§ 10. The new industrial forces first applied to the cotton spinning of South Lancashire, and rapidly forcing their way into other branches of the textile manufactures, then more gradually transforming the industrial methods of the machinery, hardware, and other staple English manufactures, passed into the Western Continent of Europe and America, destroying the old domestic industry and establishing in every civilised country the reign of steam-driven machinery. The factors determining the order and pace of the new movement in the several countries are numerous and complex. In considering the order of machine-development, it must be remembered that the different nations did not start from an equal footing at the opening of the age of great inventions. By the beginning of the eighteenth century England had established a certain supremacy in commerce. The growth of her colonial possessions since the Revolution and the drastic and successful character of her maritime policy had enabled her to outstrip Holland. In 1729 by far the greater part of the Swedish iron exported from Gothenburg went to England for shipbuilding purposes.[83] At the close of the seventeenth century Gregory King placed England, Holland, and France at the head of the industrial nations with regard to the productivity of their labour.[84] Italy and Germany were little behind in the exercise of manufacturing arts, though the naval superiority and foreign possessions of the above-named nations gave them the commercial superiority. By 1760 England had strengthened her position as regards foreign commerce, and her woollen industry was the largest and most highly-developed industry in the world. But so far as the arts of manufacture themselves were concerned there was no such superiority in England as to justify the expectation of the position she held at the opening of the nineteenth century. In many branches of the textile arts, especially in silk spinning and in dyeing, in pottery, printing, and other manufactures, more inventive genius and more skill were shown on the Continent, and there seemed _à priori_ no reason why England should outstrip so signally her competitors. The chief factors in determining the order of the development of modern industrial methods in the several countries may be classified as natural, political, economic.
