As the window of her room looked upon the terrace, and was only five feet from the ground, she let herself down by a cord, taking care to choose the days when there was a post, Mlle. de Mars was busy writing to her friends, and her mother out of the way. Leaning upon the low wall of the terrace she instructed the little boys who stood below in what she happened to know herself, i.e., the catechism, the beginning of the principles of music, and certain tragedies which she and they declaimed, and as these instructions were mingled with cakes, fruit, and toys which she threw over the wall to them, they were very well attended, until Mlle. de Mars one day surprised them, and laughed so heartily at the verses recited in patois by the little boys that the class came to an end.

From her earliest childhood Félicité had shown a remarkable talent for music and acting, of which her mother was so proud that she did her best to spoil the child by bringing her forward on every occasion to display her talents. She learned to sing, to play the harp, to recite verses; she was dressed up as an Amour or a Hebe, she acted Iphigenia and Hector and Zaire, and the constant flattery and notice she received evidently and naturally turned her head and laid the foundation of that vanity and self-satisfaction which appears so conspicuously in the records of her life.

When she was about twelve years old she left Burgundy with her mother and Mlle. de Mars. They travelled partly by boat on the Loire, partly with their own carriage and horses, to Paris, where they established themselves, and where Félicité pursued her musical studies with increased ardour. She must have been a precocious young person, for when she was eleven years old the son of the neighbouring doctor fell in love with her, managed to give her a note, which she showed to Mlle. Mars, and meeting with indignant discouragement, he ran away for three years, after which he came home and married somebody else.

M. de Saint-Aubin, meanwhile, whose affairs, which grew worse and worse, were probably not improved by his mismanagement nor by the residence of his wife and daughter in Paris, stayed in Burgundy, coming every now and then to see them. Mlle. de Mars had left them, to the great grief of Félicité, who was now fourteen, and whom the Baron de Zurlauben, Colonel of the Swiss Guards, was most anxious to marry; but, as he was eighty years old, she declined his offer, and also another of a young widower who was only six-and-twenty, extremely handsome and agreeable, and had a large fortune.

By this time, however, she had made up her mind to marry an homme de qualité, who belonged to the court. What she then wished was to marry a certain M. de la Popelinière, whom she thought combined the advantages she desired, though he was nothing more illustrious than a fermier général, besides being an old man. However, her admiration was not sufficiently returned for him to be of the same opinion.

Since the departure of Mlle. de Mars the vanity and thirst for admiration fostered by her mother’s foolish education had greatly increased, but between Mme. de Saint-Aubin and her daughter, though there was affection, there was neither ease nor confidence; the young girl was afraid of her mother, but adored her father. The society into which she was thrown formed her character at an early age, and the artificial, partly affected, partly priggish tone which is apparent in all her voluminous writings detracted from the charm of her undoubtedly brilliant talents.

She already played the harp so remarkably as to excite general admiration, and amongst those who were anxious to be introduced to and to hear her was the philosopher d’Alembert.

Félicité was very much flattered when she heard this, and very much disgusted when she saw him, for he was ugly, common-looking, had a shrill voice, and told stories that displeased her.

D’Alembert was one of the most constant and intimate habitués of the salon of Mme. Geoffrin, then the stronghold of the philosophers and encyclopædists, as that of the Duchesse de Luxembourg was of the aristocratic beau monde.
