Discoveries at Waddon, Surrey. 41 
discovered in each chamber, at a depth of about fifteen feet below 
the surface of the ground. It was also found that the chambers 
were of beehive shape, about seven feet in height, and varying 
from twelve feet to something less in diameter. The regular 
form of the chambers is remarkable. It was probably produced, 
after the chamber was roughly shaped, by the excavator standing 
in the centre of the floor and scraping the sides and roof with a 
wooden tool.

Once made in this way, there would be little fear of the roof 
falling in, because the sand, owing partly to its having been de- 
posited in water, and partly to the slight proportion of clay it 
contains, is remarkably hard and firm. This particular quality 
of the Thanet beds, well known to modern geologists, was 
doubtless known also to the men who excavated the Waddon 
chambers. 
Each of the three chambers had its independent oval-shaped 
opening on the 8.8.E. side, but it is clear there was no other 
means of access to them until the crowns of their dome-shaped 
roofs were cut into in constructing the modern sewer-trench. 
This trench was fortunately made in such a way as to expose 
these three chambers without seriously damaging them, and it
