“The desperadoes paled visibly as I spoke, and after making due apologies for interfering with the train, fled shrieking from the car. They had heard of me before.

“‘I thank you, sir,’ began the Emperor, as the would-be assassins fled, but I cut him short. ‘They must not be allowed to escape,’ I said, and with that I started in pursuit of the desperate fellows, overtook them, and glued them with the gum they had prepared for our detention to the face of a precipice that rose abruptly from the side of the railway, one hundred and ten feet above the level. There I left them. We melted the glue from the tracks by means of our steam heating apparatus, and were soon booming merrily on our way to Rio Janeiro when I was fêted and dined continuously for weeks by the people, though strange to say the Emperor’s behaviour toward me was very cool.”

“And did the robbers ever get down?” asked the Twins.

“Yes, but not in a way they liked,” Mr. Munchausen replied. “The sun came out, and after a week or two melted the glue that held them to the precipice, whereupon they fell to its base and were shattered into pieces so small there wasn’t an atom of them to be found when a month later I passed that way again on my return trip.”

“And didn’t the Emperor treat you well, Uncle Munch?” asked the Imps.

“No—as I told you he was very cool towards me, and I couldn’t understand it, then, but I do now,” said the Baron. “You see he was very much in need of ready cash, the Emperor was, and as the taxpayers were already growling about the expenses of the Government he didn’t dare raise the money by means of a tax. So he arranged with the desperadoes to stop the train, capture him, and hold him for ransom. Then when the ransom came along he was going to divide up with them. My sudden appearance, coupled with my determination to rescue him, spoiled his plan, you see, and so he naturally wasn’t very grateful. Poor fellow, I was very sorry for it afterward, because he really was an excellent ruler, and his plan of raising the money he needed wasn’t a bit less honest than most other ways rulers employ to obtain revenue for State purposes.”

“Well, now, let’s get back to the runaway engine,” said the Twins. “You can tell us more about South America after you get through with that. How did the engine come to run away?”

“It was simple enough,” said the Baron. “The engineer, after starting the train came back into the smoking car to get a light for his pipe, and while he was there the coupling-pin between the engine and the train broke, and off skipped the engine twice as fast as it had been going before. The relief from the weight of the train set its pace to a mile a minute instead of a mile in two minutes, and there we were at a dead stop in front of the Vitriol Station with nothing to move us along. When the engineer saw what had happened he fainted dead away, because you know if a collision had occurred between the runaway engine and the train ahead he would have been held responsible.”

“Couldn’t the fireman stop the engine?” asked the Twins.

“No. That is, it wouldn’t be his place to do it, and these railway fellows are queer about that sort of thing,” said the Baron. “The engineers would go out upon a strike if the railroad were to permit a stoker to manage the engine, and besides that the stoker wouldn’t undertake to do it at a stoker’s wages, so there wasn’t any help to be looked for there. The conductor happened to be nearsighted, and so he didn’t find out that the engine was missing until he had wasted ten or twenty minutes examining the brakes, by which time, of course, the runaway was miles and miles up the track. Then the engineer came to, and began to wring his hands and moan in a way that was heart-rending. The conductor, too, began to cry, and all the brakemen left the train and took to the woods. They weren’t going to have any of the responsibility for the accident placed on their shoulders. Whether they will ever turn up again I don’t know. But I realised as soon as anybody else that something had to be done, so I rushed into the telegraph office and telegraphed to all the station masters between the Vitriol Reservoir and Cimmeria to clear the track of all trains, freight, local, or express, or somebody would be hurt, and that I myself would undertake to capture the runaway engine. This they all promised to do, whereupon I bade good-bye to my fellow-travellers, and set off up the track myself at full speed. In a minute I strode past Sulphur Springs, covering at least eight ties at a stretch. In two minutes I thundered past Lava Hurst, where I learned that the engine had twenty miles start of me. I made a rapid calculation mentally—I always was strong in mental arithmetic, which showed that unless I was tripped up or got side-tracked somewhere I might overtake the runaway before it reached Noxmere. Redoubling my efforts, my stride increased to twenty ties at a jump, and I made the next five miles in two minutes. It sounds impossible, but really it isn’t so. It is hard to run as fast as that at the start, but when you have got your start the impetus gathered in the first mile’s run sends you along faster in the second, and so your speed increases by its own force until finally you go like the wind. At Gasdale I had gained two miles on the engine, at Sneakskill I was only fifteen miles behind, and upon my arrival at Noxmere there was scarcely a mile between me and the fugitive. Unfortunately a large crowd had gathered at Noxmere to see me pass through, and some small boy had brought a dog along with him and the dog stood directly in my path. If I ran over the dog it would kill him and might trip me up. If I jumped with the impetus I had there was no telling where I would land. It was a hard point to decide either way, but I decided in favour of the jump, simply to save the dog’s life, for I love animals. I landed three miles up the road and ahead of the engine, though I didn’t know that until I had run ten miles farther on, leaving the engine a hundred yards behind me at every stride. It was at Miasmatica that I discovered my error and then I tried to stop. It was almost in vain; I dragged my feet over the ties, but could only slow down to a three-minute gait. Then I tried to turn around and slow up running backward; this brought my speed down ten minutes to the mile, which made it safe for me to run into a hay-stack at the side of the railroad just this side of Cimmeria.
