How does Alice Munro use imagery in Meneseteung?

Imagery:

"Soon this glowing and swelling begins to suggest words—not specific words but a flow of words somewhere, just about ready to make themselves known to her. Poems, even."

"You see them going around with notebooks, scraping the dirt off gravestones, reading microfilm, just in the hope of seeing this trickle in time, making a connection, rescuing one thing from the rubbish."
