DIAMONDS.
Since, however, he elsewhere gives a list of nine stages between this locality and Golconda, the aggre­gate distance being 68 French leagues, or, say, 189 English miles, I was at first inclined to believe that the distances from Visapour and Golconda had been transposed. This being admitted, there was no difficulty in identifying Raolconda with the modern Rawdu-conda, in Lat. 15° 41', Long. 76° 50' in the Nizam of Haidrabad's territory. But after consultation with Mr. King, I now think that the place must have been near to, if not identical with, Ramulkota. Tavernier says:—
The strata containing the diamonds ranged from half an inch to an inch in thickness, and the gangue was hooked out with iron rods. Some of the stones were valued at from two to sixteen thousand crowns. The steel wheel was used for cutting.*
Tavernier gives an account of the polishing of the
gems as practised here. His account of the great security of property and system, with reference to the. sale of diamonds, together with the courtesy with which he was treated, will be read generally with interest.
KlSTNA AND GODAVERI DISTRICTS.
The principal mines in these districts are situated on the banks of the Kistna, or Krishna. They are named Golapilly, Malavilly, Purtial, Gani-Coulour = Kollur, &c.
