upon ahoufe, andattended- with a great noife.. This fuddem and 
great fhock began: with: the fame 4zd of motion ; and was im- 
mediately fücceeded. by quick and violent concuflions, jerks and 
wrenches, attended. “ with an undulatory, waving motion of 
the whole furface of the ground, not, unlike. the. fhaking and 
quaking of a very large bogg." After this great fhock had 
been gradually declining and going off, near half a minute, there 
was.a fenfible revival of it, though of fhort continuance ; and 
fo all. by degrees became ftill and quiet again. 
he violence of this earthquake was the greateft of any we have 
ever had in the country. ‘ In Bojfon, befides the throwing 
down of glafs, pewter, and other movables in the houfes, about 
an hundred chimnies were, in a manner, levelled with the roofs 
of the houfes ; and about fifteen hundred fhattered, and thrown 
down in part. Some. were broken off feveral feet below the 
“top ; and by the fuddennefs and violence of the jerks, canted 
horizontally an inch or two over, fo as to ftand very dangerouf-

: points of the compafs, as with a circular motion. The roofs 
“of fome houfes were quite broken in by the fall of chimnies.

down, from the top to the eaves of the houfes. Many clocks 
. were ftopped. The vane upon the. public market-houfe was 
thrown down ;—the wooden {pindle, which fupported it, being 
broken off at a place where it was five inches in dicmeter, and: 
tén feet in height ; and which had ftood the moft violent gufts

ent at the fpindle, two or three points of the compafs :
