Famous quotes containing the word allegheny:
“Wachusett hides its lingering voice
Within its rocky heart,
And Allegheny graves its tone
Throughout his lofty chart.
Monadnock, on his forehead hoar,
Doth seal the sacred trust,
Your mountains build their monument,
Though ye destroy their dust.”
—Lydia Huntley Sigourney (1791–1865)
