[142] "The accumulations of racial experience tend to show," remarks Woods Hutchinson ("Animal Marriage," Contemporary Review, October, 1904), "that by the production of a smaller and smaller number of offspring, and the expenditure upon those of a greater amount of parental care, better results can be obtained in efficiency and capacity for survival."

[145] It is interesting to observe how Lafcadio Hearn, during the last years of his life, was compelled, however unwillingly, to recognize this change. See e.g. his Japan: An Attempt at Interpretation, 1904, ch. XXI, on "Industrial Dangers." The Japanese themselves have recognized it, and it is the feeling of the decay of their ancient ideals which has given so great an impetus to new ethical movements, such as that, described as a kind of elevated materialism, established by Yukichi Fukuzawa (see Open Court, June, 1907).
