Sometimes they used a carved wooden paddle to stamp designs onto the entire outer surface of the vessel. At other times they decorated only the top half of the pot with designs formed by incising lines or pressing tools into the damp clay. The colors of the clay were usually tan, brown, gray or black. On rare occasions vessels were colored red on the outside or shaped into human effigies. [Illustration: Troyville-Coles Creek: a-e, Vessel Rim Sherds; f-h, Stone Points (½ actual size)] Late in the Troyville-Coles Creek Period, changes began to occur. Indians in the northwestern part of the state developed close ties with people living north and west of them, while those in the east became more closely aligned with people to their east. Descendants of the Troyville-Coles Creek people were Indians of the Caddo and of the Plaquemine-Mississipian cultures. Caddo By about A.D. 800, descendants of the Troyville-Coles Creek people living in northwestern Louisiana had developed close ties with people in southeastern Oklahoma, northeastern Texas and southern Arkansas. From this region emerged the Caddo Culture. These Indians developed a fine, new style of pottery, and used special ornaments and objects made from imported materials. They also performed elaborate burials of upper class people. There was little change in the daily life of the ordinary Indians. Most people spent their lives in small villages and hamlets near streams or lakes. Many trends established in earlier generations persisted. New garden crops such as beans were introduced and were added to the corn, squash, gourds and native plants already grown. It seems that people from these small settlements were governed by high status individuals living at the ceremonial centers. Common people were probably required to help build mounds, to supply food, or to make tools or special objects for their rulers. They gathered at the centers when they were needed or when special ceremonies or festivals were celebrated. [Illustration: Gahagan Site] At the Gahagan Site, in Red River Parish, early Caddo Indians built mounds and a village around a large open plaza. One mound had three deep shaft burials, each with three to six bodies and 200 to 400 burial offerings. Some of the unusual burial objects from this site are two clay human effigy pipes, two copper cutouts of human hands, two copper long-nosed mask ear ornaments, two frog effigy pipes, and numerous triangular stone blades called “Gahagan knives.” Early Caddo people continued the Troyville-Coles Creek custom of constructing ceremonial centers with mounds around a central plaza. They built temples or special buildings on top of the mounds and also dug graves into the mounds for burials of important people.
