year 1772 the Raja appeared before Captain Camar, commanding 
a force in Palamow, and after exchange of turbans acknowledged 
himself as a vassal of the Company. 
“Tn regard to this exchange of turbans,” writes Colonel Dalton, “ the 
family annals tell a strange tale. In the Raja’s turban were some very 
valuable diamonds, which it is insinuated had excited the cupidity of 
Captain Camar. The proposal for the exchange emanated, it is said, 
from him. He declared it was the English method of swearing eternal 
friendship, but the Captain had no diamonds in his head-dress, and the 
Raja evidently concluded that he had been rather ‘done’ by the Com- 
pany’s officer.” 
In Gangpur the Icha river, which is a tributary of the Ebe, 
is marked on the Topographical Survey Map as being the site 
of diamond washings, but on what authority I know not. I 
have, however, myself heard the Ebe, near its sources, spoken of 
as the Hira (diamond) river. 
Geology.—The geology of the localities on the Sunk and Icha 
rivers isnot yet known. Possibly it may be found that there are 
outliers of the [Mahanadi-Godaveri] Vindhyan formation in their 
vicinity. 
BANDELKHAND. 
The writers who have described the diamonds and diamond 
mines of Bandelkhand, from personal observation are many,* 
besides them there are also not a few { who have written on the 
subject without having had the advantage of visiting the spot. 
Franklin and Jacquemont, give ample details of the mode of 
working and extraction of the gems, their varieties, &c. The 
most recent contribution on this subject is by M. Rousselet; but 
for the geology reference should be made to the Memoirs by 
Messrs. Medlicott and Mallet of the Geological Survey of India, 
as the more popular writers have given currency to very incorrect 
views on this aspect of the question.
