Here is the text:
O SUN of real peace! O hastening light!
O free and extatic! O what I here, preparing, warble for!
O the sun of the world will ascend, dazzling, and take his height—and you too, O my Ideal, will surely ascend!
O so amazing and broad—up there resplendent, darting and burning!
O vision prophetic, stagger’d with weight of light! with pouring glories!
O lips of my soul, already becoming powerless!
O ample and grand Presidentiads! Now the war, the war is over!
New history! new heroes! I project you!
Visions of poets! only you really last! sweep on! sweep on!
O heights too swift and dizzy yet!
O purged and luminous! you threaten me more than I can stand!
(I must not venture—the ground under my feet menaces me—it will not support me: O future too immense,)--
O present, I return, while yet I may, to you.
