"There may have been a time when an anti-Japanese land bill would have limited Japanese immigration. But such a law would be impotent now to keep native Japanese from possessing themselves of the choicest agricultural and horticultural land in California. For there are now more than 30,000 children in the State of Japanese parentage, native-born; they possess all the rights of leasing and ownership held by white children born here.... The birth statistics seem to prove that the danger is not from the Japanese soldiers, but from the picture brides. The fruitfulness of those brides is almost uncanny.... Here is a Japanese problem of sufficient gravity to merit serious consideration. We are threatened with an over-production of Japanese children. First come the men, then the picture brides, then the families. If California is to be preserved for the next generation as a 'white man's country' there must be some movement started that will restrict the Japanese birth-rate in California. When a condition is reached in which two children of Japanese parentage are born in some districts for every white child, it is about time something else was done than making speeches about it in the American Senate.... If the same present birth-ratio were maintained for the next ten years, there would be 150,000 children of Japanese descent born in California in 1929 and but 40,000 white children. And in 1949 the majority of the population of California would be Japanese, ruling the State."[182] The alarm of our California contemporary may, in this particular instance, be exaggerated. Nevertheless, when we remember the practically unlimited expansive possibilities of even small human groups under favorable conditions, the picture drawn contains no features inherently impossible of realization. What is absolutely certain is that any wholesale Oriental influx would inevitably doom the whites, first of the Pacific coast, and later of the whole United States, to social sterilization and ultimate racial extinction. Thus all those newer regions of the white world won by the white expansion of the last four centuries are alike menaced by the colored migration peril; whether these regions be under-developed, under-populated frontier marches like Australia and British Columbia, or older and better-populated countries like the United States.
