quantities, as they found large rocks of crystal in many of the mountains whence the streams proceeded that washed down the diamonds. [Footnote 6: The author writes as of the year 1740.--E.] Soon after this discovery, it was represented to the king of Portugal, that if diamonds should be met with in such abundance as their sanguine expectations seemed to indicate, their value and estimation would be so debased as to ruin all the Europeans who had any quantity of East India diamonds in their possession, and would even render the discovery itself of no importance, and prevent his majesty from deriving any advantages from it. On these considerations, his majesty thought proper to restrain the general search for diamonds, and erected a diamond company, with an exclusive charter for this purpose; in which company, in consideration of a sum of money paid to the king, the property of all diamonds found in Brazil is vested: But, to hinder them from collecting too large quantities, and thereby reducing their value in the market, they are prohibited from employing above eight hundred slaves in this search. To prevent any of his other subjects from continuing the search, and to secure the company against interlopers, a large town, and considerable surrounding district, has been depopulated; and all the inhabitants, said to have amounted to six thousand, have been obliged to remove to another part of the country: For as this town and district were in the neighbourhood of the diamonds, it was thought impossible to prevent such a number of people from frequently smuggling, if allowed to reside on the spot.
