Do you know the origin?

[Pamela Medland]

Good afternoon.
Does anyone know the origin of the phrase "the civilized hours?" This
was submitted as a query to the National Library of Canada on behalf of
a patron of my library, but the reference staff at NLC were unable to
locate the source of the phrase. They suggested I post this query on the
listserve. Please reply directly to me at pmedland at virl.bc.ca if you can
assist.
Thank you for your consideration,
Pam Medland
