As spring returns, the lilacs blossom, and the planet Venus "nearly dropp'd in the western sky," the poet mourns the loss "of him I love.".He mourns the "powerful western fallen star" now covered by "black murk" in the "tearful night," and he is "powerless" and "helpless" because the cloud around him "will not free my soul.".A shy, solitary thrush, like a secluded hermit, sings a song which is an expression of its inmost grief.The purple color of the lilac, indicating the passion of the Crucifixion, is highly suggestive of the violence of Lincoln's death.It describes the journey of the coffin through natural scenery and industrial cities, both representing facets of American life.The thrush's song in section 4 is a prelude to the journey of the coffin which will pass "over the breast of the spring" through cities, woods, wheat fields, and orchards.But "in the midst of life we are in death," as it says in the Book of Common Prayer, and now the cities are "draped in black" and the states, like "crape-veil'd women," mourn and salute the dead.Somber faces, solemn voices, and mournful dirges mark the journey across the American continent.The song of the hermit thrush finally makes the poet aware of the deathless and the spiritual existence of Lincoln.The pictures on the dead president's tomb, he says, should be of spring and sun and Leaves, a river, hills, and the sky, the city dense with dwellings, and people at work — in short, "all the scenes of life.".The "body and soul" of America will be in them, the beauties of Manhattan spires as well as the shores of the Ohio and the Missouri rivers — all "the varied and ample land.".The song has a liberating effect on the poet's soul, although the star still holds him, as does the mastering odor" of the lilac.In this cycle the description of natural objects and phenomena indicates the breadth of Lincoln's vision, and the "purple" dawn, "delicious" eve, and "welcome" night suggest the continuous, endless cycle of the day, which, in turn, symbolizes Lincoln's immortality.The poet remembers that one day while he sat in the peaceful but "unconscious scenery of my land," a cloud with a "long black trail" appeared and enveloped everything.These dead soldiers are happy in their resting places, but their parents and relatives continue to suffer because they have lost them.As the coffin passes him, the poet salutes it, reminding himself that the lilac blooming in the dooryard will return each spring.The star, the bird, and the lilac join with the poet as he bids goodbye to Lincoln, his "comrade, the dead I loved so well.".
