John S. Carroll, Hsilgne Esrever (1948)
“ But occasionally you get someone who can hear all the way to fifteen or sixteen thousand. I figured Mariano's one of them. He must've heard horse-talk, but he's no good at languages and couldn't figure what they were saying. That's what he needed Bill for.""Okay, now I believe anything. I'll be seeing flying saucers next. But what's this peanut whistle that shrivels him up so? I don't hear any whistle.""Right. You don't, I don't and Bill doesn't. But Mariano does. It's the oscillator. I fed some of the 14,000 cycle output into a one-inch permanent magnet speaker. ”
