TWO:Iron suspension bridges were also introduced towards the end of this reign. Chain bridges had been erected in China for nearly two thousand years, and rope bridges in India and South America still earlier. In England a foot-bridge of iron chains was erected at Middleton, over the Tees, in the middle of the eighteenth century. In 1816 a bridge of iron wire was thrown across the Gala Water; and another, on a different principle, the following year, was erected over the Tweed, at[193] King's Meadows. But now much greater and more complete works of the kind were to be executed. Captain (afterwards Sir Samuel) Brown introduced many improvements into these structures. He substituted iron ropes for hempen ones, thereby forming cable-chains, like those used in Wales on quarry tram-roads, and these he applied to suspension bridges. In 1819 he was commissioned to construct an iron suspension bridge over the Tweed, near Kelso, called the union Bridge, which he completed in 1820, at a cost of five thousand pounds. In 1827 the first suspension bridge was thrown over the Thames by Mr. William Tierney Clarke; and in 1818 Telford commenced his great work of throwing a suspension bridge over the Menai Strait, near Bangor, which he completed in 1825. The main opening of this stupendous work is five hundred and sixty feet wide, and one hundred feet above high-water mark. The length of the roadway of the bridge is one thousand feet. The cost was one hundred and twenty thousand pounds. This was Telford's chef-d'?uvre. But the same neighbourhood was destined to see a more stupendous structure span the Strait from the Welsh shore to Anglesey. This was the tubular railway bridge, connecting the London and Holyhead line, within view of Telford's elegant suspension bridge. This was erected by Robert Stephenson, from his own design, greatly improved by suggestions from William Fairbairn of Manchester. It was completed in October, 1850, at a cost of six hundred and twenty-five thousand eight hundred and sixty-five pounds. Further description of this great work is not proper here, as it belongs to a later date, but it seemed fit to mention it in passing, as an evidence of the progress of the engineering science in the reign of Victoria.During this momentous struggle, Russia was munificently supported by Great Britain. The peace which Mr. Canning, afterwards Lord Stratford de Redcliffe, our ambassador at Constantinople, had been the means of effecting between Turkey and Russia, released Admiral Tchitchagoff and his army of thirty thousand men to march against Buonaparte; and had not that stupid personage suffered himself to be so grossly deceived by the French Emperor at the Beresina, neither Buonaparte nor a man of his army had ever got across that river. At the same time peace was made with Russia by Great Britain, and Russia sent her fleet, for security, to an English port during the invasion. Peace also was ratified between Great Britain and Sweden; and Bernadotte was at liberty to pursue his plans for aiding in the general movement of the North for the final extinction of the Buonaparte rule. Great Britain also bountifully supplied the Russians with money and arms, and other necessaries, so that a French officer who accompanied General Lauriston to the headquarters of the Russian army was astonished to find abundance of British money circulating and in the highest esteem, though Buonaparte had represented Great Britain as on the verge of bankruptcy. "When I saw British bank-notes passing," he said, "as if they were gold, I trembled for our daring enterprise."
