All that has been said regarding Chinese immigration applies to Asiatic immigration in general. It is not surprising, therefore, that since the Japanese laborers have begun to come to us in large numbers the people of the Pacific Coast should demand the exclusion of the Japanese immigrants. While Japan has not the immense population of China and while the Japanese are perhaps a more adaptable people than the Chinese, still it would seem that in the main the people of the Pacific Coast are justified in their fears of the results of a large Japanese immigration. For the peace of both countries and of the world, therefore, it is to be hoped that the flow of Japanese laborers into the Western states will be checked without any disruption of the friendship of the United States and Japan. The same thing can be said regarding the Hindoo immigrants who are just beginning to come to us. It would appear that the wisest policy, therefore, regarding, all Asiatic immigration is the exclusion of Asiatic laborers, and as these would constitute over nine tenths of all Asiatic immigrants who might come to us, this would assure a practical solution of the problem.

CHAPTER X THE NEGRO PROBLEM Already we have been brought in our study of the immigration problem to race problems--problems of the relations of races to one another and of their mutual adjustment. The negro problem is one of many race problems which the United States has, but because it is the most pressing of all of our race problems it is frequently spoken of as _the race problem_. An unsolved factor in all race problems is the biological influence of racial heredity, and this factor we must seek to understand and estimate at the very outset of any scientific study of the negro problem.
