THE MIGRATION OF POPULATIONS 87

engines of destruction, with which one people may

To revert now more directly to the part that the 
migration of populations can play in bettering the 
world’s future and making it possible to carry a larger 
number. It is evident, from the issues just referred 
to, that the question is complicated by the divided 
interests of the human race, and by the limitations 
involved in the egoistic view which is characteristic, 
not merely of individuals, but also of communities and 
nations. Some matters present themselves for con-

quite clearly that peoples will have to consider the 
migration question whether they will or no; and they 
will be well advised if this is done with the world- 
facts before them, and not from a narrow standpoint. 
There can be no evading of the real question, viz., 
that world-conditions are such that the rights of all 
peoples will have to be equitably considered, if the 
world desires peace. This involves the full considera- 
tion of the admixture of peoples who have attained to 
very different degrees of culture or civilisation, and it 
is full of difficulty. 
It has lately been pointed out by the Very Rev. 
Dean Inge that it is possible for immigration to have 
a very bad effect on the development of a people,! and 
that in certain cases it may be “ politically and racially 
wise ” to prevent it. The unrestricted influx into a 
country of low-grade citizens from other countries

possible aggregate of the populations of the countries 
concerned. No country whatever should be ready to
