wind ; and took notice, that three ducks, which 
were then in the weftern pond, immediately flew 
out of it into the other, as if they were affrighted. 
At the fame inftant the water in the weftern pond 
arofe at the head of it, fo as to run out of the lower 
drain, which was ten or twelve inches above the 
level. He did not fee this fwell of the water him- 
felf ; but his fervants, who faw it, called him im- 
mediately;- and he found, that the water was then 
in motion ; and that it had run out of the drain. 
It continued to move backwards and forwards for 
fome time ; but he obferved, that it did not fwell 
any more at the head, but only arofe and fell by 
turns at the two mouths ; fo that the motion was 
then from north to fouth. When it arofe at either 
of the mouths, it flowed about fix feet beyond what 
was then the water-mark. The other pond, during 
the whole time, was as calm and ftill, as he ever faw 
it ; nor had his fervants obferved any motion in it,

ducks. 
Mr. Mott tells me farther, that Wickham-hall, 
which is another farm, about two miles and a half 
from him, in the parifh of Bifhop-Stortford, in the 
fame county, a pond was moved at the fame time in 
the fame manner; and that the firft motion of it 
was from eaft to weft. This account he had from 
a perfon, who faw it. He adds, that a like motion 
was obferved in a pond at Thaxted, in the county 
of Eflex : but of this he knows no particulars. 
At Royfton, in the county of Hertford, Mr. 
Newbell, an officer of the excife, obferved an un- 
ufual motion in the pond, at ten o’clock in the fore-
