A second trench was put down be- tween R9 and RIO and designated the RIO trench. A third trench was designated the L9 trench (pi. 22, h). These trenches were cut dowm in 1-foot levels and the same methods were used as if the whole mound was to be removed. Profiles Profiles were taken along the base line, the Rl trench, the RIO trench, and as much of the L9 trench as was excavated. These profiles are shown in figures 6 and 7.

The base-line profile shows the relationship of the top soil, the black clay, and the light-colored clay hardpan. It also shows the position of shell where it was struck in two places near 0R2 and from 0L9 to 0L20. This latter exposure of shell seems to indicate that the mound's long axis is not parallel to the present course of the Ten- nessee River, but runs in a more east-west direction. It was found difficult to distinguish at every square the contact of black soil and hardpan, one grading into the other. The hardpan is not seen as a floor in several squares, but the black clay has the characteristic gradation, and it was not deemed advisable to excavate below the.
