Madame Defarge cast down her eyes, and reflected a little.

“The child also,” observed Jacques Three, with a meditative enjoyment of his words, “has golden hair and blue eyes. And we seldom have a child there. It is a pretty sight!”

“In a word,” said Madame Defarge, coming out of her short abstraction, “I cannot trust my husband in this matter. Not only do I feel, since last night, that I dare not confide to him the details of my projects; but also I feel that if I delay, there is danger of his giving warning, and then they might escape.”

“That must never be,” croaked Jacques Three; “no one must escape. We have not half enough as it is. We ought to have six score a day.”

“In a word,” Madame Defarge went on, “my husband has not my reason for pursuing this family to annihilation, and I have not his reason for regarding this Doctor with any sensibility. I must act for myself, therefore. Come hither, little citizen.”

The wood–sawyer, who held her in the respect, and himself in the submission, of mortal fear, advanced with his hand to his red cap.

“Touching those signals, little citizen,” said Madame Defarge, sternly, “that she made made to the prisoners; you are ready to bear witness to them this very day?”

“Ay, ay, why not!” cried the sawyer. “Every day, in all weathers, from two to four, always signalling, sometimes with the little one, sometimes without. I know what I know. I have seen with my eyes.”

He made all manner of gestures while he spoke, as if in incidental imitation of some few of the great diversity of signals that he had never seen.

“Clearly plots,” said Jacques Three. “Transparently!”

“There is no doubt of the Jury?” inquired Madame Defarge, letting her eyes turn to him with a gloomy smile.

“Rely upon the patriotic Jury, dear citizeness. I answer for my fellow–Jurymen.”

“Now, let me see,” said Madame Defarge, pondering again. “Yet once more! Can I spare this Doctor to my husband? I have no feeling either way. Can I spare him?”

“He would count as one head,” observed Jacques Three, in a low voice. “We really have not heads enough; it would be a pity, I think.”

“He was signalling with her when I saw her,” argued Madame Defarge; “I cannot speak of one without the other; and I must not be silent, and trust the case wholly to him, this little citizen here. For, I am not a bad witness.”

The Vengeance and Jacques Three vied with each other in their fervent protestations that she was the most admirable and marvellous of witnesses. The little citizen, not to be outdone, declared her to be a celestial witness.

“He must take his chance,” said Madame Defarge. “No, I cannot spare him! You are engaged at three o’clock; you are going to see the batch of to–day executed.—You?”

Adam’s comment pleased the old gentleman.

“I have it in my bones, sir, that you have struck—or rather reasoned out—a great truth.”

Sir Nathaniel went on cheerfully. “When the world of commerce wakes up to the value of your find, it will be as well that your title to ownership has been perfectly secured. If anyone ever deserved such a gain, it is you.”

With his friend’s aid, Adam secured the property without loss of time. Then he went to see his uncle, and told him about it. Mr. Salton was delighted to find his young relative already constructively the owner of so fine an estate—one which gave him an important status in the county. He made many anxious enquiries about Mimi, and the doings of the White Worm, but Adam re-assured him.

The next morning, when Adam went to his host in the smoking-room, Sir Nathaniel asked him how he purposed to proceed with regard to keeping his vow.

“It is a difficult matter which you have undertaken. To destroy such a monster is something like one of the labours of Hercules, in that not only its size and weight and power of using them in little-known ways are against you, but the occult side is alone an unsurpassable difficulty. The Worm is already master of all the elements except fire—and I do not see how fire can be used for the attack. It has only to sink into the earth in its usual way, and you could not overtake it if you had the resources of the biggest coal-mine in existence. But I daresay you have mapped out some plan in your mind,” he added courteously.

“I have, sir. But, of course, it may not stand the test of practice.”

“May I know the idea?”

“Well, sir, this was my argument: At the time of the Chartist trouble, an idea spread amongst financial circles that an attack was going to be made on the Bank of England. Accordingly, the directors of that institution consulted many persons who were supposed to know what steps should be taken, and it was finally decided that the best protection against fire—which is what was feared—was not water but sand. To carry the scheme into practice great store of fine sea-sand—the kind that blows about and is used to fill hour-glasses— was provided throughout the building, especially at the points liable to attack, from which it could be brought into use.

“I propose to provide at Diana’s Grove, as soon as it comes into my possession, an enormous amount of such sand, and shall take an early occasion of pouring it into the well-hole, which it will in time choke. Thus Lady Arabella, in her guise of the White Worm, will find herself cut off from her refuge. The hole is a narrow one, and is some hundreds of feet deep. The weight of the sand this can contain would not in itself be sufficient to obstruct; but the friction of such a body working up against it would be tremendous.”

“One moment. What use would the sand be for destruction?”

“None, directly; but it would hold the struggling body in place till the rest of my scheme came into practice.”
