Acres ; Roods. The Line 2. was a Hedge of large Affi 
and Willow Trees between the Meadow and the firm Land, 
4. Was the Edge of the Bog next to the Padure. The prickt 
Lines from 3. to and from 4 to 6. Ihew the Limits or 
Bounds of the Bog. 
2. The Meadow C was lower by a Defcent of 5- Foot 
than the Pafture and the Padure D was lower by 6 Foot 
than the Surface of the Bog : And there was yet a coiifidera- 
ble rifing and Hill, as at E, the Height whereof was above 
10 Foot above the Surface of the Bog; fb that there was a 
Defcent from E to the Meadow. 
Now I come to its Motion^ and will prefume to fhew 
the Caufe in Brief. A more than ordinary wet Spring occa- 
fion'd a prodigious fwelling of the Height of the Bog at 
and at length moiften*d the whole, but chiefly the under 
part thereof, the Water foaking to the Bottom. By this means 
the Turfy Hill E being as it were undermin'd, naturally funk 
down, and confequently prefs'd the Bog on all hands, chiefly 
towards the Defcent ; till the Pafture D was forced on the 
Meadow C, overturning the intermediate Hedge. So that the 
Line 3, 4. is now become i, 2. and the Meadow and the 
whole Bog are LeveljOniy there are Chafms and great Cracks 
throughout the whole Surface of the Bog, reprefented by the 
ftroaks about E. The Bog contains 40 Acres. 
Whereas fome conceive that this Motion cannot be Natu- 
rally explained, for Two Reafons ; Firft^ That no Quantity 
of Water was difcovered on the faid Motion. Secondly ^ That 
no confiderable Defcent appears now to the Spedators. As to 
the Firfi^ I know that there was a Quantity of Water. And 
as to the Latter^ 1 know alfb that there was a De(cent, as I 
havcdefcribedit. My Caufe cf Knowledge is, that I hold 
Farms from the faid BrookBridges ^^{q]ommg to,and bounding, 
with the faid Bog, and was acquainted with the fame before, 
the Motion.
