From another review in The Edinburgh Literary Journal, July-Dec, 1830, page 285
FLOW, RIO VERDE!
By Mrs Hemans.
"Flow, Rio Verde!
In melody flow;
Win her that weepeth,
To slumber from woe:
Bid thy wave's music
Roll through her dreams;
Grief ever loveth
The kind voice of streams.
"Bear her lone spirit
Afar on the sound,
Back to her childhood,
Her life's fairy ground:
Pass like the whisper
Of love that is gone:
Flow, Rio Verde,
Softly flow on!
"Dark, glassy water!
So crimson'd of yore!
Voices of sorrow
Are known to thy shore:
Thou shouldst have echoes
For grief's deepest tone—
Flow, Rio Verde,
Softly flow on!"
