Smoke signal
The smoke signal is one of the oldest forms of long-distance communication. It is a form of visual communication used over a long distance. In general smoke signals are used to transmit news, signal danger, or to gather people to a common area.

Misuse of the smoke signal is traditionally considered to have contributed to the fall of the
Smoke signals remain in use today. The College of Cardinals uses smoke signals to indicate the selection of a new Pope during a papal conclave. Eligible cardinals conduct a secret ballot until someone receives a vote of two-thirds plus one. The ballots are burned after each vote. Black smoke indicates a failed ballot, and white smoke means a new Pope has been elected.
Colored smoke grenades are commonly used by military forces to mark positions, especially during calls for artillery or air support.
Smoke signals may also refer to smoke-producing devices used to send distress signals.[6][7]
Examples
Native Americans
Lewis and Clark's journals cite several occasions when they adopted the Native American method of setting the plains on fire to communicate the presence of their party or their desire to meet with local tribes.[8]

Noon Gun
The Cape Town Noon Gun, specifically the smoke its firing generates, was used to set marine chronometers in Table Bay.
Aboriginal Australians
Aboriginal Australians throughout Australia have used smoke signals for various purposes—[13][14][15][16] sometimes to notify others of their presence, particularly when entering lands which were not their own.[13] Sometimes used to describe visiting whites, smoke signals were the fastest way to send messages.[16] Smoke signals were sometimes to notify of incursions by hostile tribes, or to arrange meetings between hunting parties of the same tribe. This signal could be from a fixed lookout on a ridge or from a mobile band of tribesman.[15] "Putting up a smoke" often promoted nearby individuals or groups to reply with their own signals.[14][15] Different colours of smoke (black, white or blue, depending on whether the material being burnt was wet grass, dry grass, reeds or other materials) were used to convert information, as was the smoke's shape (a column, ball or ring), allowing a messaging system sophisticated enough to include the names of individual tribesmen.[15] Like other means of communication, signals could be misinterpreted. In one recorded instance, a smoke signal reply translated as "we are coming" was misinterpreted as joining a war party for protection of the tribe, when it was actually to indicate hunting parties coming together after a successful hunt.[15]
