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.
