Let us imagine similar schools in every country. Young men and girls, sent abroad to follow up the course of study they have begun in their own country, would find the completion of their education in the mental intercourse offered by contact with the boys and girls of the foreign school. They would by this means widen the horizon of their ideas, they would become cosmopolitan without effort, reap such advantages from foreign life as would greatly add to the force of their own personality, and return home with an equipment of sound judgment and self-possession. In addition, they would have learnt the foreign languages so necessary to the pursuit of commerce, manufacture, letters, and the arts. The young man and the girl thus educated in the idea of world-relationship would hold their own in the circles to which they belonged, and would be certain to do their country good service at an age when, in the ordinary course of things, they might dream of going abroad for the sake of seeing the world, without any ability to profit by that exchange of ideas and comparison of manners which the international school would secure to them just at the impressionable age. When one considers how useless in most cases, and how invariably costly to parents, travelling is in the case of young men destined for professional or even commercial careers, when undertaken after their education is completed, one must acknowledge the advantage which would result from the exchange between the countries of young, amenable pupils, quick to assimilate all the elements needed for complete training. Of course each student sent abroad would have professors of his own tongue and race to continue the course of study he was pursuing at home. But from the very fact that they were living in a foreign land, they would be able to learn the new language outside the classroom without any trouble, and become initiated in new ways and ideas, acquiring all sorts of useful knowledge, which would help to mature their minds. So would each one, without losing contact with his own land, profit by the constant recurrence of matters for comparison and analysis.
