Sailors are another class who must sometimes need spirits, if they are needed in case of great exposure to cold and wet. But several crews have attempted to winter in high northern latitudes, and those furnished with spirits have nearly all perished, while those not furnished with them have nearly all survived. When exposed to cold and wet, and partially immersed in the sea for hours, those who have not used spirits have commonly outlived those who drank them. Soldiers are exposed to even more and severer extremes and vicissitudes than sailors. But Dr. Jackson, a most distinguished physician in the British army, asserts that spirits are decidedly injurious to soldiers on duty, rendering them less able to endure labor and hardship. And a general officer in the same army thus testifies: "But, above all, let every one who values his health, avoid drinking spirits when heated; that is adding fuel to the fire, and is apt to produce the most dangerous inflammatory complaints." "Not a more dangerous error exists, than the notion that the habitual use of spirituous liquors prevents the effects of cold. On the contrary, the truth is, that those who drink most frequently of them are soonest affected by severe weather. The daily use of these liquors tends greatly to emaciate and waste the strength of the body," etc. The Roman soldiers marched with a weight of armor upon them which a modern soldier can hardly stand under; and they conquered the world. Yet they drank nothing stronger than vinegar and water. "I have worn out two armies in two wars," says the Dr. Jackson mentioned above, "by the aids of temperance and hard work, and probably could wear out another before my period of old age arrives. I eat no animal food, drink no wine or malt liquor, or spirits of any kind; I wear no flannel, and neither regard wind nor rain, heat nor cold, when business is in the way." Those men in Europe who are trained for boxing-matches would require spirits if they were necessary for giving bodily strength and health, since the object of this training is to produce the most perfect health, and the greatest possible strength. But ardent spirits are not used by them at all; and even wine is scarcely allowed. In protracted watching by the bed of sickness, food and intervals of rest are the only real securities against disease and weakness. Spirits peculiarly expose a man to receive the disease, if it be contagious, and if not, they wear out the strength sooner than it would otherwise fail. The most exposed and trying situations in life, then, need not the aid of ardent spirits; nay, they are in such cases decidedly injurious. They are not, therefore, necessary, but injurious for men in all other situations. The distiller must, therefore, give up the necessity of using them in the community as a reason for continuing their manufacture.
