ONE:Telford succeeded to Brindley, with all his boldness and skill, and with much extended experience. He executed the Ellesmere canal, which occupied a length of upwards of a hundred miles, connecting the rivers Severn, Dee, and Mersey. In the construction of this canal Telford introduced a bold, but successful, novelty. In aqueducts, instead of puddling their bottoms with clay, which was not proof against the effects of frost, he cased them with iron, and adopted the same means when he had to pass through quicksands or mere bog. Some of Telford's aqueducts were stupendous works. The Chirk aqueduct passed, at seventy feet above the river, on ten arches of forty feet span, and cost twenty thousand eight hundred and ninety-eight pounds. The aqueduct over the Dee passed at a height of one hundred and twenty-one feet above low water, and consisted of a great trough of cast-iron plates, supported on eighteen piers, and having a towing-path of cast-iron, supported on cast-iron pillars. This aqueduct took ten years in building, and cost, with its embankments, forty-seven thousand pounds. Tunnels much larger than that at Harecastle Hill were executed. That at Sapperton, on the Thames and Severn canal, executed by Mr. Whitworth, was nearly two miles and a half long, ran two hundred and fifty feet below the summit of the hill, and was large enough for boats of seventy tons burden. This was completed in 1788. These daring enterprises led to the design of a tunnel under the Thames, from Gravesend to Tilbury; but this was abandoned for want of capital. In 1804 a like attempt was made at Rotherhithe, but stopped from the same cause, and was not completed till 1843 by Sir Mark Isambard Brunel. Between 1758 and 1801 no fewer than sixty-five Acts of Parliament were passed for making or extending canals. At the end of that period canals extended over upwards of three thousand miles, and had cost upwards of thirteen millions sterling. In fact, the bulk of canal work was done by this time, though not some few works of great importance. The Leeds and Liverpool canal, begun in 1770, but not completed till 1816, opened up connection with a vast manufacturing district; and the Rochdale, Huddersfield, and Hull canals gave access for the Baltic traffic into the heart of Lancashire. The Paddington and Regent's Canals wonderfully promoted the intercourse between the interior and the metropolis. In the Highlands, the Caledonian Canal, connecting the[192] string of lakes between Inverness and the Atlantic, gave passage to ships of large burden. At the end of this reign the aggregate length of canals in England and Wales was two thousand one hundred and sixty miles; in Scotland, two hundred and twelve; in Ireland, two hundred and fifty; total, two thousand six hundred and twenty-two miles. The attention paid to roads and canals necessitated the same to bridges; and during this reign many new structures of this kind were erected, and much improvement attained in their formation. In 1776 a totally new kind of bridge was commenced at Coalbrook Dale, and completed in 1779; this was of cast-iron, having a single arch of one hundred feet span, and containing three hundred and seventy-eight and a half tons of metal. Telford greatly improved on this idea, by erecting an iron bridge over the Severn, at Buildwas, in 1796, having an arch of one hundred and thirty feet span.At length it was announced that peace was signed with France at Utrecht, and it was laid before the Council (March 31, 1713). Bolingbroke had made another journey to the Continent to hasten the event, but it did not receive the adhesion of the Emperor at last. Holland, Prussia, Portugal, and Savoy had signed, but the Emperor, both as king of Austria and head of the Empire, stood out, and he was to be allowed till the 1st of June to accept or finally reject participation in it. This conclusion had not been come to except after two years' negotiation, and the most obstinate resistance on the part of all the others except England. Even in the English Cabinet it did not receive its ratification without some dissent. The Lord Cholmondeley refused to sign it, and was dismissed from his office of Treasurer of the Household. On the 9th of April the queen opened Parliament, though she was obliged to be carried thither and back in a chair in consequence of her corpulence and gout. She congratulated the country on this great treaty, declared her firm adherence to the Protestant succession, advised them to take measures to reduce the scandalous licentiousness of the Press, and to prevent duelling, in allusion to the tragic issue of that between Hamilton and Mohun. She finally exhorted them to cultivate peace amongst themselves, to endeavour to allay party rage; and as to what forces should be necessary by land and the sea, she added, "Make yourselves safe; I shall be satisfied. Next to the protection of Divine Providence, I depend on the loyalty and affection of my people; I want no other guarantee." On the 4th of May the proclamation of peace took place. It was exactly eleven years since the commencement of the war. The conditions finally arrived at were those that have been stated, except that it was concluded to confer Sicily on the Duke of Savoy for his services in the war; on the Elector of Bavaria, as some equivalent for the loss of Bavaria itself, Sardinia, with the title of king; and that, should Philip of Spain leave no issue, the Crown of Spain should also pass to him.
