Just in case you feel that way we would like to tell you about a book recently received from overseas. It deals with some new ideas about the use of ultra high-frequency radiations. It mentions such things as special valves with positive potentials on the grids and negative potentials on the plates, just to get the electrons mixed up so that the valves will oscillate without regeneration. Like a fairy story read the chapters about radio transmission from lenses made of ebonite, instead of aerials. Further details cannot be revealed at the moment, but you can take it for granted that when peace returns the wartime research will be found to have paved the way for radio development on a scale never before imagined.
