About x. there are Chafms or Gapings full of Water, 
which make a Rill down the Hiatus B. E , J. but in no 
greater quantity than might have been expected from a 
Well funk to a lefs Depth. Though I was told that 
there were Holes in the higher Mountains, that received 
Water under Ground; yet I can find no fuch Thing, 
nor any Symptoms of a Current under Ground, either 
where it enters or riles, in all the Neighbouring Ground 
for fome Miles. 
It feems to me that there has been no Vacuity under 
Ground to receive the fubfiding Earth 5 for what the 
Bank E.L.F. is raifed higher, and what is tumbled down 
to the Plain a. b. may very well compenfate theSubfiding

But I forgot to mention, that before the Rupture the 
Declivity from X. to L. was not altogether uniform, but 
was Holiower where x. is now, than the adjacent Parts: 
It might have been, by the defcription I have from the 
People, 10 Feet deep in the Middle, and 100 Feet Dia-

don’t find the lead appearance of any. 
They impute it to the great and conftant Rains we 
have had hft HafVeft and Winter, which have foak’d 
and fteepM all the Ground, but cannot guefs after what 
manner they fhould produce this Effect^ for it is im- 
poffible any Water fhould Band on the Ground, or 
in the Vicinity, it being all on the Declivity of the 
Hill.
