An account, which we have lately received from 
the Weft-Indies, agrees very well with the fuppoft- 
tion, that our earthquake proceeded fouth-eaftward. 
The account is, that ‘ on the 1 8th of November, 
‘ about two o’ clock in the afternoon, the fea with- 
* drew from the harbour of St. Martin’s, leaving the 
‘ veftels dry, and fifh on the banks, where there 
1 ufed to be three or four fathom water ; and con- 
e tinued out a .confiderable time ; fo that the people 
c retired to the high land, fearing the confequence 
e of its return ; and when it came in, it arofe fix 
c feet higher than ufual, fo as to overflow the low 
( lands. There was no ftiock felt at the above time/ 
As this extraordinary motion of the fea happened 
about after, our great ftiock, it feems very likely 
to have been occafioned by the fame convulfion of 
the earth. Now if this earthquake went off fouth- 
eaftward into the Atlantic, it muft have pafied con- 
ftderably to the eaftward of St. Martin’s ; and, in 
fadt, it did not reach that ifland, there being no 
ftiock felt there. The motion of the fea then was 
owing to a great agitation raifed at a confiderable 
diftance in fome part or other of the ocean, where 
the earthquake pafled, and from thence propagated 
to that ifland. Nor is the length of time greater 
than what feems to be neceflary for this effedt. The 
earthquake itfelf, at the rate it moved with us, would 
be fome hours in going from hence to the diftance 
of St. Martin’s : for found would be about 2^ in 
moving to fuch a diftance ; and the progrefs of the 
earthquake was flower than that of found, as appears 
from hence, that the roar of this earthquake arrived 
here near a minute before the fliake. The reft of
