 arrow-heads and some flint chips. 



In this Summary we aim at definiteness. Many articles upon Iowa 

 Archaeology are so vague as to have no value. The arrangement of 

 material is, for convenience, in the alphabetical order of County names. 



Adams County. 



Thomas '74 lists a mound on the Thompson farm, near Corrmig. 



Allamakee County. 



Thomas '^s- '73, 174 describes works seven miles above New 

 Albin, on the Upper Iowa River. They are located upon a bluff, 

 lying in a bend of the stream, and bordering a bayou — no doubt 

 an old river channel. The top of the bluff is roughly rectangu- 

 lar. The northernmost, largest structure is an enclosure quite 

 exactly circular, except on the east, where it conforms to the line 

 of the bluff. At the southeast the ends overlap somewhat, leaving 

 an entrance-way between them. A ditch within borders the em- 

 bankment from the entrance on the south to the point where the 

 circular part is broken by the bluff-line. The dimensions of the 

 earthwork are — diameter from N. to S. outside to outside, 277 feet; 

 diameter, E. to W. outside measures, 235 feet; circumference, 807 

 feet; part along the bluff, 100 feet; entrance overlap, 45 feet; the 

 wall is quite uniform, with a height of about 4 feet and a width of 

 25 to 28 feet; the entrance is 16 feet wide; the ditch is 5 to 6 feet 

 wide and 3 feet deep. At the north an excavation adjoins the wall; 

 it is about 100 feet long, 35 feet wide at widest part, and 3 feet deep.
