With the reign of George III. commenced a series of improvements in the manufacture of iron, which have led not only to a tenfold production of that most useful of metals, but to changes in its quality which before were inconceivable. Towards the end of the reign of George II. the destruction of the forests in smelting iron-ore was so great as to threaten their extinction, and with it the manufacture of iron in Britain. Many manufacturers had already transferred their businesses to Russia, where wood was abundant and cheap. It was then found that coke made from coal was a tolerable substitute for charcoal, and, in 1760, the very first year of the reign of George III., the proprietors of the Carron Works in Scotland began the use of pit-coal. Through the scientific aid of Smeaton and Watt, they applied water-, and afterwards steam-power, to increase the blast of their furnaces to make it steady and continuous, instead of intermitting as from bellows; and they increased the height of their chimneys. By these means, Dr. John Roebuck, the founder of these works, became the first to produce pig iron by the use of coal. This gave great fame to the Carron Works, and they received large orders from Government for cannon and cannon-balls. It was some time, however, before enough iron could be produced to meet the increasing demand for railroads, iron bridges, etc.; and so late as 1781 fifty thousand tons were imported annually from Russia and Sweden.Whilst these events had been passing in Austria and Bavaria, the King of England had endeavoured to make a powerful diversion in the Netherlands. Under the plea of this movement sixteen thousand British troops were embarked in April for the Netherlands; but they were first employed to overawe Prussia, which was in contention with Hanover regarding the Duchy of Mecklenburg. There were other causes of dispute between Prussia and the Elector of Hanover. George having now this strong British force, besides sixteen thousand Hanoverian troops and six thousand auxiliary Hessians, Frederick thought proper to come to terms with him, and, in consequence of mutual arrangements, the Hanoverian troops quitted Mecklenburg, and George, feeling Hanover safe, marched this united force to the Netherlands to join the British ones. He expected the Dutch to co-operate with him and the Austrians, and strike a decided blow at France. But the Earl of Stair, who was to command these forces, and who was at the same time ambassador to the States, found it impossible to induce the Dutch to act. They had increased their forces both by sea and land, but they were afraid of the vicinity of the French, and were, with their usual jealousy, by no means pleased to see the English assuming power in the Netherlands. Therefore, after making a great demonstration of an attempt on the French frontier with the united army, the project was suddenly abandoned, and the troops retired into winter quarters. But little was accomplished during this year by the British fleet.WARREN HASTINGS.The two rival Ministers of England became every day more embittered against each other; and Bolingbroke grew more daring in his advances towards the Pretender, and towards measures only befitting a Stuart's reign. In order to please the High Church, whilst he was taking the surest measures to ruin it by introducing a popish prince, he consulted with Atterbury, and they agreed to bring in a Bill which should prevent Dissenters from educating their own children. This measure was sure to please the Hanoverian Tories, who were as averse from the Dissenters as the Whigs. Thus it would conciliate them and obtain their support at the[19] very moment that the chief authors of it were planning the ruin of their party. This Bill was called the Schism Bill, and enjoined that no person in Great Britain should keep any school, or act as tutor, who had not first subscribed the declaration to conform to the Church of England, and obtained a licence of the diocesan. Upon failure of so doing, the party might be committed to prison without bail; and no such licence was to be granted before the party produced a certificate of his having received the Sacrament according to the communion of the English Church within the last year, and of his having also subscribed the oaths of Allegiance and Supremacy.
