James Bradley (b. 1692), who succeeded Halley as the third Astronomer Royal, held that post till 1762, when he died. He had in 1728 distinguished himself by his discovery of an unanswerable proof of the motion of the earth by his observations on the apparent alteration in the place of a fixed star. His second great discovery was that of the mutation of the earth's axis, showing that the pole of the equator moves round the pole of the elliptic, not in a straight but in a waving line. Bradley gave important assistance to the Ministry in their alteration of the calendar in 1751, and the vast mass of his observations was published after his death, by the University of Oxford, in two volumes, in 1798.
George had, if anything, a narrower intellect than his father, but spoke English fluently, though with a foreign accenta great advantage over his predecessor. He was small of stature, and subject to fits of violent passion, neither of which qualities was conducive to royal dignity. Nor did the attributes of his mind supply any gain calculated to remedy these defects. He was possessed of courage, which he had proved at the battle of Oudenarde, and displayed again at Dettingen, and he was praised for justice. Perhaps it was a love of order and etiquette rather than justice which distinguished him. For his sort of military precision and love of soldiers he was nicknamed the "Little Captain" by the Jacobites. But the worst trait of his disposition was his avarice. He admitted, says Lord Chesterfield, that he was much more affected by little things than great onesthe certain mark of a little mind; he therefore troubled himself very little about religion, but took it as he found it, without doubt, objection, or inquiry. He hated and despised all literature and intellectual pursuit, arts and sciences, and the professors of them.
"They have expressed the desire that I should convey to you, Colonel"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.
