    Shea—they call him Scholar Jack—
    Went down the list of the dead.
    Officers, seamen, gunners, marines,
    The crews of the gig and yawl,
    The bearded man and the lad in his teens,
    Carpenters, coal-passers—all.
    Joseph I. C. Clarke (1846–1925)

    When the rock was hid by the surges’ swell,
    The mariners heard the warning bell,
    And then they knew the perilous rock,
    And bless’d the Abbot of Aberbrothok.
    Robert Southey (1774–1843)

    If there is nothing new on the earth, still the traveler always has a resource in the skies. They are constantly turning a new page to view. The wind sets the types on this blue ground, and the inquiring may always read a new truth there.
    Henry David Thoreau (1817–1862)
