The Baganda of Central Africa believe so strongly in the intimate relation between the intercourse of the sexes and the fertility of the ground that among them a barren wife is generally sent away, because she is supposed to prevent her husband's garden from bearing fruit. On the contrary, a couple who have given proof of extraordinary fertility by becoming the parents of twins are believed by the Baganda to be endowed with a corresponding power of increasing the fruitfulness of the plantain-trees, which furnish them with their staple food. Some little time after the birth of the twins a ceremony is performed, the object of which clearly is to transmit the reproductive virtue of the parents to the plantains. The mother lies down on her back in the thick grass near the house and places a flower of the plantain between her legs; then her husband comes and knocks the flower away with his genital member.
Further, the parents go through the country performing dances in the gardens of favoured friends, apparently for the purpose of causing the plantain-trees to bear fruit more abundantly.
In various parts of Europe customs have prevailed both at spring and harvest which are clearly based on the same crude notion that the relation of the human sexes to each other can be so used as to quicken the growth of plants. For example, in the Ukraine on St. George's Day (the twenty-third of April) the priest in his robes, attended by his acolytes, goes out to the fields of the village, where the crops are beginning to show green above the ground, and blesses them. After that the young married people lie down in couples on the sown fields and roll several times over on them, in the belief that this will promote the growth of the crops. In some parts of Russia the priest himself is rolled by women over the sprouting crop, and that without regard to the mud and holes which he may encounter in his beneficent progress.
If the shepherd resists or remonstrates, his flock murmurs, Little Father, you do not really wish us well, you do not wish us to have corn, although you do wish to live on our corn. In some parts of Germany at harvest the men and women, who have reaped the corn, roll together on the field. This again is probably a mitigation of an older and ruder custom designed to impart fertility to the fields by methods like those resorted to by the Pipiles of Central America long ago and by the cultivators of rice in Java at the present time.
To the student who cares to track the devious course of the human mind in its gropings after truth, it is of some interest to observe that the same theoretical belief in the sympathetic influence of the sexes on vegetation, which has led some peoples to indulge their passions as a means of fertilising the earth, has led others to seek the same end by directly opposite means.
