I found that it was usual for a man to be executed with great ceremony upon the spot whereon his crime had been committed. That in case of rebellions or tumults in the provinces, when large numbers were not unfrequently condemned to death, the sentence of the law was carried out in the chief towns of the disturbed districts. That large numbers of people were thus sometimes discharged from a single market-place, and that the repeated strokes appeared to shake, or crack, or pierce in some degree that portion of the sky towards which the artillery had been directed. I here at once saw that I had discovered the true cause of earthquakes and volcanoes; and this shows how great light may be thrown upon theories concerning the hidden constitution of this earth, by going more deeply into the matter of it than had been done by any one before I dug my hole. Our volcanoes, it is now proved, are situated over the market-places of various provincial towns in Skitzland. When a revolution happens, the rebels are shot up,—discharged from mortars by means of an explosive material evidently far more powerful than our gunpowder or gun-cotton; and they are pulverised by the friction in grinding their way through the earth. How simple and easy truth appears, when we have once arrived at it. The sound of muffled drums approached us, and a long procession turned the corner of a street. I was placed in the middle of it,—Baron Terroro by my side. All then began to float so rapidly away, that I was nearly left alone, when forty arms came back and collared me. It was considered to be a proof of my refractory disposition, that I would make no use of my innate power of flight. I was therefore dragged in this procession swiftly through the air, drums playing, fifes lamenting. We alighted on the spot where I had fallen, and the hole through which I had come I saw above me. It was very small, but the light from above shining more vividly through it made it look, with its rough edges, like a crumpled moon. A quantity of some explosive liquid was poured into a large mortar, which had been erected (under the eye of Baron Terroro) exactly where my misfortune happened. I was then thrust in, the Baron ramming me down, and pounding with a long stock or pestle upon my head in a noticeably vicious manner. The Baron then cried “Fire!” and as I shot out, in the midst of a blaze, I saw him looking upward. CHAPTER THE FIFTH. My revenge on the Skitzlanders.
