Now, on a cargo of $40,000, it would give the sum of $4,000 _Add_ to this $1,50 per pecul on sugar exported, which was equal, at the lowest calculation, to twenty-five per cent., on $40,000, which gives 10,000 _Also_, $3,50 per ton for charges 975 And presents, say 1,000 If there is added the _difference_ in the sale of the imported cargo to the king or to individuals, the estimate cannot be less than twenty per cent., and probably twice that amount would not cover the loss, 8,000 _Add_ to this an additional price paid to the king on the produce exported, say it was twenty per cent., is 8,000 Three months’ charter, arising from detention, at $900 per month 2,700 Three months’ loss of interest is 600 ------- $35,275 From this amount deduct the _single charge_ of 1,700 ticals per each Siamese fathom on the _breadth_ of vessels bringing merchandise. If only specie were brought, 1,500 ticals. Sixty-eight thousand ticals at sixty-one cents, on seventy-five feet beam, is 4,275 ------- Making a difference of not less than $31,000 The result is, that the treaty has secured to us a valuable branch of commerce which was entirely destroyed, and which will continue to increase vastly, as the Siamese recover from the serious disasters which resulted from the inundation of the valley of the Menam, for upward of three months, during the year 1831. _Exports from the river Menam (Siam) during the year 1832, showing the quantity and market value of each article._ NAMES OF EXPORTS.
