fragments of bone and teeth, and beneath them charcoal and flint 

 chips. In the other mound {b) at about 6 feet depth, a fragment 

 of sheet copper weighing 260 gr. It was 4^ inches long, 2 inches 

 wide, and about the thickness of ordinary tin. It was slightly 

 curved and found in the bottom of the mound lying in puddled 

 clay. This bottom was dish-shaped, rounding up at the edge, i 

 foot deep and 6 or 8 feet across. It lay below the original sur- 

 face. 



Gass 71 mentions a tablet found in a Toolesboro mound by 

 Mr. Potter ; it was taken from a depth of 1 3 feet where it lay on 

 a small pile of bones ; it is made of white sandstone, 2 feet by 3 

 feet, and 3 inches thick, is rounded at corners and bears some old 

 signs or pictures on one side; some English letters have been re-

Thomas '74 cites Wakefield as to mounds on sections ij and 

 24, Twp. 100 N., R. 4g W., and Fulton 59 speaks of mounds with 

 circular terraces, 15 to 20 feet in elevation, and of remains of re-

The former '^7 describes mounds and stone circles a mile be- 

 yond Brown's Station (La Valley) near the Little Sioux River 

 and close to the Dakota line. The mounds are mostly round, 30 

 to 50 feet in diameter, 3 to 8 feet high; a few are oval and larger. 

 On the summit of the ridge are stone circles or ellipses made with 

 some care with bowlders. Some mounds lie among the bowlder 

 circles but most are outside the circle-bearing area. The whole 

 ridge top is strewn with flint-flakes, arrow-heads, scrapers, pot- 

 sherds, etc. Good stone mauls are not uncommon. White and 

 Starr opened two mounds. No. i was of hard gravel with patches
