"It is well," Archie said, "for if in the end we have to leave the castle, you, who have proved yourself so strong and brave, can, if needs be, take to the hills with me; but she could not support the fatigues of such a life. And now, dear, we have marched all night and shall be glad of food; while it is preparing I will to the walls and see what is going on."

As Archie reached the battlement a loud cheer broke from the defenders gathered there, and Sandy Grahame hurried up to him.

"Welcome back, Sir Archie; glad am I to give up the responsibility of this post, although, indeed, it is not I who have been in command, but Lady Marjory. She has been always on the walls, cheering the men with her words and urging them to deeds of bravery; and, indeed, she has frightened me sorely by the way in which she exposed herself where the arrows were flying most thickly, for as I told her over and over again, if the castle were taken I knew that you would be sure that I had done my best, but what excuse should I be able to make to you if I had to bear you the news that she had been killed?"

"And what did she say to that, Sandy?"

"Truth, Sir Archie, she's a woman and wilful, and she just laughed and said that you would know you could not keep her in order yourself, and could not therefore expect me to rule her."

"That is so, Sandy," Archie laughed; "but now that I am back I will for once exert my authority, and will see that she runs into no further danger. And now, how goes the siege?"

"So far they have done but little damage, Sir Archie; but the machines which they brought up yesterday will, I fear, play havock with our walls. They have not yet begun their work, for when they brought them up yesterday afternoon our men shot so hotly that they had to fall back again; but in the night they have thrown up high banks of earth, and have planted the engines under their shelter, and will, ere long, begin to send their messengers against our walls. Thrice they assaulted the works beyond the drawbridge and twice we beat them back; but last night they came on with all their force. I was myself there, and after fighting for a while and seeing they were too strong for us, I thought it best to withdraw before they gained footing in the work, and so had time to draw off the men and raise the drawbridge."

"Quite right, Sandy! The defenders of the post would only have been slaughtered, and the assailants might have rushed across the drawbridge before it could have been raised. The post is of little importance save to defend the castle against a sudden surprise, and would only have been a source of constant anxiety and loss. How many do you reckon them? Judging by their tents there must be three or four thousand."

"About three thousand, Sir Archie, I make it; and as we had no time to get the tenants in from my lady's Ayrshire estate, we have but two hundred men in the castle, and many of these are scarce more than boys."

"I have brought a hundred and fifty with me, Sandy, so we have as many as we can use on the walls, though I could wish I had another hundred or two for sorties."
