The indigenous people developed an international sign language through a system of gestures by which intricate conversation could be carried on as a means of communication between tribes. The natives used a written language by using some of the English alphabet mixed with new characters called Syllabary. Prior to this the people placed pictographs or symbols on pottery, weavings, silverwork, leather, rock and sand paintings. Symbols ranged from motifs of birds, clouds, rain designs, animal tracks to many forms of nature in the environment.
