So much for Cuba. Let us now see what is doing in Brazil. The following article is extracted from the _Jamaica Times_, of 8th. October last. “Though it may be an act of supererogation to accumulate arguments in support of the proposition that an equalisation of the sugar duties must necessarily give an impetus to the slave-trade, it may not be amiss to point out such instances which may come before us of an illustrative tendency. In a communication recently addressed by Dr Lang to the British public, it is stated as an unquestionable fact, that a great stimulus to the cultivation of sugar in Brazil had been afforded by the late change in the duties; and consequently that the slave trade, which had been rapidly declining for some time past, had revived as briskly as ever, especially at Pernambuco, which is by far the most conveniently situated port in the empire for this traffic—being so far to the northward and eastward, and consequently so favourably situated for taking advantage of the south-east trade wind, that a vessel from that port may often run across to the coast, as it is called, that is to Africa, in half the time she would take either from Bahia or Rio Janeiro. A schooner of one hundred and twenty tons, the _Gallant Mary of Baltimore_, he added, had arrived at Pernambuco a day or two before his arrival, and was then lying in the harbour for sale; and during the short period of his stay she was purchased for seven hundred and fifty pounds by a slave merchant in the place, and was to be despatched to the coast a day or two after he sailed for England. “This is one instance of the manner in which the increased consumption of slave-grown sugar is acting as a premium to the slave trader. We offer a second in the fact recently communicated from Africa itself, that the slave-trade on the west coast was never more brisk than it is at present; that thirteen hundred and fifteen slaves had been landed from slave vessels at Sierra Leone from May 4th to June 28th of this year; that the last slaver taken was a Brazilian brig, although for deception called the Beulah of Portland, U.S.—she was sent in by the Waterwitch: this vessel had five hundred and ten slaves on board.
