Whatever the argument advanced in favor of teaching the younger personnel, from books, the lessons learned by older officers, through long years of association with service conditions, it is always answered by the old and narrow adage “ Experience is the best teacher. Usually follows a sniff or two of contempt at the idea that such an involved thing as experience could be dealt with as anything but the most illusive and incommunicable subject. Then follow discouraging remarks, expressing the general idea that that very idea is folly itself and that experience cannot even partly be taught from books. This last, presumably because there are no books from which to teach it.
The product of the teachings of experience is a man who can handle men; who knows how, in time of stress and excitement, to handle casualties; and who knows as a result of his experience the kind of casualties, accidents, mismanagements, mistakes and misjudgments to look out for and correct.
