War is Kind & Other Lines/"I have heard the sunset song of the birches,"

"I have heard the sunset song of the birches, A white melody in the silence, I have seen a quarrel of the pines. At nightfall The little grasses have rushed by me With the wind men. These things have I lived," quoth the maniac, "Possessing only eyes and ears. But you — You don green spectacles before you look at roses." When I am fast asleep, Then tell my love the secret That I have died to keep.
