which water stood in those shafts, at the end of the long dry season, 

 before the rains commenced. 



Shaft No. 1. — 19ffc. to 20ft. deep. White alluvial clay with a 

 i large admixture of chalk rollings. In this shaft stags' horns were 

 found, and in no other. At the bottom the chalk rock showed 

 traces of the original workers, the chalk being notched into steps, 

 about a foot difference in level. The same kind of marks was found 

 in shaft No. 8. 



Shaft No. 2. — 2 lift. deep. White alluvial clay containing much 

 chalk rubble, also some sarsen stones lOin. to I4in. diameter. In 

 this shaft, at 6ft. under the surface, was found a brass coin of 

 Marcus Aurelius. Water rose in this shaft 8ft. deep. 



No. 3.— Sift, only ! 



No. 4. — 4ft. only ! 



A projecting mass of chalk for some reason has not been removed 

 at this point. Was this left as a sloping access to the hill, for 

 carrying the material during the erection ? 



No. 5— 15ift. This was the first shaft sunk The first 3ft. to 

 4ft. under the soil was white alluvial clay, then clay with a mixture 

 of chalk rubble. At 9ft. under the surface a distinct black layer, 

 about 1ft. thick, containing fractured flints, bones, burnt sarsen 

 stones, and charcoal. Then, below this layer, 5ft. of alluvial clay 

 j and chalk rubble to the bottom. 



Shaft No. 6.— 15ft. deep. This shaft, after the surface soil, 

 passed only through a fine tenacious white clay, containing no 

 chalk rubble. A few flints, flakes and broken flints, and some 

 bones, were scattered through this clay. The bottom 9in. contained 

 a large quantity of flint fragments. The absence of chalk rollings 

 or rubble may be attributed to the great distance of this shaft from 

 Silbury Hill. The white fine clay, when analysed, was found to 

 consist of chalk 88^%, insoluble silica Hi%. 



No. 7. Sunk at the extreme west limit of the meadow, was 



only 6ft. deep. White alluvial clay and chalk rubble. No bones 

 were found in this shaft. 



No. 8. 16ft. deep. Upper half tenacious discoloured clay, not 



pure white; lower half white clay, containing some chalk rollings.
