chap, xv DIAMOND MINE OF RAMMALAKOTA 43
are the only places in the world where the diamond is found.1
The first of the mines which I visited is situated in the territory of the King of Bïjâpur in the Province of Carnatic, and the locality is called Rammalakota,2 situated five days journey from Golkonda,3 and eight or nine from Bïjâpur. The fact that the two Kings of Golkonda and Bïjâpur were formerly;subject to the Mogul, and were then only Governors of the Provinces which they acquired by their revolt, caused it to be said, and to be still said by some people, that the diamonds come from the Empire of the Great Mogul. It is only about 200 years since this mine of Rammalakota was discovered, at least so far as I have been able to ascertain from the people of the country.4
All round the place where the diamonds are found the soil is sandy, and full of rocks and jungle, somewhat com­parable to the neighbourhood of Fontainebleau. There are in these rocks many veins, some of half a finger and some of a whole finger in width ; and the miners have small irons, crooked at the ends, which they thrust into the veins to draw from them the sand or earth,5 which they place in vessels ; it is in this earth that they afterwards find the

By means of the route given on p. 73 this locality has been identified with Rammalakota, about 20 miles south of Karnul (Kurnool), where excavations are to be seen to this day (Economic Geology of India, p. 15). The position is fairly indicated on the small map of India which accompanies the Revised French edition of Taverniere Travels, published at Rouen in 1713. The identification both of it and Coulour have foiled many investigators both in this and the last century. But it is needless to refer here to the various suggestions as to their identification, as the question is now fully set at rest by the identification of the stages on the routes to these mines.
' On p. 73 the distance is given as being 17 gos or 68 French leagues. The true distance by the direct route is about 120 English miles.
4 This evidence for the antiquity of the mine is of but little value, and cannot be relied on.
* This description and what follows indicate that the mining was carried on in the rock, not in detrital beds. It is, indeed, now known that the matrix at Rammalakota is an old pebble conglomerate belonging to the ' Karnül ' series.
