This is another situation where context and my personal preferences may outweigh any kind of commentary on intrinsic value. But what of it?
Simply put, when I read in Filmfax (Number 155) that the Richard Lyford 1930s silent film As the Earth Turns was based upon this novella length story, I knew that I would like it no matter what. Increasing interest was the fact that I had once read Arthur Train's tale Mortmain which ~ oddly enough ~ was also filmed silently. (Train and Robert Williams Wood also wrote a sequel to TMWRtE called The Moon Maker. That I have not read ... yet.)
OK. Let's put prejudice aside (if that's possible) for a second. Some of the dialogue is creaky but in a good hundred year old way. The writing is bit uneven. For instance, the first part of the book has short chapters. However, the last chapter is a doozy length-wise. This makes me wonder who wrote what. I suppose that I enjoyed the first half better since the film followed it more closely. However, the entire book ~ while no literary masterpiece ~ was both fun and poignant which is a difficult combination to pull off. (By the way, unlike the movie, the book lacked "dames").
Certainly a wide variety of science fiction trappings were there: alternate history, an earth moving apparatus (as in the entire planet!), futuristic flying machines, advanced (for the time) radio technology, "vortex guns" and even the appearance of H.G. Wells as a character! (Stuff like that makes me a happy fella! I suppose that I'm a pushover.)
Maybe others won't love this story as much as I. Don't have any way of knowing. I have to say nonetheless that I found it a treat.
