"We have produced some effects," mused Zimmern, "which were not anticipated, and which have been calling forth considerable criticism. His Majesty sends me memorandums nearly every year, after he reviews the maternity levels, insisting that the feminine beauty of the race is, as a whole, deteriorating. And yet this is logical enough. With the exception of our small actor-model strain, the characteristics for which we breed have only the most incidental relation to feminine beauty. The type of the labour female is, as you have seen, a buxom, fleshly beauty; youth and full nutrition are essential to its display, and it soon fades. In the scientific strains it seems that the power of original thought correlates with a feminine type that is certainly not beautiful. Doubtless not understanding this you may have felt that you were discriminated against in your assignment. But the clerical mind with its passion for monotonous repetition of petty mental processes seems to correlate with the most exquisite and refined feminine features. Those scintillating beauties on the Free Level who have ever at their beck our wisest men are from our clerical strain,--but of course they are only the rejects. It is unfortunate that you cannot see the more privileged specimens in the clerical maternity level. "But I digress to that which is of no consequence. The beauty of women is unimportant but the number of women is very important. When some women were specialized for motherhood then there were surplus women. At first they made workers of them. The war was then conducted on a larger scale than now. We had not yet fully specialized the soldier class. All the young men went to war; and, when they came back and went to work, they became bitterly jealous of the women workers and made an outcry that those who could not fight should not work. The men workers drove the women from industry, hoping thereby each to possess a mistress. As a result the great number of unproductive women was a drain upon the state. All sorts of schemes were proposed to reduce the number of female births but most of these were unscientific. In studying the records it was found that the offspring of certain men were predominantly males. By applying this principle of selection we have, with successive generations, been able to reduce the proportion of female births to less than half the old rate.
