128                            Indian Diamonds.
The change from a grey to a red soil, consisting of weather-worn granitic gravel, is here distinctly seen. The upper layer consists of the black " Cotton soil " brought down from the higher grounds by floods. Beneath this layer lies a mass of fragments of sandstone, quartz, jasper-flint, and granite, with great amorphous masses of calca­reous conglomerate, but destitute of any indication of their having been rolled there by water. It is in this stratum that the Diamond is found ; but none of the mines about Mallivully or Golapally are now worked.
The locality known as Parteal or Gani-Parteal, on the north bank of the Kistna, has been regarded by some authorities as the original home of the historical "Pitt" or " Regent " Diamond. The Hyderabad (Deccan) Com­pany has for some years past been washing for Diamonds at Parteal or Partial. So important were the Diamond-workings in this district that by the Treaty of 1766, made between the Nizam and the East India Company, they were reserved to His Highness. The Diamond fields of Hyderabad have been visited and reported upon in recent years by several experts, as by Mr. Lowinsky in 1886, Mr. Theodore Hughes in 1887, and Mr. William Morgans in 1889.
The Diamond district of the Sumbulpur or Sambalpar group, in the Central Provinces, extends to the immediate vicinity of Sumbulpur, a city built on a fruitful alluvial table-land, 385 feet above the level of the sea, and situated between the rivers Mahanadi and Brahmini.
The Precious Stones which are found at the mouths of the little tributaries of the Maund, flowing from the north­east, are of various sizes and generally of the purest quality.
Although Diamonds are rarely, if ever, now found in Sumbulpur, it is interesting to preserve the description of the old Diamond-washers in the days of the Rajahs.
