_Military and Naval Expenditures._--The expenditures on account of the military and naval establishments have increased enormously in recent years. Before the war with Spain the appropriations for the maintenance of the army did not exceed $50,000,000 per annum. The budget of expenditures for the year 1922 as submitted to Congress by the President aggregated nearly $4,000,000,000. It contained the following items: war department, $390,000,000; navy, $478,000,000; pensions, $258,000,000; veterans bureau, $438,000,000; interest on the national debt, $976,000,000; total, $2,539,000,000, or more than 60 per cent of the total, leaving less than 40 per cent for civil purposes. In the hope of bringing about an agreement among the nations for a reduction of their military and naval expenditures, a conference of the Powers, called by President Harding, assembled at Washington in November, 1921. Here an agreement was reached to reduce naval expenditures. _Volunteers._--Except during the Civil War and the war with Germany, resort has never been made to conscription for recruiting the army--a practice almost universal in Europe. In most of our wars the chief reliance has been on volunteers and the militia. Thus at the outbreak of the Civil War the President was authorized to accept the services of 500,000 volunteers, and at the outbreak of the war with Spain in 1898, the President called for 200,000 volunteers. It takes much training to convert an inexperienced volunteer into an efficient soldier; but many of our great battles have been fought chiefly by the volunteer forces. =The Militia.=--The Constitution also authorizes Congress to provide for calling forth the militia to execute the laws of the Union, suppress insurrections, and repel invasions; and to provide for organizing, arming, and disciplining the militia, and for governing such part of them as may be employed in the service of the United States. The militia as defined by act of Congress consists of all able-bodied male citizens of the United States between the ages of eighteen and forty-five. That portion of the militia regularly organized, uniformed, and occasionally drilled and taught military tactics constitutes the national guard.[52] [52] The actual strength of the national guard in 1921 was about 113,600 men. But the plans for its development contemplate an ultimate strength of 425,000 men.
