing an old man. The Menai bridge was begun in 1819 and finished in 1826, when he was sixty-eight years of age; and though he still continued to practise his profession, and to design many valuable bridges, drainage cuts, and other small jobs, that great undertaking was the last masterpiece of his long and useful life. His later days were passed in deserved honour and comparative opulence; for though never an avaricious man, and always anxious to rate his services at their lowest worth, he had gathered together a considerable fortune by the way, almost without seeking it. To the last, his happy cheerful disposition enabled him to go on labouring at the numerous schemes by which he hoped to benefit the world of workers; and so much cheerfulness was surely well earned by a man who could himself look back upon so good a record of work done for the welfare of humanity. At last, on the 2nd of September, 1834, his quiet and valuable life came gently to a close, in the seventy-eighth year of his age. He was buried in Westminster Abbey, and few of the men who sleep within that great national temple more richly deserve the honour than the Westerkirk shepherd-boy. For Thomas Telford's life was not merely one of worldly success; it was still more pre-eminently one of noble ends and public usefulness. Many working men have raised themselves by their own exertions to a position of wealth and dignity far surpassing his; few indeed have conferred so many benefits upon untold thousands of their fellow-men. It is impossible, even now, to travel in any part of England, Wales, or Scotland, without coming across innumerable memorials of Telford's great and useful life; impossible to read the full record of his labours without finding that numberless structures we have long admired for their beauty or utility, owe their origin to the honourable, upright, hardworking, thoroughgoing, journeyman mason of the quiet little Eskdale village. Whether we go into the drained fens of Lincolnshire, or traverse the broad roads of the rugged Snowdon region; whether we turn to St. Katharine's Docks in London, or to the wide quays of Dundee and those of Aberdeen; whether we sail beneath the Menai suspension bridge at Bangor, or drive over the lofty arches that rise sheer from the precipitous river gorge at Cartland, we meet everywhere the lasting traces of that inventive and ingenious brain. And yet, what lad could ever have started in the world under apparently more hopeless circumstances than widow Janet Telford's penniless orphan shepherd-boy Tam, in the bleakest and most remote of all the lonely border valleys of southern Scotland?
