Nov. I, 1755. 38 minutes pall 9 in the morning. 
T his moment happened an earth- 
quake, which lafted more than a 
minute (I believe near two) though of fo long a 
duration, I do not think it fo terrible as that in 1 748, 
poflibly owing to the prefent being in the day-time j 
but, I affure you, it Ihook every thing about me very 
cfFedually. 
P. S, Three quarters paft eleven j there is a cir- 
cumftance attends, or rather follows, the earth- 
quake, which is very furprifing, and, I confefs, 
ihocks me more than the thing itfelf, which is, 
the fea all bn a fudden rifes as though it were the 
main body of it, and in many parts runs quite to 
the wall, and at the prattick houfe, in at the 
gate. I fay, as though it were the main body, 
as there is no more fwell at other times, than in 
the midft of fummer, with a light eafterly breeze, 
and fuch as has blown all day. I was juft called 
on to obferve this, and thought proper to mention 
it. God, of his infinite mercy, preferve us from 
all difafters. 
November 3. Thank God we have had no return of 
the earthquake, nor was the rifing of the fea at-
