of 23 feet. At the eastern end and at the corners (which are rounded 

 oft) are strips of the original level 2 or 3 feet wide between the margin 

 and the ditch. The top is rounded. The surrounding wall and ditch 

 are interrupted only by the gateway at the east, which is about 30 

 feet wide. The ditch is 3 feet deep and varies in width from 20 to 

 23 feet. The wall averages 20 feet in breadth and is from 1 foot to 



3 feet high. Two 

 chestnut trees, one 

 6, the other 7 feet in 

 circumference, were 

 growing on the 

 mound. 



A partial explora- 

 tion of the mound 

 gave the following 

 results: The first 5 

 feet of the top was 

 found to consist of a 

 layer («, Fig. 309, B 

 and C) of yellow clay 

 similar to the sur- 

 face soil of the spur ; 

 the remainder (b) of 

 earth, which must 

 have been brought 

 from the valley be- 

 low. In this latter 

 could easily be 

 traced the individ- 

 ual loads or little 

 masses by which it 

 had been built up, 

 as in the case of the 

 cemetery mound at 

 Mount Vernon. At 

 the base, 30 feet from 

 the south margin, 

 was a bed of burnt

clay, on which were 

 coals and ashes. In the center, also at the base, were the remains of a 

 square wooden vault. The logs of which it was built were completely 

 decayed, but the molds and impressions were still very distinct, so that 

 they could be easily traced. This was about 10 feet square, and the 

 logs were of considerable size, most of them nearly or quite a foot in 

 diameter. At each corner had been placed a stout upright post, and 

 the bottom, judging by the slight remains found there, had been wholly
