“I am sorry,” said Tina.

The little girl leaned over and touched her with the rose, and at once she was on the other side.

They went on, picking their way through the mud, till they came to a large hole in the side of a hill. There was a heavy stone rolled up in front of it.

The little girl took the rose, and lightly tapped with it, saying:

“Kitty-cat! Kitty-cat!

Some one is here;

Two times, or three times,

You need have no fear.”

The heavy stone was rolled away, and they went into what seemed a long, winding passage. It grew darker and darker as they went on.
