Towards the sea the solid land gives place to a vast network of streams and creeks, whose sluggish waters are constantly depositing silt, and forming morasses or quicksands.
It rises out of deep water; well-sheltered creeks indent the opposite shores on both sides.
These rivers approach each other at their mouths, and form a vast network of tidal channels, creeks and islands.
Although very little of the coast belt is actually swampy, a kind of natural canalization connects many of the rivers at their mouths with each other, though some of these connecting creeks are as yet unmarked on maps.
Towards the city the red soil is intersected by creeks and morasses, whose margins yield crops of rice, mustard and til seed; while to the east of the town, a broad, alluvial, well-cultivated plain reaches as far as the junction of the Dhaleswari and Lakshmia rivers.
