about 10 feet wide — that is, tliere is here neither ditch nor embankment 

 — this entrance faces and is about 40 feet away from the edge of the 

 terrace or bluff, which is here quite steep, and about 100 feet* (estima- 

 ted) hi^h above the river, whicli is here quite near the foot of the bluff. 

 The edge of the terrace and ridge coincide here." 



The ridge to the east of this work slopes genth^ until it reaches the 



general level of the plateau. On this slope numerous relics are found. 



The above described work was explored by Mr. Giauque and others, 



and several fine relics were found. The finding of one he describes as 



follows : 



" One of the trenches was begun about the north of the mound, and 

 the writer (Mr. Giauque), while working here, hardly a foot below the 

 surface of the mound, and about 7 feet from the centre of it, found a 

 very fine relic. It is a tube 6 inches long, a little less than an inch in 

 diameter, made of crinoidal limestone, highly polished, though some- 

 what coated and discolored in places by the oxide of iron which has 

 collected on it during its long burial. The hole extends entirelj'' 

 through from end to end, but grows rapidly smaller near one end, being 

 about f ths inch in diameter most of the distance, and about 3-16ths of an 

 inch at the smaller end. This relic is in fact a cjdinder for about A^ 

 inches of its length, to a diamond shaped perforation." 



I have measured the circumference of some of the larger trees grow- 

 ing on this work; an oak has 9| feet, beech 8^ feet in circumference on 

 the central tumulus, maple 6 3-10 feet, an oak 6 7-10 in circumference. 

 North west of this work, and about 200 feet distant, at the foot of the 

 sand ridge, and on the general level of the plateau, is a mound (Group 

 A, No 2), which has been recently explored. Its diameter east to west 

 is 45 feet, elevation 7 feet. An oak tree on its^western slope has 8 7-10 

 feet, and a beech on its eastern slope 5 feet of a circumference. An 

 interesting account of the exploration of this mound, by Mr. Giauque, 

 was published in the Harvest Home Ifagazine, in the article from which 

 I quoted above. The circumstances of the exploration are of considera- 

 ble interest to the archaeologist, and I make the following extracts 

 from Mr. Giauque's article: 



* * "About 11 feet from the outside, and 2 feet above the original 

 surface, the shovel hitlierto working pretty freely in clayey sand, 

 struck the first big stone. It was a flat limestone, possibl}' brought 

 from the neighboring hill, about half a mile awa}', as there were none 

 nearer, and it was much reddened and softened by fire, the fossil shells 

 in it being whitened, or more nearl}^ calcined than the other parts. 

 This, together with charcoal and ashes, pieces of bone, pieces of bowl-
