The quote below is from the Gettysburg Address.
"We have come to dedicate a portion of that field as a final resting-place for those
who here gave their lives that that nation might live. It is altogether fitting and
proper that we should do this. But in a larger sense, we cannot dedicate, we cannot
consecrate, we cannot hallow this ground. The brave men, living and dead who
struggled here have consecrated it far above our poor power to add or detract."
