inca
The Inca had no system of writing, but they could send messengers to repeat what they said. The Inca also had a large road system, even bigger than the Romans.
They used weaving as a means of representing ideas. Using wool sheared from llamas and alpacas, as well as many colorful plant dyes, the inca wove images into the fabrics they wore and traded.
The Inca built stone roads which allowed runners to carry verbal messages. The runners worked in relay teams stationed along the roads. One runner told the message to the next. Messages could travel 150 miles a day along these stone roads. This system of communication was important to the Inca because their empire spread out over thousands of mile.
