It was the practice of these farmers-general to underlet to other Chinese the privilege of selling salt, supplying them with the article at a certain rate, and these under-farmers sold the salt again to the petty retailers in the public markets at an advanced price. The price of the salt, after passing through the hands of the farmers, varied not only according to the distance from the place of manufacture, but according to the capital and speculation of the under-farmer; if he adopted the liberal system of obtaining small profits upon a large sale, the market was abundantly supplied at a low rate; but if, on the contrary, he traded on a small capital, and enhanced the price by insufficiently answering the demand, the price became proportionally exorbitant. In some places, as at _Salátiga_ and _Ung'arang_, through which the salt was transported by inland carriage to the populous districts of the interior, the price was sometimes as high as one hundred and twenty, and even one hundred and forty Spanish dollars per _kóyan_, while along the coast, as at _Chéribon_ and _Surabáya_, it was as low as thirty, and at _Grésik_ twenty-five. The average in the year 1813, when the farming system was abolished, may be taken, one district with another, at about fifty-seven Spanish dollars the _kógan_, or rather less than thirty dollars per ton. The quantity usually calculated for the annual consumption of Java and _Madúra_, including about one thousand _kóyans_ estimated to be manufactured in the native provinces, is sixteen thousand _kóyans_, or thirty-two thousand tons. Under the arrangements now adopted for the manufacture and sale of this article, the average rate at which the manufacturers are paid is about six rupees the _kóyan_, including the charges of transport to the depôts, and the sale price varies from twenty-five to thirty-five Spanish dollars, according to the distance from the principal depôts; an adequate supply by means of smaller depôts is insured in every part of the country. The salt of Java exported to the other islands of the Archipelago, competes with that of Siam and the Coromandel coast, and generally supersedes it, both on account of its quality and cheapness. The exportation is free to all places except Bengal, where, on account of its interference with the monopoly there established, it has, since the conquest of Java, been found necessary to prohibit its importation under penalty of confiscation.
