A book or possibly short story about 3 elves and a hole in the wall that speaks to them.
This story was read to the class by my third grade teacher at Hubbell School in Des Moines, IA, in 1949. I remember that we were entranced by it and insisted on making it into a drama. For our play the “elves” dressed in red long johns and the boy (Kenneth Brown) who devised the “hole” was cast in that role. I would be grateful if someone could direct me to it because I don’t remember the story and would like to see whether, as an adult, I can fathom what it was that charmed us so.
