These silks cost three hundred and thirty-five thousand pesos. They will, with the condescension of his Majesty, be taken to Peru (as is done, that other silks of China may not be taken from Nueva Espana), and are sold at Lima at the following prices. Each libra of silk of the quality named in the first item, at fifteen pesos, the one thousand picos amounting to one million nine hundred and fifty thousand pesos. Each piece of Canton satin at fifty pesos, the ten thousand pieces amounting to five hundred thousand pesos. Each piece of damask at forty pesos, the ten thousand pieces amounting to four hundred thousand pesos. Each piece of gorgoran at ten pesos, the twenty thousand pieces amounting to two hundred thousand pesos. Each vara of velvet at four pesos, the thirty thousand varas amounting to one hundred and twenty thousand pesos. Taking from this amount the three hundred and thirty-five thousand pesos that those goods cost in China, and eight hundred and thirty-five thousand pesos for the cost of factors and of navigation, and whatever else their handling may cost, there is a net gain of two million pesos. In that way his Majesty can obtain every year from Filipinas five million seven hundred thousand pesos net, after deducting the entire cost. [The following list is from an undated memorial of probably the early seventeenth century which treats of the merchandise that the Portuguese were wont to take from China to Japan. The memorial first defines the value of certain coins and weights and measures.] First, the _tae_ is equivalent to a ducado of ten reals of gold or silver; a _maz_ is equal to one of our reals. One _maz_ is equivalent to ten _conderins_; each _conderin_ being valued at six maravedis, is divided into ten _caxes_, each _cax_ [_i.e.,_ cash] being a round brass coin half the size of a half cuarto [60] pierced with four holes, and with certain characters around the edge. One hundred of them make one maz; and it is the only coin that is stamped with a die, for all the others circulate by weight. _Ranquel_ are ten pieces of plate or crockery-ware. _Pico_ is equivalent to one quintal, but has one arroba more than ours. _Cate_ is a weight of twenty onzas. The ship of the Portuguese carries from five to six hundred picos of white untwisted silk. It costs at Canton eighty taes per pico delivered in Macan, and is sold in Xapon for one hundred and forty or one hundred and fifty taes. Laden with _retros_ (the fine red silk), of four or five hundred picos of all colors, at a cost of one hundred and forty taes, it is sold in Xapon at three hundred and seventy and sometimes four hundred taes. The common assorted _retros_ costs from fifty-five to sixty taes in Canton, according to its quality, and is sold in Xapon for one hundred taes. The silk of the _darca_, of all colors, is worth forty taes in Canton, and is sold by the libra in Xapon at nine maces per cate.
