[The remainder of the essay considers the vital problem of supplying the navy with trained men, both in active service and in reserve. It is pointed out that, of the two systems, compulsory enlistments for short service and voluntary enlistments for long service, the second system, which is the one employed by the United States, produces fewer though better trained reserves; and it therefore necessitates a larger standing force.—EDITOR.] PART II SEA POWER IN HISTORY 15. A NATION EXHAUSTED BY ISOLATION[41] _France under Louis XIV_ The peace signed at Ryswick in 1697 was most disadvantageous to France; she lost all that had been gained since the Peace of Nimeguen, nineteen years before, with the single important exception of Strasburg. All that Louis XIV had gained by trick or force during the years of peace was given up. Immense restitutions were made to Germany and to Spain. In so far as the latter were made in the Netherlands, they were to the immediate advantage of the United Provinces, and indeed of all Europe as well as of Spain. To the two sea nations the terms of the treaty gave commercial benefits, which tended to the increase of their own sea power and to the consequent injury of that of France. France had made a gigantic struggle; to stand alone as she did then, and as she has since done more than once, against all Europe is a great feat. Yet it may be said that as the United Provinces taught the lesson that a nation, however active and enterprising, cannot rest upon external resources alone, if intrinsically weak in numbers and territory, so France in its measure shows that a nation cannot subsist indefinitely off itself, however powerful in numbers and strong in internal resources.
