Captain Wickham, R.N., was at Valparaiso in South America in the year 1836, where he met a purser in the American navy who had realized about 3000 pounds sterling; this person here quitted the American service and laid out his capital in the purchase of a small vessel in which, having embarked a cargo suited to the trade of the country, he started for the coast of California; in a short period he returned to Valparaiso, having in this single trip more than doubled his capital; this Captain Wickham also stated was by no means a rare instance. TRADING PRODUCTS OF THE SEVERAL ISLANDS. Having bestowed some attention on the state of trade in the Indian Archipelago, and collected considerable information from various individuals who had been engaged in it, I shall here subjoin a summary of such of the principal facts as I think may be depended on. TRADE WITH TIMOR. In all the ports of the natives, as well as those under the Dutch and Portuguese authorities, the produce is much the same. It consists chiefly of goats, pigs, poultry, maize, paddy, yams, plantains, fruit, sandalwood, beeswax, and tortoiseshell in small quantities. At Dili duties of 10 per cent are exacted and produce is rather dear. Sandalwood is to be had at from 2 to 4 dollars the picul of 125 catties; wax is generally from 30 to 35 dollars (Spanish) the picul of 110 catties. The ports of Timor furnish a little gold dust at times. Good water and firewood are to be had at most of them; that of Dili is a good and safe one. Gold dust, I understand, is also procurable at Sandalwood Island and New Hebrides. For vessels the good season on the coast is from about the 10th of April to the 15th of October. Cootababa affords horses and all the produce of the other places. No duties are levied here, the place not being subject to the Portuguese. It is a small port and should be entered with caution. The best ports of Timor for wax are Dili, Cootababa, Ocussi, Sitranny, Nilow, and Manatronto. It is gathered in June, cleaned in July, and sold principally in that and the two following months; but a vessel should be active, as enterprising people go along the coast and buy it up for the Kupang merchants, who send it to Batavia where it is said to sell for 120 rupees the picul; the price at Cootababa, being lately about 80 rupees at 2 1/2 to the Spanish dollar. Sandalwood can be had from March to October, the usual trading season; but from March to May is the best time as vessels from Kupang and Macao are on the coast early, buying it up in time to return to Macao and China in the favourable monsoon. The best ports for sandalwood are, Cootababa, Ocussi, and Sitranny, but it is to be had most abundantly at Ata-poopa. ARTICLES IN REQUEST. Spanish dollars, muskets, and gunpowder are the essentials for procuring wax or sandalwood, but if you wish to have a greater assortment, small quantities may be added of any articles from the following list.
