=The basic incentive for marriage.=--A completed home embraces a father, mother and one or more children, bound together by natural love for each other. The initial step in home building is taken when a man and woman decide to assume the duties, responsibilities and functions of marriage. Courtship and marriage may be prompted by a number of motives. There is but one natural and worthy motive--LOVE. This motive may be a little out of date in some circles, but it remains essential to a normal home, a happy productive home. This expression of love is awakened to conscious activity through acquaintance and friendship, becomes a joyful reality in courtship, is consummated in marriage and is perpetuated through life, because of a chaste, pure, unselfish sex preference of one man for one woman and that one woman for that one man. If for any reason, this sex preference is ever broken, the bonds of love between husband and wife will be weakened, if not severed for all time. This bond of union may be broken in a number of ways. There may be other causes of domestic inharmony, all of which can be adjusted so long as sex preference, or love, binds the two as one. Under the guidance of unselfish sex selection, few mistakes would ever be made, in the choice of a companion. =The tests of true love.=--A man and woman bound by pure love for each other, may live in a shack or a humble rented cottage, they may have to toil late and hard to support a family of growing children, but they and the children will be happy and usually healthy and strong, bound together by mutual love. They will remain true to each other through adversity, sickness and death. =Mismated.=--If husband and wife are not bound to each other by a natural sex preference, or love, though they may hold in their possession broad acres of land, railroad bonds and heavy deposits in the bank, live in a mansion and move in the élite circles of society, they will not love each other, their children, or be able to build a REAL home. =Other incentives for marriage.=--It is quite customary, [Illustration: A GOOD ARGUMENT FOR PURE LIVING] in some grades of society, to choose a life companion for social or financial advantage. Such unions are not natural. They are cold business transactions. A man prompted by these motives sees in a woman the qualities of a good housekeeper, a social queen, or a financial gain. A woman prompted by unnatural motives sees in a man opportunities for social prestige, a life of luxury and ease. They drift apart instead of their personalities blending, through love, as one. Soon he spends his days in his daily vocation and his evenings in the lodges. She finds her only pleasure in following the latest fashions and devoting her time to various social functions. Each have their secrets and manage to avoid public disgrace.
