Fourteen years have passed since the first edition of this book was published, and in revising it for this new edition I found at my disposal an immense mass of new materials, statistical and descriptive, and a great number of new works dealing with the different subjects that are treated in this book.

This verification permits me to affirm that the economical tendencies that I had ventured to foreshadow then have only become more and more definite since. Everywhere we see the same decentralisation of industries going on, new nations continually entering the ranks of those which manufacture for the world market. Each of these new-comers endeavours to develop, and succeeds in developing, on its own territory the principal industries, and thus frees itself from being exploited by other nations, more advanced in their technical evolution. All nations have made a remarkable progress in this direction, as will be seen from the new data that are given in this book.

And this movement will certainly result, not only in a much-needed increase of the productive
