Their supper was brought in at six o'clock.

Knowing that they would not be visited again until the morning, they at once began work.
As soon as they had finished cutting one rivet they tried the bar, and their united strength was quite sufficient to bend it far enough to allow it being withdrawn from the rivet; then, throwing their weight upon it, it turned upon the bolt at the other end, until it hung perpendicularly.

In another half hour the other two bars were similarly removed, and the heavy shutters opened.

They were closed again, until their preparations were complete.
First they ate their supper, then sat and talked until nine.

Then they knotted their sheets together, and tied the underclothes into bundles.
