If practical cooeperation becomes a part of our plan of international organization in the future, we shall see many problems in applied economics and industry taken up for far more serious consideration than has been possible hitherto. Some of these problems, attacked even on a national scale, have seemed hopeless, but when viewed in their international aspects and with a prospect of international interest and effort they seem very different. There are many such problems toward the solution of which education must contribute a large part. We might mention the food problem of the world as typical, and point to the present world-wide interest and cooeperation as an indication of what may come in the future in regard to all the problems of production and distribution of necessities, _if_ we really mean anything by our internationalism. Apparently we hold within our hands the means of alleviating most, if not all, the destitution of the world. Organization and education in efficiency are the necessary and the sufficient weapons. So we may conclude that an efficient method of educating peoples in the work of food production, and in the habit of conserving necessities would make a wide change in the economic condition of the world. Organization which shall include in some way the service of all children, will add still more to efficiency, and will contribute an educational factor of great importance. In such ways we may to an unlimited extent increase the available energies of the world, and make possible, if we will, the further increase and expansion of the human race. Such a possibility and such an ideal give a totally new meaning to much of the fundamental work of education. All our departments and accessories of the educational system that have anything to do with the elemental occupations acquire a new interest and importance from this point of view.
