The boys saw another place in a room beyond, which was in some respects still more dreadful than this. It was a place where there was an opening in the floor, near the wall of the room, that looked like a trap door. There was the beginning of a stone stair leading down. A small railing was built round the opening, as if to keep people from falling in. The boys all crowded round the railing, and looked down.
They saw that the stair only went down three steps, and then it came to a sudden end, and all below was a dark and dismal pit, which seemed bottomless. On looking more intently, however, they could at length see a glimmer of light, and hear the rippling of the waves of the lake, at a great depth below. The guide said that this was one of the oubliettes, that is, a place where men could be destroyed secretly, and in such a manner that no one should ever know what became of them. They were conducted to this door, and directed to go down. It was dark, so that they could only see the first steps of the stair. They would suppose, however, that the stair was continued, and that it would lead them down to some room, where they were to go. So they would walk on carefully, feeling for the steps of the stair; but after the third there would be no more, and they would fall down to a great depth on ragged rocks, and be killed. To make it certain that they would be killed by the fall, there were sharp blades, like the ends of scythes, fixed in the rock, far below, to cut them in pieces as they fell.
It seems these tyrants, hateful and merciless as they were, did not wish, or perhaps did not dare, to destroy the souls as well as the bodies of their victims, and so they contrived it that the last act which the poor wretch should perform before going down into this dreadful pit should be an act of devotion. To this end there was made a little niche in the wall, just over the trap door, and there was placed there an image of the Virgin Mary, who is worshipped in Catholic countries as divine. The prisoner was invited to kiss this image as he passed by, just as he began to descend the stair. Thus the very last moment of his life would be spent in performing an act of devotion, and thus, as they supposed, his soul would be saved. What a strange combination is this of superstition and tyranny!
After seeing all these things, the boys returned towards the entrance of the castle. They met several parties of ladies and gentlemen coming in; and just as they got to the door again, the carriage containing Mr. and Mrs. Holiday drove up. So Rollo bade the teacher and all the boys good by, after accompanying them a few minutes, as they walked along the road towards the place where they were to go. By this time his father and mother had descended from their carriage, and were ready to go in. So Rollo joined them, and went through the castle again, and saw all the places a second time.
When they came out, and were getting into the carriage, Mr. Holiday said that it was a very interesting place.
"Yes," said Mrs. Holiday; "and we have seen all that Byron speaks of in his poem, except the little island. Where is the little island?"
Mr. Holiday pointed out over the water of the lake, where a group of three tall trees seemed to be growing directly out of the water, only that there was a little wall around them below. They looked like three flowers growing in a flower pot set in the water.
"Yes," said Mrs. Holiday, "that must certainly be it. It corresponds exactly." So she repeated the following lines from Byron's poem, which describes the island in the language of one of the prisoners, who saw it from his dungeon window,
"And then there was a little isle,
Which in my very face did smile—
The only one in view;
A small green isle, it seemed no more,
Scarce broader than my dungeon floor;
But in it there were three tall trees,
And o'er it blew the mountain breeze,
And by it there were waters flowing,
And on it there were young flowers growing,
Of gentle breath and hue."
