A flight of fancy in time and space which transcribes some incidents which take place on the planet of Mars, there's a literary, visionary quality here and an avoidance of the more mechanistic aspects of this medium. From the first expeditions from the earth in rocket ships, to the first settlements, this projects the war to come in which the earth is almost totally destroyed, and the return to Mars- now a wasted, lonely land, by some of its survivors. None of the complexities of concepts or formulae, this has an imaginative rather than technical ingenuity.
