To confirm what I have now said, and further to show the miserable effects of a confined education, I shall here insert a passage, which will hardly obtain belief. In hopes to ingratiate myself further into his majesty's favour, I told him of "an invention, discovered between three and four hundred years ago, to make a certain powder, into a heap of which, the smallest spark of fire falling, would kindle the whole in a moment, although it were as big as a mountain, and make it all fly up in the air together, with a noise and agitation greater than thunder. That a proper quantity of this powder rammed into a hollow tube of brass or iron, according to its bigness, would drive a ball of iron or lead, with such violence and speed, as nothing was able to sustain its force. That the largest balls thus discharged, would not only destroy whole ranks of an army at once, but batter the strongest walls to the ground, sink down ships, with a thousand men in each, to the bottom of the sea, and when linked together by a chain, would cut through masts and rigging, divide hundreds of bodies in the middle, and lay all waste before them. That we often put this powder into large hollow balls of iron, and discharged them by an engine into some city we were besieging, which would rip up the pavements, tear the houses to pieces, burst and throw splinters on every side, dashing out the brains of all who came near. That I knew the ingredients very well, which were cheap and common; I understood the manner of compounding them, and could direct his workmen how to make those tubes, of a size proportionable to all other things in his majesty's kingdom, and the largest need not be above a hundred feet long; twenty or thirty of which tubes, charged with the proper quantity of powder and balls, would batter down the walls of the strongest town in his dominions in a few hours, or destroy the whole metropolis, if ever it should pretend to dispute his absolute commands." This I humbly offered to his majesty, as a small tribute of acknowledgment, in turn for so many marks that I had received, of his royal favour and protection.
