purely national and economic considerations. But it is, as matters now
stand, a national question. And it must remain so for some time to come,
even if we are reproached with a narrow Mercantilist economics. The
admission of aliens is not yet a fundamental international _right_, or
_duty_; it is only an example of _comity_ within the family of nations.
And the matter must rest in this state of limbo until we develop some
institution or method of registering our sentiments of internationalism,
and especially of determining _international surplus_. As it is idle to
talk or dream of abolishing poverty until at least the concept of social
or national surplus is pretty clearly fixed and its realization either
actually at hand or fairly imminent, just so is it vain to expect an
international adjustment of the immigration problem on economic grounds
until the existence of an international surplus is demonstrated, and the
methods of apportioning it worked out.

How soon we may expect these things it is not our province to predict. It
is too early to pass final judgment on Professor Patten's dictum that
inter-racial coöperation is impossible without integration, and that races
must therefore stand in hostile relations or finally unite. But it is
perfectly apparent that we have a long way to travel before the path to
integration is cleared. Such assemblages as the First Universal Races
Congress which met in London in 1911 can do much to prepare the way. But
it must not be forgotten that the German representative at that Congress
pleaded for the maintenance of strict racial and national boundaries, and
summed up his plea in the rather ominous sentence: "The brotherhood of man
is a good thing, but the struggle for life is a far better one." Meanwhile
we need not anticipate serious international difficulties in the way of
the sliding-scale plan; for foreign governments are watching the tide of
immigration with mixed feelings. They welcome the two or three hundred
million dollars sent home annually by alien residents in the United
