There was no well in Careg Cennen. It would not have availed to have sunk one. In the dry limestone there were no springs. Gerald the Norman would not have reared his castle on this barren head of rock had he not known that water was accessible in this natural cave.
But this cavern had been known and utilized long before the Norman adventurers burst into Wales. At some remote age, we know not how many centuries or tens of centuries before, some warfaring people had surrounded the top of the hill with a wall of stones, not set in mortar, but sustained in place by their own weight. And to supply themselves with water, they had cut a path like a thread in the face of the precipice to the mouth of a gaping cavern that could be seen only from the slopes of the Black Mountains, on the further side of the Cennen River.
In this vault water incessantly dripped, not in rapid showers, but slowly; in wet weather more rapidly than at times of dryness, yet even in the most burning, rainless seasons, there never was an absolute cessation of falling drops. To receive these, bowls had been scooped out in ledges of rock; and hither came the maidens daily with their pitchers, to supply the wants of all in the castle. What the Norman builders had done was to broaden the path by cutting deeper into the face of the cliff, and to build up the face towards the precipice, leaving loopholes at intervals, to prevent accidents such as might happen through vertigo, or a turn of an ankle, or a slip on the polished lime-rock. The whole mouth of the cavern had also been walled up, so that no one unacquainted with the arrangements within the castle would have suspected its existence.
To fill the pitchers the water-carriers were furnished with wooden spoons and shallow ladles, with which they scooped up the liquid from the rock-basins into their vessels.
Hither Nest, the wife of Gerald of Windsor, had brought Pabo. She had learned what was the doom of the Archpriest so soon as the interview was over between him, the bishop, and her husband. Nest was a subtle woman. Lovely beyond any other woman in Britain, and with that exquisite winsomeness of manner which only a Celtic woman possesses, which a Saxon can ape but not acquire, she was able when she exerted her powers to cajole Gerald, and obtain from him much that his judgment warned him he should not yield. For a long time she had induced him even to harbor her brother Griffith, but he did so only so long as the young man was not in open revolt against King Henry.
She had not on this occasion attempted to induce Gerald to mitigate the sentence on Pabo. She reserved her cajolery for another occasion. Now, she had recourse to other means. With a little cleverness, she had succeeded in securing the key of the dungeon; but for her own good reasons she did not desire that her husband should learn, or even suspect, that she had contrived the escape of the prisoner.
Now Pabo stood by her in the great natural domed vault in the bowels of the mountain, crowned by Careg Cennen Castle; and by the flicker of the lamp he saw her face, and wondered at its beauty.
"Pabo, priest of God!" she said, and her face worked with emotion. "Heaven alone knows what a life I lead—a double life, a life behind a mask. I have a poor, weak, trembling woman's heart, that bleeds and suffers for my people. I have but one love—one only love, that fills and flames in all my veins: it is the love of Wales, of my country, my beautiful, my sovereign country. And, O God! my people. Touch them, and I quiver and am tortured, and durst not cry out. Yet am I linked to one who is my husband, and I belong to him in body. Yet hath he not my immortal soul, he hath not this passionate heart. Nay! Not one single drop of the burning Welsh blood that dances and boils in every artery." She clasped her hands to her heart. "Oh, Pabo, my lot is in sad quarters! My life is one continuous martyrdom for my country, for my people, for their laws, their freedom, their Church! What can I do? Look at these women's fingers! What gifts have I? Only this fair face and this golden hair, and a little mother wit. I give all to the good cause. And now," she became more calm in tone, and she put forth her hand and clasped the priest by the wrist, and spake in measured tones, though her finger-ends worked nervously. "And now—learn this. For reasons that I cannot speak plainly, I would not have my husband know that I have contrived thy escape. And I cannot contrive to pass thee out through the gates. There is but one way that thou canst be freed. See—the women come hither to draw water, and the door creaks on its hinges whensoever opened. When thou hearest the door cry out, then hide thee under the stair, or yonder in the depth of the cave. None of the wenches penetrate further than these basins. But after they have left—and they come but in the morning and at eve—then thou hast this place to thyself. Know that there is no escape downwards from the eyelet-holes. It is a sheer fall—and if that were adventured, thou wouldst be dashed to pieces, as was one of the Normandy masons who was engaged on the wall. He lost his foothold and fell—and was but a mangled heap at the bottom. No—that way there is no escape. I have considered well, and this is what I have devised." She paused and drew a long breath. "There stands a stout and well-rooted thorn-tree on the crag above. I will tarry till supper-time, when my lord and his men will be merry over their cups, and then will I swing a bracelet—this." She took off a twisted serpent of gold, quaintly wrought, from her wrist. "This I will attach to a string, and I will fasten the other end to the thorn-tree. Then shall the bracelet be swung to and fro, and do thou remain at one of the loopholes, and put forth thine hand and catch the string as it swings. Hold it fast and draw it in. Then I will attach a knotted rope to the string, and do thou draw on until thou hast hold of the rope. Thereupon I will make the other end fast to the thorn-tree, and as thou canst not descend, mount, and thou art free."
Pabo hesitated—then said, "It seems to me that these eyelet-holes are too narrow for a man's body to pass through."
"It is well said," answered Nest, "and of that I have thought. Here is a stout dagger. Whilst thou canst, work out the mortar from between the joints of the masonry about the window-slit yonder. It is very fresh and not set hard. But remove not the stone till need be."
