If the inventions of the nineteenth century have made possible emigration to such an extent to-day as never before existed, it has still more facilitated inter-migration. It has almost destroyed the equilibrium between the centripetal and centrifugal forces, giving the advantages to the latter. The facilities of locomotion have made people restless; the times have passed by when grandchildren would live in the same house in which their grandparents lived or when they consider it a hardship and misfortune to move out of such a habitation, or to see it change owners; time has been, when only the adventurer left his native place, and when it was considered dangerous to go into the world, which at that time could be circumscribed by a radius of a few miles; time has been, when people lived for generations in the same house, in the same street, in the same village or town, when even the household furniture became venerable on account of its antiquity and the remembrances connected with it. What boy or girl in our day plays around the chair which their great-grandfather used to occupy? To sell one house and move into another; to leave one city and seek settlement in another, is now the rule and not the exception; and it is mainly this inter-migration, stirring up the masses, to which is due our increased prosperity and our progress in all branches of knowledge. Inter-migration keeps us from stagnation; it removes shyness and fear at the sight of a stranger, accustoms us to an intercourse with different people, removes prejudices and superstitions, and facilitates the exchange of thoughts and ideas. On the other hand, it cannot be denied that intermigration has also its drawbacks; that it will easily flood the labor market so as to screw down wages; it will foster the venturesome spirit, induce people to risk a certainty for an uncertainty, and especially has it tended to draw people from the rural districts to the large cities.
