since the conclusion of the Franco-German war, and the consolidation of the German and Italian States, are now to be found in almost every European town of even secondary importance; and bridges and piers, in the construction of which iron has almost entirely superseded every other material. It is difficult to imagine what would have been the state of the iron industry in this country if we had been called upon to supply our full proportion of the enormously increased demand for iron. To meet that proportion, the British production of pig iron should have been close on 11,000,000 tons in 1882, a drain on our mineral resources which cannot be replaced, and which, especially if continued in the same ratio, would have been anything but desirable. Fortunately, as I am disposed to think, other countries have contributed more than a proportionate amount to the increase in the world's demand; and, paradoxical as it may appear, it is possible that, to this country at least, the encouragement given by protective duties to the production of iron abroad may have been a blessing in disguise. PROGRESS OF BESSEMER STEEL. To speak of the enormous increase in the production of steel by the introduction of the Bessemer process has become a commonplace on occasions like the present, and yet I doubt whether its real dimensions are generally known or remembered. In 1869 the manufacture of Bessemer steel had already acquired what was then looked upon as a considerable development in all the principal centers of metallurgical industry, except the United States, but including our own country, |
