It was a rather simple affair, since the rope that was attached to the top of the curtain was tied to the log, and when the log was made to drop the curtain went up.

It would drop just as quickly when released, as there was a weight at the bottom.

The part of the cave the three men were now in was hardly any wider than the entrance itself, but it extended back a short distance and then took a sharp turn to the left.

Though irregular in shape, it was surely an ideal place for a band of robbers to hold forth.

The natural ceiling was high, and through the face of the cliff light was admitted through several zig-zag cracks.

Fully a dozen men were sitting in the cave on boxes and stools or lying in bunks that were built along two sides of it, and none of them appeared to be much disturbed by the entrance of the trio.
