Trivia

• A "divining rod" (also referred to as a "dowsing rod" and a "witching rod") is a Y- or L-shaped twig or rod used during dowsing, a type of divination that specializes in the search of ground water and other valuable objects without the use of a scientific apparatus.
• The poem that Garrett recites is a verse from The Book of the Thousand Nights and a Night by Richard Francis Burton, from the final chapter "Conclusion". The full verse is as follows:

She comes like fullest moon on happy night,
Taper of waist with shape of magic might.
She hath an eye whose glances quell mankind,
And ruby on her cheeks reflects his light.
Enveils her hips the blackness of her hair—
Beware of curls that bite with viper-bite!
Her sides are silken-soft, that while the heart
Mere rock behind that surface 'scapes our sight.
From the fringed curtains of her eyne she shoots
Shafts that at furthest range on heart alight.
