Leaving Ardis after his first summer there, Van Veen (the narrator and main character in VN’s novel Ada, 1969) asks Bouteillan (the French butler at Ardis) not to quote Delille to him:
On a sunny September morning, with the trees still green, but the asters and fleabanes already taking over in ditch and dalk, Van set out for Ladoga, N.A., to spend a fortnight there with his father and three tutors before returning to school in cold Luga, Mayne.
