The peculiarity in the manufacture of silk-twist, or thread, as distinguished from that of cotton, or flax, or wool, is that it is produced naturally in one uninterrupted length. The object of the machinery of a silk-mill is, not to combine short fibres in a continuous thread by spinning, but to wind and twist, so as to unite many slight threads already formed into one thread of sufficient strength for the purpose of weaving, or of sewing. The subsequent processes are the same as with the fibrous substances. The machinery by which these processes are carried on has been improved, by successive degrees, since Thomas Lombe erected the first silk-mill at Derby, in the beginning of the 18th century. He obtained a patent which expired in 1732; and parliament, refusing to renew his patent, granted him a compensation, upon the condition that he should deposit an exact model of his machinery in the Tower of London. That model was shown to the visitors of the Tower in the present century; and, by comparison with the vast array of spindles in a modern silk-mill, would seem as inefficient as the flail compared with the thrashing-machine. Ribbon-weaving is a branch of the silk manufacture, in which our country is rapidly attaining an excellence as regards beauty of design, which may fairly compete with the best productions of the French looms. * * * * * Thomas Firmin, a philanthropic writer, who published 'Proposals for the Employment of the Poor,' in 1681, says, "It is a thing greatly to be wished that we could make linen cloth here as cheap as they send it us from abroad." He thought the poor might then be employed; but he despairingly adds, "if that cannot be done, nor any other way found out to employ our poor people, we had much better lose something by the labour of our poor, than lose all their labour;" and so he proposes to give those who were idle flax and hemp to spin in spacious workhouses. The notion was a benevolent one; and it was the favourite scheme, for half a century, to destroy idleness and beggary in England, by setting up manufactories at the public cost. Defoe saw the fallacy of the principle, and resisted it with his strong common sense: "Suppose now a workhouse for the employment of poor children sets them to spinning of worsted. For every skein of worsted these poor children spin, there must be a skein the less spun by some poor person or family that spun it before." Defoe saw that there could be no profitable increase of labour without increase of consumption; and he argues that if the Czar of Muscovy would order his people to wear stockings, and we could supply them, the poor might then be set to work. The increase of consumption, all over the world, is produced by the inventions which diminish the cost of production. We now make linen cloth here cheaper than it is sent to us from abroad; and the result is that in 1853 we exported our linen
