Il. The dry deciduous hill type is found on the outer 
slopes from 1.500 to 3,500 feet with a rainfall of from 20 to 60 
inches. The slopes are generally very rocky and precipitous. 
The characteristic species here are Cochlospermum Gossy- 
pium D.C., Shorea Talura Roxb., Sterculia urens Roxb., Eriolaena 
quinquelocularis Wight, Buettneria herbacea Roxb., Plectronia 
idyma Gaertn., Diospyros montana Roxb., Didymocarpus Rottle-

lil. The moist deciduous forest type, mainly situated in 
the western extremity, though it occurs also in patches here 
and there in favourable localities. It ranges between eleva- 
tions of 1,500 and 2,500 feet with a rainfall of from 50 to 100 
inches and merges into the evergreen type. This is the most 
important type in the estimation of the forest officer, for it is 
here that the finest timber trees are found and where they 
attain their greatest development. Here w 
stems of Tectona grandis Linn., Dalbergia latifolia Roxb., Ter-
