" Tom got out a bit of paper and carefully unrolled it. Huckleberry viewed it wistfully. The temptation was very strong. At last he said: "Is it genuwyne?" Tom lifted his lip and showed the vacancy. "Well, all right," said Huckleberry, "it's a trade." Tom enclosed the tick in the percussion-cap box that had lately been the pinchbug's prison, and the boys separated, each feeling wealthier than before. "
