The progress of our manufactures was equally satisfactory. At the commencement of this period that great innovator and benefactor, the steam-engine, was produced. The idea thrown out by the Marquis of Worcester, in his "Century of Inventions," in 1663, had been neglected as mere wild theory till Savery, in 1698, constructed a steam-engine for draining mines. This received successive improvements from Newcomen and Crawley, and further ones from Brindley in 1756, and Watt extended these at the end of this period, though this mighty agent has received many improvements since. Navigable canals, also, date their introduction by the Duke of Bridgewater, under the management of Brindley, from the latter end of this period, 1758. Other great men, Arkwright, Compton, Hargreaves, etc., were now busily at work in developing machinery, and applying steam to it, which has revolutionised the system of manufacture throughout the world. In 1754 the Society of Arts and Manufactures was established.
One great article of manufacture and export, however, down to this period, continued to be that of our woollens. To guard this manufacture many Acts had been passed at different times, prohibiting the exportation of the raw material. Immediately after the Revolution a fresh Act of this kind was passed, and such was the jealousy even of the Irish and of our American colonies weaving woollen cloths, that, in 1689, an Act was passed prohibiting the exportation of wool or woollen goods from Ireland or our plantations to any country except England. Having taken measures thus to confine as much as possible the profit of the woollen manufacture to England, the next year, which saw all protecting duties taken off corn, saw also leave given for the exportation of woollen cloths duty-free from England to any part of the world. Sir William Davenant estimates the value of the yearly growth of wool in England at this time at about £2,000,000, and the value of its woollen manufactures at £8,000,000. He calculates that one-fourth of this amount was exported. In 1738 Mr. John Kay invented the mode of casting the shuttle by what is called a "picking-peg," by which means the weaver was enabled to weave cloths of any width, and throw off twice the quantity in the same time. In 1758 the Leeds Cloth Hall was erected, and, about twenty years afterwards, a hall for white cloths.
The silk trade received a great impulse by the erection of a silk-mill at Derby, in 1719, by John Lombe and his brothers. Lombe had smuggled himself into a silk-mill in Italy, as a destitute workman, and had then copied all the machinery. To prevent the operation of this new silk factory in England—which was worked by a water-wheel on the river Derwent, had 97,746 wheels, movements, and individual parts, and employed three hundred persons—the King of Sardinia prohibited the exportation of the raw material, and thus, for a time, checked the progress of the manufacture. Parliament voted Sir Thomas Lombe £14,000 as a compensation for loss of profits thus occasioned, on condition that the patent, which he had obtained for fourteen years, should expire, and the right to use the machinery should be thrown open to the public. By the middle of this period our silk manufactures were declared superior to those of Italy, and the tradesmen of Naples recommended their silk stockings as English ones. In 1755 great improvements were introduced by Mr. Jedediah Strutt in the stocking-loom of Lee.
As the woollen manufactures of Ireland had received a check from the selfishness of the English manufacturers, it was sought to compensate the Protestants of Ulster by encouraging the linen manufacture there, which the English did not value so much as their woollen. A Board was established in Dublin in 1711, and one also in Scotland in 1727, for the purpose of superintending the trade, and bounties and premiums on exportation were offered. In these favourable circumstances the trade rapidly grew, both in Ireland and Scotland. In 1750 seven and a half million yards of linen were annually woven in Scotland alone.
The lace manufacture was still prosecuted merely by hand, and chiefly in Buckinghamshire, Bedfordshire, and in the West of England. No lace was produced from machinery before 1768.
In the manufacture of iron a most material discovery of smelting the ore by the use of pit-coal was made. The forests of England were so much reduced by the consumption of wood in the iron furnaces, that it was contemplated removing the business to our American colonies. This necessity was obviated by the discovery by Dud Dudley of a mode of manufacturing bar-iron with coal instead of wood. This discovery had been patented in 1619, yet, singularly, had been neglected; but in 1740 the principle was applied at Coalbrookdale, and iron thus made tough or brittle, as was wished. Iron works, now not confined to one spot by the necessity of wood, sprang up at various places in England and Wales, and the great works at Rotherham were established in 1750, and the famous Carron works in Scotland in 1760. The quantity of pig-iron made in 1740 was calculated at 17,000 tons, and the number of people employed in the iron trade at the end of this period is supposed to be little short of 300,000.
The production of copper during this period was so plentiful, that, though the great mines in Anglesea were not yet discovered, full liberty was given to export it, except to France. From 1736 to 1745 the mines of Cornwall alone produced about 700 tons annually, and the yearly amount was constantly increasing. A manufactory of brass—the secret of which mixture was introduced from Germany, in 1649—was established in Birmingham, in 1748; and, at the end of this period, the number of persons employed in making articles of copper and brass was, probably, not less than 50,000. The manufacture of tinned iron commenced in Wales about 1730, and in 1740 further improvements were made in this process. Similar improvements were making in the refinement of metals, and in the manufacture of silver plate, called Sheffield plate. English watches acquired great reputation, but afterwards fell into considerable disrepute from the employment of inferior foreign works. Printing types, which we had before imported from Holland, were first made in England in the reign of Queen Anne, by Caslon, an engraver of gun-locks and barrels. In 1725 William Ged, a Scotsman, discovered the art of stereotyping, but did not introduce it without strong opposition from the working printers. Great strides were made in the paper manufacture. In 1690 we first made white paper, and in 1713 it is calculated that 300,000 reams of all kinds of paper were made in England. An excise duty was first laid on paper in 1711. Our best china and earthenware were still imported, and, both in style and quality, our own pottery was very inferior, for Wedgwood had not yet introduced his wonderful improvements. Defoe introduced pantiles at his manufactory at Tilbury, before which time we imported them from Holland. The war with France compelled us to encourage the manufacture of glass; in 1697 the excise duty, imposed three years before, was repealed, but in 1746 duties were imposed on the articles used in its manufacture, and additional duties on its exportation. The manufacture of crown glass was not introduced till after this period.
The effects of the growth in our commerce and manufactures, and the consequent increase of the national wealth, were seen in the extension of London and other of our large towns. Eight new parishes were added to the metropolis during this period; the Chelsea Waterworks were established in 1721; and Westminster Bridge was completed in 1750. Bristol, Hull, Liverpool, Manchester, Birmingham, Sheffield, Leeds, Edinburgh, Glasgow, Frome, Dublin, and several other towns, grew amazingly.
