But what reason, in heaven's name, would they have for staying here? Three people, marooned, growing old, dying one by one. There was no chance for Man's survival here. From the evidence about them, they had come to the conclusion that on this New Earth, in the tree of evolution, the bud to grow into a limb of primates had never formed.
She turned and looked at the tall, straight pines ahead of her. She saw the deciduous hardwoods, now gold and red, to one side of her. Behind her the lake was teeming with fish. The spicy smell of fall was all around her, and a stray breeze brought a scent of grapes she had overlooked when she was gathering all she could find to make a wine to pleasantly surprise the boys.
She thought of the flock of wild chickens which had learned to hang around the cabin for scraps of food, the grunting lazy pigs, grown quite tame, begging her to find their acorns for them, the nanny goat with two half-grown kids Lt. Harper had brought back from a solitary walk he had taken.
New Earth was truly a paradise—and all to be wasted if there were not Man to appreciate it truly.
A thought knocked at her mind, but she resolutely shut it out, refused it even silent verbalization.
Yet, while she stooped over again and busied her hands with stripping the rice from the stalks without cutting them on the sharp dry leaves, she found herself thinking about Mendelian law. Line breeding from father to daughter, or brother to sister—in domestic animals, of course—was all right in fixing desirable traits, providing certain recessives in both the dam and the sire did not thus become dominant.
"There, Katheryn Kittredge," she mumbled with satisfaction. "Assuming the responsibilities of domesticity has not made you forget what you learned."
But the danger of fixing recessives into dominants through inbreeding was even less with half-brothers and sisters. Now daughters by one—er—sire could be bred to another sire to get only a quarter relationship to a similar cross from the other father—er—sire. She must work it out with a stylus in smooth clay. The boys had preempted every scrap of paper for their pointless calculations. But she could remember it, and it would be valuable in breeding up a desirable barnyard stock.
Yet it was odd that she assumed two males and only one female!
