The day was to come, however, when it would be a question, not of the additions made to inland navigation justifying the expense incurred, but of the inherent defects of the said "mighty works," the increasing manufactures, and the introduction of still better methods of transport and communication giving to canals a set-back akin to that which they themselves had already given to navigable rivers.
Contemporaneously with the canal period in England came an industrial revolution which was to place this country--hitherto distinctly backward in the development of its industries--at the head of manufacturing nations, but was, also, to show that, however great the advantages conferred by canals, as compared both with rivers and with roads, even canals were inadequate to meet the full and ever-expanding requirements of trade and transport.
The main causes of this industrial revolution were--the application of a number of inventions and improved processes to leading industries; the incalculable advantages derived from steam power; the immense increase in the supplies of cotton, coal, minerals and other raw materials; the greater wealth of the nation, allowing of much more capital being available for industrial enterprises; and the improvement, not alone in inland communication, but in ship-building and the art of navigation, foreign markets being thus reached more readily at a time when the general political and economic conditions were especially favourable to the commercial expansion abroad which followed on our industrial expansion at home.
Woollen manufactures, originally established here with the help of workers introduced from Flanders in the time of Edward III., had had a long pre-eminence, obtaining a vested interest which led to the advent of a new rival, in the form of cotton manufacturers, receiving, at first, very scanty encouragement. Woollens had made such progress that, even before the Restoration, a market was (as Dowell tells us) opened for our goods, not only in Spain, France, Italy and Germany, but also in Russia and Baltic and other ports, while they were carried by way of Archangel into Persia, and also made a market for themselves in Turkey. { 187}A great part of England was turned into sheep farms for the production of wool, and by 1700 the value of woollen goods exported had risen to £3,000,000.
