I Went a few Days ago to the Fuller $.Larth Pits at 
Wavendon near Woburn^ where there are feveral 
Pits now open •, but, as Men were then at work only 
in one, and 1 underftood the Earth was difpofed in 
much the fame Manner in all, I did not trouble my 
felf tO'go down into more than that wherein they were 
then dkging^ in which I found Things difpos’d thus. 
Frwii the Surface, for about fix Yards Depth, there 
are feveral Layers of Sands, all reddifli, but fome 
lighter colour’d than oti^^r^, under which there is a 
thin Stratum of red SaniSft^^, which they break 
through j and then for the Depth' b'f about feven or 
eight Yards more, you have Sand again, and after 
that come to the Lul/ers-Earth ^ the upper Layer of 
which, being about a Foot deep, they call the Cledge\ 
and this is by the Diggers thrown by as ufelefs, by 
reafon of its top great Mixture with the neighbouring 
Sand, which covers, and has infinuated itfelf among 
it : After which they dig up Earth for Ufe, to the 
Depth of about eight Feet more, the Matter whereof 
is diftinguifli’d into feveral Layers, there being com- 
monly about a Foot and an half between one horizon-
