To this estimation of the produce of the goldand silver from Spanish America must be nowadded the gold furnished by the Portuguese ter-ritories in Brazil. Humboldt estimates theirannual produce in the year 1800 at four millionthree hundred and sixty thousand dollars. Hiscalculations do not, from any thing that appears,seem to have been drawn from any statisticalaccounts, and can be no safe guide. For the firsthalf of the century no notices but those of tooloose a nature to deserve confidence have beenattainable. In the appendix to the report of thebullion committee of the House of Commons inJune 1810, there is an account of the produce ofthe quintos, or duty of one-fifth from the 1st ofAugust 1751, to 31st of December 1794, for thetwo greatest mining provinces of Brazil , those ofMinas Geraes , and of Minas Novas; and also ofthe district of Goiazes. There were other minesin Brazil, in Cuiaba , Jacobina, and Matagroso,
