The sun pushed aside an intervening cloud and considered her with astonishment. “Is this why you so continually turn into a tree?” he said.

Phega was too desperate to consider the wonder of actually, at last, talking to the sun. She said, “All I do, I do in the remote, tiny hope of pleasing you and causing you to love me as I love you.”

“I had no idea,” said the sun, and he added, not unkindly, “but I do love everything according to its nature, and your nature is human. I might admire you for so skillfully becoming a tree, but that is, when all is said and done, only an imitation of a tree. It follows that I love you better as a human.” He beamed and was clearly about to pass on.

Phega threw herself down on the ground, half woman and half tree, and wept bitterly, thrashing her branches and rolling back and forth. “But I love you,” she cried out. “You are the light of the world, and I love you. I have to be a tree because then I have no heart to ache for you, and even as a tree I ache at night because you aren’t there. Tell me what I can do to make you love me.”

The sun paused. “I do not understand your passion,” he said. “I have no wish to hurt you, but this is the truth: I cannot love you as an imitation of a tree.”

A small hope came to Phega. She raised the branches of her head. “Could you love me if I stopped pretending to be a tree?”

“Naturally,” said the sun, thinking this would appease her. “I would love you according to your nature, human woman.”

“Then I make a bargain with you,” said Phega. “I will stop pretending and you will love me.”

“If that is what you want,” said the sun, and went on his way.

Phega shook her head free of branches and her feet from the ground and sat up, brooding, with her chin on her hands. That was how her mother’s servants found her and watched her warily from among the apple trees. She sat there for hours. She had bargained with the sun as a person might bargain for her very life, out of the desperation of her love, and she needed to work out a plan to back her bargain with. It gave her slight shame that she was trying to trap such a being as the sun, but she knew that was not going to stop her. She was beyond shame.

There is no point imitating something that already exists, she said to herself, because that is pretending to be that thing. I will have to be some kind that is totally new.

Phega came down from the hill and studied trees again. Because of the hope her bargain had given her, she studied in a new way, with passion and depth, all the time her father was away. She ranged far afield to the forests in the valleys beyond the manor, where she spent days among the trees, standing still as a tree, but in human shape—which puzzled her mother’s servants exceedingly—listening to the creak of their growth and every rustle of every leaf, until she knew them as trees knew other trees and comprehended the abiding restless stillness of them. The entire shape of a tree against the sky became open to her, and she came to know all their properties. Trees had power. Willows had pithy centers and grew fast; they caused sleep. Elder was pithy, too; it could give powerful protection but had a touchy nature and should be treated politely. But the oak and the ash, the giant trees that held their branches closest to the sun’s love, had the greatest power of all. Oak was constancy, and ash was change. Phega studied these two longest and most respectfully.

“I need the properties of both these,” she said.

She carried away branches of leafing twigs to study as she walked home, noting the join of twig to twig and the way the leaves were fastened on. Evergreens impressed her by the way they kept leaves for the sun even in winter, but she was soon sure they did it out of primitive parsimony. Oaks, on the other hand, had their leaves tightly knotted on by reason of their strength.

“I shall need the same kind of strength,” Phega said.

As autumn drew on, the fruiting trees preoccupied her, since it was clear that it was growth and fruition the sun seemed most to love. They all, she saw, partook of the natures of both oaks and elders, even hawthorn, rowan, and hazel. Indeed, many of them were related to the lowlier bushes and fruiting plants, but the giant trees that the sun most loved were more exclusive in their pedigrees.

“Then I shall be like the oak,” Phega said, “but bear better fruit.”

Winter approached, and trees were felled for firewood. Phega was there, where the foresters were working, anxiously inspecting the rings of the sawn trunk and interrogating the very sawdust. This mystified the servants who were following her. They asked the foresters if they had any idea what Phega was doing.

The foresters shook their heads and said, “She is not quite sane, but we know she is very wise.”

The servants had to be content with this. At least after that they had an easier time, for Phega was mostly at home in the manor examining the texture of the logs for the fires. She studied the bark on the outside and then the longwise grains and the roundwise rings of the interior, and she came to an important conclusion: an animal stopped growing when it had attained a certain shape, but a tree did not.

“I see now,” she said, “that I have by no means finished growing.” And she was very impatient because winter had put a stop to all growth, so that she had to wait for spring to study its nature.

In the middle of winter her father came home. He had found the perfect husband for Phega and was anxious to tell Phega and her mother all about the man. This man was a younger son of a powerful family, he said, and he had been a soldier for some years, during which time he had distinguished himself considerably and gained a name for sense and steadiness. Now he was looking for a wife to marry and settle down with. Though he was not rich, he was not poor either, and he was on good terms with the wealthier members of his family. It was, said Phega’s father, a most desirable match.

Phega barely listened to all this. She went away to look at the latest load of logs before her father had finished speaking. He may not ever come here, she said to herself, and if he does, he will see I am not interested and go away again.

“Did I say something wrong?” her father asked her mother. “I had hoped to show her that the man has advantages that far outweigh the fact that he is not in his first youth.”

“No—it’s just the way she is,” said Phega’s mother. “Have you invited the man here?”

“Yes, he is coming in the spring,” her father said. “His name is Evor. Phega will like him.”

Phega’s mother was not entirely sure of this. She called the servants she had set to follow Phega to her privately and asked them what they had found out. “Nothing,” they said. “We think she has given up turning into a tree. She has never so much as put forth a root while we are watching her.”

“I hope you are right,” said Phega’s mother. “But I want you to go on watching her, even more carefully than before. It is now extremely important that we know how to stop her becoming a tree if she ever threatens to do so.”

The servants sighed, knowing they were in for another dull and difficult time. And they were not mistaken because, as soon as the first snowdrops appeared, Phega was out in the countryside studying the way things grew. As far as the servants were concerned, she would do nothing but sit or stand for hours watching a bud, or a tree, or a nest of mice or birds. As far as Phega was concerned, it was a long fascination as she divined how cells multiplied again and again and at length discovered that while animals took food from solid things, plants took their main food from the sun himself. “I think that may be the secret at last,” she said.

This puzzled the servants, but they reported it to Phega’s mother all the same. Her answer was, “I thought so. Be ready to bring her home the instant she shows a root or a shoot.”
