These floods reached the following levels at this 
point on the river. 
1893 . . About 38 feet above low water. 
If the last small flood has caused such a high mor- 
tality among the Grey Mangroves those floods of 1893 
and 1898 would cause a much greater number of fatal- 
ities. There is abundant evidence here that the 1893 
flood deposited enormous quantities of silt along portions 
of the river which well may have wiped out the man- 
groves altogether at that time.
