It often happens that the places that have the best position are weak in strength and resources; a notable instance is Gibraltar, another is Culebra, and the most notable of all is Guam. None of these places is fortunate in either resources or natural strength, though Gibraltar was strong for the artillery of the time when the base was established there. In fact, it is hard to think of any place that combines in itself the three advantages of a fine strategical position, large resources, and great strength. The three attributes seem almost incompatible; for how can a base far distant from its home be well placed with reference to attacking the lines of communication of any enemy intending to attack the home coast, and yet have its own lines of communications safe? How can it have a sheet of water, just deep enough but not too deep to anchor a large fleet in, with all of its auxiliaries extensive enough to accommodate all the vessels and far enough from the sea to be safe from gun-fire, and yet be on an island so small and so rugged, that an enemy could not land troops near the base and capture it from the land side, as the Japanese captured Port Arthur? The natural strategic advantages of a large and sheltered sheet of water seem to entail the disadvantages of a large island, or a continent. There seems only one way in which to solve the problem of where and how to establish a permanent naval base at a distant point, and that is the way in which the world's preceptor--Great Britain--has solved it; and the solution is to select a place that has already the advantage of position, and then add to it the artificial advantages of resources and military strength. This brief statement makes the matter seem a little too simple; and so it will have to be modified by adding that the mere fact of a place having a fine position is not quite sufficient, because the place must be of such a character that it is capable of having resources and strength added to it; a sharp pinnacle rock in the middle of the Mediterranean, for instance, might have a fine strategic position, and yet be unavailable as a naval base. Even here, however, we must pause to note that energy and will could do much toward making even a pinnacle rock a naval base; for we see the gigantic fortress of Heligoland erected on what was little but a shoal; and we see the diminutive water areas of Malta and Gibraltar made to hold in safety the war-ships of the greatest navy in the world.
