The necessity of building and maintaining an adequate navy, well balanced, thoroughly equipped and maintained at the highest standard of efficiency and ready always for immediate service, with necessary adjuncts afloat and ashore, is also one of the clear lessons of the war; others are the establishment of ammunition plants at points sufficiently remote from the seacoast, and so placed as to render their capture and destruction improbable in case of sudden invasion; the provision of an adequate reserve corps of 50,000 officers, a number sufficient for one and one-half million of citizen soldiers; officers well trained and ready for immediate service; the provision of adequate supplies and reserve supplies of artillery, arms, and ammunition of all types for these troops. We must also build up a system under which officers and men for our citizen soldiery can be trained with the minimum of interference with their educational or industrial careers, under conditions which will permit the accomplishment of their training during the period of youth, and once this is accomplished will permit their return to their normal occupations with the minimum of delay. The lesson which we should draw from the Great War is that nothing should be left to chance or to the promise of others, or to the fair-weather relations of to-day; that we should be as well prepared, and as well organized on land as Switzerland, a nation without a trace of militarism, and yet so thoroughly prepared and so thoroughly ready and able to defend herself that to-day her territory is inviolate, although she is surrounded by warring nations. Belgium to-day is an illustration of what may be expected from lack of adequate preparedness. The great outstanding lesson of the war is that we must not trust to righteousness and fair dealing alone; we must be prepared to play our part, and while loving justice and dealing fairly with others, we must be always ready to do our full duty, and to defend our country with force if need be. If we do not, we shall always be helpless and at the mercy of our enemies. We can be strong, yet tolerant, just, yet prepared to defend ourselves against aggression. Another lesson is that our military establishment on land and sea should not be dependent upon a system of militia and volunteers. These will not be found adequate under the conditions of modern war, and above all we should appreciate the fact that our military system must be founded upon _equality of service, rich and poor alike_. We must while extending equality of privilege to all, including the thousands who are coming to us every day, insist upon equality of obligation by all. With the privileges of citizenship must go the obligations and responsibilities not only in peace but also in war.
