figure moving along the path she was
looking at. She rubbed her eyes and looked again--the figure had
disappeared, but instead she saw clearly in the moonlight two
butterflies flitting about the same path, darting first backwards, then
forwards, as if inviting her to follow them.

"'If only I were a fly and could walk straight up a wall,' thought Lena,
'I'd really step up that curtain and see if I couldn't make my way into
that grotto,' and then she laughed to herself at the fancy--'as if any
one _could_ walk into a picture!' she said.

"And then it seemed to her that the butterflies melted into the
leaves--and there was no movement at all on the curtains.

"'It must have been the trembling of the moonlight that made me fancy
it,' Lena said to herself. And the next morning when she awoke she stood
up on tiptoe to examine the particular spot where she had seen these
curious things. It looked just the same as the other parts of the

from among the branches.

"She was so surprised that she thought she would ask Mrs. Denny if _she_

head. It was not till the next night that she remembered anything more
about them.

"For the next night, strange to say, she wakened again in the same
sudden way. And again the moonlight was shining right on the curtains,
and this time Lena felt more sure than the night before, that something
was moving about among the leaves and flowers and branches that seemed
to stand out so brightly.

"'Oh dear,' she thought to herself, 'I _do_ wish I could creep up quite
quietly and see if it is one of those monkeys that has got loose. Oh
please, Mr. Monkey, if you are a fairy, _do_ come down and fetch me,'
she added, laughing.

"But her laughter stopped suddenly. Almost as she said the words the
most curious sound reached her ears--at first it seemed like the buzzing
of lots and lots of flies, bluebot
