tlie islaud that the group, consistiug of six luouuds and an eaitheu 

 wall, is lot-att'd. A plat of the group is given in PI. XLI. 



Starting from the bank of the bayou and moving northward we first 

 cross a strip of low laud several rods wide which borders the stream 

 and is subject to annual overflow.s. We then come to a low bluff some 

 8 to 12 feet high which forms the break or edge of the terrace or general 

 level, and which is undoubtedly the old bank of the Ohio. Ascending 

 this and moving north by tlie mouiul marked D and 

 turning our face to the east, we have a full and clear 

 view of the large luoimd (A) which is the prominent 

 feature of the group as shown in Fig. .'538, which rep- 

 resents the elevation as seen from the west. A plat 

 of it is given in Fig. 339. It is a Hat-topped mound, 

 oblong in fonu, capped at one end by a conical mound, 

 and furnished at the same end with an apron-like ex- 

 tension. The height at the northern end (A) is 27 feet, 

 but this increases as we approach the lower end (1 )) 

 to oO feet. The height of the apron varies from fi to 10 

 feet. The entire length of the base from north to south 

 is about 520 feet, the width varying from 130 to 150 feet. 

 The length of the top of the up])er level on the west side ? [20ft. 

 is 230 feet; of the apron, alxmt 150 feet. The width 

 of the top of the upper level varies from 93 to 110 feet. 



The conical portion at the southeast corner of the 

 main structure rises to the height of 20 feet above the 

 upper level, the circunrfereiice at this level being 290 

 feet, giving a diameter of 93 feet. This is, more cor- 

 rectly speaking, an addition to the original structure 

 and not simply a superimposed mound, for the slopi- 

 on the southeast portion extends down to the original 

 surface of the ground and Ijeyond the base of the 

 main structui'e. This feature, though rare, has been 

 observed in some two or three other cases, as, for ex- 

 ample, in one of the mounds of the Seip works, in 

 Ross county, Ohio, and one of the Linn mounds. Union 

 county, Illinois. 



The structure marked B, PI. xli, is a low, conical 

 mound about 100 feet in diameter, much worn by the 

 plow, so that at present it is only some 3 or i feet high. 

 N. 540 E. of A (measuring fiom the point d on the top of the latter). 

 Near by is a small excavation from which part of the earth used in 

 building the mound was probably taken. The surface of the ground 

 between these two mounds is strewn with fragments of jjottery, broken 

 mussel-shells, flint chips, etc. 



Mound C is situated 650 feet N. 80° W. of the large mound. It is a 

 low, conical tumulus, the north and south diameter being 102 feet, and

It is 665 feet
