standpoint, to find out if it could be found it might be possible to disrupt the pattern. After he had been at it for about a week, Terry came into the lab in a disgruntled mood at the completion of a work period. "You look as if Papa gave you a spanking," said Underwood. "Why the downcast mood?" "I think I'll resign and go back to the museum. It's useless to work on this puzzle any longer." "How do you know?" "Because it doesn't follow the laws of semantics with respect to language." "Maybe the laws need changing." "You know better than that. Look, you are as familiar with Carnovan's law as I am. It states that in any language there is bound to be a certain constant frequency of semantic conceptions. It's like the old frequency laws that used to be used in cryptographic analysis except a thousand times more complex. Anyway, we've made thousands of substitutions into Carnovan's frequency scale and nothing comes out. Not a thing. No concept of ego, identity, perfection, retrogression, or intercourse shows up. The only thing that registers in the slightest degree is the concept of motion, but it doesn't yield a single key word. It's almost as if it weren't even a language." "Maybe it isn't." "What else could it be?" "Well, maybe this thing we've found is a monument of some kind and the inscriptions are ritualistic tributes to dead heroes or something. Maybe there's no trick at all about the radiation business. Maybe they used that frequency for common illumination and the inscription was arranged to show up just at night. The trouble with you strict semanticists is that you don't use any imagination." "Like to try a hand at a few sessions with Papa Phyfe?" "No, thanks, but I do think there are other possibilities that you are overlooking. I make no claim to being anything but a strictly ham semanticist, but suppose, for example, that the inscriptions are not language at all in the common sense." "They must represent transfer of thought in some form." "True, but look at the varied forms of thought. You are bound down to the conception of
