Whistle

Definition and stakes

Allen French,  St. Nicholas — The Runaway (1873)

“ It was like the noise of machinery, and yet was unlike. At any rate, it was an irregular, creaky, jumpy kind of machinery. It continued monotonously on and on; it was, he reflected, a pretty soothing kind of noise to sleep to. And then a new sound came to his ears: a cheerful and yet a thoughtful whistle. A man's whistle—a boy would not whistle so thoughtfully. ”

Robert Emmet Barrett,  Treading the Narrow Way

“ It is better to whistle than to groan. It will make some heart lighter to hear you whistle than to groan. If you can’t whistle a tune sizzle something through your teeth, there’s cheer in it for some one. No matter how worrisome, difficult or perplexing the problem is, don’t worry or brood over it. ”
