In this survey of the papers of Louis XV. by his grandson some very curious particulars relative to his private treasury were found. Shares in various financial companies afforded him a revenue, and had in course of time produced him a capital of some amount, which he applied to his secret expenses. The King collected his vouchers of title to these shares, and made a present of them to M. Thierry de Ville d'Avray, his chief valet de chambre. The Queen was desirous to secure the comfort of Mesdames, the daughters of Louis XV., who were held in the highest respect. About this period she contributed to furnish them with a revenue sufficient to provide them an easy, pleasant existence: The King gave them the Chateau of Bellevue; and added to the produce of it, which was given up to them, the expenses of their table and equipage, and payment of all the charges of their household, the number of which was even increased. During the lifetime of Louis XV., who was a very selfish prince, his daughters, although they had attained forty years of age, had no other place of residence than their apartments in the Chateau of Versailles; no other walks than such as they could take in the large park of that palace; and no other means of gratifying their taste for the cultivation of plants but by having boxes and vases, filled with them, in their balconies or their closets. They had, therefore, reason to be much pleased with the conduct of Marie Antoinette, who had the greatest influence in the King's kindness towards his aunts. Paris did not cease, during the first years of the reign, to give proofs of pleasure whenever the Queen appeared at any of the plays of the capital. At the representation of "Iphigenia in Aulis," the actor who sang the words, "Let us sing, let us celebrate our Queen!" which were repeated by the chorus, directed by a respectful movement the eyes of the whole assembly upon her Majesty. Reiterated cries of 'Bis'! and clapping of hands, were followed by such a burst of enthusiasm that many of the audience added their voices to those of the actors in order to celebrate, it might too truly be said, another Iphigenia. The Queen, deeply affected, covered her eyes with her handkerchief; and this proof of sensibility raised the public enthusiasm to a still higher pitch. The King gave Marie Antoinette Petit Trianon. [The Chateau of Petit Trianon, which was built for Louis XV., was not remarkably handsome as a building. The luxuriance of the hothouses rendered the place agreeable to that Prince. He spent a few days there several times in the year. It was when he was setting off from Versailles for Petit Trianon that he was struck in the side by the knife of Damiens, and it was there that he was attacked by the smallpox, of which he died on the 10th of May, 1774.--MADAME CAMPAN.]
