In an unpublished diary from 1901, written by a graduating senior of Chattanooga (Tenn.) High School, a girl named Dorothy records a week spent on Walden's Ridge visiting well-to-do friends whose families had summer homes above the heat of the city. A search for illustrative images led me to this atmospheric watercolor of Lookout Mountain (on the other side of the valley, but, hey!). Also to the artist, Emma Bell Miles. An educated woman who had studied art a writer, a poet, and a naturalist, she married a laborer on Walden's Ridge. Their life was hard. For anyone seeking to write historical fiction that encompasses the whole society of Walden's Ridge, her diary and her work are invaluable. And she's a reminder to researchers: Follow those tangents! They may lead to great discoveries.
