"There, in the old brick wall, was a tiny oak door!"

"The door to fairyland!" Una said to herself.

Then old Marie had called to her through the trees, and Una dropped the curtain of ivy and turned to meet her nurse with flushed cheeks and shining eyes, for had not Norah and Dan told her that only those who found the door to fairyland could enter in? They must not show it to others.

"I'll come by myself to-morrow," the little girl had thought to herself; and she sat up in bed the next morning with a little happy laugh of remembrance.

"I'll be in fairyland to-day," she whispered softly.

CHAPTER VI.

UNA ASKS A QUESTION.

That afternoon, as soon as dinner was over and Marie had settled herself for her afternoon nap, Una slipped through the gap in the fence—how well she knew it now!—and started off by herself to try and find again the door into Fairyland.

On she ran, until she came to a place where three paths met, and was uncertain which to take.

A yellow butterfly, dancing gaily along one of the paths, decided her, and Una followed it gleefully.

"Perhaps it's a fairy sent to meet me," she thought.

At last she came to the stump of a tree where Marie had rested, and from there she soon found her way to the old wall in which was the secret door.

It took her longer to find the door than the little girl had expected. The ivy grew so thickly over the wall that she had to walk quite a long way—pushing aside the branches and peering between the leaves—before she found the little door once more.

Then she pulled away the twisted branches of the ivy which had grown across the door, and turned the handle timidly.

For a moment she thought the door was locked; then she heard a queer sort of grating sound and something fell on the other side of the wall. Una pulled once more, and the door opened slowly towards her.

What the little girl saw on the other side of the wall was so lovely that she gave a gasp of delight, and then stood, quite still, looking through the small doorway.

As far as she could see was a long bower of lovely pink and white flowers. Hundreds of bees hummed amongst the blossoms; but to Una the buzzing sounded like hundreds of tiny voices, and she thought she heard the fairies talking.

"Fairies! Fairies!" she called softly. But no one answered, and very soon the little girl stepped through the doorway and walked down the apple-blossom path, looking from side to side to see if there were any fairies hiding near.

On she went, until the pink and white bower turned into a wide walk with masses of gay May flowers on either side, and this in turn ended in a big square garden with stone walks and bright flower-beds, and a fountain sparkling in the midst.

In the stone basin of the fountain were pretty gold and silver fish.

"Fairy fishes!" Una thought, for she had never seen goldfish before, and she was still bending over the basin when she heard a tap, tap, tap on the stone pathway, and, turning quickly, saw a very small, very old lady coming towards her.
