 Nile overflowed its banks, we may reafon- 

 ably fuppofe, that all the large extent of 

 country called Lower Egypt, is now partly 

 filled up, by the fediment or flime leaving a 

 little every year ; fo that now the water will not 

 have the lame effect upon the fame ground, 

 that it had in thofe early periods of time.

 firft. 



Secondly, It is above twenty years fince I 

 advifed the embankment of the river Tay, at 

 the conflux of the Earn with it, upon the e- 

 flate of Eafter Rhind, and likewife propofed 

 to join the ifland in the Tay with the main-

 oats upon each .acre, the firft crop upon the 

 ifland.
