Time was to show how wide were the issues to which this religious developement and the sentiment of humanity which it generated were to tend. But at the moment they told less directly and immediately on the political and social life of England than an industrial revolution which accompanied them. Though England already stood in the first rank of commercial states at the accession of George the Third, her industrial life at home was mainly agricultural. The growth of her manufactures was steady, but it continued to be slow; they gave employment as yet to but a small part of the population, and added in no great degree to the national wealth. The wool-trade remained the largest, as it was the oldest of them; it had gradually established itself in Norfolk, the West Riding of Yorkshire, and the counties of the south-west; while the manufacture of cotton was still almost limited to Manchester and Bolton, and though winning on its rival remained so unimportant that in the middle of the eighteenth century the export of cotton goods hardly reached the value of fifty thousand a year. There was the same slow and steady progress in the linen trade of Belfast and Dundee, and the silks of Spitalfields. But as yet textile manufactures contributed little to the national resources; nor did these resources owe much to the working of our minerals. The coal trade was small, and limited by the cost of carriage as well as by ignorance of any mode of employing coal in iron-smelting. On the other hand the scarcity of wood, which was used for that purpose, limited the production of iron. In 1750 only eighteen thousand tons were produced in England; and four-fifths of its iron goods were imported from Sweden. Nor did there seem any likelihood of a rapid change. Skilled labour was scarce; and the processes of manufacture were too rude to allow any large increase of production. It was only where a stream gave force to turn a mill-wheel that the wool-worker could establish his factory; and cotton was as yet spun by hand in the cottages, the "spinsters" of the family sitting with their distaffs round the weaver's hand-loom.
