How were smoke signals used?
May 18, 2011 3:57AM
Smoke signals were used to communicate with other people from far away when they were in trouble and needed help.
Old Indian tribes would have special signals to communicate to there own tribe that was far away.
Because anyone could see the smoke signals, the sender and the receiver of the smoke signals had their own special code.
