An early morning customer in an optician's shop was a young woman with a determined air. She addressed the first salesman she saw. "I want to look at a pair of eyeglasses, sir, of extra magnifying power."
"Yes, ma'am," replied the salesman; "something very strong?"
"Yes, sir. While visiting in the country I made a very painful blunder which I never want to repeat."
"Indeed! Mistook a stranger for an acquaintance?"
"No, not exactly that; I mistook a bumblebee for a black-berry."
