I had in Paris an opportunity of procuring information concerning the British whale fishery on the coast of Brazil, which it is proper to communicate to Congress, that if any advantage can be made of it the opportunity may not be lost. The last year and the year before the English carried on this fishery to very great advantage, off the river Plate in South America, in the latitude of 35° south, and from thence to 40°, just on the edge of soundings, off and on, as the sailors express it, and about longitude 65° from London. They had about seventeen vessels in this fishery, which all sailed from London in the months of September and October. All the officers and men Americans from Nantucket and Cape Cod, two or three from Rhode Island, and one from Long Island. Four or five of these vessels went to Greenland, to which place they sail yearly, the last of February or the beginning of March. The year before last, there was published in the English newspapers, a letter from the Lords of the Admiralty to Dennis de Bredt, in Coleman Street, informing him, that a convoy should be appointed to the Brazil fleet. But this I had certain information was a forgery, calculated merely to deceive American privateers, and no convoy actually went or was appointed, either last year or the year before, although the imposture was repeated both times, and will no doubt be renewed this. For the capture or destruction of a fishery so wholly defenceless, not one of the vessels having any arms, a single frigate, or indeed a privateer of four and twenty guns, would be sufficient. The beginning of December would be the best time to proceed from Boston or Philadelphia, because the frigate would then find the whaling vessels nearly loaded. The cargoes of bone and oil are very valuable, and at least four hundred and fifty of the best kind of seamen would be taken out of the hands of the English, and might be gained into the American service. Most of the officers and men wish well to this country, and would gladly be in its service, if they could be delivered from that they are engaged in. Whenever the English men of war or privateers, have taken an American vessel, they have given to all the whalemen found among the crew, by order of government, their choice, either to go on board a man of war and fight against their country, or into the whale fishery. Such numbers have chosen the latter, as have made up the crews of seventeen vessels.
