A coalition between these two countries would be an ideal arrangement, because it would enable each country to force us to grant the conditions it desires, and secure a large indemnity besides. Would Great Britain interfere in our behalf? This can be answered by the man so wise that he knows what the international situation and the commercial situation will be ten years hence. Let him speak. WILL THE IMPORTANCE OF NAVAL POWER INCREASE OR DECREASE? It is clear that the importance to a country of a navy varies with two things--the value of that country's foreign trade and the probability of war. It is also clear that, other things being equal, the probability of a country becoming involved in war varies as the value of her foreign trade; because the causes of friction and the money at stake vary in that proportion. Therefore, _the importance to a country of her navy varies as the square of the value of her foreign trade_. In order to answer the question, therefore, we must first consider whether foreign trade--sea trade--is going to increase or decrease. As to the United States alone, the value of our exports is about ten times what it was fifty years ago, and it promises to increase. But the United States is only one country, and perhaps her increase in foreign trade has been due to conditions past or passing. So what is the outlook for the future, both for the United States and other countries? Will other countries seek foreign trade? Yes. The recent commercial progress of Germany, Argentina, and Japan, shows the growing recognition by civilized and enterprising countries of the benefits of foreign trade, and of the facilities for attaining it which are now given by the advent of large, swift, modern steamers; steamers which are becoming larger and swifter and safer every year, more and more adapted for ocean trade. For not only have the writings of Mahan brought about an increase in the sea power of every great country; but this increase has so aroused the attention of the engineering professions that the improvement of ships, engines, and other sea material has gone ahead faster than all the other engineering arts. The reason why the engineering arts that are connected with the sea have gone ahead more rapidly than any other arts is simply that they are given wider opportunity and a greater scope. It is inherent in the very nature of things that it is easier to transport things by water than by land; that water transportation lends itself in a higher degree to the exercise of engineering skill, to the attainment of great results.
