MOUNDS ON THE JACKSON PLACE, West CARROLL PARISH. 
Forming part of the great chain of mounds that begins with the one just 
described at Lower Jackson Landing and extends several miles up along the river 
to within sight of the town of Floyd, is a group of mounds on the Jackson Place, 
from which, unless obscured by trees, the great mound at Poverty Point is 
visible. 
On the Jackson Place, on property belonging to Mr. George W. Mont- 
gomery, of Tallulah, La., all in sight from the river bank, is this interesting group 
of six mounds, excluding various humps and small rises which are fairly numerous 
on the place. These mounds, to which letters have been assigned for clearness 
in description, all of which have been quadrangular with summit-plateaus, in 
some instances have suffered from wash and from a too close proximity of roads. 
Their relative positions may be seen on the plan (Fig. 28). 
Mound А, the southernmost of the group, has upon it the house of the man- 
ager of the plantation. "The height of this mound is 13.5 feet; the diameters of 
base are 177 feet N. and S. and 207 feet E. and W. Those of the summit- 
plateau respectively in the same directions are 96 feet and 135 feet. 
Mound B, 15 feet in height, has been about square, save that a ridge, now 
in the main eut away by a road, has extended from the eastern side. The di- 
ameter of base is 122 feet; that of the summit-plateau, 50 feet. 
Mound C, 9 feet high, has been in part cut away by a road on one side and 
eaten into by water on the opposite side. The basal diameter remaining intact 
is 82 feet, and that of the summit-plateau 26 feet. 
Mound D, having an altitude of 14 feet, has basal diameters of 155 feet 
N. and S., and 138 feet E. and W. The summit-plateau, which is about square, 
is 65 feet across. Probably the mound was square also at one time, but the sides 
have suffered extension through wash of rain. 
Mound Е, 9 feet high, has diameters of base of 78 feet №. and S., and 69 
feet E. and W. The diameters of the summit-plateau, in the same directions 
respectively, are 33 and 27 feet. 
Mound F, which has a house upon it, has been plowed out of shape by 
continued cultivation and has suffered by wear and by wash. A representative 
diameter probably would be about 190 feet, 150 feet of which would be beneath 
the summit-plateau. The height is 6.5 feet. Long ridges extend from this 
mound, one toward the north, the other toward the south. 
The usual ponds, caused by the removal of material for the mounds, are 
present at this place. | 
No digging was done in the mounds on which houses stood. All others, 
with these exceptions, were investigated, but not in as complete a way as would 
have been possible had the mounds been in a territory where their complete
