portion, at the southeast and northwest. There are several breaks in 

 it at i^oints where it is crossed by little ravines, some of which may 

 have been formed since it was constructed. At /' a large piece of the 

 rock across which it ran has moved out and downward several feet, and 

 the break was repaired by filling in with stones; at c-d it passes 

 below the margin of the bluff and over a considerable space of the 

 descent. Why this was done, when it would have been as easily car- 

 ried around the top, is a question difficult to answer. At e it crosses 

 directly over a large bowlder. It is probable there was a gateway 

 somewhere on the level area at the east, but the wall has been so much 

 disturbed in this portion that it is impossible to decide this point now. 



There is a well-marked gateway at the southeast corner (g). At the 

 corner northwest of the mound the wall is much lower than on the 

 adjacent sides. This was in'obably a crossing iilace on the way to the 

 spring at the foot of the hill, though the descent for the first few feet 

 is somewhat I'ough ; yet we passed up at this point without much diffi- 

 culty. The entire length of the wall, following all the curves and bends, 

 is 6,010 feet, and the area embraced about 26 acres. 



lu the' western portion is a stone mound slightly over 100 feet in diam- 

 eter and 12 feet high. The section {a b) shown at the left passes through

 been gathered ft-om the area witTiin the inclosure and above the rocky 

 margins of the bluffs. The inclosed area has been under cultivation 

 for a number of years. 



ROSS COUNTY. 

 THE CRYDER MOUND. 



This is situated on the SE. i of Sec. 1, T. 10, E. 20, on the farm of 

 Mr. Frank Cryder, near Adelphi. It stands on a spur 60 feet above 

 the level of the valley, is of the ordinary conical form, 32 feet in diam- 

 eter and 2J feet high, though much worn down by the jjIow. Mr. Cry- 

 der says it was formerly surrounded by a ditch, but without the corre- 

 sponding wall like that in the Davis works. It was composed entirely, 

 of the red clay of the surrounding soil. 



Previous to its erection, a circular basin-shaped excavation (c, Fig. 

 320) was made in the original soil, 13 feet in diameter and 2 feet deeji 

 In this were the remains of five charred skeletons (1, 2, 3,4, and 5) with 

 coals and ashes about them. The skeletons (the flesh having been
