ile Una hunted for birds' nests
among the bushes, and added more blossoms to the already large bunch of
flowers she had picked as she came along.

She had wandered further away from old Marie than she knew, when she
came suddenly to a high, ivy-covered wall, and was able to go no
further.

On either side it stretched away from her. The little girl was not
able to see where the wall began or where it ended, and she thought
that this must be the end of the wood at last, for the wall was so high
that she could not see if trees grew on the other side of it.

Presently she began to hunt for birds' nests among the ivy--Tom had
told her once that wrens and robins often built in ivy-covered
walls--and then it was that she had made the wonderful discovery.

There, in the old brick wall, half hidden by the ivy, 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.

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 w
