Clark Rogers is an inventive genius. He has mastered the prairie dog question. “Buy some good sized fish hooks with eyelets on top,” said Mr. Rogers, “and nail two or three of them on a narrow board. Put the board in the dogs den. The dogs will come up all right, but they will always slide down, when they are impaled on the hooks. It never fails to catch them, and the method is both cheap and rapid. By proper attention one man can catch a whole town of prairie dogs in a few days.”
