The rice land of Province Wellesley gives an average return of 1171/2 fold; the maximum degree of productiveness being 600 guntangs of paddy to an orlong of well flooded, alluvial land, or 150 fold, equal to 300 guntangs of clean rice, weighing nearly 4,520 English pounds.  The present average produce has been very moderately estimated at 470 guntangs the orlong of paddy.  The quantity of seed invariably allotted for an orlong of land is four guntangs.  In Siam forty fold is estimated a good average produce.  At Tavoy, on the Tenasserim coast, the maximum rate of productiveness of the rice land was, in 1825, and is still believed to be, nearly the same as the average of Siam; while their average was only twenty-fold.—­(Low, on “Straits Settlements.”)

Rice in Cochin-China is the “staff of life,” and forms the main article of culture.  There are six different sorts grown; two on the uplands, used for confectionery, and yielding only one crop annually; the other sorts affording from two to five crops a year; but generally two, one in April and another in October; or three when the inundations have been profuse.

The late Dr. Gutzlaff stated, at a meeting of the Statistical Society of London, that the population of China was about 367,000,000, and the returns of the land subject to tax as used in rice cultivation there, gave nearly half an acre to each living person; and he further stated that in the southern and well watered provinces, it is anything but uncommon to take two crops of rice, one of wheat, and one of pulse, from the same land in a single season.  Rice is the only article the Chinese ever offer a bounty for; the price fluctuates according to the seasons, from one and three-quarter dollars to eight dollars per picul.  Siam and the Indian Islands, particularly Bali and Lombok, supply the empire occasionally with large quantities.

The price of rice in China varies according to the state of the canals leading to the interior; if they are full of water the prices rise; if on the contrary they are low, prices fall in proportion at the producing districts.  The amount of consumption is controlled, in a considerable degree, by the cost of transit; when this is cheap prices rise from the general demand; but when land-carriage to any extent has to be resorted to, they fall; it raises prices so much at any great distance, that rice must be used very sparingly, from its enhanced price.  It is obvious that if the waters are sufficiently high to allow a boat to pass fully loaded, she does so at an expense of nearly 50 per cent, less than she would do, if, from want of water, she could only take half the quantity; when transport is cheap every one obtains a full supply; when it is dear the rice districts have more than they can consume.

At home we are so much accustomed to the facilities of transit offered by railroads, canal boats, &c., that we do not readily take into consideration, that in China, except by water, all articles are conveyed from one place to another on men’s shoulders.  Taking the population of Canton at the usual estimate of a million, and allowing to each a catty a day, the quantity of rice required for one day’s consumption alone in that city would be 10,000 piculs, of 133 lbs. each = 1,340,000 lbs.
