that his vitality, his power of resisting disease, is wasted.  She will know that by taking the necessary precautions, she may save the child’s life; that she must not take him thus chilled, to the fire or into a room highly heated, but that by gentle exercise or friction, she must restore the circulation of the blood, and in using such precautions, she may ward off the attacks of disease that would surely follow if they were neglected.  This is but a single case, for there are instances of almost daily occurrence when a proper knowledge of the laws of health will ward off disease, in her own case, as well as in those of various members of her household.  The diseases which carry off children, are for the most part, such as ought to be under the control of the women who love them, pet them, educate them, and who would, in many cases, lay down their lives for them.

Ignorance of the laws of ventilation in sleeping-rooms and school-rooms is the cause of a vast amount of disease.  From ignorance of the signs of approaching disease, children are often punished for idleness, listlessness, sulkiness and wilfulness, and this punishment is too often by confinement in a closed room, and by an increase of tasks; when what is really needed is more oxygen, more open-air exercise, and less study.  These forms of ignorance have too often resulted in malignant typhus and brain fevers.  Knowledge of the laws of hygiene will often spare the waste of health and strength in the young, and will also spare anxiety and misery to those who love and tend them.  If the time devoted to the many trashy so-called “accomplishments” in a young lady’s education, were given to a study of the laws of preserving health, how many precious lives might be spared to loving parents, and how many frail and delicate forms, resulting from inattention to physical training, might have become strong and beautiful temples of exalted souls.  We are all in duty bound to know and to obey the laws of nature, on which the welfare of our bodies depends, for the full enjoyment of our faculties can only be attained when the body is in perfect health.

IDLENESS A SOURCE OF MISERY.

Perhaps the greatest cause of misery and wretchedness in social life is idleness.  The want of something to do is what makes people wicked and miserable.  It breeds selfishness, mischief-making, envy, jealousy and vice, in all its most dreadful forms.  It is the duty of mothers to see that their daughters are trained to habits of industry, that their minds are at all times occupied, that they are well informed as to household duties, and to the duties of married life, for upon a knowledge of household details may depend their life-long happiness or misery.  It is frequently the case, that a girl’s education ends just as her mind is beginning to mature and her
