Breaks for a chapter, searches to find the number to give it. . . .
Realizes that the last chapter took up as many pages as the first five -- over a hundred. Suspects that this is going to need some refinement.
Chapter breaks are super-strength paragraph breaks, and generally scene breaks as well. To throw emphasis on things. Chapter breaks work particularly well for emphasizing the last sentence of the chapter in my experience.
But a five-page paragraph is too much, and so too with these. It's not that big a unit.
Ah, the delights of writing.
