Famous quotes containing the word heart:

    The death of William Tecumseh Sherman, which took place to-day at his residence in the city of New York at 1 o’clock and 50 minutes p.m., is an event that will bring sorrow to the heart of every patriotic citizen. No living American was so loved and venerated as he.
    Benjamin Harrison (1833–1901)

    Sweet is the day of sacred rest;
    No mortal cares shall seize my breast;
    O may my heart in tune be found
    Like David’s harp of solemn sound.
    Isaac Watts (1674–1748)

    Twelve o’clock! It is the natural centre, key-stone, and very heart of the day. At that hour, the sun has arrived at the top of his hill; and as he seems to hang poised there a while, before coming down on the other side, it is but reasonable to suppose that he is then stopping to dine; setting an eminent example to all mankind.
    Herman Melville (1819–1891)
