"... many theories are presented with an emphasis on possible military, biodynamic, and/or natural origins...." ________________ MYSTERY OF THE HUM by Michael Theroux COPYRIGHT 1997 Published by Borderland Sciences Research Foundation This book is an introduction to the world-wide phenomenon of the HUM. The author has at many times actually heard the HUM, and has extensively researched the phenomenon for several years. In this book, the author covers the detailed history of the HUM, current manifestations, and up-to-date research projects. While there is no attempt to definitively presume the HUM's source, many theories are presented with an emphasis on possible military, biodynamic, and/or natural origins. Special considerations have been given to new theories which complete all of the requirements of this enigmatic and anomalous phenomenon. This title is near completion, but as it is a work in progress, the author welcomes any information offered.
