"And I doubt," he continued, after a little hesitation, "I doubt whether these sons of the new conditions will have much vitality. They are the children of lust on the father's side, worse still, of tired lust. It does make a difference. Perhaps if we were a young and vigorous people like the old Jews the seed would be strong enough to override any inherent weakness. But we are not, we are an old civilization. Before the plague, we had come to a consideration of eugenics. It had been forced upon us. A vital and growing people does not spend its time on such a question as that. Eugenics was a proposition that grew out of the necessity of the time. It was easy enough to deny decadence, and to prove our fitness by apparently sound argument, but, to me, it always seemed that this growing demand for some form of artificial selection of parents, by restriction of the palpably unfit, afforded the surest evidence. Things like that are only produced if there is a need for them. Eugenics was a symptom." Eileen sighed. "And what about us?" she asked. "We're happy," replied Jasper. "Probably the happiest people in the world at the present time. And we must try to give some of our happiness to others. We must go back to Marlow and work for the community. And I think we'll try in our limited way to do something for the younger generation. Perhaps, it might be possible for us to go north and try our hands at making steel, there are probably women there who would help us. But I don't think it's worth while, unless to preserve our knowledge and hand it on. We can only lessen the difficulty in one little district for a time. As the pressure of necessity grows, as it must grow, we shall be forced to abandon manufacture. The need for food will outrun us. We are too few, and it will be simpler and perhaps quicker to plough with a wooden plough than to wait for our faulty and slowly-produced steel. The adult population, small as it is, must decrease, and I'm afraid it will decrease more rapidly than we anticipate, owing to these causes of depression and lack of stimulus...." "Oh, well," said Eileen at last, getting to her feet, "we're happy, as you say, and our job seems pretty plain before us. To-morrow, I suppose, we ought to be getting back, though I hate taking the news to Elsie." Jasper came and stood beside her, and put his arm across her shoulders. "We, at any rate, must keep our spirits up," he said. "That, before everything." "I'm all right," said Eileen, brightly. "I've got you and, for the moment, the sea. We'll come back here sometimes, if the roads don't get too bad." "Yes, if the roads don't get too bad." "And, already, the briars are creeping across the road from hedge to hedge. The forest is coming back." "The forest and the wild." He drew her a little closer and they stood looking out towards the horizon. 3 In the south-west the clear line had been wiped out and what looked like mist was sweeping towards them.
