“You ever seen a picture of the volcano in Hawaii, Anne?” he asked. And when she told him no, he added almost eagerly: “It looks just like this, only very much more wonderful.” And then to the admiring and thrilled little girl he described the crater of the great volcano of Mauna Loa as he had read of it. “It’s—it’s wonderful to know all those things,” said Anne when he paused a moment. “Some day I’m going to see them all, too,” he answered. “Some day I’m going everywhere in the world and see myself all the things in the books—some day when I’m rich—when I’ve done something.” Then, as his problem came back to him with the words, he relapsed into silence, sitting with his arm about the girl’s shoulders and staring idly at the little stream of smoke coming up from the ground before him. For a long time he sat silent. The familiar scene around, which he had always accepted as usual and without interest, suddenly seemed remarkable and inspiring. He thought of these vast fires in the ground beneath his feet, burning away the coal year after year, and discharging their heat upward into the air uselessly. This tremendous waste seemed now suddenly appalling. He withdrew his arm from around Anne’s shoulder, and, leaning forward, put his hand down close to the little crevice. It was hot there—hot enough to boil water in a kettle, perhaps, he thought. A picture he had seen once, in a book, of James Watt discovering the power of steam, came to his mind. He sat up again and turned to the girl. “You ever heard of James Watt, Anne?” Anne shook her head. “He was the man who discovered about steam. He was just a boy, Anne. One day he was sitting beside his mother’s hearth looking at a big iron kettle that had water boiling in it. And he could see that the steam was lifting up the lid of the kettle. And then all at once it came to him how powerful the steam must be, and why couldn’t he do something with it. “You see, Anne, nobody had ever thought of that before. It looks easy enough to us—that you can make steam and use the power—but nobody had ever thought of it then. And it was right in front of their eyes all the time, and they couldn’t see it. But James Watt saw it. And when he got the idea he wouldn’t give it up, no matter what anybody said. He worked and worked, and finally he built an engine that would use the power that steam has. “That was the first steam-engine, Anne. Just think of it—the first steam-engine. And James Watt doped it out all by himself—just because he had noticed how the steam lifted the lid of that kettle. And he had seen it do that hundreds of times before—and so had everybody else—and never thought anything about it. Isn’t that wonderful, Anne?” The girl’s eyes were very big and tender as she looked up into his face. “Yes—it’s very wonderful, Jimmy. You know about so many wonderful things,” she said softly.
