It was somewhere towards the end of February, when one fine day a mighty sound of hammering arose from the midst of their camp.

"What are they doing now, think ye, Walter?" asked my lady lightly. "Is it possible that they look for so long a siege that they are beginning to build houses for themselves? Truly they are wise, for if my Lord of Salisbury means to stay there until I open my gates to him, he will grow weary of braving these harsh East winds in no better shelter than a tent."

But for once Walter Brand had no answering smile to give her.

"I fear me 'tis a sow that they are making," he said, "and if that be so we had need to look to our arms."

"A sow," repeated the Countess in graver tones. "I have oft heard of such machines, but I never saw one. Thy words hint of danger, Walter. Is a sow then so deadly that our walls cannot resist its onslaught?"

"It is deadly because it brings the enemy nearer us, my lady," answered Walter. "Hitherto our walls have been our shelter; without them we could not stand a moment, for we are outnumbered by the English a score of times over. These sows, as men name them, are great wooden buildings, which can hold at least forty men inside, and with a platform above where other thirty can stand. They be mounted on two great wheels, and can be run close up to the walls, and as they are oft as high as a house, 'twill be an easy matter for the men who stand on the platform to set up ladders and scale our walls, and after that what chance will there be for our poor handful of men? 'Tis not for myself I fear," he went on, "nor yet for the men. We are soldiers and we can face death; but if thou wouldst not fall into the hands of this English Earl, my lady, I would advise that thou, and Marian, and little Mistress Marjory and Mistress Jean, should set out in the boat the first dark night, when it is calm. 'Tis but ten miles to the Bass, and thou couldst aye find shelter there."

Thus spake honest Walter, who was, as I have said, ever timorous where my lady was concerned; but at his words she shook her head.

"And leave the Castle, Walter?" she said. "That will I never do till I open its doors to my own true lord. As for this English Earl and his sows—tush! I care not for them. If they have wood we have rock, my lad, and I warrant 'twill be a right strong sow that will stand upright after a lump of Dunbar rock comes crashing down on its back; so keep up thy courage, and get out the picks and crowbars. If they build sows by day, we can quarry stones by night."

So saying, my lady shook her little white fist, by way of defiance, in the direction of the tents which studded the greensward opposite, while Walter went off to do her bidding, muttering to himself that the famous Randolph himself was not better than she, for she had been born with the courage of Bruce, and the wisdom of Solomon.

So it came about, that, while the English gave over wasting arrows for a time, and turned their attention to the building of two great clumsy wooden structures, we would steal down in a body on dark nights to the little postern that opened on the shore, when the waves were dashing against the rocks, and making enough noise to deaden the sound of the picks, and while we women held a lanthorn or two, the men worked with might and main, hewing at the solid rock which stretched out to seaward for a few yards at the foot of the Castle wall. Then, when some huge block was loosened, ropes would be lowered, and with much ado, for our numbers were small, the unwieldy mass would be hoisted up, and placed in position on the top of the Castle, hidden, it is true, behind the battlements, but with the stones in front of it displaced, so that it could be rolled over with ease at a given signal.
