In the autumn all the swallows fly away to warm countries, but if one happens to be belated, it feels the cold so much that it falls down like a dead thing, and remains lying where it falls till the snow covers it up. Thumbelisa quite shook with fright, for the bird was very, very big beside her, who was only one inch high; but she gathered up her courage, packed the wool closer round the poor bird, and fetched a leaf of mint which she had herself for a coverlet, and laid it over the bird's head. The next night she stole down again to it and found it alive but so feeble that it could only just open its eyes for a moment to look at Thumbelisa who stood with a bit of tinderwood in her hand, for she had no other lantern.
"Many, many thanks, you sweet child," said the sick swallow to her; "you have warmed me beautifully. I shall soon have strength to fly out into the warm sun again."
"Oh!" said she, "it is so cold outside, it snows and freezes, stay in your warm bed, I will tend you." Then she brought water to the swallow in a leaf, and when it had drunk some it told her how it had torn its wing on a blackthorn bush, and therefore could not fly as fast as the other swallows which were taking flight then for the distant warm lands. At last it fell down on the ground, but after that it remembered nothing and did not in the least know how it had got into the tunnel.
It stayed there all the winter, and Thumbelisa was good to it and grew very fond of it. She did not tell either the mole or the field-mouse anything about it, for they did not like the poor unfortunate swallow.
As soon as the spring came and the warmth of the sun penetrated the ground, the swallow said good-bye to Thumbelisa, who opened the hole which the mole had made above. The sun streamed in deliciously upon them, and the swallow asked if she would not go with him; she could sit upon his back and they would fly far away into the green wood. But Thumbelisa knew that it would grieve the old field-mouse if she left her like that.
