PENSIVE, on her dead gazing, I heard the Mother of All,
Desperate, on the torn bodies, on the forms covering the battle-
fields gazing;
(As the last gun ceased--but the scent of the powder-smoke linger'd;)
As she call'd to her earth with mournful voice while she stalk'd:
Absorb them well, O my earth, she cried--I charge you, lose not my
sons! lose not an atom;
And you streams, absorb them well, taking their dear blood;
And you local spots, and you airs that swim above lightly,
And all you essences of soil and growth--and you, my rivers' depths;
And you, mountain sides--and the woods where my dear children's
blood, trickling, redden'd;
And you trees, down in your roots, to bequeath to all future
trees, 10
My dead absorb--my young men's beautiful bodies absorb--and their
precious, precious, precious blood;
Which holding in trust for me, faithfully back again give me, many a
year hence,
In unseen essence and odor of surface and grass, centuries hence;
In blowing airs from the fields, back again give me my darlings--give
my immortal heroes;
Exhale me them centuries hence--breathe me their breath--let not an
atom be lost;
O years and graves! O air and soil! O my dead, an aroma sweet!
Exhale them perennial, sweet death, years, centuries hence.

Walt Whitman
