The rest of the year passed in Brazil in quiet though important operations; many roads were opened through the still wild country in the interior; a naval academy was instituted; a school of anatomy was founded in the naval and military hospital; and the vaccine establishment formed in Brazil in 1804 having declined, it was renewed both at Bahia and Rio, and immense numbers of persons of all colours were vaccinated. Meanwhile the Portuguese arms were employed in another quarter of the world. The extensive dominions of Portugal in the east had fallen off one by one, as pearls from a broken thread. Yet Macao was still Portuguese. For twenty years past, it, in common with the coast of China, had been plagued with the pirates of the Yellow Sea; till, at length, the Chinese government found it necessary to take measures for suppressing them, and therefore made a treaty with the Portuguese government of Macao, signed by the following personages, on the 23d of November.

The Portuguese were by this treaty to furnish six vessels of from sixteen to twenty-six guns, but being in want of ball and other stores they were supplied liberally by the English East India Company's factory; and the result was, that after three months' resistance, the pirates surrendered their ships, and promised to become peaceable subjects, and the people of Macao performed a Te Deum in honour of their success; but twelve months elapsed ere the happy tidings reached Brazil. The great European interests of Brazil and its sovereign might have been forgotten in the country itself, during the year 1810, so tranquil was it, but for the packets which brought across the Atlantic the details of those desperate battles, which the strength and the treasure of England were waging in defence of them in the Peninsula. On the 19th of February, Lord Strangford and the Conde de Linhares, in behalf of their respective governments, signed a commercial treaty at Rio, by which great and reciprocal advantages were obtained, and the English were allowed the free exercise of their own form of worship, provided they built no steeples to their churches, and that they used no bells.
