District, I have marked in on a map of the district the limits of 
e “ Khadir,” 
I may say that in some places the limit of the “ Khadir” is 
exceedingly plain, whereas in other places it is not at all so plain 
to the eye.

south just west of Birpur; but the western edge is very ill- 
defined, 
imi hence 
imity to the west of the boundary of a large sandy tract w 
considerable amount of material has probably been blows i 
the strong west winds which prevail during the early part of the 
hot weather. 
The fact that these concave bends, which form the limits of 
the “Khadir,” are n

Indicated by the indentations in the edge of the “ Khadir,” a very

though the vagaries of the Ganges are proverbial, 
be borne in mind that, whenever the river impinges on the old 
alluvium, the process of denudation is very slow i ie

(without any kunkar reefs to protect it), which is ee ai

later, does not exceed ten feet in the year.
