Part III. J Witt: Sylviculture of Hardwicicia binata. 
In Central India the tree is found in Chanda, parts of Berar, 
Khandesh, Nimar, Hoshangahad, and Indore State as far north as 
Mhow. The strangely local nature of the distribution of this species 
is but one of its many interesting peculiarities, and much local know- 
ledge will have to be gathered together and put on record, before a 
satisfactory explanation is forthcoming. Soil and climate — usually 
the most powerful factors in determining the limits of a species — 
do not supply in this case the solution to the question, though the 
former affects the quality of the growth to a very great extent. 
No better evidence could be adduced than a study of the distri- 
bution of the An jam in the Nimar District of the Central Provinces, 
with which the writer has had four years’ experience. We pro- 
pose to deal with the point at some length, since a just apprecia- 
tion of this phenomenon is necessary in considering the other sylvi- 
cultural peculiarities of the species, and any theories for the success- 
ful treatment of it, whether these theories be based on ascertained 
facts or on mere deductions from general observations. 
In order to draw attention to this peculiarity of the Anjan, it is 
necessary in the first place to describe the physical features and the 
geology of the Nimar District. 
(2) Physical Features of the Nimar District. 
Almost through the centre of the district, from west to east, runs a 
branch of the Satpuras forming the watershed between the N erbudda 
river on the north and the Taptee on the south. Practically the 
whole of this ridge is Government reserved forest. Between this 
range of hills and the Nerbudda river lies the town of Khandwa in a 
broad and fertile valley. The drainage from the central ridge to the 
north is diverted from its direct course by another low and irregular 
ridge constituting the forests of the Khandwa Itange. This parti- 
cular block will be alluded to again later on. North of this ridge, 
and bordering the Nerbudda river, is a strip of broken and hilly 
ground, from 3 to G mi^es wide, constituting the forests of the Punasa 
Kange. On the north bank of the river, and to the east is situated 
the Chandgarh Range, on the continuation of the hills constituting 
the Punasa Range. 
Along the southern face of the main central branch of the Sat- 
puras runs the Taptee. South of this river rises a higher ridge.
