If well written, every line of a poem can be a title:

Tom Hennen’s poem, reformatted, to show every line as a title.

The crow’s voice filtered through the walls of the farmhouse

sounds of a rusty car engine turning over

clouds on a north wind that whistles softly and cold

spruce trees planted in a line on the south side of the house weave and scrape at the air

I’ve walked to a far field to a fence line of rocks where I am surprised to see soft mud this raw day

no new tracks in the mud

desiccated grass among the rocks

a bare grove of trees in the distance

a blue sky thin as an eggshell with a crack of dark geese running through it

their voices faint and almost troubled as they disappear in a wedge that has opened at last the cold heart of winter.
