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
