Chapter nineteen is about the “The Green Machine”. In the chapter two elderly women, Miss Fern and Miss Roberts, take refuge in their attic after they accidentally run over Mister Quartermain while riding the Green Machine, believing him to be dead. Huddling together, they recall the time when they bought the Green Machine from a salesman as a noiseless, smooth form of transportation. The first week on the Green Machine went by like a dream, until the accident with Mister Quartermain. Fern and Roberts lament on how they did not stop or at least get help for him, and then resolve to not drive the Green Machine ever again. Later on, they learn that Mister Quartermain did not die after all.
