Children employed as varnishers in cheap furniture factories inhale poisonous fumes all day long and suffer from a variety of intestinal troubles in consequence. The gilding of picture frames produces a stiffening of the fingers. The children who are employed in the manufacture of wall papers and poisonous paints suffer from slow poisoning. The naptha fumes in the manufacture of rubber goods produce paralysis and premature decay.  Children employed in morocco leather works are often nauseated and fall easy victims to consumption. The little boys who make matches, and the little girls who pack them in boxes, suffer from phosphorous necrosis, or "phossy-jaw," a gangrene of the lower jaw due to phosphor poisoning.  Boys employed in the type foundries and stereotyping establishments are employed on the most dangerous part of the work, namely, rubbing the type and the plates, and lead poisoning is excessively prevalent among them as a result.  Little girls who work in the hosiery mills and carry heavy baskets from one floor to another, and their sisters who run machines by foot-power, suffer all through their life as a result of their employment. Girls who work in factories where caramels and other kinds of candies are made are constantly passing from the refrigerating department, where the temperature is perhaps 20 degrees Fahr., to other departments with temperatures as high as 80 or 90 degrees. As a result, they suffer from bronchial troubles.

These are only a few of the many occupations of children that are inherently unhealthful and should be prohibited entirely for children and all young persons under eighteen years of age. In a few instances it might be sufficient to fix the minimum age for employment at sixteen, if certain improvements in the conditions of employment were insisted upon.  Other dangers to health, such as the quick transition from the heat of the factory to the cold outside air, have already been noted. They are highly important causes of disease, though not inherent in the occupation itself in most cases.  A careful study of the child-labor problem from this largely neglected point of view would be most valuable.  When to the many dangers of health are added the dangers to life and limb from accidents, far more numerous among child workers than adults, the price we pay for the altogether unnecessary and uneconomic service of children would, in the Boer patriot's phrase, "stagger humanity," if it could be comprehended.

No combination of figures can give any idea of that price. Statistics cannot express the withering of child lips in the poisoned air of factories; the tired, strained look of child eyes that never dance to the glad music of souls tuned to Nature’s symphonies; the binding to wheels of industry the little bodies and souls that should be free, as the stars are free to shine and the flowers are free to drink the evening dews. Statistics may be perfected to the extent of giving the number of child workers with accuracy, the number maimed by dangerous machines, and the number who die year by year, but they can never give the spritual loss, if  I may use that word in its secular, scientific sense. Who shall tally the deaths of childhood’s hopes, ambitions, and dreams? How shall figures show the silent atrophy of potential genius, the brutalizing of potential love, the corruption of potential purity? In what arithmetical terms shall we state the loss of shame, and the development of that less than brute view of life, which enables us to watch with unconcern the toil of infants side by side with the idleness of men?

The moral ills resulting from child labor are numerous and far-reaching. When children become wage earners and are thrown into constant association with adult workers, they develop prematurely an adult consciousness and view of life. About the first consequence of their employment is that they cease almost at once to be children. They lose their respect for parental authority, in many cases, and become arrogant, wayward, and defiant. There is always a tendency in their homes to regard them as men and women as soon as they become wage-earners. Discipline is at once relaxed, at the very time when it is most necessary. When children who have just entered upon that most critical period of life, adolescence, are associated with adults in factories, are driven to their tasks with curses, and hear constantly the unrestrained conversation, often coarse and foul, of the adults, the psychological effect cannot be other than bad. The mothers and fathers who read this book need only know that children, little boys and girls, in mills and factories where men and women are employed, must frequently see women at work in whom the signs of a developing life within are evident, and hear them made the butt of the coarsest taunts and jests, to realize how great the moral peril to the adolescent boy or girl must be.
