First of all, I want to point out to you that though as girls and women, we have many a high calling, and though there are many high purposes for us to follow, and many sweet uses for us to serve, our highest calling is this: to be the helpmate of man. However we may twist and turn our destinies, we shall never in this world find a higher calling. Women is not only to be man's mate, but his helpmate. She is to help him. Keep that in mind, and do not let it go: to help him.

With regard to the engagement ring, the finest and most considerate courtesy demands that the suitor consult the girl's taste and not his own in its selection. He may, however, buy the ring without consulting her if he sees fit. All the precious stones have their meaning: the diamond, which symbolizes purity and perfection, is the most graceful tribute to the bride-to-be; and so is the sapphire, the blue stone of perfect faith and trustfulness. The ruby is a token of the giver's passion, his ardent love for the one to whom it is given; but pearls, emblems of tears, and the opal, the stone off ill luck, are to be avoided.

But if you will preserve the twin principles of being both mannerly and charming in bed, you can go forth on your matrimonial career without fear. You hold the key in your hands, You know the rules, Life up to them. Don't lie down on your bed manners when you lie down on your bed.

Many young married people are ruined before their "crane is hung." Ruined through the false vanity engendered by the foolish display made in their attempts to follow the fashion in the preparations for the wedding, and their start in life.
