1Signaling heliographs, not solar-monitoring heliographs. The use of the term "heliograph" is not limited to sunshine recorders only. A heliograph can also be an instrument that uses the sun as a signaling device. The devices on these stamps are designed to directly reflect the sun's rays, unlike some other devices incorrectly labeled "heliograph" that are merely mechanical signaling or semaphore telegraphs. Those other devices reflect the sun so as to be seen, but they do not reflect the sun directly towards the viewer, via a mirror or mirrors, and are therefore not true heliographs in spite of the mis-applied name.
