THREE:The earliest idea of a steam-engine was that given by the Marquis of Worcester, in his "Century of Inventions," in 1663, which idea he obtained from De Caus, and reduced to action in London. The next step was to Papin's Digester, and then to Savery's so-called "Atmospheric Engine." This, improved by Newcomen in 1711,[195] was introduced to drain mines in all parts of the kingdom, but especially in the coal-mines of the north and midland counties, and the copper mines of Cornwall. By its means many mines long disused through the accumulation of water were drained and made workable, and others were sunk much deeper. Smeaton, in 1769, greatly improved this engine, which, from its rapid working of a horizontal beam, was called by the miners a "Whimsey," as having a whimsical look. Watt, then a student in the University of Glasgow, commenced a series of experiments upon it, which, between 1759 and 1782, raised the engine to a pitch of perfection which made it applicable not only to draining water out of mines, but, by the discovery of the rotatory motion, enabled it to propel any kind of machinery, spin cotton, grind in mills of all kinds, and propel ships and carriages. Watt was greatly aided in his efforts by Mr. Matthew Boulton, and their engines were manufactured at Soho Works, near Birmingham. They did not, however, enjoy the fruits of their patents for protecting their inventions without many most unprincipled attempts to invade their rights by masters of mines and others, by which they were involved in very harassing law-suits. The first application of the steam-engine to the machinery of a cotton-mill was at Papplewick, in Nottinghamshire, in 1785, and the first mill built for the employment of machinery driven by an engine was in Manchester, in 1789. The first application of the engine to propel a vessel was at Dalswinton, on the Clyde, in 1788, the boat being constructed by Patrick Miller, James Taylor, and William Symington. In the following year these inventors made a second experiment on the Forth and Clyde Canal at the Carron Works, with perfect success, the vessel going at the rate of nearly seven miles an hour. Symington was probably the real machinist in this firm, and in 1802 he made a tug-boat on the Forth and Clyde Canal, under the patronage of Lord Dundas, which was worked extremely well by its engine. In 1807 Fulton followed up these experiments by launching a steam-boat on the Hudson, in America, after having in vain solicited the patronage of the British and French Governments for his enterprise. The proposal of Fulton, submitted to the Academy of Paris, was received with a burst of laughter, and Napoleon abandoned the project in deep disgust at having been, as he supposed, made a dupe of by Fulton. We have pointed out on the preceding page the period of the first application of the steam-engine to railways.Whilst this progress in operatic and sacred music was being made, the Church Service had received some admirable additions. Jeremiah Clarke, the Rev. Henry Aldrich, D.D., dean of Christ Church, John Weldon, organist to Queen Anne, and Georges I. and II., and the Rev. Dr. Robert Creighton, canon of Salisbury, composed many admirable pieces. William Croft, Mus. Doc., is the author of thirty-one splendid anthems, and Maurice Greene, Mus. Doc., of forty, which are still heard with solemn delight in old choirs. William Boyce, Mus. Doc., organist to Georges II. and III., added to these numerous anthems and services the oratorio of "Solomon," and many other compositions of a superb characterone of them the grand anthem performed annually at the Feast of the Sons of the Clergy. Boyce also composed a variety of secular pieces of rare merit.
