At 3" 12 m it rose again to the same height as at 3 h 3 m ; receded

 and returned rapidly. 



At 3 h 36 ra , was as high as at first and second times ; fell two feet. 



At 3 h 42 m , nearly the same height as at third rising ; it then sunk

At 3 h 50 m , several feet below low-water mark; spring tide rushed in 

 again. 



At 3 h 54 m , rose full two feet higher than at the third time; fell

At 4 h , was down at high-water mark, neap tide. 



At 4 h 15 m , rose about half as high as at last time. 



At 4 h 20™, was down to low-water mark.

At 5 h 3™, again at low-water mark. 



At 5 h 8 m , rose again about one foot above high-water mark, spring 

 tide ; after which it gradually sunk to low-water mark, and during 

 the remainder of the evening continued to ebb and flow less fre- 

 quently than during the afternoon, and not passing the bounds of 

 high and low water. 



During the evening preceding the above remarkable event, we had 

 frequent and heavy squalls from the east, which continued till 7 

 a. m., from which time the day was calm and cloudy, and frequent 

 light showers, but no heavy rains till the one referred to above, at 

 4 h 40'", after which it continued to rain more or less till ten o'clock. 



On Thursday, the 8th, the tide continued to ebb and flow in an 

 irregular manner, both as to time and height, being sometimes a little 

 below low-water mark, and a little above high-water mark, and at 

 other times ebbing and flowing the same as at neap tide till 4 p. m., 

 when it rose to the same height as at the first time the day before ; 

 fell about half tide, and for a short time appeared nearly stationary.
