Louisa County — Continued. 



mately i)arallel to the edge of the bluff; the mounds al)out here 

 are arranged in several somewhat irregular rows, all running the 

 same way. This mound is 15 feet in diameter, and i^ feet high; 

 it was of mixed earth to a depth of 3 feet, where was natural 

 yellow clay; at bottom were parts of a badly decayed human 

 skeleton and some splinters of flint. 



No. J. Close to bluff-edge in first row, at fifty yards south of 

 No. I, 20 feet in diameter; 2 feet high; at 2 feet from top was 

 an excavation into the natural soil, i^ feet in diameter and 2 

 feet deep, full of ashes and charcoal. 



No. 4. Fifty yards south of No. ^ ; with a diameter of 25 feet, 

 it has a height of 3 feet. It consisted of mixed soil for 3 feet, and 

 then of a hard layer of white clay eight inches thick. 



No. 5. Ten yards west of No. 4, and in the second row; it 

 is 25 feet in diameter and 3^^ feet high; it consisted for 2^/^ feet 

 of mixed soil resting on white clay 11 to 15 inches thick; below 

 this but to one side of the middle was a small quantity of ashes and 

 charcoal; in the centre at 2 feet or so down was a sitting skele- 

 ton; no relics. 



No. 6. At nine yards north from No.^, in the second row; 

 it measured 20 feet in diameter and z^z feet high; it consisted of 

 a mixture of common soil resting on hard natural clay; a few- 

 fragments of decayed bones were found, but no relics. 



Numl)ers 4 to 6 are on Stoddard's farm. The rest of this 

 series are probably on Haas' farm. 



No. 7. Sixty rods north from last, on the second row; 15 

 feet in diameter; 1)2 feet high; composed of soil like No. 6. 



No bone fragments and no relics. Gass ^3 speaks of eight 



mounds in this quarter-section, and enumerates as relics from 

 them a plain red pipestone pipe, a few shell beads, an obsidian 

 arrow-head, a number of flint implements. 



At BlackJiawk, opposite Mercer County, Illinois, near the 

 Mississippi River, on a high bluff facing New Boston, are seven 

 or eight mounds, the largest in this part of the West. They are 

 4 to 5 rods in diameter, and 12 to 15 feet high; one yielded 

 numerous partly decayed bones, also pottery, flint implements, 

 and flint clippings. On the high level plain back of the mounds 

 was an old embankment enclosing some 5 or 6 acres; it is now
