A soldier should be in training always. Compelled to spend nine tenths of his time in laboriously doing nothing, he is called upon occasionally, for a few hours or days or weeks, to put forth exertions which task human endurance to the uttermost. The soldier, too, of all men, should have quiet nerves; for the phantoms of war scare more men than its real dangers, and men's bodies can shake when their souls are firm. That two and two make four is not a truth more unquestionably certain than that smoking does diminish a soldier's power of endurance, and does make him more susceptible to imaginary dangers. If a regiment were to be raised for the hardest service of which men can ever be capable, and that service were to be performed for a series of campaigns, it would be necessary to exclude from the commissariat, not tobacco only, but coffee and tea. Each man, in short, would have to be kept in what prize-fighters call "condition"; by which term they simply mean the natural state of the body, uncontaminated by poison, and unimpaired by indolence or excess. Every man is in duty bound to be "in condition" at all times; but the soldier,--it is part of his profession to be "in condition." When remote posterity comes to read of the millions and millions of dollars expended during the late war in curing soldiers untouched by bayonet or bullet, the enthusiasm of readers will not be excited by the generosity displayed in bestowing those millions. People will lay down the book and exclaim: "How ignorant were our poor ancestors of the laws of life! A soldier in hospital without a wound! How extremely absurd!"
