“There’s another trouble about theories: there’s always a hole in them somewheres, sure, if you look close enough. It’s just so with this one of Jim’s. Look what billions and billions of stars there is. How does it come that there was just exactly enough star-stuff, and none left over? How does it come there ain’t no sand-pile up there?” But Jim was fixed for him and says: “What’s de Milky Way?—dat’s what I want to know. What’s de Milky Way? Answer me dat!” In my opinion it was just a sockdologer. It’s only an opinion, it’s only _my_ opinion and others may think different; but I said it then and I stand to it now—it was a sockdologer. And moreover, besides, it landed Tom Sawyer. He couldn’t say a word. He had that stunned look of a person that’s been shot in the back with a kag of nails. All he said was, as for people like me and Jim, he’d just as soon have intellectual intercourse with a catfish. But anybody can say that—and I notice they always do, when somebody has fetched them a lifter. Tom Sawyer was tired of that end of the subject. So we got back to talking about the size of the Desert again, and the more we compared it with this and that and t’other thing, the more nobler and bigger and grander it got to look right along. And so, hunting among the figgers, Tom found, by and by, that it was just the same size as the Empire of China. Then he showed us the spread the Empire of China made on the map, and the room she took up in the world. Well, it was wonderful to think of, and I says: “Why, I’ve heard talk about this Desert plenty of times, but I never knowed before how important she was.” Then Tom says: “Important! Sahara important! That’s just the way with some people. If a thing’s big, it’s important. That’s all the sense they’ve got. All they can see is _size_. Why, look at England. It’s the most important country in the world; and yet you could put it in China’s vest-pocket; and not only that, but you’d have the dickens’s own time to find it again the next time you wanted it. And look at Russia. It spreads all around and everywhere, and yet ain’t no more important in this world than Rhode Island is, and hasn’t got half as much in it that’s worth saving.” Away off now we see a little hill, a-standing up just on the edge of the world. Tom broke off his talk, and reached for a glass very much excited, and took a look, and says: “That’s it—it’s the one I’ve been looking for, sure. If I’m right, it’s the one the dervish took the man into and showed him all the treasures.” So we begun to gaze, and he begun to tell about it out of the Arabian Nights. CHAPTER X. THE TREASURE-HILL Tom said it happened like this.
