two northernmost gables are of 15th century work and originally 
formed a portion of a Convent connected with some foreign 
community. Before leaving the Churchyard on the N. a sycamore 
tree, said to be the finest in Wiltshire, was noted and attention 
called to the Chancel buttresses, evidently original Decorated work. 
The Chancel walls have been raised, and here again thie circles 
afforded the quarry whence materials have beenused for this 
purpose. The points of interest connected with the Church being 
now exhausted the Vicar lead the way to the two upright stones, 
remnants of Stukeley’s Adytum or cove of the N. circle. The 
remains of the third stone, destroyed in 1713, Mr. King said he 
had seen, consisting of chips mixed up with burnt straw and 
faggots, showing the means used for its destruction. The taller of 
the two now standing, he said, measured eighteen feet out of the 
ground and was the highest of all the stones ; it was probably sunk 
some three feet into the solid chalk and kept in an upright position 
by blocks of ‘Sarsen stones’ jammed in at the base, as was probably 
the method with all the other stones. The members thanked Mr. 
King fer his kindness and valuable information, visited the 
remains of the southern circle and left the Vallum, which 
unlike most other military works has the ditch on the inner side, 
by the Kennet Road; there was a sufficient number of stones 
remaining here to convince even the most sceptical that they once 
formed an Avenue. 
An instance of local pronunciation may be worth recording ; 
an old man returning to his midday dinner from the fields, 
divining our object, told us that we should find many more 
old stones on the road, and that the name of the hill inter- 
vening between us and Silbury was ‘“ Weedon ;” Stukeley’s 
Weedon, and the Waden hill of the Ordnance Maps. After 
tracing the stones on either hand and crossing the Kennet stream, 
a traverse was made to the long barrow on the top of the hill 
immediately south of Silbury ; here the first halt of the day was 
made. Seated on one of the many ‘Sarsen stones’ now lying
