Yámana
Yámanas used fire to send messages by smoke signals, for instance if a whale drifted ashore. The large amount of meat required notification of many people, so that it would not decay. They might also have used smoke signals on other occasions, thus it is possible that Magellan saw such fires (which inspired him to name the landscape Tierra del Fuego) but he may have seen the smoke or lights of natural phenomena
Noon Gun
Noon Gun time signalling was used to set marine chronometers in Table Bay.
AboriginAboriginal Australians in the Western Desert would send up smoke to notify others of their presence, particularly when entering lands which were not their own. 'Putting up a smoke' would often result in nearby individuals or groups replying with their own signalsal Australians
