A Voyage Round the World in the Years MDCCXL, I, II, III, IV. Baron George Anson Anson
of ships, guns, and men, and every circumstance which he could suppose our enemy desirous of being acquainted with. And the same perfidy every British cruiser may expect who touches at St. Catherine's while it is under the government of Don Jose Sylva de Paz.
Thus much, with what we shall be necessitated to relate in the course of our own proceedings, may suffice as to the present state of St. Catherine's, and the character of its governor. But as the reader may be desirous of knowing to what causes the late new modelling of this settlement is owing; to satisfy him in this particular, it will be necessary to give a short account of the adjacent continent of Brazil, and of the wonderful discoveries which have been made there within these last forty years, which, from a country of but mean estimation, has rendered it now perhaps the most considerable colony on the face of the globe.
This country was first discovered by Americus Vesputio, a Florentine, who had the good fortune to be honoured with giving his name to the immense continent, some time before found out by Columbus. Vesputio being in the service of the Portuguese, it was settled and planted by that nation, and, with the other dominions of Portugal, devolved to the crown of Spain when that kingdom became subject to it. During the long war between Spain and the States of Holland, the Dutch possessed themselves of the northermost part of Brazil, and were masters of it for some years. But when the Portuguese revolted from the Spanish Government, this country took part in the revolt, and soon re-possessed themselves of the places the Dutch had taken; since which time it has continued without interruption under the crown of Portugal, being, till the beginning of the present century, only productive of sugar and tobacco, and a few other commodities of very little account.
But this country, which for many years was only considered for the produce of its plantations, has been lately discovered to abound with the two minerals which mankind hold in the greatest esteem, and which they exert their utmost art and industry in acquiring, I mean gold and diamonds. Gold was first found in the mountains which lie adjacent to the city of Rio Janeiro. The occasion of its discovery is variously related, but the most common account is, that the Indians lying on the back of the Portuguese settlements, were observed by the soldiers employed in an expedition against them, to make use of this metal for their fish-hooks, and their manner of procuring it being enquired into, it appeared that great quantities of it were annually washed from the hills, and left amongst the sand and gravel, which remained in the vallies after the running off, or evaporation of the water. It is now little more than forty years since any quantities of gold worth notice have been imported to Europe from Brazil, but since that time the annual imports from thence 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. And it is now said that there is a small slender vein of it spread through all the country at about twenty-four feet from the surface, but that this vein is too thin and poor to answer the expence of digging; 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 b the sands, thereby saving the expences of digging: so that it is esteemed an infallible gain to be able to divert a stream from its channel, and to ransack its bed. From this account of gathering this metal, it should follow that there are properly no gold mines in Brazil; and this the governor of Rio Grande (who being at St. Catherine's, frequently visited Mr. Anson) did most confidently affirm, assuring us that the gold was all collected either from rivers, or from the beds of torrents after floods. It is indeed asserted, that in the mountains large rocks are found abounding with this metal, and I myself have seen the fragment of one of these rocks, with a considerable lump of gold intangled in it; but even in this case the workmen break off the rocks, and do not properly mine into them, and the great expence in subsisting among these mountains, and afterwards in separating the metal from the stone, makes this method of procuring gold to be but rarely put in practice.
The examining the bottoms of rivers and the gullies of torrents, and the washing the gold found therein from the sand and dirt with which it is always mixed, are works performed by slaves, who are principally negroes, kept in great numbers by the Portuguese for these purposes. The regulation of the duty of these slaves is singular, for they are each of them obliged to furnish their master with the eighth part of an ounce of gold per diem; and if they are either so fortunate or industrious as to collect a greater quantity, the surplus is considered as their own property, and they have the liberty of disposing of it as they think fit. So that it is said, some negroes who have accidentally fallen upon rich washing places have themselves purchased slaves, and have lived afterwards in great splendour, their original master having no other demand on them than the daily supply of the forementioned eighth, which, as the Portuguese ounce is somewhat lighter than our troy ounce, may amount to about nine shillings sterling.
The quantity of gold thus collected in the Brazils, and returned annually to Lisbon, may be in some degree estimated from the amount of the king's fifth. This hath of late been esteemed, one year with another, to be one hundred and fifty arroves of 32 lb. Portuguese weight each, which at £4 the troy ounce, makes very near £300,000 sterling, and consequently the capital, of which this is the fifth, is about a million and a half sterling. It is obvious that the annual return of gold to Lisbon cannot be less than this, though it be difficult to determine how much it exceeds it; perhaps we may not be very much mistaken in our conjecture, if we suppose the gold exchanged for silver with the Spaniards at Buenos Ayres, and what is brought privily to Europe and escapes the duty, amounts to near half a million more, which will make the whole annual produce of the Brazilian gold near two millions sterling, a prodigious sum to be found in a country which a few years since was not known to furnish a single grain.
I have already mentioned that besides gold this country does likewise produce diamonds. The discovery of these valuable stones is much more recent than that of gold, it being as yet scarce 20 years since the first were brought to Europe. They are found in the same manner as the gold, in the gullies of torrents and beds of rivers, but only in particular places, and not so universally spread through the country. They were often found in washing the gold before they were known to be diamonds, and were consequently thrown away with the sand and gravel separated from it; and it is very well remembered that numbers of very large stones, which would have made the fortunes of the possessors, have passed unregarded through the hands of those who now with impatience support the mortifying reflection. However, about twenty years since a person acquainted with the appearance of rough diamonds conceived that these pebbles, as they were then esteemed, were of the same kind: but it is said that there was a considerable interval between the first starting of this opinion and the confirmation of it by proper trials and examination, it proving difficult to persuade the inhabitants that what they had been long accustomed to despise could be of the importance represented by this discovery, and I have been informed that in this interval a governor of one of their places procured a good number of these stones, which he pretended to make use of at cards to mark with instead of counters. But it was at last confirmed by skilful jewellers in Europe, consulted on this occasion, that the stones thus found in Brazil were truly diamonds, many of which were not inferior, either in lustre, or any other quality, to those of the East Indies. On this determination, the Portuguese, in the neighbourhood of those places where they had first been observed, set themselves to search for them with great assiduity. And they were not without great hopes of discovering considerable masses of them, as they found large rocks of chrystal in many of the mountains, from whence the streams came which washed down the diamonds.
But it was soon represented to the King of Portugal that if such plenty of diamonds should be met with, as their sanguine conjectures seemed to indicate, this would so debase their value and diminish their estimation, that besides ruining all the Europeans who had any quantity of Indian diamonds in their possession, it would render the discovery itself of no importance, and would prevent his majesty from receiving any advantages from it, and on these considerations his majesty has thought proper to restrain the general search of diamonds, and has erected a diamond company for that purpose, with an exclusive charter. This company, in consideration of a sum paid to the king, is vested with the property of all diamonds found in Brazil: but to hinder their collecting too large quantities, and thereby reducing their value, they are prohibited from employing above eight hundred slaves in searching after them. And to prevent any of his other subjects from acting
