GUESSER GETS WEATHER RIGHT
While day-to-day weather forecasting enjoys reasonable accuracy, meteorologists have still to work out a basis for long-range prophecies. Nevertheless, Dr. C. F. Marvin, head of the U. S. Weather Bureau, is experimenting with a “scientific guesser.” Small balls are marked for a certain kind of weather. The balls are thoroughly mixed and poured into troughs. Their sequence, depending solely upon laws of chance, has proved strikingly similar to actual weather records.
