_Kuang-we_ has a population of seven millions, and furnishes the provincial city with large quantities of rice, cassia, iron, lead, fans, and wood of various kinds; and takes in return many native productions, and most of the articles that come to Canton from beyond sea. From _Kwei-chow_, one of the central provinces, are brought gold, quicksilver, iron, lead, tobacco, incense, and drugs; a few articles, chiefly foreign goods, find their way back to that province. Its population is five millions. From the two provinces, _Hoo-nan_ and _Hoo-pih_, come large quantities of rhubarb; also musk, tobacco, honey, hemp, and a great variety of singing-birds; the number of inhabitants is five millions. They make very considerable demands on the merchants of Canton, both for native productions and foreign imports. _Keang se_ sends to this market, coarse cloths, hemp, china-ware, and drugs; and receives in return woollens and native books. The population is twenty-three millions. _Ho-nan_ has an equal number of inhabitants, and sends hither rhubarb, musk, almonds, honey, indigo, &c.; woollens, and a few other foreign goods are received in return. [Sidenote: OPIUM.] This account of the domestic commerce of Canton, is taken from native manuscript. We have sought long, but in vain, for some official document which would show at once, the different kinds, and the amount of merchandise, which are annually brought from, and carried to, the several provinces of the empire. The account which has been given must be regarded only as an approximation to the truth. Some articles, doubtless, have been omitted, which ought to have been noticed, and vice versa; one commodity in particular, opium, known to be carried into all the provinces, and used to the amount of more than fifteen millions annually, is not even mentioned. Still, the statement which we have brought into view, shows that there is, in every part of the empire, a greater or less demand for foreign productions; a demand which, so long as the commerce is confined to this port, will be supplied very disadvantageously, both for the foreigner and the native; but while it does remain thus restricted, there is reason to suppose that it will, under all its disadvantages, gradually increase; and even if the northern ports of the empire should be immediately thrown open, it will not soon cease to be important.
