Note (return) — Chapter XIV · VOYAGE ROUND THE WORLD, BY CAPTAIN GEORGE ANSON, IN THE YEARS 1740-1744.1 (continued 2)

Gold was first found in the mountains adjacent to the city of Rio Janeiro. The occasion of its discovery is variously related, but the most common account is, that the Indians dwelling on the back of the Portuguese settlements were observed, by the soldiers employed in an expedition against them, to use this metal for fish-hooks; and, on enquiry into their manner of procuring this precious metal, it appeared that great quantities of it were annually washed from the hills, and left among the sand and gravel which remained in the vallies after the running off or evaporation of the water. It is now [in 1740] little more than forty years since any quantities of gold, worth notice, have been imported from Brazil to Europe; but, since that time, the annual imports have been continually augmented by the discovery of places in other provinces, where it is to be met with as plentifully as at first about Rio Janeiro. It is alleged that a slender vein4 of gold spread through all the country, at about twenty-four feet below the surface, but that this vein is too thin and poor to answer the expence of digging.5 However, where the rivers or rains have had any course for a considerable time, there gold is always to be collected, the water having separated the metal from the earth, and deposited it in the sands, thereby saving the expence of digging; hence it is esteemed an infallible gain to be able to divert a stream from its channel, and ransack its bed. From this account of the manner of gathering gold, it should follow that there are no mines of this metal in Brazil, and this the governor of Rio Grande, who happened to be at St Catharines, and frequently visited Mr Anson, did most confidently affirm, assuring us that all the gold was collected from rivers, or from the beds of torrents after floods. It is indeed asserted that large rocks are found in the mountains abounding in gold, and I have seen a fragment of one of these rocks having a considerable lump of gold entangled in it; but, even in this case, the workmen only break off the rocks, and do not properly mine into them; and the great expence of subsisting among these mountains, and in afterwards separating the metal from the stone, occasions this method of procuring gold to be but rarely put in practice.
