Famous quotes containing the word hall:

    “While there we heard the Indian fire his gun twice.... This sudden, loud, crashing noise in the still aisles of the forest, affected me like an insult to nature, or ill manners at any rate, as if you were to fire a gun in a hall or temple.”
    —Henry David Thoreau (1817–1862)
