The Naga hills, to the eastward, probably exhibit a very 

 similar vegetation to the Khasia, as their elevation is about the

 at which season vegetation at considerable elevations is nearly 

 dormant. The greatest height attained by him was 5600 feet. 

 He describes these hills as much more covered with forest than 

 the Khasia,* and states that the southern slopes are moister 

 than those to the north. As the rain-fall must be much less 

 than it is on the southern slope of the Khasia,, the greater 

 amount of forest is probably caused by the diminished vio~
