Got the idea of killing the monster from a splash of rocket fuel on the bank of the stream and my memory of the pain in the early feelings. But it was nothing compared to the feeling when the acid hit that damned mass of green slime! Even though my brain was screaming at me, I felt good. I should put a couple of hundred gallons into the stream just to make sure--but I can't afford it. I need the fuel to run the generators to propagate the wave that'll bring me home if someone hears it. And they'll hear it all right. My luck is in. Now I'm going to sleep--_sweet sleep that knits the ravelled sleeve of care_--Shakespeare, old man, you had a phrase for everything! I love you. I love everything. I even feel sorry for that poor plant ... of guilt. It couldn't help the fact that my jets set up a mutation. And being intelligent it _had_ to be curious. Of course, no one would believe me if I started talking about intelligent algae. But what's so odd about that? Even the most complex life forms are just aggregations of individual cells working together. So if a few individual cells with rudimentary data-storage capacity got the idea of uniting why couldn't they act like a complex organism? * * * * * It is useless to speculate on what might have happened had that thing lived. But it's dead now--burned to death in acid. And although destruction of intelligent life is repugnant to me, I cannot help feeling that it is perhaps better that it is gone. Considering how rapidly it developed during its few weeks of life, and the power it possessed, my mind is appalled at its potential. I've had my experience and that's enough. Lord! but I'm tired. I feel like a wrung-out sponge. Guess I'll rest for a little while ... ... and received a reply to my signal! They heterodyned it right back along my own beam. They'll be landing in a week. I don't think I'll take this manuscript with me. I couldn't use it--and somehow I don't feel like burning it. Maybe I'll make a time capsule out of it. It will be amusing to speculate about what sort of a reaction it'll provoke, providing it is ever read. I can see them now, huge-headed humans, wrinkling their noses and saying "Intelligent algae--fantastic--the man must have been mad!"
