- Profile of Jack Baumgartner in Plough: “Downstairs, I start the hot water for coffee. I stir the coals in the wood stove we heat our home with, remove some ashes, and place two mulberry logs on the embers to ignite. This is priestly work and an art near to my heart, maintaining a fire for my family. It is a part of my worship.”
- “Farming the Universe.” Much the same material as above, but written by Jack himself.
