The following text is from Charlotte Brontë’s 1847 novel Jane Eyre. Jane, the narrator, works as a governess at Thornfield Hall.

I went on with my day’s business tranquilly; but ever and anon vague suggestions kept wandering across my brain of reasons why I should quit Thornfield; and I kept involuntarily framing advertisements and pondering conjectures about new situations: these thoughts I did not think to check; they might germinate and bear fruit if they could.
