The wanderer on his travels, the soldier in camp or battle, have often neither time nor opportunity to refresh themselves with a meal, or to recruit strength by a good rest. With them it is important to complete their journey or task, and to rest afterwards. A common workman may, at times, be in the same situation. In such cases a little brandy is of great service. It increases vital activity and courage; in many countries the army is for this reason permitted to use liquor, although, of course, sparingly. Having now spoken of the medicinal use of liquor, we wish to examine more closely its dangers, and to explain the reason why its enjoyment is to many so great a temptation as often to become a passion. A slight quantity of liquor taken at breakfast, makes one feel increased vital activity. The pulse beats quicker, the mind is stirred up, digestion easier, and before the food has been transformed into blood, we feel animated to vigorous bodily activity and motion. The enjoyment of spirit fills the long pause between the meal itself and its change into blood. He who feels exhausted and eats, has yet but satisfied the demands of the stomach, without therewith replenishing his blood. It takes a long time, often from five to six hours, before the blood is directly benefited. It is owing to this, that after dinner we do not feel lively, but inactive, disposed to rest. Now, he who after dinner cannot rest, but must continue to work, is anxious to stimulate himself by a dram of liquor, because this will act more quickly than the food he has taken. The spirits he took fill the long pause which exists between his meal and its complete transformation into blood. Is it any longer surprising, that it is the workmen who mostly are subject to the use of spirits? No, we are not surprised; we feel sorry that they are not taught better; that instead of imparting to the people a knowledge of things useful to the preservation of health, we constantly remind them of the "devil and hell;" and that in place of teaching them, by the study of nature, how to avoid errors and dangers, we merely try to frighten them with future punishments. The danger of spirits consists in this, that their good qualities, their advantageous effects, manifest themselves immediately, while their evils appear later. Liquor is not unlike a man whose virtues are laid open to every one; whose vices, however, are hidden, and who therefore is seductive and dangerous. If we wish to warn our fellow-men against such a one, we must not do it by denying or concealing his virtues; on the contrary, we must openly tell all his good qualities; the warning in which we lay bare his vices, will then be more, all the more readily heeded. True, liquor is a medicine; but, like every other medical remedy, it becomes poisonous in the body of him who puts himself continually in such a condition as to be obliged to use it.
