the
casing inside, thrust one foot carefully out. Oh, joy! she touched the
roof, and with one fearful step was safely on it, though her heart
beat a little hard.

The sun shone brightly, and she was almost too happy to look about to
see her new possessions. The roof was flat, as large as a big room; on
one side was a tall brick chimney and in the middle a queer-looking
structure which she at once went over to examine. It was shaped like a
tent, and all made of windows which she could not see through because
they were of colored glass.

Both sides of this roof-room were tall, brick walls of neighboring
buildings, and in the front a lower one, which was, however, too high
for her to look over. Only the back was open.

It was not a very attractive place, but to Molly it was a new world.
She was a strange child always, full of imagination, and she at once
decided that the brick chimney was a castle in which some children
were shut up, and the window tent looked into a garden where they were
allowed to play.

She resolved to bring her doll out here, and she thought she should
never be lonely again if she could only find a peep-hole in that glass
roof and look down into the garden; so she was always looking for one.

After that day she spent all her time--when it did not rain--on the

dolls with their furniture and things, her sisters keeping her well
supplied so that she should not be lonely. She found a small box which
she could leave out there, and made her a nice seat, and soon she
began to get rosy and happy again, to the great delight of her
sisters.

Every day, as soon as she was left alone, she pushed up the window,
took that fearful step on which, if she had slipped or lost her hold,
she would have been dashed to pieces on the pavement below, and then
spent the day happily with her dolls and toys, making stories for
herself.

It was not long before she found the peep-hole she was always looking
for into the room under the glass tent--for it was a room, and not a
garden, as she hoped. This peep-hole was a small three-cornered piece
of clear glass among the colored, and through it she could see
everything in the room below.

The room was not particularly interesting, but she made up a story
about it as she always did. It seemed to be a gentleman's office, for
an elderly gentleman nearly always sat at a table under the
roof-window and had pap
