+Tobacco a serious injury to growing persons.+--On this point all teachers are unanimous. Statistics taken at the naval school at Annapolis, at Yale College, and elsewhere, show that the use of tobacco is the exception with scholars at the head, and the rule with scholars at the foot of the class. Shortly after we began to take statistics on this point in Bowdoin College I asked the director of the gymnasium what was the result with the Freshman class? "Oh," he said, "the list of the smokers is substantially the same as that which was reported the other day for deficiencies in scholarship." A prominent educator, who had given considerable attention to this subject, after spending an hour in my recitation room with a class of college seniors, indicated with perfect accuracy the habitual and excessive smokers, simply by noting the eye, manner, and complexion. Tobacco, used in early life, tends to stunt the growth, weaken the eyes, shatter the nervous system, and impair the powers of physical endurance and mental application. No candidate for a college athletic team, or contestant in a race, would think of using tobacco while in training. Every man who wishes to keep himself in training for the highest prizes in business and professional life must guard his early years from the deterioration which this habit invariably brings. THE PENALTY. +These vices bring disease and disgrace.+--These vices put in place of physical well-being the gratification of a particular taste and appetite. Hence they bring about the abnormal action of some organs at the expense of all the rest; and this is the essence of disease. A diseased body causes a disordered mind and an enfeebled will. The excessive and over-stimulated activity of one set of organs involves a corresponding defect in the activity and functions of the other faculties. The glutton or drunkard neglects his business; loses interest in reading and study; fails to provide for his family; forfeits self-respect; and thus brings upon himself poverty and wretchedness and shame. He sinks lower and lower in the social scale; grows more and more a burden to others and a disgrace to himself; and at last ends a worthless and ignominious life in an unwept and dishonored grave. CHAPTER II. Dress. Next in importance to food and drink stand clothing and shelter. Without substantial and permanent protection against cold and rain, without decent covering for the body and privacy of life, civilization is impossible. The clothes we wear express the standing choices of our will; and as clothes come closer to our bodies than anything else, they stand as the most immediate and obvious expression of our mind. "The apparel oft proclaims the man." THE DUTY.
