1713.

The success of the squadron under Du Guay-Trouin had been so marked that a second armament was equipped at the cost of private individuals, but with the assistance of the Government. Its objective point was Bahia; but its commander was of another stamp from that in which Du Guay-Trouin was cast. Bahia was spared; and he contented himself with a descent upon some of the smaller sugar-islands. The Portuguese colonies were, however, about to be relieved from further alarms by the Peace of Utrecht, by which they obtained the full sovereignty over both banks of the Amazons, France ceding, with much reluctance, all pretensions to the country between that river and the Oyapok. It was likewise stipulated that the French should not trade with Maranham.

1720.

The people of the Mines were thanked for the promptitude with which they had brought assistance for the deliverance of Rio; and S. Paulo, as being the capital of a captaincy, obtained the rank of a city. Some idea may be formed of the value of the yield of the mines at this time from the fact that, in the year 1714, the Government fifths were commuted for the equivalent of about £50,400 sterling. The commutation was, however, raised, three years later, by one-fourth. In the year 1720, the country of Minas Geraes was detached from S. Paulo and declared a separate captaincy.

Note.—The reader will, I fear, observe a want in this work, which has not by any means escaped the notice of the writer, but which he has found it impossible fully to supply. In almost every chapter there occur notices of large transactions in money, the coins quoted being those then current in Spain and Portugal, respectively. It would, of course, be possible to state approximately the relative value to a given standard of those various coins, respectively, at any one period; but the value of gold and silver coins of the same name varied so constantly and so considerably that it is impossible to lay down a definite standard of value throughout the whole area of which this work treats for any considerable part of the period to which it is devoted. As an instance of the tendency to mislead in taking any fixed coin as a standard in reference to South American monetary transactions, I may mention that, in Buenos Ayres, in the year 1866, I found the Argentine dollar, a coin which most English readers would naturally estimate as the equivalent of four shillings, to be worth exactly twopence. This, of course, applies to the paper dollar; but this would be the legal tender in payment of amounts stated in dollars, unless otherwise specified.

CHAPTER XII.
BRAZIL: DISCOVERY OF THE DIAMOND DISTRICT.
1724-1749.

1724.

The mining districts had on several occasions been the scene of serious and prolonged resistance against the constituted authorities, in consequence of the regulations respecting the mode of levying the royal share which were introduced with a view to prevent smuggling. It had been found necessary to make a severe example of the ringleaders of an insurrection; and the mining population were thenceforward amenable to law. It was established that all gold was to pass through the royal smelting-house before paying the royal fifths which were now re-established. The people of the mines had, by a timely discovery, escaped the danger of a negro insurrection; and in consequence so many negroes took to the woods that the same evil was apprehended as in the case of the Palmares. In order to avert such a contingency, Bush-captains were established, whose business it was to apprehend wandering negroes, for whom they received head-money from their masters. In many cases it was alleged that the Bush-captains, in order to receive the reward, made a practice of arresting negroes who were not runaways, and that this institution was only one degree less troublesome to the community than the evil which it was appointed to suppress—these individuals being likewise in the habit of detaining negroes and profiting by their labour.

The great importation of negroes into Minas Geraes gave occasion to fears which were not entertained elsewhere in Brazil, and in consequence an order was issued forbidding the formation of free blacks into separate companies, and requiring that they should be mixed with white soldiers. No person who was a mulatto within the fourth degree might be an ordinary judge or hold any municipal office in Minas Geraes. The mode of mining had now undergone a considerable alteration. Instead of opening cuttings and carrying the produce in bulk to be washed, water was conveyed to the mining ground, and, washing away the mould, broke up the blocks in pits or wooden troughs, thus saving a great expenditure of labour. As water-power thus became a valuable property, those in possession of water-courses derived great advantages therefrom. Their pretensions were, however, so extravagant that it was found necessary to establish a set of laws respecting the distribution of the water.
