The evil consequences resulting from precocious unions in this country are: diminished vigor and shortened life in the husband; faded beauty, blasted health, and premature old age in the mother, and a diminutive stature, debility of body and imbecility of mind, perhaps a strong predisposition to consumption, rickets, scrofula, etc., in the children. MARRIAGE SHOULD BE WHEN THE PARTIES ARE IN HEALTH.—I do not say that every ailment should be a bar to marriage or child-bearing. It is possible that prolapsis uteri may be benefited by a pregnancy and parturition. But if a woman has prolapsis uteri, or other ailment, it is a poor preparation for the burdens of gestation, and good health is an important qualification for the responsibilities of married life. No learning can be of more importance to a young lady than to know how to preserve health, and how to restore it when lost, for we cannot reasonably expect healthy children from unhealthy parents. There are numerous other complaints besides scrofula and insanity, inherited by children. If a wife is to be healthy and strong, she must use means; health will not come by wishing for it merely, and whether pleasant at first or not, habit will make early rising, temperate living, taking exercise, thorough ablution of the whole body, etc., easy. That state of vigorous health and strength which prepares a woman to bear strong and vigorous children, is attained not by idleness and luxury, and neglect of personal cleanliness, nor by tight lacing, the use of stimulants, nor by irregular modes of sleeping, etc., but by rising early, and taking early walks in the open air, and engaging in household labor, or other exercise during the day, going to bed betimes, living on an abundance of good, wholesome food, by daily ablutions, followed by rubbing the skin thoroughly, and in general by observing the laws of health. If a woman who has thus preserved her health, marry a man who has been equally careful to observe the laws of continence and hygiene, she may hope to be the mother of a healthy child, and a blessing to all. THE CONSTITUTION OF BOTH THE MALE AND FEMALE should be good and strong. It is not enough that the body be well developed, if there is at the same time a very feeble constitution. Even if the children of such parents seem to be hale looking and robust, they do not attain old age—are very liable to die young. If there is only a predisposition to disease, such as is often inherited, it may be very doubtful whether the parties ought to marry. If there is only a disposition to habits of intoxication or dissipation, or to gout, madness, scrofula, consumption, etc., in the man, we may advise the woman not to unite herself to him, for these diseases do not show themselves until called into action by some exciting cause.
