'Story is of the type that does not need very much science. Explorers journey into the Earth in a vessel called the Mole, and crash in the midst of some ancient Romans twelve miles beneath the surface. After fighting some more ancient Romans who live in a neighbouring cave, the whole race is wiped out by floods. Hero and sidekick escape with respective girlfriends whom they found down there. That summary is not meant to ridicule the book, but is shortened to save space. It seems that in Heming we have a good hope for the future. His style is still crude but his ideas are good.'
