One of the tendencies, statistically verified, of the native family is its reduction in size. In the first place the circumference of the family circle has grown definitely smaller through the loss of those adventitious members, the maiden aunt and the faithful servant. The average number of adult females in the typical household is nowadays just one. The odd women are out in the world on their own; they no longer live “under the roofs” of their brothers-in-law. Miss Lulu Bett is almost an anachronism in 1920. The faithful servant has been replaced by the faithless one, who never by any chance remains long enough to become a familial appendage, or else she has not been replaced at all. Even “Grandma” has begun to manifest symptoms of preferring to be on her own. Thus the glory of the patriarchal household has visibly departed, leaving only the biological minimum in its stead. In the dwindling of this ultimate group lies the crux of the matter. The American grows less and less prolific, and panicky theorists can already foresee a possible day when the last 100 per cent. American Adam and the last 100 per cent. American Eve will take their departure from our immigrationized stage. It is providentially arranged--the maxim tells us--that the trees shall not grow and grow until they pierce the heavens; but is there any power on the job of preventing the progressive decline of the original Anglo-Saxon stock even to the point of final extinction? This is a poignant doubt in a country where the Anglo-Saxon strain enjoys a prestige out of all proportion to its population quota. The strain may derive what comfort it can from the reflection that the exit of the Indian was probably not due to birth control.
