Oct. 29, 1727, about 40 minutes past 10 in the evening, there was heard a 

 great rumbling noise ; and before that, the bricks on the hearth rose up about 

 three quarters of a foot, and seemed to fall down and roll the other way, which 

 was in half a minute attended with the said noise or burst. The tops of the 

 chimneys and stone-fences were thrown down ; and in some places the earth 

 opened, and threw out some hundred loads of earth, of a different colour from 

 that near the surface, something darker than the white marl in England ; and 

 in many places, opened dry land into good springs, which remain to this day ; 

 and dried up springs, which never came again. It continued roaring, bursting, 

 and shocking our houses all that night. Though the first was much the loudest 

 and most terrible, yet 8 more, that came that night, were loud, and roared like 

 a cannon at a distance. It continued roaring and bursting 12 times in a day and 

 night, till Thursday in the said week, and then was not so frequent ; but on 

 Friday in the evening, and about midnight, and about break of day on Satur- 

 day, 3 very loud roarings : we had the roaring noise on Saturday, Sunday, 

 Monday, about 10 in the morning, though much abated in the noise. 



Nov. 7, about 11, it roared very loud, and gave our houses a great shock; 

 and continued shocking from 3 times to 6 every day and night, till the 12th of 

 November, when it was heard twice in one hour in the afternoon. 



Nov. 13, two hours before day-break, the roaring was loud, and shook the 

 houses ; and so for several days after. 



January 3, 1727-8, about 9 at night, an easy shock. 



January 6, there were 5 shocks, attended with the roaring. 



January 24, it roared exceedingly loud. 



January 28, 2g, 30, several more shocks, with the roaring. 



February 21, 29, the same. 



March 17, 19, also the same. 



April 28, 1728, a small noise. 



May 12, a long and loud roaring, that shook the houses. 



May 17, 22, 24, several more shocks. ->
