So Mrs. Bobbsey decided to call on her old friend, whom she had not seen for many years. She said she would take Flossie and Freddie with her. Nan and Bert were going to a moving picture show with another boy and girl and the latter's mother.

Mrs. Robinson lived on the east side of New York, in what is called an apartment house. Some called them tenements, and in them many families are crowded together, for room is very valuable in the big city of New York.

After Mrs. Bobbsey had talked for a while with her former girlhood friend, Flossie and Freddie, who had been sitting still in the parlor, asked if they could not go out in the street and watch the other children at play.

"Yes, but don't go off the steps," said their mother.

The two Bobbsey twins promised, but something happened that made them forget. This was the sight of a red-haired, snub-nosed boy, driving a goat, hitched to a small wagon, up and down the street.

"Oh, look at that!" cried the excited Freddie. "Isn't that great!"

"It's cute," said Flossie. "I wonder if he'd give us a ride?"

"Let's ask him," said Freddie. "I've got ten cents. Maybe he'd ride us for that. Come on!"

And so, forgetting all about their promise not to go off the steps of the apartment house where their mother's friend lived, the two small Bobbsey twins hurried down to look at the goat.
