in cultivation for several years, but the mounds are still quite distinct. 

 The eastern face of the bluff is almost perpendicular. Between the 

 bluff and river is low, marshy ground, but the river bends in to the 

 bluff a little farther up. Mound 4 is in the timber, but tillable land, 

 springs, and the river are near. 



LYON MOUNDS. 



Up Sugar Creek, about a mile from its junction with the Sangamon 

 River, are two mounds. They are situated on the east bank of Sugar 

 Creek, on a bluff 30 or 40 feet high, on the SE. £ of the WW. £ Sec. 28, 

 in Clear Lake Township. The following sketch will give some idea of 

 their situation:

Mound 1 is 50 feet long, north and south, and 30 feet wide ; mound 

 2 is 70 feet long, east and west, and 50 feet wide ; they are each 16 or 

 18 inches high, and are 180 feet apart. No exploration was made. 

 The timber has been removed from the laud, but the ground has not 

 yet been explored. The builders of these mounds found in their vicin-

FARR MOUNDS. 



On the north bluff of Sugar Creek, about 2 miles above its junction 

 with Sangamon River, on the NE. ^ of the NE. \ Sec. 29, in Clear

 (Fig. 7) shows the manner of grouping : 



Mound 1 is 80 feet, and mound 2 is 100 feet long ; they are each 40 feet 

 wide and 2 feet high. Mound 5 differs from other mounds in that a pro- 

 jecting arm from the northwest side connects it with a smaller mound. 

 All the other members of the group are round, and range in diameter 

 from 20 to 50 feet, and in height from 10 inches to 2 feet. Mounds 1
