Secondly, Below that is Fenny or Marfliy Ground, full 
of Reeds, which continues till they come to the Depth 
of Twenty Eight Feet ; where they Thirdly, Meet with 
a Bed of Clay Eleven Feet deep. Then Fourthly, ap- 
pears a Marlhy Ground, not unlike the former, and 
Fifthly, a Bed of Clay, but not fo thick as the former. 
SiiKthly, a Bed of Marlhy Ground. Seventhly, A Bed 
of Clay and Sand , mixt with Sea Produfts , this 
laft Bed they pierce with an Auger, upon the pulling 
up of which, the Water flows up with fo great Violence, 
that it cafts up Sand and Pebbles that fometimes weigh 
Four or Five Ounces. 
Before they bore this laft Bed,they hear a remarkable 
Murmur and Noife, which upon the Authors ftamping 
on the Ground with his Foot, did encreafe to that De-

Ears, ordered himfdf quickly to be pulFd up. 
Upon the Firft rifing of the Water in one of thefe

for carrying Veflels in which they go to Venite. 
Chap, II. He fays, that thefe Waters are running Wa- 
ters, which he proves by the Noife they make before 
their boring, and by their fud en rifiog after the Auger 
is drawn our, nor can this be occafion'd by the Preflure 
of the Ground fqueezlng up the ?^^a^er at the open Hole^ 
for fb the Ground would fall into the Placeof the Water

them from a Ciflern in the Appeoine Mountains, that 
runs through a of Sand lying under the laft Bed of Clay, 
which the Author in this and the Fifth Chapter il-

Opinion highly probable. 
Chap, liL He proves, that this Source cannot be from
