s furnished a little more comfortably for a woman.

The moon had set, but they were now so used to the darkness that with
the little starlight that penetrated through the barred windows they
were able to see quite well. They went at once to the wall directly
opposite and began an eager search for a diamond-shaped stone. There was
none, nor was there any big slab-like stone resembling the revolving one
in the wall through which they had just passed. They tried the other two
walls, but also without avail. It was evident that only these two cells
were connected.

"Well, Miss Juanita," said Harry, when they had assured themselves that
there was no other opening, "we have only succeeded in widening our
prisons. There is no other means of exit but the doors. I am very sorry
to have raised your expectations."

The girl, who had followed them eagerly from place to place as they
examined the walls, held out her hands in protest at Harry's words.

"Oh, let me thank you for the ray of happiness you have brought me," she
said, quickly.

fear that is very little."

"Good-night, my friends."

"Now I wonder how the old stone works backwards?" said Harry, when they
had returned to their own room.

"Press the button and the stone will do the rest," said Bert, with a
grim attempt at humor. He pressed the diamond-shaped stone as he spoke,
but there was no answering creak, nor did the slab move.

"It is not likely that the same spring does double duty. We will have to
hunt up the other," said Harry. "Now, by all the laws of symmetry there
should be another similar stone on the other side of the slab--and here

He pushed on this as he spoke, and at once the grinding sound began
