northwest. This area, however, was overtiuwed in the great rise of 1844, 

 and also in 1SS2, tlie hirge mound hereafter described being the only 

 part not under water. A creek ruus along the east and northeast, sep- 

 arating the area from the blufl'. The soil is a rich deep alluvium, under- 

 laid by sand, with neither rock nor gravel in place. 

 Eeferring to the annexed plat (Fig. 82) made by Prof. Hull from a 





careful survey taken by him during our visit, we see that a wall, start- 

 ing on the west side of the creek at the east end of the inclosurc, runs 

 thence southward to the beud, a distance of 400 feet, where it curves 

 southwestward 126 feet. From this point it runs almost directly west 

 to the corner 1,108 feet; thence north l,0;i(> feet to the northwest cor- 

 ner, thence east to the bank of the creek 50!) feet, embracing in these 

 boundaries about 28 acres.
