st have died some time ago," said Aunt Lu
in a whisper to Mrs. Brown. "She probably didn't have any _real_ folks
down South, so whoever she was with sent her up here."

"Well, I'm glad you took care of her," said Mrs. Brown. "She looks like
a nice clean little girl."

"She is; and she is very kind and helpful. She is careful, too, and she
will be a help with Bunny and Sue. Wopsie has already learned her way
around that part of New York near my apartment, and I can send her on
errands. She can take Bunny and Sue out."

While Mrs. Brown and Aunt Lu were talking together Wopsie had given
Bunny and Sue some sweet crackers from a box she took out from a pocket
in the side of the automobile. Aunt Lu had told her to do so. So Bunny
and Sue ate the crackers as they rode along, and Wopsie sat near them.

"Don't you want a cracker?" asked Bunny.

"No, sah, thank you," answered the little colored girl. "I don't eat
'tween meals. Miss Baker say as how it ain't good for your
intergestion."

"What's in--indergaston?" asked Sue.

"Huh! Dat's a misery on yo' insides--a pain," said Wopsie. "I t'ought

Bunny was silent a minute.

"Do you know how to stop a train by pulling on the whistle cord?" he
asked.

"No," said Wopsie.

"Huh! I thought everybody knew that!" exclaimed Bunny. Then he laughed,
as Wopsie did. It was a little joke on her, when Bunny answered her the
way he did.

The automobile came to a stop in front of a large building. Bunny and
Sue looked up at it.

"My! What a big house you live in, Aunt Lu!" said Bunny.

"Oh, this isn't all mine!" laughed Aunt Lu. "There are many others who
live in here. This is what is called an apartment house. I have my
dining room, kitchen, bath room and other rooms, and other families in
this building have the same thing. You see there isn't room in New York
to build separate houses, such as you have in Bellemere, so they make
one big house, and divide it up on the inside, into a number of little
houses, or apartments."

Bunny and Sue thought that very strange.

"But you haven't any yard to play in!" exclaimed Bunny, as he and his
sister got out of the automobile, and found that the front door of Aunt
Lu's apartment was right on the sidewalk.

"No, we don't have yards in the city, Bunny. But we have a roof to go up
on and play."

"Playing on a roof!" cried Bunny. "I should think you'd fall off!"

"Oh, it has a high railing all around it. Wopsie m
