When the firft Tree funk, it was obferved, that the 
Water boyfd up in the Hole; but upon the finking of 
the greater Pit, that Water drain’d off into it, from the 
former, which now continues dry. The depth thereof 
to the firm Bottom is nine Foot three Inches ; and the 
Tree that Bands upright in it, is 5 Foot 8 Inches in 
Girt, and its Trunk about 18 Foot long, half of which 
is now within the Pit. In the Bottom of the greater 
Pit, there is a Pool of Water about 8 Foot Diameter ; 
whofe Surface is ii Foot 3 Inches below the Ground, 
and the Trees that are in this Pir, are much of the (ame 
length with the other, but fomevvhat fmaller, the one 
being in Girt 3 Foot j Inches, the other but two Foot

The Soil on which thefe Trees grew, is Gravelly; 
bat the Bottom is a Quick fand over a Clay, upon 
which there are Springs, which feed large Ponds ad- 
joyning ioSkCharUs Potts’s Houle, at about a quarter of 
a Mile from thefe Holes. , 
The Nature of the Soilfeems to afford us a reafonable 
conjedure at the Caufe of this odd accident, which 
Tome perhaps may be apt to reckon as a Prodigy. The 
Springs running over the Clay at the bottom of a 
Bed of very minute Sand, fuch as your Quickfands 
ufually are, may reafonably be fuppofed in many Ages 
to have walht away the Sand, and to have thereby ex- 
cavated a kind of Subterraneous Lake, over which 
thefe Trees grew: And the force of the Winds, on their 
Leaves and Branches, agitating their Roots, may well 
have loofened the Sand under them, and occafioned it 
to fall in, more frequently than elfewhere ; whereby in 
length of time the thin Bed of Gravel being only lefc> 
it might become unable to fupport its own w'eight and
