A week went by, and although the hurt to her foot had healed, like some flower in the dark Miriam drooped and languished in those gloomy vaults. Twice she prayed her uncle to be allowed to creep to the mouth of the hole behind the ridge of rock, there to breathe the fresh air and see the blessed sky. But this he would not suffer. The thing was too dangerous, he said; for although none knew the secret of their hiding-place, already two or three fugitives had found their way into the quarries by other entrances, and these it was very difficult to pass unseen.
"So be it," answered Miriam, and crept back to her cell.
Nehushta looked after her anxiously, then said: "If she cannot have air I think that she will soon die. Is there no way?"
"One," answered Ithiel, "but I fear to take it. The staircase from the spring leads to an ancient tower that, I am told, once was a palace of the kings, but now for these many years has been deserted, for its entrance is bricked up lest thieves should make it their home. None can come into that tower, nor is it used for purposes of war, not standing upon any wall, and there she might sit at peace and see the sun; yet I fear to let her do so."
"It must be risked," answered Nehushta. "Take me to visit this place."
So Ithiel led her to the cistern, and from the cistern up a flight of steps to a little vaulted chamber, into which they entered through a stone trap-door, made of the same substance as the paving of the chamber, so that, when it was closed, none would guess that there was a passage beneath. From this old store-room, for such it doubtless was, ran more steps, ending, to all appearance, in a blank wall. Coming to it, Ithiel thrust a piece of flat iron, a foot or more in length, into a crack in this wall, lifted some stone latch within, and pushed, whereon a block of masonry of something more than the height and width of a man, and quite a yard in thickness, swung outwards. Nehushta passed through the aperture, followed by Ithiel.
"See," he said, loosing his hold of the stone, which without noise instantly closed, so that behind them there appeared to be nothing but a wall, "it is well hung, is it not? and to come hither without this iron would be dangerous. Here is the crack where it must be set to lift the latch within."
"Whoever lived here guarded their food and water well," answered Nehushta.
