Famous quotes containing the words thread and/or form:

    Tom Hyde, the tinker, standing on the gallows, was asked if he had anything to say. “Tell the tailors,” said he, “to remember to make a knot in their thread before they take the first stitch.” His companion’s prayer is forgotten.
    Henry David Thoreau (1817–1862)

    I never see that man without feeling that he is one to become personally attach’d to, for his combination of purest, heartiest tenderness, and native western form of manliness.
    Walt Whitman (1819–1892)
