Three are of sandy matrix, one of clay. They are typical in form, with flat triangular faces and mildly rounded edges (Fig. 6cc). The sandy objects are larger than the clay, 5.3 to 6.8 cm. in length of triangle margins:	the clay object is 4 to 4.3 cip. There is no difference in
color, appearance or composition of paste from other objects.
The Claiborne tetrahedrons and two recently found at Poverty Point site (p. 24-) are the first from another site than Jaketown since the description of tetrahedrons in the report of that site (Ford, Phillips and Haag 1955). The tetrahedrons at Jaketown were in large numbers, found on the talus slope of Mound A and stratigraphically above the levels containing Poverty Point objects. They were associated with Tchula sherds. It was postulated that these tetrahedrons were made differently and served a function different from the baked clay balls of the Poverty Point period. The only other recorded occurrence of tetrahedral objects was by Clarence B. Moore (1913) at the Montgomery Place on Bayou Majon, in Franklin Parish, Louisiana. He found 25 of these objects in a circular firepit, one foot in depth and 32 inches in diameter, at the base of a conical mound. The tetrahedrons were described as three to four inches in height with rounded faces. The illustrated objects were stated to be full size and in the photograph they measure 7 to 9 cm. Sizes of the objects from Jaketown were not given nor do the illustrations include a scale, but they appear to be slightly larger than most of the Poverty Point objects from Jaketown. The presence of tetrahedrons at Claiborne and Poverty Point sites, in the midden with other types and in the absence of Tchula pottery (at Claiborne), suggests that this type may occur, rarely, at a time earlier than Tchefuncte-Tchula and along with other Poverty Point objects.
