I have no intention of exhausting the whole category of diseases to which man--and therefore the soldier--is heir, but simply to touch upon those that are most likely to occur in a campaign. The foregoing list includes, I believe, all the most likely, but to them I should like to add these two--SMALLPOX and CHOLERA. To deal first with smallpox, we can say, fortunately, that it is rare. This is due in large part to the almost universal provision of vaccination, which should be insisted upon in an army. Cholera is of rare occurrence, and nothing can be done to ward it off except to follow carefully the ordinary rules of health and sanitation. Should it, unfortunately, break out, the army must place itself unreservedly in the hands of medical authorities who are especially qualified to deal with it. There is one other disease that has made its effects felt on almost every army, and which it has been found impossible to thoroughly eliminate. The hands of those who would lessen its influence are to a great extent tied, because in the past, the only method that has been permissible to eliminate venereal disease has been what I shall call "the Moral method"--the appeal to morality and the intelligence of the individual soldier. We have used this excellent and praiseworthy method for generations, but it has never been found capable of eradicating the evil. Some other means, from an army point of view, has obviously to be resorted to. But even to discuss the matter, one runs the risk of being ruled out of court by those who will admit none but the aforementioned "moral argument."
