Dr. Hackensaw's Secrets Some Minor Inventions by Clement Fezandie:
Science Fiction Inventions, Technology and Ideas
"DOCTOR HACKENSAW has his secrets, but most of our readers make no secret of the fact that they appreciate the doctor's work. The author has the knack - or perhaps we should call it, the quality — of helping the doctor present the most extraordinary, wonderful things in such a manner as to make than appear both plausible and passible. Here this ingenious inventor, explains to us some of his comparatively simple inventions, giving us a machine with which to can bread, another to do away with the human typist — and even- translator - entirely — etc. — all useful machines. Still he is dissatisfied — so he always goes ahead, ever seeking new improvements. Usually he succeeds. Here is food for thought — and experimentation — even if the story is humorously told, it is full of interest and new ideas."
