"Naturally the poor machines weren't able to cope with the letter. It was utterly outside their experience, beyond the furthest reach of their programming. It threw them into a terrible spasm. Pink Wastebasket is dead and at this very instant, if we're lucky, three police machines of the toughest blued steel are holding down Black Sorter and putting a muzzle on him." "Great Scott! It's incredible, Potshelter. And Pink Wastebasket dead? Take another tranquilizer, Potshelter, and hand over the tray." Krumbine received it with trembling fingers, started to pick up a big pink pill but drew back his hand from it in sudden revulsion at its color and swallowed two blue oval ones instead. The man was obviously fighting to control himself. He said unsteadily, "I almost never take doubles, but this news you bring--Good Lord! I seem to recall a case where someone tried to send a sound-tape through the mails, but that was before my time. Incidentally, is there any possibility that this is a letter sent by one _group_ of persons to another group? A hive or a therapy group or a social club? That would be bad enough, of course, but--" "No, just one single person sending to another." Potshelter's expression set in grimly solicitous lines. "I can see you don't quite understand, Krumbine. This is not a sound-tape, but a letter written in letters. You know, letters, characters--like books." "Don't mention books in this office!" Krumbine drew himself up angrily and then slumped back. "Excuse me, Potshelter, but I find this very difficult to face squarely. Do I understand you to say that one person has tried to use the mails to send a printed sheet of some sort to another?" "Worse than that. A written letter." "Written? I don't recognize the word." "It's a way of making characters, of forming visual equivalents of sound, without using electricity. The writer, as he's called, employs a black liquid and a pointed stick called a pen. I know about this because one hobby of mine is ancient means of communication." * * * * * Krumbine frowned and shook his head. "Communication is a dangerous business, Potshelter, especially at the personal level. With you and me, it's all right, because we know what we're doing." He picked up a third blue tranquilizer. "But with most of the hive-folk, person-to-person communication is only a morbid form of advertising, a dangerous travesty of normal newscasting--catharsis without the analyst, recitation without the teacher--a perversion of promotion employed in betraying and subverting." The frown deepened as he put the blue pill in his mouth and chewed it. "But about this pen--do you mean the fellow glues the pointed stick to his tongue and then speaks, and the black liquid traces the vibrations on the paper? A primitive non-electrical oscilloscope? Sloppy but conceivable, and producing a record of sorts of the spoken word."
