The custom of families remaining together tends to the same result. The local importance of a large family in the country is weakened by its male members removing to town, or emigrating; consequently, the patriarch of three or four generations endeavors to retain his sons and grandsons around him, their houses joining his, and they and their families forming a social, united company. Such cases as those mentioned in the _Sacred Commands_ are of course rare, where nine generations of the family of Chang Kung-í inhabited one house, or of Chin, at whose table seven hundred mouths were daily fed,[154] but it is the tendency of society. This remark does not indicate that great landed proprietors exist, whose hereditary estates are secured by entail to the great injury of the state, as in Great Britain, for the farms are generally small and cultivated by the owner or on the metayer system. Families are supported on a more economical plan, the claims of kindred are better enforced, the land is cultivated with more care, and the local importance of the family perpetuated. This is, however, a very different system from that advocated by Fourier in France, or Greeley in America, for these little communities are placed under one natural head, whose authority is acknowledged and upheld, and his indignation feared. Workmen of the same profession form unions, each person contributing a certain sum on the promise of assistance when sick or disabled, and this custom prevents and alleviates a vast amount of poverty. ~RESTRICTIONS UPON EMIGRATION.~ The obstacles put in the way of emigrating beyond sea, both in law and prejudice, operate to deter respectable persons from leaving their native land. Necessity has made the law a dead letter, and thousands annually leave their homes. No better evidence of the dense population can be offered to those acquainted with Chinese feelings and character, than the extent of emigration. “What stronger proof,” observes Medhurst, “of the dense population of China could be afforded than the fact, that emigration is going on in spite of restrictions and disabilities, from a country where learning and civilization reign, and where all the dearest interests and prejudices of the emigrants are found, to lands like Burmah, Siam, Cambodia, Tibet, Manchuria, and the Indian Archipelago, where comparative ignorance and barbarity prevail, and where the extremes of a tropical or frozen region are to be exchanged for a mild and temperate climate? Added to this consideration, that not a single female is permitted or ventures to leave the country, when consequently, all the tender attachments that bind heart to heart must be burst asunder, and, perhaps, forever.”[155]
