"This place honestly can't spare you for ten minutes, Pat," her brother said. "Well, honestly," she was beginning seriously, when she saw he was laughing at her, and broke off, with a shamefaced, laughing look for Paul. Then she announced that she was going down to the power-house, and, packing her thin white skirts about her, she started off, and they followed. Paul was not accustomed to seeing a lady in the power-house, and thought that her enthusiasm was rather nice to watch. She flitted about the great barnlike structure like a contented child, insisted upon displaying the trim stock-room to Paul, demanded a demonstration of the switchboard, spread her pretty hands over the whirling water that showed under the glass of the water-wheels, and hung, fascinated, over the governors. "I never get used to it," said Patricia, above the steady roaring of the river. "Do you realize that you are in one of the greatest force factories of the world? Look at it!" She swept with a gesture the monster machinery that shone and glittered all about them. "Do you realize that people miles and miles away are reading by lights and taking street-cars that are moved by this? Don't talk to me about the subway and the Pennsylvania Terminal!" "Oh, come, now!" said Paul. "Well!" she flared. "Do you suppose that anything bigger was ever done in this world than getting these things--these generators and water-wheels and the corrugated iron for the roof, and the door-knobs and tiles and standards and switchboard, and everything else, up to the top of the ridge from Emville and down this side of the ridge? I see that never occurred to you! Why, you don't KNOW what it was. Struggle, struggle, struggle, day after day--ropes breaking, and tackle breaking, and roads giving way, and rain coming! Suppose one of these had slipped off the trail--well, it would have stayed where it fell. But wait--wait!" she said, interrupting herself with her delightful smile. "You'll love it as we do one of these days!" "Not," said Paul to himself, as they started back to the house.
