Paul Laurence Dunbar,
The Heart Of Happy Hollow — Schwalliger's Philantropy
(1904)
“ But the operator of the shell game had caught sight of the bills, and it was like the scent of blood to the tiger. His eye was on the simple Negro at once, and he called cheerfully:"Come up, uncle, and try your luck. See how I manipulate this ball. Easy enough to find if you're only lucky." He was so flippantly shrewd that his newness to the business was insolently apparent to Schwalliger, who knew a thing or two himself. Schwalliger smiled again and shook his head. ”
