I went to a 1 room school that had grades 1 through 8. It was heated by a big coal furnace in the basement, that the teacher had to get going early, so it would be warm for the kids. We used outhouses. Somedays, we would bring a potato to school and set them on a pan in the opening of the furnace and have a baked potato for lunch, slathered with home churned and highly salted butter. And the school was just wired for electricity, before I started 1st grade, because I rememember going to the Christmas programs, and everyone brought their kerosene lamps for better lighting. Quite the times.
