In Japan, polygamy and fornication are allowed, and fathers sell or hire out their daughters with legal formalities for limited terms. In Finland it was the custom for a young woman to wear suspended at her girdle the sheath of a knife, as a sign that she was single and wanted a husband. Any young man who was enamored of her, obtained a knife in the shape of the sheath, and slyly slipped it in the latter, and if the maiden favored the proposal, she would keep the knife, otherwise she would return it. In another part of Finland, a young couple were allowed to sleep together, partly, if not completely dressed, for two weeks, which custom, called bundling or tarrying, was common in Wales and the New England States, and is supposed not to have resulted in immoral consequences. In Scotland, the custom has long prevailed of lifting the bride over the threshold of her new home, which custom is probably derived from the Romans. The threshold, in many countries, is thought to be a sacred limit or boundary, and is the subject of much superstition. In the Isle of Man, a superstition prevails that it is very lucky to carry salt in the pocket, and the natives always do so when they marry. They also have the international custom of throwing an old shoe after the bridegroom as he left his home, and also one or more after the bride as she left her home. In Wales the old-time weddings were characterized by several curious customs, such as Bundlings, Chainings, Sandings, Huntings and Tithings. In Britain, before Caesar's invasion, an indiscriminate (or but slightly restricted) intermixture of the sexes was the practice, and polygamy prevailed; and it was not uncommon for several brothers to have only one wife among them, paternity being determined by resemblance. The foregoing facts and customs do not show the evolution of marriage, because in some countries the same forms and customs prevail to-day that prevailed six thousand years ago. As civilization advances, however, we find that the tendency is toward a more rigid enforcement of the marriage contract, and strictly against polygamy. The sanctity of the home and respect for marriage vows have not only passed into the statute law of civilized nations, but they have become proverbial with most all of the enlightened people. It must also be observed, however, that at the present time there seems to be a tendency in this country to make marriage more difficult and divorce more easy.
