Photo Evidence: Brisbane Bureau of Meteorology Uses a Crystal Ball, 1938.

People often accuse the Bureau of Meteorology of using a crystal ball in it's work and at last they are vindicated. Not quite a tool for weather forecasting but for measuring sunlight. Caption reads:

Three perfect sunshine days left their mark on the recording device at the Weather Bureau;.Sun rays are concentrated through a crystal magnifying condenser and burn furrows on a slowly-revolving card, marked in hours. Left : Yesterday's card being examined by an official. Right:.The sunshine records for Sunday, Monday, and Tuesday.
