"16. Do not go, with loose hair or flowing garments, near dangerous machinery. "17. Never touch gunpowder after dark. "18. Never fondle a strange dog. "19. Never light a fire with kerosene. "20. Fill and trim your lamps in the day-time. Never trim or fill a lighted lamp. "21. Keep matches in a closed metallic box. "22. Have your horses rough-shod as soon as the ground freezes. "23. When feeling dizzy or seasick, lie down. "24. Do not close the damper of your stove too early. Better waste coal than run the risk of suffocation by gas. "25. When climbing a ladder, look up and not down. "26. In railroad traveling take the center of the car, and the middle car of the train, for safety. "27. Eat only pure food, drink only pure liquids, think only pure thoughts, and keep your blood pure. "28. In going through dry woods or over prairies do not smoke or cast matches about carelessly. There should be laws against this often wanton destruction of property. "29. Look out for spontaneous ignition of oily rags, oil-painted canvas rolled up, wet iron filings. "30. In entering mines not used, always try for gas before venturing into them. "31. Do not be careless in any way whatever in connection with fire. The losses in the United States, in 1889, by fires as a result of carelessness amounted to nearly $100,000,000, while in San Francisco for the same year we find that fully 80% of the losses can be attributed to the same source." =Alcohol.=--Felix L. Oswald, M.D., gives some very good ideas in _Good Health_ on the alcoholic habit. "'Reform,' says an able political writer, 'is ever unpopular. All wrongs lie in the consent of the wronged, and what with the fierce support of those who thrive on the abuse, and the dull, heavy, ignorant conservatism of the masses, * * * it is a sad delusion to suppose that the cause is won when the argument is made.' An unquestionable preponderance of power, they argue, favors the side of the liquor venders, and in this world, at least, always finds a way to assert itself as right. The last link of that syllogism, however, is a rule with occasional exceptions. No unqualified evil has ever succeeded in maintaining its supremacy, and the evils of the alcohol vice are offset by no benefits. Alcohol has been called 'negative food,' because its physiological influence torpifies the functional energy of the digestive organs, and thus, for a time, renders the toper insensible to the cravings of hunger. The same effect, however, can be produced by a stunning blow, and we might as well claim that the interests of political economy could be promoted by a fierce war, because a knock-down stroke with the butt-end of a musket is apt to lessen the appetite of the afflicted soldier. No real benefit can result from the lethargizing effect of a poison dose, the retardation of the digestive functions being in every case a morbid and abnormal process, avenging its repetition by the fatty degeneration of the tissues and the
