The Lunar Chrysalis by Raymond Z. Gallun:
Science Fiction Inventions, Technology and Ideas

"THE last few years seem to have brought us some unaccountable seasonal changes. What if the changes should become more marked, and very much more serious, even to the point of injuring us? What would humanity do then? Such a calamity is, of course, not likely to happen for many thousands of years, but it is an interesting subject for speculation.


(From 'The Lunar Chrysalis' by Raymond Gallun)

One very marvelous solution — providing the method can be discovered, or invented — is offered by Mr. Gallun in this excellently written story of scientific interest. "
