Many are the little children of three and a half, four and a half, and five years, that are still getting teeth, sent out in the streets to saunter along in the chill air of our hill-streets to some school-house. Heaven bless our schools, for they are invaluable; but may God change the minds of the people as to such early exposures, being best for the credit of our Commonwealth. In school at four and a half, and in the grave at five; or in school at five, and in some State Reform School at seven or eight! just when the mind is beginning to be formed. It is well known that diphtheria, pneumonia, and various contagious diseases are more prevalent where there has been some exciting cause. For instance, during the warm days at the breaking up of winter, when the snow is melting and the atmosphere is filled with vapors, one can see children of all ages wading about in running water, dragging sleds, moving snow; some heavily-clad feet well protected, while others are not supplied even with wraps, but with rubber boots, it may be, minus the toes. In a few days many deaths of this very class of children are reported in some locality or other. Children will sit or stand around in places injurious to the health, and will go into dangers where they seem really to be admired by some adults. In the hurry and excitement to go in the street, so much is lost of a chance to build a solid foundation either of health or character. I know it is hard to restrain little ones after they have tasted of so much freedom as is given them during the weakest period of childhood, the teething period. This is why I feel so anxious to do or say something that will assist parents to lighten their burdens in this matter. In the first place, let me advise, with all due feelings of respect, the entire abandonment of low, dark, bad-smelling, water-soaked basement kitchens to work in, and the adoption of a rule to live more on top of the ground, and less under the ground. The depression upon the system of any one who has been permitted to exercise in open daylight, is equal to that of being incarcerated. Some persons say they send children to school to get them out of the way; a child soon begins to know this, and gradually goes out of the way, until some aching tooth or biting pain sends him crying to his friend.
