strongest arguments which has the strongest organized force. It need scarcely be said that the successful piercing of the Central American Isthmus at any point may precipitate the moment that is sure to come sooner or later. The profound modification of commercial routes expected from this enterprise, the political importance to the United States of such a channel of communication between her Atlantic and Pacific seaboards, are not, however, the whole nor even the principal part of the question. As far as can be seen, the time will come when stable governments for the American tropical States must be assured by the now existing powerful and stable States of America or Europe. The geographical position of those States, the climatic conditions, make it plain at once that sea power will there, even more than in the case of Turkey, determine what foreign State shall predominate,—if not by actual possession, by its influence over the native governments. The geographical position of the United States and her intrinsic power give her an undeniable advantage; but that advantage will not avail if there is a great inferiority of organized brute-force, which still remains the last argument of republics as of kings. Herein lies to us the great and still living interest of the Seven Years’ War. In it we have seen and followed England, with an army small as compared with other States, as is still her case to-day, first successfully defending her own shores, then carrying her arms in every direction, spreading her rule and influence over remote regions, and not only binding them to her obedience, but making them tributary to her wealth, her strength, and her reputation. As she loosens the grasp and neutralizes the influence of France and Spain in regions beyond the sea, there is perhaps seen the prophecy of some other great nation in days yet to come, that will incline the balance of power in some future sea war, whose scope will be recognized afterward, if not by contemporaries, to have been the political future and the economical development of regions before lost to civilization; but that nation will not be the United States if the moment find her indifferent, as now, to the empire of the seas.
