Tobacco is Not a Natural Taste. As might be expected, in the case of such an utterly useless drug, we have no natural liking or instinct for it; and the taste for it has to be acquired just as in the case of alcohol, only as a rule with greater difficulty and with more painful experiences of headache, nausea, and other discomforts.

A BOARD OF HEALTH EXAMINATION FOR WORKING PAPERS

The Board of Health of the City of New York requires that all children between the ages of fourteen and sixteen shall have certificates of good health before they can be employed in business. Any employer who hires a child without such a certificate is liable to a heavy fine. This law is to protect the health of both the worker and the public.

Nicotine, a Powerful Poison. Tobacco contains and depends largely for its effects upon considerable amounts of a substance called nicotine. This is a powerful poison, even in very small doses, with only feeble narcotic, or pain-deadening, powers; but fortunately, the larger part of it is destroyed in the process of burning. Enough, however, is carried over in the smoke, or absorbed through the butt of the cigar or cigarette, or the mouth-piece of the pipe, to injure the nervous system, especially in youth. As will be seen in the chapter upon the "Care of the Heart," it especially attacks the nerves supplying the heart, and is thus most harmful to growing boys.

A TEST OF CLEAR HEAD AND STEADY NERVES

The boy who smokes cigarettes finds it increasingly difficult to obtain a position in a bank or other large commercial house.

On account of its injurious effects upon the nerves of the heart, smoking has long been forbidden by trainers and coachers to all athletes who are training for a contest or race. In addition to its poisonous effects upon the nervous system, tobacco also does great harm to boys and young men by providing them with an attractive means of filling up their time and keeping themselves amused without either bodily or mental effort. The boy who smokes habitually will find it much easier to waste his time in day-dreams and gossip, and tends to become a loafer and an idler.

The Advantage that Non-Smokers have over Smokers. When both of these influences are taken together, it is little wonder that the investigations of Dr. Seaver, the medical director of Yale, showed that out of the 187 men in the class of 1881, those not using tobacco during their college course had gained, over the users of tobacco, twenty-two per cent in weight, twenty-nine per cent in height, nineteen per cent in growth of chest, and sixty-six per cent in increase of lung capacity.
