Note.—At the time of closing the forms for the last signature of this book, there is available no tabulated statement of the total cost of the great World War, nor even to the signing of the armistice. But in a speech in San Francisco, March 18, 1919, telegraphed all over the country and quoted in the papers of the following day, Secretary of War Newton D. Baker stated that “the cost of the war alone was $197,000,000,000, or $11,000,000,000 more than the total property value of all North America.” To enable the mind to grasp the significance of these figures, the Secretary further said, “No child born in a civilized nation in the next hundred years will escape paying a considerable portion of the debt this war has brought about.” According to a dispatch sent out March 26, 1919, by the British wireless service, and printed in the American papers of the 27th, “Edgar Crammond, a prominent British financial writer, estimates the direct cost of the war to the Allies at $141,800,000,000, and to the Central European powers at $68,375,000,000. He estimates the total cost of the war, including indirect losses, at $260,000,000,000. There has been nothing, he says, approaching this destruction of capital wealth in the history of the world.”-Eds. SBBS 583.2
