when I was younger. I
don't believe I could climb that tree and get him now."

"Do you want me to do it for you, mister?" asked a new voice.

Bunny, Sue, and the other children turned to see who had spoken. They
saw a boy about twelve years old, with bright, shining eyes standing
beside Mr. Winkler and pointing up at the monkey in the tree. The
strange boy seemed to have arrived on the scene very suddenly.

"Do you want me to climb the tree and get your monkey for you?" asked
the boy. "I'll do it, if he doesn't bite."

"Oh, he doesn't bite--Wango is very gentle," said Mr. Winkler. "But can
you climb that high tree?"

"I've climbed higher ones than that," was the answer. "And ropes and
poles and the sides of buildings. I can climb almost anything if I can
get a hold. I'll go up and get the monkey for you!"

As he spoke he took off his coat; and though the day was cold Bunny
noticed that the strange boy wore no overcoat. Hanging his jacket on a
low limb of the tree which held Wango, the boy began to climb. And, as

CHAPTER V

A COLD LITTLE SINGER

Bunny Brown was so excited in watching to see how the strange boy would
climb up and get the monkey that, at first, he paid little attention to
what Sue said. The boy by this time was beginning to scramble up the
trunk of the tree. Sitting on a branch, high above the lad's head, was
Wango the monkey, eating the piece of cake.

"It's the very same boy, I know it is!" declared Sue.

"What same boy?" asked Sadie West, while the other boys and girls
watched the climber.

"The same one who was with the little girl that sang songs in the Opera
House show. Don't you remember, Bunny?" asked Sue.

This time Bunny not only heard what his sister said, but he paid some
attention to her. And, noting that the climbing boy was half way up the
tree now, Bunny turned to Sue and asked her what she had said.

"This is the number three time I told you," she answered, shaking her
head. "That's the boy from the show in the Opera House!"

Bunny looked closely at the climbing lad.

"Why, so it is!" he cried. "Look, Charlie--Harry--that's the acrobat
from the show!"

The boy in the tree was in plain sight now, over t
