The Occurrence and Distribution of Diamonds in India, 583 
UDESNA. 
The mines were being worked at Udesna :— 
“There was water in all the pits, at what appears to be the level of 
the top of the boulder bed, under an irregular thickness of yellow clay, 
variously charged with kunkur and laterite gravel ; the gangue is a stiff 
gravelly clay.” 
SAKERIYA. 
“As at Udesna, there is a variable depth of clay, the middle third 
being kunkury and the lower lateritic; below this, the clay becomes 
charged with gravel, pebbles, and boulders, these rapidly increasing in 
size to great angular blocks of sandstone, scarcely moved from their 
original beds ; it is from between these that the best stuff is got, a stiff 
unctuous clay, with quartz gravel through it. Above these deep pits, 
which are never far from the stream, and well up on the slope of the 
Rewah sandstone are diggings in the surface lateritic gravel.” 
MusGoan. 
This, as suggested by Franklin, is probably the deserted gorge 
ofa stream. Mr. Medlicott writes :— 
“The filling in is certainly peculiar ; the structure is like course 
foliation, a net-work of strings of cale spar, inclosing laminz and small 
lumps of green clay. 
“In the only hole I saw they were working the yellow clay from the 
crevices of this; but the men told me that at a greater depth there are 
alternating layers of green mud, and of its mixture with cale spar in 
which diamonds are found.” 
Bocuin. 
The mines of Boghin are thus described by Mr. Medlicott :— 
« At the upper end of the gorge of the Boghin river there are two falls 
of 200 feet each, and there are workings throughout the whole length to 
Kalinjer. The principal diggings were at the lower end of the mine 
valley ; they were removing some twelve feet of dark, brown clayey sand 
to get at the boulder bed, in the base of which the diamonds are found, 
but both here and below the narrow gorge the gravel at the surface of 
the river bed is much worked. The natives spoke to me of a European 
who, some twenty years ago, had made an attempt at mining on a large 
scale. His diggings were on the flanks of the limestone hill, some fifty 
or one hundred feet over the river, the ore being a jasper gravel gathered 
from the deep surface crevices of the limestone. As well as I could 
understand their pronunciation, the man’s name was Berkeley, but I have 
not seen any written account of his experiment; the remains of his 
wash pits and picking floors are there still.”’* 
* Tt is probable that the European referred to is the same as the one mentioned in the 
extract below.
