MESSAGE CORD  A bundle of animal hairs signals the beginning of a sequence of twisted and knotted cords on an 18th century khipu from a Central Andean village. A bright red tuft of deer hair is followed by a woven cone of hairs from different animals mixed with metallic fibers. New research suggests this and another khipu contain a type of writing.
