Bob from Rockford, Illinois, recalls that forty years ago when he was in the Navy, his instructors would stamp their foot to emphasize a particular point that might be on the test later. They referred to this action as horsing up the students, and the students called their group study sessions horse sessions and referred to their large notebooks as horse notes. What do horses have to do with the curriculum studied by the Navy’s nuclear-power specialists? The answer may have to do with horse blankets. This is part of a complete episode.
