"Another yet more potent effect of the new order in limiting foreign exchange is the general equalization of all nations which has long ago come about as to intelligence and the knowledge and practice of sciences and arts. A nation of to-day would be humiliated to have to import any commodity which insuperable natural conditions did not prevent the production of at home. It is consequently to such productions that commerce is now limited, and the list of them grows ever shorter as with the progress of invention man's conquest of Nature proceeds. As to the old advantage of coal-producing countries in manufacturing, that disappeared nearly a century ago with the great discoveries which made the unlimited development of electrical power practically costless. "But you should understand that it is not merely on economic grounds or for self-esteem's sake that the various peoples desire to do everything possible for themselves rather than depend on people at a distance. It is quite as much for the education and mind-awakening influence of a diversified industrial system within a small space. It is our policy, so far as it can be economically carried out in the grouping of industries, not only to make the system of each nation complete, but so to group the various industries within each particular country that every considerable district shall present within its own limits a sort of microcosm of the industrial world. We were speaking of that, you may remember, the other morning, in the Labor Exchange." THE MODERN DOCTOR'S EASY TASK.

"That is one of the sanitariums," replied the doctor, "which people go to who are in bad health and do not wish to change their climate, as we think persons in serious chronic ill health ought to do and as all can now do if they desire. In these buildings everything is as absolutely adapted to the condition of the patient as if he were for the time being in a world in which his disease were the normal type." "Doubtless there have been great improvements in all matters relating to your profession--medicine, hygiene, surgery, and the rest--since my day."
