The art of agriculture is coeval with the first establishment of the empire; and to this useful employment China mainly owes its grandeur and populousness. The enormous numbers of the people has caused the utmost attention to be paid to the art, and the cultivation of much of the country approaches as near as possible to garden-farming. Some parts of the country are mountainous and infertile, but the greater proportion of it is fruitful, and densely studded with houses. The hills and mountain-sides are terraced; the rocky fragments are gathered off the slopes, and formed into retaining-walls; and the wonders of Chinese irrigation have never been rivalled. Upon the decease of the parents, lands are divided among the male children, and, like all Orientals, the people cleave with great fondness to their patrimonial acres. Any one, by simply applying to Government, may obtain permission to reclaim waste land; and a wise exemption from all taxes, until it becomes productive, allows the cultivator to reap a proper reward for his industry and enterprise. The agricultural knowledge of China cannot vie with ours in point of science; but it is far more widely diffused. A uniform system of cultivation, the result of centuries of experience, is known to, and practised by, every cottar in the empire; and that system is indubitably unequalled by that of any other nation, unless it be our own. The steeping of seeds, and drilling in sowing, are practised, and have been so for ages; they never fail to seize promptly the proper season and weather for their farming operations; they take every advantage of their summer time by the system of double-cropping; and in the vitally important matters of manuring and irrigation, as well as in making the most of their land, they are unsurpassed, perhaps unrivalled, by any nation in the world.
