The decade between 1830 and 1840 was, in the phrase of Herzog, "the cradle of the new epoch." In that decade several of the greatest inventions that have marked human progress were first brought to practical perfection. Prominent among these were ocean steam navigation, railroads, and telegraphs. [Footnote: Ploetz in his Epitome of History, instructively compares these inventions to the three great inventions or discoveries— the magnetic needle, gunpowder, and printing—that ushered in the Modern Age.] In the year 1830 Stephenson exhibited the first really successful locomotive. In 1836 Morse perfected the telegraph. In 1838 ocean steamship navigation was first practically solved.
The rapidity with which these inventions have been introduced into almost all parts of the world, partakes of the marvellous.
Within the last fifty years the continents have been covered with a perfect network of railroads, constructed at an enormous cost of labor and capital. The aggregate length of the world's steam railways in 1883 was about 275,000 miles, sufficient, to use Mulhall's illustration, to girdle the earth eleven times at the equator, or more than sufficient to reach from the earth to the moon. The continental lines of railways are made virtually continuous round the world by connecting lines of ocean steamers. Telegraph wires traverse the continents in all directions, and cables run beneath all the oceans of the globe.
By these inventions the most remote parts of the earth have been brought near together. A solidarity of commercial interests has been created. Thought has been made virtually cosmopolitan: a new and helpful idea or discovery becomes immediately the common possession of the world. Facilities for travel, by bringing men together, and familiarizing them with new scenes and different forms of society and belief, have made them more liberal and tolerant. Mind has been broadened and quickened. And by the virtual annihilation of time and space, governmental problems have been solved. The chief difficulties in maintaining a confederation of states widely separated have been removed, and such extended territories as those of the United States made practically as compact as the most closely consolidated European state. England, with her scattered colonies, may now, Professor Seeley thinks, well enough become a World Venice, with the oceans for streets. Furthermore, the steps of human progress have been accelerated a hundred-fold. The work of years, and of centuries even, is crowded into a day. Thus Japan, on the outskirts of the world, has been modified more by our civilization within the last decade or two, than Britain was modified by the civilization of Rome during the four hundred years that the island was connected with the empire.
But a still more important feature of the new epoch is the use of steam engines, electric motors, and machinery in the manufactures and the various other industries of mankind. At the beginning of the nineteenth century the great manufactures of the world were in their infancy. Under the impulse of modern inventions they have been carried to seeming perfection at a bound. New motors and improved machinery have increased incalculably the productive forces of society. This enormous augmentation of the power of production is one of the most significant features of the age.
The history of this wonderful age, so different from any preceding age, cannot yet be written, for no one can tell whether the epoch is just opening or is already well advanced. It may well be that we have already seen the greatest surprises of the age, and that the epoch is nearing its culmination, [Footnote: "It is probable," says Professor Ely, "that as we, after more than two thousand years, look back upon the time of Pericles with wonder and astonishment, as an epoch great in art and literature, posterity two thousand years hence will regard our era as forming an admirable and unparalleled epoch in the history of industrial invention." —French and German Socialism in Modern Times.] and that other than material development—let us hope intellectual and moral development—will characterize future epochs.
