Each Indian tribe had a different language.Many Indians never learned any language except their own.Do you know how Indians from different tribes talded to each other?They had two ways to talk without sound.One way was by sign language; another was by signals.
Sign language is a way of talking bu using sign.Indians used sign language when they met strangers.In this way,they could find out whether the stranger was a friend or an enemy.In Indian sign language,signs were made with the hand.One sign meant "man".Another meant"horse".To tell the time of day when something happened,an Indian pointed to the sky.He showed where the sun had been at the time.
Indians usually used signals when they wanted to send messages to someone far away.To make signals,an Indian might use a horse,He might use a blanket.Or he might use smoke,a mirror or five arrows.
To signal that he had seen many animals,an Indian rode his horse in a large circle.Sometime the Indians gave a signal like this and then went away to hide.This meant that there was danger.
The blanket signal was visible from far away.An Indian held the corner of a blanket in his hand.Then he began to wave the blanket from side to side in front of hom.An Indian could send many different signals with his blanket.
