Mark Twain: A Connecticut Yankee in King Arthur's Court

THE TALE OF THE LOST LAND CHAPTER 7: MERLIN'S TOWER (continued)

I took Clarence into my confidence, to a certain degree, and we went to work privately. I told him that this was a sort of miracle that required a trifle of preparation, and that it would be sudden death to ever talk about these preparations to anybody. That made his mouth safe enough. Clandestinely we made a few bushels of first-rate blasting powder, and I superintended my armorers while they constructed a lightning-rod and some wires. This old stone tower was very massive--and rather ruinous, too, for it was Roman, and four hundred years old. Yes, and handsome, after a rude fashion, and clothed with ivy from base to summit, as with a shirt of scale mail. It stood on a lonely eminence, in good view from the castle, and about half a mile away.

Working by night, we stowed the powder in the tower--dug stones out, on the inside, and buried the powder in the walls themselves, which were fifteen feet thick at the base. We put in a peck at a time, in a dozen places. We could have blown up the Tower of London with these charges. When the thirteenth night was come we put up our lightning-rod, bedded it in one of the batches of powder, and ran wires from it to the other batches. Everybody had shunned that locality from the day of my proclamation, but on the morning of the fourteenth I thought best to warn the people, through the heralds, to keep clear away--a quarter of a mile away. Then added, by command, that at some time during the twenty-four hours I would consummate the miracle, but would first give a brief notice; by flags on the castle towers if in the daytime, by torch-baskets in the same places if at night.

Thunder-showers had been tolerably frequent of late, and I was not much afraid of a failure; still, I shouldn't have cared for a delay of a day or two; I should have explained that I was busy with affairs of state yet, and the people must wait.
