Enterprising individuals, merchants of Batavia, have not been wanting to engage in the valuable fur trade, hitherto carried on principally by the Americans, between Kamtschatka and China. Mr. Timmerman Thyssen, an enlightened Dutch gentleman, whose name for honourable dealing and extensive business has always stood high among the merchants of Batavia, has entered into more than one speculation of this kind. Vessels fitted out from Batavia took in furs at Kamtschatka, which were intended to be exchanged in China for dollars; but the dangers of the passage in one instance, and the informality of the papers in another, rendered this bold and promising enterprize productive of but little pecuniary advantage. Nothing, however, has occurred, to prove that the adventure would not have fully answered its intention in time of peace, the principal difficulties which attended and frustrated it ceasing with the war. Since the conquest a very extensive trade has been carried on by the English country ships importing from Calcutta, Madras, and Bombay, all kinds of piece goods, opium, and other articles, the returns for which have been usually made by bills, gold-dust, bees'-wax, tin, Japan camphor, sago, and teak timber. The piece goods of Western India have always formed an extensive article of import into Java, and the annual value of those latterly imported cannot well be estimated at less than a million of dollars. Those generally meet a ready sale, at an advance of from thirty to forty per cent. upon the prime cost in India, and much more when the supply is scanty.
