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."
"And what is the rest?"
"As the sand is being poured into the well-hole, quantities of dynamite can also be thrown in!"
"Good. But how would the dynamite explode--for, of course, that is what you intend. Would not some sort of wire or fuse he required for each parcel of dynamite?"
Adam smiled.
"Not in these days, sir. That was proved in New York. A thousand pounds of dynamite, in sealed canisters, was placed about some workings. At the last a charge of gunpowder was fired, and the concussion exploded the dynamite. It was most successful. Those who were non-experts in high explosives expected that every pane of glass in New York would be shattered. But, in reality, the explosive did no harm outside the area intended, although sixteen acres of rock had been mined and only the supporting walls and pillars had been left intact. The whole of the rocks were shattered."
Sir Nathaniel nodded approval.
"That seems a good plan--a very excellent one. But if it has to tear down so many feet of precipice, it may wreck the whole neighbourhood."
"And free it for ever from a monster," added Adam, as he left the room to find his wife.
Chapter 25 - The Last Battle
Lady Arabella had instructed her solicitors to hurry on with the conveyance of Diana's Grove, so no time was lost in letting Adam Salton have formal possession of the estate. After his interview with Sir Nathaniel, he had taken steps to begin putting his plan into action. In order to accumulate the necessary amount of fine sea-sand, he ordered the steward to prepare for an elaborate system of top-dressing all the grounds. A great heap of the sand, brought from bays on the Welsh coast, began to grow at the back of the Grove. No one seemed to suspect that it was there for any purpose other than what had been given out.
