9. j4t Rochford in Essex. By the Rev. Mr. T/iomlinson. p. 364. 

 At a pond in a close of Mr. Sly's, adjoining to the church-yard, the water was 

 observed to flow a considerable way up the mouth of the pond, and then return- 

 ing, to flow up the opposite side, repeating this sort of motion for about a quarter 

 of an hour. The motion of the water in the pond was only from east to west, 

 and from west to east, alternately. 



10. In Berkshire, near Reading. By Mr. Rd. Philips, p. 365. 

 On the 1 St of November last, at about 1 1 o'clock in the morning, as Mr. 

 Pauncefort's gardener was standing by a fish pond in the garden, he felt a most 

 violent* trembling of the earth, directly under his feet, which lasted upwards of 50 

 seconds; immediately after which he observed that the water in the pond was in a 

 very unusual motion, and suddenly thrown on the opposite side, leaving that on 

 which he stood quite dry, for the space of 1 yards, and continued in that state 

 for about 1 minutes, when it returned as before, and collecting in or near the 

 middle of the pond, rose about 20 inches above the level of the water on each 

 side, and continued so for 2 minutes in violent agitation, which the gardener 

 described to be like the boiling of a pot. 



At the same time Capt. Clarke, at Caversham in Oxfordshire, a mile distant 

 from Reading, was alarmed with a very great noise, as if part of the house had 

 been falling down; on examination however it did not appear that the house was 

 at all damaged ; but a vine, which grew against it, was broken off, and 2 dwarf 

 trees, such as are used in espalier hedges, were split by the shock. 

 11. Near Reading in Berkshire. By the Rev. J. Blair, LL.D., F.R.S. p. 36/. 

 At Earley-court, near Reading in Berkshire, in a small fish pond near the 

 house of Edward Pauncefort, Esq. the water was observed, about 1 1 o'clock in 

 the forenoon, to be in a strong agitation, like that of the tide coming in. The 

 first motion of the water was from the south end of the pond to the north end, 

 leaving the ground or bottom of the fish pond on the south end without water, 

 for the space of 6 feet. It then returned, and flowed at the south end, so as to 

 rise 3 feet up the banks, and immediately went back again to the north, where 

 it likewise flowed 3 feet up the banks; and in the time between the flux and 

 reflux, the water swelled up in the middle of the pond like a ridge, or rising part 

 of the land. This motion or agitation of the water, from south to north, and 

 from north to south alternately, backwards and forwards, lasted about the space 

 of 4 minutes of time; and there seemed to be little or no motion in the direction 

 of east and west, the weather being perfectly calm during the whole time. 



* This is the only account that mentions any tremor of the earth to have accotnpanied the agita- 

 tion of the waters in this island j and the next account of the very same matter docs uot take I lie 

 least notice of any. — Orig.
