Famous quotes containing the words ground and/or glass:

    “Keep out of Chancery.... It’s being ground to bits in a slow mill; it’s being roasted at a slow fire; it’s being stung to death by single bees; it’s being drowned by drops; it’s going mad by grains.”
    —Charles Dickens (1812–1870)

    “... this I conceive to be no time to prate of moral influences. Our men’s nerves require their accustomed narcotics and a glass of whiskey is a powerful friend in a sunstroke, and these poor fellows fall senseless on their heavy drills.”
    —Clara Barton (1821–1912)
