m and was expecting them.

"Now, just sit right down here and be comfortable," the agent said to the
Bobbsey twins. "You'll be all right, and your folks will soon come for
you. I have to sit in the office and sell tickets."

The kind woman called a good-bye to the children and went away; so Flossie
and Freddie were left by themselves in the elevated railroad station at
One Hundred and Twenty-fifth Street.

For a while they sat quietly, watching the people come in to buy tickets
or get off trains. The agent did not pay much attention to them, being
very busy, for it was toward the close of day when the rush was like the
morning, greater than at other times.

"Say! What's that?" suddenly asked Flossie, holding up her chubby hand to
tell Freddie to stop whistling, which he was trying to do.

"What's what?" he asked, looking at his sister.

"I hear music," went on Flossie.

"So do I!" exclaimed Freddie.

They both listened, and from somewhere outside they heard the sound again.

"It's a hand organ!" cried Flossie.

"No, it's a hand _piano!_" said Freddie. "Hear how jiggily the tune is."

"Well, it's the same thing," Flossie insisted, "I wonder if there's a

to do. They looked toward the little office in which the ticket seller had
shut himself. He was busy selling tickets.

"He'll not see us," whispered Freddie. "Besides, we're coming right back
as soon as we see the monkey."

"And we'll give him some peanuts," added Flossie. "You can buy some with
your five cents, Freddie. And we won't give them _all_ to the monkey. I
want some."

"So do I. Come on, we'll go down."

The agent seemed to have forgotten them. At any rate his door was closed
and he could not see them. None of the passengers, hurrying in to buy
tickets, paid any attention to the Bobbsey twins. So, hand in hand,
Flossie and Freddie went out of the station, and down the long stairs to
where they could hear the music of the hand piano.

It was being played by an Italian man in the street, almost under the
elevated station, and, as Flossie leaned over the stair railing to look
down, she cried out:

"Oh, there is a monkey, Freddie! The man has it on a string!"

"That's good. Do you see peanuts anywhere?"

"Yes, there are some at
