I have excellent reason to be particularly grateful to four experts in writing this conclusion of the Talent (aka The Tower and the Hive) series. Dr. Jack Cohen of the University of Warwick and I discussed how I could solve the problem of colonizing Hivers. So I had a structure to begin with. I was dumbfounded to discover that my dictionary had only five lines about the very complex subject of pheromones. The Web came to my assistance and I asked for help, which was quick in coming from Jonathan Brecher and Louis Culot of CambridgeSoft on their special expertise, both as generalists and for specific knowledge about pheromones. We had some lively E-mail exchanges, since Jonathan knew of Lyon’s Pride when I approached him for assistance. His colleague Louis Culot supplied additional details. I wish also to thank Bibb Graves from Hewlett Packard Houston for a description of gas chromatographs, which register the strength and composition of pheromones. We extrapolated—as is the function of science fiction—that the future would miniaturize what are actually large and cumbersome instruments. But then most current gas chromatographs (GCs) have altered considerably from their original forms, and no doubt will have altered even more by the time of The Tower and the Hive.
