We left Mr. Jackson's before nine—came home—changed our gowns, and went with Barrois to the Hameau de Chantilly, one of the many public gardens open most nights for dancing, &c. […] Nothing can be prettier than both the general effect and the details of this garden. Under the trees was an excellent orchestra, led by the same man (a creole) who conducted the music at M. Demidoff’s, and there were, I know not how many, sets of French country dances; we saw two danced by different sets extremely well. The dancers were ouvrières, mantua-makers, &c. &c., or filles, mostly the latter and shopmen, &c. &c.
