[825] Thus in Dawan (West Timor), when peace is made between the divorced couple, the party who caused the separation must pay the parents of the other five swine and five pieces of linen. A year's interval must elapse with the African Peulhs of Futa-Jallon. In Unyoro (Africa) the reunion is celebrated by slaughtering a beef; and among the Berbers of Dongola the divorced man gives the woman two pieces of cotton stuff: POST, _Familienrecht_, 265; _idem_, _Afrikanische Jurisprudenz_, I, 453.

FREQUENCY OF DIVORCE The laws of divorce among backward races, it is thus perceived, are full of interest for the student of social institutions. One comes from the study with a clearer perception of the fact that such institutions are but the outward expression of human life--of slow experience and experimentation; and one gains a deeper respect for the concrete results of primitive culture. Especially important is the relation of divorce to the stability of society. The conservatism prevailing even among rude peoples with respect to the liberty of divorce is remarkable. This may be due in part to the fact that primarily marriage does not rest so much upon the sexual instinct as upon family needs.[827] In some instances, where dissolution of the marriage is free to either party, or where it is the peculiar right of the man, divorce is exceedingly rare.[828] The American Indian tribes are conspicuous in this regard.[829] Sometimes there is a strong social sentiment against it. Such is the case in China. Formerly among the Japanese, like the ancient Aztecs, divorces were infrequent;[830] and among many less advanced peoples, such as the Afghans, the Veddahs, or even the Zulus, the sentiment of love is doubtless a stronger check upon instability of the family than is commonly supposed.[831] [827] STARCKE, _Primitive Family_, 258, 259.
