"Very well; then let me advise you to be quick in making your preparations. I shall call again this day week, and expect to find you are standing, like the swallows, ready for flight. Look at them now on the coping of the old wall, talking about their departure, and settling."

When Dr. Bell was gone, Mrs. Acheson sat quietly by the fire, thinking over what he had said. She had tried to persuade herself that her cough was better, that if she kept in the house all the winter it would go away. She had felt sure that in this comfortable room, out of which her bed-room opened, she must be as well as in Italy or the south of France. Dr. Bell was so determined to get his own way, and it was cruel to turn her out of her home. And then Dorothy, little Dorothy! how hard it would be for her to leave Puff and Muff, and her nursery, and everything in it. And what was to be done about Nino, the little white poodle, and——

A host of objections started up, and Mrs. Acheson tried to believe that she would make a stand against Dr. Bell, and stay in Canon's House all the winter.

Meantime little Dorothy, who had been lying curled up as I have described, had heard in a confused way much of what Dr. Bell said. "A flight with the swallows." The swallows, her uncle, Canon Percival, had told her, flew away to sunshine and flowers; that the cold wind in England gave them the ague, and that they got all sorts of complaints, and would die of hunger, or cramp, or rheumatism if they stayed in England!

"As easy a journey as if you were on a swallow's back," the doctor had said; and Dorothy was wondering who could be small enough to ride on a swallow's back, when she heard a tap at the window, a little gentle tap.

"Let me in, let me in," said a small voice, which was like a chirp or a twitter, rather than a voice.

And then Dorothy turned the old-fashioned handle which closed the lower square of the lattice window, and in came the swallow. She recognised it as one she knew—the mother-bird from the nest in the eaves.

"Come to the sunny South," it said. "Come to the sunny South."

"I can't, without mother," Dorothy said.

"Oh yes, you can. Get on my back."
