“Now you have hit it, my little man,” answered the big policeman. “I try to be a big brother to the people along the streets.”

By this time it was almost dark, but Bobby and Betty were now nearly home.

“Do you know this street?” asked the policeman.

“Oh, yes,” cried Bobby. “We live just around the corner.”

Bobby and Betty almost ran the last few steps of the way.

They were soon at the door.

They could not wait for the policeman to ring the bell.

They opened the door and ran straight to Mother.

They threw their arms around her.
