color. (See Plate VII A). This two-toned mound fill may have 
been purposely used in the mound construction. 
Just west of the center of the axis of the mound the re- 
mains of a burned wooden rectangular structure were found at 
the base of the mound. Traces of charred vertical posts form- 
ing the wall of this structure were clearly visible, as well as a 
small round clay lined fireplace with a concave bottom near 
the center. (See Plate VII B). The posts were more or less 
completely intact indicating that the wall posts were 10 to 15 
centimeters in diameter and had been placed so that they touched 
each other, much in the manner of a palisade. They had been 
inserted at a depth of 20 to 25 centimeters but no apparent ditch 
could be found into which they had been placed so that the posts 
appear to have been driven into the ground. The bottoms were 
slightly rounded but not pointed or wedge shaped. The long 
axis base of the house was parallel to the long axis of the mound. 
Between the northern end of this structure and the center 
just west of the longitudinal axis of the house was found an 
extended burial, located 15-20 centimeters below the floor. 
This burial was without a head and almost entirely calcined. 
Below the bones were remnants of a coarse matting with twined 
weaving possibly of shredded bark, One small section of a much 
more finely woven twined material lay between a fragment of 
the left tibia and the twined matting and had been apparently 
a portion of the clothing of the individual. As there was no 
evidence of burning beneath the skeleton it is believed that 
the structure had been erected over the deceased and then 
burned, and this burned the burial. A deep and narrow pit 
filled with dark disintegrated vegetable matter lay below the 
mound base 2.5 meters east of the northern half of the house 
Structure. 
It is noteworthy that less than a dozen sherds and no arti- 
facts were found in the mound fill and in the pits excavated 
around the mound. These few were Imperial Plain sherds. On 
One of them was a duck’s bill effigy from an effigy flange bowl. 
It had a black slip. Another sherd with a black slip belonged
