"Watch!" answered Mr. Wales, and taking a big copper coin from his pocket he threw it toward the men. Before it hit the surface of the water all three were after it. One caught it as it fell, but another knocked it out of his hand, and then all three dived for it. The girls crowded to the side of the boat to watch proceedings, and sure enough, though the boatman said the water was twenty feet deep, it was so clear that they could see distinctly when one of the men, feeling along the bottom, reached the coin and, sputtering and coughing, came up to the surface with it. Instead of going back to his boat to rest, he calmly put the coin in his mouth, and paddled lazily about, joining in the shouts of his companions for more pennies.
