Famous quotes containing the words canal and/or ear:

    My impression about the Panama Canal is that the great revolution it is going to introduce in the trade of the world is in the trade between the east and the west coast of the United States.
    William Howard Taft (1857–1930)

    ‘Stay—stay with us!—rest—thou art
    weary and worn!’—
    And fain was their war-broken soldier to stay;—
    But sorrow return’d with the dawning of morn,
    And the voice in my dreaming ear melted away.
    Thomas Campbell (1774–1844)
