So she danced, and talked far more than was her wont, surpassing herself in every way, and no more interested in poor Hexam than in twenty others. He took her in to supper, however, and after three hours of dancing she was glad to rest and be sheltered by his determined bulk, planted squarely before her corner. She knew that she had a coronet very close to her footstool, and that this brilliant night might be but the prologue to a lifetime of the only society in the world worth while, but she was not conscious of any desire beyond the brimming cup of the moment. Moreover, she had never so thoroughly enjoyed being a girl, and love-making would have bored her grievously. The duke claimed her, and after a desultory tour of the great reception-rooms and an infinite number of little cabinets, containing some of the most valuable of the Japanese and Indian treasures, he led her to the library, a luxurious room conducive to rapid friendship. With that amiable desire, peculiar to the kindly Englishman, to gratify the ingenuous curiosity of the American, he produced a huge leather volume containing the various patents of nobility that marked the upward evolution of his house from a barony in some remote period of the world's history to the present dukedom, and the royal letters that had accompanied them. It was something he never would have dreamed of doing for a stranger of his own country, or of any state in Europe, but the English humor Americans that please them much as they would engaging children; and Isabel's eyes sparkled with so lively an intelligence that the duke fancied she had literary intentions and might one day find such information useful. He even showed her his complicated coat-of-arms, which included a bend sinister, for he had royal blood in his veins; and this slanting rod interested Isabel as deeply as the moat under the window. She was even more interested in the duke's attitude; it was evident that he felt no more vanity in his royal descent than deprecation of its irregular cause and enduring emblem. It was, and that was the end of it; but he had quite enough imagination to appreciate the effect of so picturesque an incident in family history upon the mind of the young republican. "The best we can do is to descend irrelevantly from Washington, Hamilton, or Jefferson," said Isabel. "Only we have not yet reached the stage where we dare to acknowledge it on our coat-of-arms. The illusions of the American youth must be preserved. Even the fact that one of our Presidents was a son of Aaron Burr is still to be read only in the great volume of unwritten history. My father was a sort of walking edition of that work."
