Famous quotes containing the words stem and/or drill:

    Apples? New Hampshire has them, but unsprayed,
    With no suspicion in stem end or blossom end
    Of vitriol or arsenate of lead,
    And so not good for anything but cider.
    Robert Frost (1874–1963)

    Swift blazing flag of the regiment,
    Eagle with crest of red and gold,
    These men were born to drill and die.
    Point for them the virtue of slaughter,
    Make plain to them the excellence of killing
    And a field where a thousand corpses lie.
    Stephen Crane (1871–1900)
