Famous quotes containing the word core:

    “The threadbare trees, so poor and thin,
    They are no wealthier than I;
    But with as brave a core within
    They rear their boughs to the October sky.
    Poor knights they are which bravely wait
    The charge of Winter’s cavalry,
    Keeping a simple Roman state,
    Discumbered of their Persian luxury.”
    —Henry David Thoreau (1817–1862)
