As soon as spring came and the sun warmed the earth, the swallow told Thumbelina it was time to say good-by. She reopened the hole that the mole had made in the ceiling, and the sun shone in splendor upon them. The swallow asked Thumbelina to go with him. She could sit on his back as they flew away through the green woods. But Thumbelina knew that it would make the old field mouse feel badly if she left like that, so she said:
"No, I cannot go."
"Fare you well, fare you well, my good and pretty girl," said the swallow, as he flew into the sunshine. Tears came into Thumbelina's eyes as she watched him go, for she was so fond of the poor swallow.
"Chirp, chirp!" sang the bird, at he flew into the green woods.
Thumbelina felt very downcast. She was not permitted to go out in the warm sunshine. Moreover, the grain that was sown in the field above the field mouse's house grew so tall that, to a poor little girl who was only an inch high, it was like a dense forest.
"You must work on your trousseau this summer," the field mouse said, for their neighbor, that loathsome mole in his black velvet coat, had proposed to her. "You must have both woolens and linens, both bedding and wardrobe, when you become the mole's wife."
Thumbelina had to turn the spindle, and the field mouse hired four spiders to spin and weave for her day and night. The mole came to call every evening, and his favorite remark was that the sun, which now baked the earth as hard as a rock, would not be nearly so hot when summer was over. Yes, as soon as summer was past he would be marrying Thumbelina. But she was not at all happy about it, because she didn't like the tedious mole the least bit. Every morning at sunrise and every evening at sunset, she would steal out the door. When the breeze blew the ears of grain apart she could catch glimpses of the blue sky. She could dream about how bright and fair it was out of doors, and how she wished she would see her dear swallow again. But he did not come back, for doubtless he was far away, flying about in the lovely green woods.
