M. Delabarbe de l'Empereur was a strong and active man, but he began to perceive that the lady was too much for him. He was already melting away with his exertions, while his partner was as cool as a cucumber. She, with her active young legs, her lightly filled veins, and small agile frame, could have gone on almost for ever; but M. de l'Empereur was more encumbered. Gallantry was at last beat by nature, his overtasked muscles would do no more for him, and he was fain to stop, dropping his partner into a chair, and throwing himself in a state of utter exhaustion against the wall. Katie was hardly out of breath as she received the congratulations of her friends; but at the moment she could not understand why they were quizzing her. In after times, however, she was often reproached with having danced a Frenchman to death in the evening, in revenge for his having bored her in the morning. It was observed that M. Delabarbe de l'Empereur danced no more that evening. Indeed, he very soon left the house. Katie had not been able to see Miss Golightly's performance, but it had been well worth seeing. She was certainly no ordinary performer, and if she did not quite come up to the remarkable movements which one sees on the stage under the name of dancing, the fault was neither in her will nor her ability, but only in her education. Charley also was peculiarly well suited to give her 'ample verge and room enough' to show off all her perfections. Her most peculiar merit consisted, perhaps, in her power of stopping herself suddenly, while going on at the rate of a hunt one way, and without any pause or apparent difficulty going just as fast the other way. This was done by a jerk which must, one would be inclined to think, have dislocated all her bones and entirely upset her internal arrangements. But no; it was done without injury, or any disagreeable result either to her brain or elsewhere. We all know how a steamer is manoeuvred when she has to change her course, how we stop her and ease her and back her; but Miss Golightly stopped and eased and backed all at once, and that without collision with any other craft. It was truly very wonderful, and Katie ought to have looked at her.
