As the mud dries these
plants develop in great profusion, giving an appearance to the surface
as if covered thickly with brick dust.
These depressions and swaily places, holding water part of the year, and
becoming dry during the malarial season, can be easily dried by means
of covered drains, and grassed or sodded over, when they will cease to
grow; this vegetation and ague in such localities will disappear.
The malarial vegetations begin to develop moderately in July, but do not
spring forth abundantly enough to do much damage till about the middle
of August, when they in ague localities spring into existence in vast
multitudes, and continue to develop in great profusion till frost comes.
