stones with some slated huts inside. ‘The’ place ‘of observation is a pillar 
built by Captain Hopeson within the fort, the position of which is shewn 
as well as the dimensions of the fort, in fig. 2, (Plate IV).. There is an 
outer wall, one corner of which is sufficiently high to be well defined: it 
has been sometimes observed, a flag staff being erected to mark the spot. 
This is also indicated in the figure. 
A. Surkanda is a high mountain on the border of Gerhwal, and the 
Din. ~The pyramid which forms the signal is similar to that at the Chur, 
and is erected over the centre of asmall temple with a pointed roof, which 
had been the point always observed previous to the erection of the signal. 
The place of observation is a stone pillar built close to a corner of this tem- 
ple: the direction and dimensions of the latter being all marked in fig. 3, 
(Plate IV). 
From the Chair as already noticed the station of Belville is not visible, 
and we were therefore compelled to use white lights.
