Interpolation Sounds

Over and through the burial chant,
Organ and solemn service, sermon, bending priests,
To me come interpolation sounds not in the show--plainly to me,
    crowding up the aisle and from the window,
Of sudden battle's hurry and harsh noises--war's grim game to sight
    and ear in earnest;
The scout call'd up and forward--the general mounted and his aides
    around him--the new-brought word--the instantaneous order issued;
The rifle crack--the cannon thud--the rushing forth of men from their
    tents;
The clank of cavalry--the strange celerity of forming ranks--the
    slender bugle note;
The sound of horses' hoofs departing--saddles, arms, accoutrements.
