But he was gone now, so it was time for us to follow. I heard a big shout, and turned around—the city was dropping from under us like a shot! It made me sick all through, I was so scared. Jim turned gray and couldn’t say a word, and Tom didn’t say nothing, but looked excited. The city went on dropping down, and down, and down; but we didn’t seem to be doing nothing but just hang in the air and stand still. The houses got smaller and smaller, and the city pulled itself together, closer and closer, and the men and wagons got to looking like ants and bugs crawling around, and the streets like threads and cracks; and then it all kind of melted together, and there wasn’t any city any more it was only a big scar on the earth, and it seemed to me a body could see up the river and down the river about a thousand miles, though of course it wasn’t so much. By and by the earth was a ball—just a round ball, of a dull color, with shiny stripes wriggling and winding around over it, which was rivers. The Widder Douglas always told me the earth was round like a ball, but I never took any stock in a lot of them superstitions o’ hers, and of course I paid no attention to that one, because I could see myself that the world was the shape of a plate, and flat. I used to go up on the hill, and take a look around and prove it for myself, because I reckon the best way to get a sure thing on a fact is to go and examine for yourself, and not take anybody’s say-so. But I had to give in now that the widder was right. That is, she was right as to the rest of the world, but she warn’t right about the part our village is in; that part is the shape of a plate, and flat, I take my oath! The professor had been quiet all this time, as if he was asleep; but he broke loose now, and he was mighty bitter. He says something like this: “Idiots! They said it wouldn’t go; and they wanted to examine it, and spy around and get the secret of it out of me. But I beat them. Nobody knows the secret but me. Nobody knows what makes it move but me; and it’s a new power—a new power, and a thousand times the strongest in the earth! Steam’s foolishness to it! They said I couldn’t go to Europe. To Europe! Why, there’s power aboard to last five years, and feed for three months. They are fools! What do they know about it? Yes, and they said my air-ship was flimsy. Why, she’s good for fifty years! I can sail the skies all my life if I want to, and steer where I please, though they laughed at that, and said I couldn’t. Couldn’t steer! Come here, boy; we’ll see. You press these buttons as I tell you.”
