Through the very great increase of this trade--which was harmful and prejudicial to the Spanish merchants who shipped goods to Peru and Nueva Espana, and to the royal duties collected on the shipments from Espana--and through the business men of Mexico and Peru having become greedy of trade and commerce with the Filipinas, by means of their agents and factors, so that the trade with Espana was ceasing in great measure, and the merchants were sending to the Filipinas for their investments great consignments of silver, which by that means flowed yearly from his Majesty's kingdoms, to fall into the possession of infidels: all persons of Nueva Espana and Peru were prohibited from trading and engaging in commerce in the Filipinas, and from taking the Chinese merchandise to those regions. [231] Permission was given to the inhabitants and residents of the Filipinas that they alone might trade in the said merchandise, and export it. They are to take these goods themselves, or send them with persons who belong to the islands, so that they may sell them. From the proceeds of the said merchandise, they may not carry to the Filipinas more than five hundred thousand pesos each year. [232] A considerable number of _somas_ and junks (which are large vessels) generally come from Great China to Manila, laden with merchandise. Every year thirty or even forty ships are wont to come, and although they do not come together, in the form of a trading and war fleet, still they do come in groups with the monsoon and settled weather, which is generally at the new moon in March. They belong to the provinces of Canton, Chincheo, and Ucheo [Fo-Kien], and sail from those provinces. They make their voyage to the city of Manila in fifteen or twenty days, sell their merchandise, and return in good season, before the vendavals set in--the end of May and a few days of June--in order not to endanger their voyage.
