view that every increase in the productive powers of the soil will supply the requisite conditions for an increase in the population. No. That is true up to a certain point only, for at least a portion of the increased produce of the soil will be consumed by the margin of increased demands caused by the steady rise in the standard of living. But even if these demands were to be curtailed to the narrowest limits possible and if at the same time we were to use all our available energies in the intenser cultivation, we should here reach a definite limit which is conditioned by the inherent nature of the soil itself. No matter how industriously we may labour we cannot increase agricultural production beyond this limit. Therefore, though we may postpone the evil hour of distress for a certain time, it will arrive at last. The first phenomenon will be the recurrence of famine periods from time to time, after bad harvests, etc. The intervals between these famines will become shorter and shorter the more the population increases; and, finally, the famine times will disappear only in those rare years of plenty when the granaries are full. And a time will ultimately come when even in those years of plenty there will not be enough to go round; so that hunger will dog the footsteps of the nation. Nature must now step in once more and select those who are to survive, or else man will help himself by artificially preventing his own increase, with all the fatal consequences for the race and the species which have been already mentioned.

It may be objected here that, in one form or another, this future is in store for all mankind and that the individual nation or race cannot escape the general fate.

At first glance, that objection seems logical enough; but we have to take the following into account:

The day will certainly come when the whole of mankind will be forced to check the augmentation of the human species, because there will be no further possibility of adjusting the productivity of the soil to the perpetual increase in the population. Nature must then be allowed to use her own methods or man may possibly take the task of regulation into his own hands and establish the necessary equilibrium by the application of better means than we have at our disposal to-day. But then it will be a problem for mankind as a whole, whereas now only those races have to suffer from want which no longer have the strength and daring to acquire sufficient soil to fulfil their needs. For, as things stand to-day, vast spaces still lie uncultivated all over the surface of the globe. Those spaces are only waiting for the ploughshare. And it is quite certain that Nature did not set those territories apart as the exclusive pastures of any one nation or race to be held unutilized in reserve for the future. Such land awaits the people who have the strength to acquire it and the diligence to cultivate it.

Nature knows no political frontiers. She begins by establishing life on this globe and then watches the free play of forces. Those who show the greatest courage and industry are the children nearest to her heart and they will be granted the sovereign right of existence.

If a nation confines itself to 'internal colonization' while other races are perpetually increasing their territorial annexations all over the globe, that nation will be forced to restrict the numerical growth of its population at a time when the other nations are increasing theirs. This situation must eventually arrive. It will arrive soon if the territory which the nation has at its disposal be small. Now it is unfortunately true that only too often the best nations--or, to speak more exactly, the only really cultured nations, who at the same time are the chief bearers of human progress--have decided, in their blind pacifism, to refrain from the acquisition of new territory and to be content with 'internal colonization.' But at the same time nations of inferior quality succeed in getting hold of large spaces for colonization all over the globe. The state of affairs which must result from this contrast is the following:

Races which are culturally superior but less ruthless would be forced to restrict their increase, because of insufficient territory to support the population, while less civilized races could increase indefinitely, owing to the vast territories at their disposal. In other words: should that state of affairs continue, then the world will
