Where she sleeps, no moonlight shines
No pale beam unbidden creeps.
Darkest shade the place enshrines
Where she sleeps.

Like a diamond in the deeps
Of the rich unopened mines
There her lovely rest she keeps.

Though the jealous dark confines
All her beauty, Love's heart leaps.
His unerring thought divines
Where she sleeps.

Robert Fuller Murray
