UNKNOWN DEAD, NATIONAL CEMETERY.–One of the most pathetic sights of a trip over the Gettysburg field is the section in the National Cemetery set apart for the unknown. There are 979 that are totally unknown as to name, state or organization. Small markers of marble, as are shown to the right of the illustration, stand at each grave and are simply numbered. To the left is a section of the known dead, where substantial granite slabs serve as headstones. The handsome New York State monument is seen near the center.
