'Holy mother! what is the matter, child?' cried lady Margaret, of late easily fluttered. 'Is it my lord Herbert you mean, or my lord of Worcester?' 'My lord Herbert, my lady. I dread lest he should be gone ere I have found a time to tell him.' 'He rides again after dinner,' said lady Margaret. 'Then, dear my lady, if you would keep me from great doubt and disquiet, let me have the ear of my lord for a few moments.' Lady Margaret rang for her page, and sent him to find his master and request his presence in her parlour. Within five minutes lord Herbert was with them, and within five more, Dorothy had ended her tale of the night, uninterrupted save by lady Margaret's exclamations of sympathy. 'And now, my lord, what am I to do?' she asked in conclusion. Lord Herbert made no answer for a few moments, but walked up and down the room. Dorothy thought he looked angry as well as troubled. He burst at length into a laugh, however, and said merrily, 'I have it, ladies! I see how we may save my father much annoyance without concealment, for nothing must be concealed from him that in any way concerns the house. But the annoyance arising from any direct attempt at discovering the wrongdoers would be endless, and its failure almost certain. But now, as I would plan it, instead of trouble my father shall have laughter, and instead of annoyance such a jest as may make him good amends for the wrong done him by the breach of his household laws. Caspar has explained to you all concerning the water-works, I believe, cousin?' 'All, my lord. I may without presumption affirm that I can, so long as there arises no mishap, with my own hand govern them all. Caspar has for many weeks left everything to me, save indeed the lighting of the furnace-fire.' 'That is as I would have it, cousin. So soon then as it is dark this evening, you will together, you and Caspar, set the springs which lie under the first stone of the paving of the bridge. Thereafter, as you know, the first foot set upon it will drop the drawbridge to the stone bridge, and the same instant convert the two into an aqueduct, filled with a rushing torrent from the reservoir, which will sweep the intruders away. Before they shall have either gathered their discomfited wits or raised their prostrate bones, my father will be out upon them, nor shall they find shelter for their shame ere every soul in the castle has witnessed their disgrace.' 'I had thought of the plan, my lord; but I dreaded the punishment might be too severe, not knowing what the water might do upon them.'
