Administration being a term of very general application, it will be expected that that of the navy should present close analogies, and even points of identity, with other forms of administration; for instance, that in it, as elsewhere, efficiency of result will be better secured by individual responsibility than by collective responsibility. But, along with general resemblance, naval administration is very clearly and sharply differentiated by the presence of an element which is foreign to almost all other activities of life in countries like Great Britain and the United States. The military factor is to it not merely incidental, but fundamental; whatever other result may be achieved, naval administration has failed unless it provides to the nation an efficient fighting body, directed by well-trained men, animated by a strong military spirit. On the other hand, many of the operations connected with it differ from those common to civil life only in a certain particularity of method. This is true in principal measure of the financial management, of the medical establishment, and to a considerable though much smaller degree of the manufacturing processes connected with the production of naval material. The business routine of even the most military department of a naval administration is in itself more akin to civil than to military life: but it by no means follows that those departments would be better administered under men of civil habits of thought than by those of military training. The method exists for the result, and an efficient fighting body is not to be attained by weakening the appreciation of military necessities at the very fountain head of their supply in the administration. This necessary appreciation can be the result only of personal experience of good and bad through the formative period of life. We find, therefore, at the very outset of our inquiry two fundamental yet opposing elements, neither of which can be eliminated. Nor can they be reconciled, in the sense of becoming sympathetic. In its proper manifestation the jealousy between the civil and military spirits is a healthy symptom. They can be made to work together harmoniously and efficiently; to complement, not to antagonize each other; provided means are taken to ensure to each its due relative precedence and weight in the determination of practical questions.
