Did indians use smoke signals?
There was no universal language of smoke signals in the way that there was a universal sign language among the Plains tribes. Each tribe might have its own pre-arranged set of signals with specific meanings; since smoke can be seen for many miles and can be read just as easily by enemies as by friends, smoke signals were never used extensively. After contact with traders, mirrors were used much more effectively for signalling - the reflected flashes of sunlight can be directed in just one direction, preventing enemies from seeing the signals. Smoke signals were produced over a fire made with dry wood, grass and moss to produce smoke; a buffalo robe or trade blanket then trapped the smoke which was allowed to escape at intervals to produce long or short puffs. Naturally smoke signals only work in daytime and in areas with good visibility; they were not used in the woodlands areas where nobody would see them.
