A series dedicated to poems, published c. 1900–1935, the Radium Age sf-adjacent themes of which include: dystopia and utopia, far-out mathematics and the fourth dimension, Afro-futurism, catastrophe, future war, new technologies, scientific breakthrough, dehumanization, cosmic awe, disenchantment and unseen forces, unknowable aliens and singularity. Research and selection by Joshua Glenn; thematic index here.

  

There is a tree, by day,
That, at night,
Has a shadow,
A hand huge and black,
With fingers long and black.
All through the dark,
Against the white man’s house,
In the little wind,
The black hand plucks and plucks
At the bricks.
The bricks are the color of blood and very small.
Is it a black hand,
Or is it a shadow?

— Published in Caroling Dusk (1927), a seminal anthology edited by Countee Cullen. From what I can tell, this was its first publication.
