Mark Twain,
Little Bessie
(1908)
“ One fly produces fifty-two billions of descendants in 60 days in June and July, and they go and crawl over sick people and wade through pus, and sputa, and foul matter exuding from sores, and gaum themselves with every kind of disease-germ, then they go to everybody's dinner-table and wipe themselves off on the butter and the other food, and many and many a painful illness and ultimate death results from this loathsome industry. Mamma, they murder seven thousand persons in New York City alone, every year -- people against whom they have no quarrel. ”
