Baron Bielfeld gives the following account of the ordinary employments, and the tone of conversation of the prince: “All the employments and all the pleasures of the prince are those of a man of understanding. He is, at this time, actually engaged in refuting the dangerous political reveries of Machiavel. His conversation at table is charming. He talks much and excellently well. His mind seems to be equal to all sorts of subjects, and his imagination produces on each of them a number of new and just ideas. His genius resembles the fire of the vestals that was never extinct. A decent and polite contradiction is not disagreeable to him. He possesses the rare talent of displaying the wit of others, and of giving them opportunity to shine on those subjects in which they excel. He jests frequently, and sometimes rallies, but never with asperity; and an ingenious retort does not displease him. “Nothing can be more elegant than this prince’s library. It has a view of the lake and gardens. A collection, not very numerous, but well chosen, of the best books in the French language are ranged in glass cases, which are ornamented with carvings and gildings in excellent taste. The portrait of M. De Voltaire occupies an honorable place in this library. He is the favorite author of the prince, who has, in general, a high esteem for good French writers both in prose and verse. “The evenings are devoted to music. The prince has a concert in his saloon, where no one enters who is not invited, and such invitation is regarded as an extraordinary favor. The prince has commonly performed a sonata and a concert for the flute, on which he plays in the greatest perfection. He fills the flute admirably well, has great agility with the fingers, and a vast fund of music. He composes himself sonatas. I have had the honor of standing behind him more than once while he was playing, and was charmed with his taste, especially in the _adagio_. He has a continual creation of new ideas.” CHAPTER IX.
