The P.M.O. laughed.

"Making a health resort of a battleship, with your dressing stations under casemates and your sick bay all but under a turret, does seem a bit like reversing the saying about 'in the midst of life we are in death,'" he replied. "But the fact remains that this ship—the whole of the Grand Fleet indeed—is one of the most remarkable 'health resorts' the world has ever known. Not since the dawn of history has there been a large body of men with so small a percentage of bodily ills and ailments as that which mans the ships of the Grand Fleet at this moment. This is due to the absolutely unique conditions which prevail here, and our success in maintaining and improving the standard of health is principally due to making the most of those conditions.

"The health of any community—of any body or collection of human beings—depends primarily upon the natural salubrity of the region in which it is located and the extent to which it is isolated from those living under less favourable conditions. A city may be very healthy naturally, but if its inhabitants are subject to a constant influx of more or less infected transients from less healthy places its own standard must inevitably be lowered. Under normal conditions, a modern warship—either in port or at sea—is one of the healthiest places in the world, and such sickness as prevails there is almost always contracted ashore and carried—and often spread—aboard.

"With a Fleet that has its base near a large city, so that the men are in more or less constant contact with those ashore, the health of the former will very largely depend upon the extent to which that contact can be controlled. Between dock-hands, etc., coming aboard and the sailors going ashore, it is difficult under such circumstances to keep the men afloat much healthier than those on the land. It is only when there is comparatively complete isolation from large cities that it is possible to take full advantage of the ideal conditions for maintaining physical healthfulness at sea, and such conditions exist at the Northern Base to a degree never before equalled in Naval history. Our success here is merely the consequence of making the most of those unique conditions.

"On the score of bodily healthfulness, life as lived in the Grand Fleet has more favouring conditions, and fewer unfavouring ones, than that possible at any other point at which a considerable fleet has ever had its base. Indeed, I could go farther than that, and say that never has a large number of men, either afloat or ashore, had such an opportunity to maintain so high a standard of physical health. In the first place, wet, cold, and stormy though it is for much of the year, the climate is a salubrious and invigorating one for the physically sound man that the sailor must be before he finds his way into the Navy at all. Even ashore the population is notably robust.

"In the next place, the anchorage is isolated, but not too isolated. It strikes almost the ideal mean on this score. In the ordinary routine, there is practically no contact whatever between those afloat and the people ashore. If the men land at all it will be for a game of football, a cross-country run, road work or something of the sort, in the course of which nothing whatever is seen of the resident population. It is not practicable to give the men a long enough shore leave to allow them to visit a neighbouring town, where one sees rather less navy blue as a rule than in many an inland town in England. The steward doing his marketing is about the only regular human link between a ship and the land, and his contact with those on shore is not of a character likely to be dangerous. This leaves the fresh drafts and the men returning from leave as almost the only possible carriers of new infection. How those are looked after I will explain presently.

"Much more complete isolation than this is, of course, effected when a cruiser or a fleet of cruisers goes on an extended voyage or patrol, but in such a case the freedom from contact with shore is offset by the more arduous conditions of life, especially in the matter of diet. The great thing about the situation of Scapa is that its unique position makes it possible to eliminate most of the rigors of sea life without being exposed to the health dangers of harbour life. A ship here can be just as well victualled as at Portsmouth, so far as the men are concerned, while letters and newspapers six times a week are ample service on that score. As I have said, the conditions for keeping mind and body at their best are ideal, and give us a unique opportunity for establishing new health records for the Navy.

"Of the two main channels by which disease could come to us from the outside—returning leave men and new drafts—the latter is the more dangerous, and therefore the one the more closely watched. Generally speaking, the men get leave about every nine months, this more or less roughly coinciding with a period in which the ship is in dock for repairs. If during a man's leave there is a case of any infectious or contagious disease in the house where he has stayed, or if he has reason to believe that he may have been exposed to infection or contagion elsewhere, he is ordered to report that fact immediately upon his return to the ship, when we take such precautions as the circumstances seem to warrant to prevent trouble. His clothes are disinfected, and he is ordered to report for examination over a period of days varying with the disease to which there was risk of his having been exposed. This enables us to isolate him (should it be necessary) before he is in a condition in which he could pass on the disease to others. A useful check which we have upon a man who might neglect to report his possible exposure to disease during his leave is the law which requires medical officers in all parts of Great Britain to ascertain if any soldier or sailor on leave is living in any house where there is a case of infectious disease, and to report this fact to the proper authorities. In this way it may be that we learn a man has been exposed even before he returns to the ship.

"New drafts are watched equally closely. Some time before a man's arrival a health sheet is sent to me on which is indicated any disease which he may have had during his period of service, together with information as to whether or not he may have been exposed to anything infectious in the interval immediately before he is sent to us. Any treatment for minor chronic ailments which may be in progress is continued in the ship. A general disinfection of kit and a daily reporting for twenty-one days for examination makes it practically impossible for a new rating to bring disease to the Ship's Company.

"The greatest obstacle to the preservation of perfect health in the men on a warship is the unavoidable necessity of having them sleep close together in comparatively confined spaces. This ship, from the fact that she was originally designed for a foreign Power, is worse off than most modern battleships on that score, and, everything else equal, would be more difficult to keep the men in health in than in any of the others. This is one of the reasons why I am so gratified by our showing of the past week. Sleeping in hammocks in itself is not unhealthy—quite the contrary, in fact—but the danger lies in the chance an infectious disease has to spread among so many men lying almost side by side and head to feet. Thorough ventilation is the best preventive of disease under the circumstances; this has been provided by fans.
