We all understood how that worked. The device consist of a solid glass sphere, typically about 4 inches in diameter, that concentrates the sun's rays to an intense spot on a calibrated paper, resulting in a burn. The Campbell–Stokes Sunshine Recorder has remained essentially unchanged since then. In 1879, Irish physicist replaced the wooden frame with metal and added removable paper cards to record the burns. A sunshine recorder is a device that records the amount of sunshine at a given location or region at any time. As the sun moved across the sky, the beam scorched a path across the wood. The sunshine recorder is a kind of sundial, which the corre- sponding burning point should indicate the true solar time.
