The Prehistoric 3Ionuments of the Little Miami Valley. 127 



300 feet in length, and 100 feet in width, with a gradual descent to the 

 alluvial bottom at its base. 



The material of its construction is evidently a portion of the earth 

 excaA^ated from the ditches. Its eas,y asceut and breadth would induce 

 the belief that it was formed to facilitate the entrance of some ponder- 

 ous vehicle or machines into the fort. To defend this entrance thev 

 raised a mound of earth seven feet high, forty wide and seventy-five 

 long. It is placed about 100 feet from the mouth of the causeway-, and 

 is so situated that its garrison could sweep it to its base. The whole 

 area of the fort, the wall and causewa}', are covered with large forest 

 trees, but there is not a tree growing in either of the ditches, and there 

 are but a few low underbrush on their side. 



At present the circular wall is almost leveled, but can be readilv 

 traced b}' the color of the soil, and the large number of flat river stones. 

 The ditches can be easily recognized. The mound is still prominent. 

 It measures now, height 5^ feet, diameter 25 j-ards, circumference 

 75 3^ards. The causeway is cut through by the C. & E. R. R., the for- 

 est cut away, and the soil cultivated annually. 



No. 2 of this Gi'oup is a large, circular embankment, with a diameter 

 of about 125 j-ards. The material forming the embankment is evident- 

 ly taken from within the enclosure. This work is a |)erfect circle, with 

 an opening or gateway thirty feet wide to the south. It is about 300 

 yards distant from the first work of this Group. Two hundred j^ards to 

 the south of this circle are two mounds, No. 4 on chart being the larger. 

 It has a circumference at base of 250 feet, and an elevation of twelve feet. 

 One hundred and fifty 3'ards east of these mounds is another of very 

 regular shape (Group D, No. 5, on chart); height, four feet, circum- 

 ference, 150 feet. No. 6 of this Group is a small mound, situated in 

 Section 22, Columbia township, on an elevated ridge known as Grave- 

 lotte, on the estate of T. R. Biggs. It is situated in a corner of a large 

 embankment. Its height is 3 feet, circumference 150 feet. No. 7 of 

 this group is located in section 29, Columbia township, ^ofa mile west 

 of Camden, just south of the Wooster turnpike. It is now only one 

 third its former size, it being partly removed in the construction of 

 the Wooster turnpike. Its present dimensions are, height nine feet, 

 diameter seventy feet. In the southeast corner of Section 29. at the vill- 

 age of Camden, and 300 feet east of the south line of Mr. Galloway's resi- 

 dence, is the corner of an embankment which extends east and south to 

 the river. It extends fths of a mile east, until it reaches the bank of the 

 river, which is here about 40 feet high, the other running south until it 

 reaches the edge of the gravel ridge, and then runs east to the river. 

 It incloses from 800 to 1000 acres of ground. This embankment, 50 years 

 ago, was six feet high and twelve feet wide. It is now scarcelv trace-
