The occupation of the mind has a great influence upon the health of the body.

There is no employment so dangerous and destructive to life but plenty of human beings can be found to engage in it. Of all the instances that can be given. of recklessness of life, there is none which exceeds that of the workmen employed in what is called dry-pointing—the grinding of needles and of table forks. The fine steel dust which they breathe brings on a painful disease, of which they are almost sure to die before they are forty. Yet not only are men tempted by high wages to engage in this employment, but they resist to the utmost all contrivances devised for diminishing the danger, through fear that such things would cause more workmen to offer themselves and thus lower wages. Many physicians have investigated the effects of work in the numerous match factories in France upon the health of the employees, and all agree that rapid destruction of the teeth, decay or necrosis of the jawbone, bronchitis, and other diseases result.

We will probably find more old men on farms than elsewhere. There are many reasons why farmers should live longer than persons residing in cities or than those engaged in other occupations. Aside from the purer air, the outdoor exercise, both conducive to a good appetite and sound sleep, which comparatively few in cities enjoy, they are free from the friction, harassing cares, anxieties, and the keen competition incident to city life. On the other hand, there are some great drawbacks and some enemies to longevity, even on the farm. Man does not live by bread alone. The mind is by far the greatest factor in maintaining the body in a healthy condition. The social life of the city, the great opportunities afforded the mind for feeding upon libraries and lectures, great sermons, and

constant association with other minds, the great variety of amusements compensate largely for the loss of many of the advantages of farm life. In spite of the great temperance and immunity from things which corrode, whittle, and rasp away life in the cities, farmers in many places do not live so long as scientists and some other professional men.

There is no doubt that aspiration and success tend to prolong life. Prosperity tends to longevity, if we do not wear life away or burn it out in the feverish pursuit of wealth. Thomas W. Higginson made a list of thirty of the most noted preachers of the last century, and found that their average length of life was sixty-nine years.

Among miners in some sections over six hundred out of a thousand die from consumption. In the prisons of Europe, where the fatal effects of bad air and filth are shown, over sixty-one per cent. of the deaths are from tuberculosis. In Bavarian monasteries, fifty per cent. of those who enter in good health die of consumption, and in the Prussian prisons it is almost the same. The effect of bad air, filth, and bad food is shown by the fact that the death-rate among these classes, between the ages of twenty and forty, is five times that of the general population of the same age. In New York City, over one-fifth of all the deaths of persons over twenty are from this cause. In large cities in Europe the percentage is often still greater. Of one thousand deaths from all causes, on the average, one hundred and three farmers die of pulmonary tuberculosis, one hundred and eight fishermen, one hundred and twenty-one gardeners, one hundred and twenty-two farm laborers, one hundred and sixty-seven grocers, two hundred and nine tailors, three hundred and one dry-goods dealers, and four hundred and sixty-one compositors,—nearly one-half.

According to a long series of investigations by Drs.

Benoysten and Lombard into occupations or trades where workers must inhale dust, it appears that mineral dust is the most detrimental to health, animal dust ranking next, and vegetable dust third.

In choosing an occupation, cleanliness, pure air, sunlight, and freedom from corroding dust and poisonous gases are of the greatest importance. A man who would sell a year of his life for any amount of money would be considered insane, and yet we deliberately choose occupations and vocations which statistics and physicians tell us will be practically sure to cut off from five to twenty-five, thirty, or even forty years of our lives, and are seemingly perfectly indifferent to our fate.

There is danger in a calling which requires great expenditure of vitality at long, irregular intervals. He who is not regularly, or systematically employed incurs perpetual risk. "Of the thirty-two all-round athletes in a New York club not long ago," said a physician, "three are dead of consumption, five have to wear trusses, four or five are lop-shouldered, and three have catarrh and partial deafness." Dr. Patten, chief surgeon at the National Soldiers' Home at Dayton, Ohio, says that "of the five thousand soldiers in that institution fully eighty per cent. are suffering from heart disease in one form or another, due to the forced physical exertions of the campaigns."

Man's faculties and functions are so interrelated that whatever affects one affects all. Athletes who overdevelop the muscular system do so at the expense of the physical, mental, and moral well-being. It is a law of nature that the overdevelopment of any function or faculty, forcing or straining it, tends not only to ruin. it, but also to cause injurious reactions on every other faculty and function.

Vigorous thought must come from a fresh brain. We cannot expect nerve, snap, robustness and vigor,
