Now, we have it on the best authority--or what ought to be the best authority--that is to say, we have it from a multitude of lady-writers, that the prospect of going to a first ball is one of the great joys of a young girl's life. The present writer, at all events, is not bold enough to impeach such an array of witnesses, and will only state the simple fact that in the case of Nan Beresford this prospect filled her mind with nothing but terror and dismay. It was in all sincerity that she had besought Sir George to let her off; though she might as well have gone down on her knees to the Monument. He could not understand why a young girl of seventeen should be really reluctant to go to a dance--and a very pretty dance, too, for the rooms were to be decorated with flags. And when Nan told her mother and sisters that she would far rather not go to the ball, her mother fancied she was afraid that her dress, being hurriedly made, would not compare well with her sisters' long studied costumes, while the sisters simply said to each other, 'Oh, she knows she can't dance.' There was some little truth in this last remark. Although she lived in a well-frequented house, where there were plenty of people coming and going, Nan had grown up very much apart. She had her own ways and occupations, which were mostly solitary. And dancing had never been a favourite amusement of hers. Of course, in the evening, when some young people were present, there was frequently a carpet-dance improvised; and then sometimes Nan was dragged in to make up a set at some square dance. She got through it mechanically; but it afforded her no special pleasure; and as for round dances, she said they made her giddy, and so she got excused. Giddy she said; and yet she could walk, without the slightest sensation in the brain, along the extreme verge of those high chalk-cliffs, to watch the jackdaws, and hawks, and gulls at nest-building time, and she could swing for an hour in a trapeze, so long as the seat was comfortable and you gave her a book to read. Not that she at all played the part of Cinderella in the house. Her mother was exceedingly fond of her--partly, perhaps, because Nan alone took the trouble to humour all her mysterious nerve-miseries; while her sisters tolerated her, though they thought her unsocial. Even this dress, when it did appear--and a thousand times Nan had inwardly prayed that it might not be ready in time--was quite as pretty as theirs. It was very pretty indeed; but somehow, Nan, as she regarded herself in the big mirror, convinced herself that there was not enough of her to carry off a ball-dress. Her sisters had a certain 'presence' that a grand costume became. She thought she was too thin--that she looked more like a school-girl than ever; and she wished that she were not freckled. When, at last, she was in the carriage with the others--Mr. Thomas had gone in a hansom rather than ride with the coachman--she said, cunningly,
