"But the sexual impulse of the labourers made them restless and rebellious, and the support of the free women for these millions of workers was a great economic waste. When animals had been bred to large size and great strength their sexuality had decreased, while their power as beasts of burden increased. The same principle applied to man has resulted in more docile workers. By beginning with the soldiers and mine workers, who were kept away from women, and by combining proper training with the hereditary selection, we solved that problem and removed all knowledge of women from the minds of the workmen." "But how about paternity among the workers?" I asked. "Those who are selected are removed to special isolated quarters. They are told they are being taken to serve as His Majesty's body guard; and they never go back to mingle with their fellows." I then related for the doctor my conversation with the workman who asked me about women. "So," said Zimmern, "there has been a leak somewhere; knowledge is hard to bottle. Still we have bottled most of it and the labourer accepts his loveless lot. But it could not be done with the intellectual worker." Dr. Zimmern smiled cynically. "At least," he added, "we don't propose to admit that it can be done. And that, Col. Armstadt, is what I was remarking about the other evening. Unless you chemists can solve the protium problem, Germany must cut her population swiftly, if we do not starve out altogether. His Majesty's plan to turn the workmen into soldiers and make workers of the free women will not solve it. It is too serious for that. The Emperor's talk about the day being at hand is all nonsense. He knows and we know that these mongrel herds, as he calls the outside enemy, are not so degenerate. "We may have improved the German stock in some ways by our scientific breeding, but science cannot do much in six generations, and what we have accomplished, I as a member of the Eugenist Staff, can assure you has really been attained as much by training as by breeding, though the breeding is given the credit. Our men are highly specialized, and once outside the walls of Berlin they will find things so different that this very specialization will prove a handicap. The mongrel peoples are more adaptable. Our workmen and soldiers are large in physique, but dwarfed of intellect. The enemy will beat us in open war, and, even if we should be victorious in war, we could not rule them. Either we solve this food business or we all turn soldiers and go out into the blinding sunlight and die fighting." I ventured as a wild remark: "At least, if we get outside there will be plenty of women."
