“Over the tree-tops I float thee a song,
Over the rising and sinking waves, over the myriad fields and the

Over the dense-packed cities all and the teeming wharves and ways,
I float this carol with joy, with joy to thee, O death,”

The cities we had learned about in school—
Till our lives wore out; our bodies lay among
The people we had killed and never seen.”
