But the eggs, or ova—which is the Latin word meaning eggs—do not begin to ripen until the girl reaches the age of thirteen or fourteen, or, in other words, until she begins to become a woman. This passing away of the ovum (singular of ova) is called ovulation, and it occurs in the woman about every twenty-eight days. The uterus is lined by a mucous membrane similar to that which lines the mouth, and at this time of ovulation this membrane becomes swollen and soft, and little hemorrhages, or bleedings, occur for three or four days, the blood passing away through the vagina. This is called menstruation.

Sometimes, when girls have not been told beforehand of the facts of menstruation, they become greatly frightened at seeing this blood and imagine that they have some dreadful disease. If they have no friend to whom they can speak freely they sometimes do very injudicious things in their efforts to remove that which to them seems so strange and inexplicable. I have known of girls who washed their clothes in cold water and put them on wet, and so took cold and perhaps checked the menstrual flow, and as a consequence were injured for life, or may even have died years after as a result of this unwise conduct.

The girl who is wisely taught will recognize in this the outward sign of the fact that she has reached womanhood, that she has entered upon what is called the maternal period of a woman's life, the period when it is possible for her to become a mother.

This does not mean that she should become a mother while so young. It only means that the sex organs are so far developed that they are beginning to take up their peculiar functions. But they are like the immature buds of the flower, and need time for a perfect development. If she understands this, and recognizes her added value to the world through the perfecting of her entire organism, she will desire to take good care of herself, and during these years of early young womanhood to develop into all that is possible of sweetness, grace, purity, and all true womanliness.

Girls who are not wisely taught sometimes feel that this new physical function is a vexatious hindrance to their happiness. It is often accompanied with pain, and its periodical recurrence interferes with their plans for pleasure, and they in ignorance sometimes say, rebelliously, "O, I hate being a woman!"

A young woman once came to consult me professionally. She was a well-formed, good-looking girl, to all outward appearance lacking nothing in her physical make-up; but she was now twenty-two and had never menstruated, so she was aware that for some reason she was not like other girls. She came to ask me to make an examination and find out, if possible, what was wrong. She was engaged to be married, and knew that motherhood was in some way connected with menstruation, and she thought it might be possible that her physical condition would preclude the possibility of her becoming a mother, and, if so, it would be dishonorable to marry. Upon examination I discovered that all the organs of reproduction were lacking. When I disclosed this fact to her she exclaimed, with sadness, "Oh, why was I not made like other girls? I have heard them complain because they were girls, but I think if they were in my place, and knew that they could never have a home and children of their own, they would feel they had greater reason then to complain."

I think so, too. We seldom think of the fact that upon sex depend all the sweet ties of home and family. It is because of sex that we are fathers, mothers and children; that we have the dear family life, with its anniversaries of weddings and birthdays. It is through sex that the "desolate of the earth are set in families," and love and generosity have sway instead of selfishness. For this reason we ought to regard sex with reverent thought, to hold it sacred to the highest purposes, to speak of it ever with purest delicacy, and never with jesting or prurient smiles. I do not want you to center your thought on the physical facts of sex, but I would like to have you feel that womanhood, which is the mental, moral and physical expression of sex, is a glorious, divine gift, to be received with solemn thankfulness.

I want you, for the sake of a perfect womanhood, to take care of your bodily health, and yet I do not want you to feel that a woman must of necessity be a periodical semi-invalid.
