The damper is a lid in the pipe’s throat.

You open it a finger. The vowel brightens. You close it a finger. The vowel hushes. Stack effect: warm cabin air sliding up, wind across the mouth, a bottle-note. You can make a haunting. That is the opposite of being hunted.

The chew continues, unimpressed by your concert, because porcupines do not care about flues.

You write: pipe vowel = wind + damper. not a miner.

The porch still has a snack thief. The cabin as a whole still wants a theory.

Warm air rises because it is lighter, a sentence from a classroom that finally has a pipe to live in. The stove is a heart. The flue is a throat. Wind is a thumb on the bottle-mouth. You have been haunted by weather’s musical instrument, which is funnier in pencil than in the dark, so you pencil it.
